An application was made by William Henry Mounsey on 29th April 1907 for letters patent for an "improved matrix cleaner for linotype machines." The specification was as follows (omitting formal parts) : -

"This invention is for the purpose of automatically cleaning the matrices of linotype machines every time they have been used and before they are placed in the magazine, and consists of two pairs of brushes, one pair being fixed on to the intermediate elevator channel plate, and another pair being fixed on to the distributor box, in such manner that the matrices, in being dis- tributed from each line, shall pass the brushes one of each pair of which will rub against and clean the front side and the other the back side." (The specification then described the invention in detail by reference to drawings, and continued) : -

" After the line has been set and the type has been cast, and the matrices are being distributed, they pass the first pair of brushes attached to the intermediate elevator channel plate, and then later on they pass the second pair of brushes attached to the distributor box, and in so passing, the brushes remove all impurities from the matrices, which are deposited in the magazine in a clean condition ready to be used again.

"Tam aware that single brushes have been fixed on or behind the distributor beam of linotype machines, by which one side

only of the matrices ean be cleaned, and I disclaim the sole right of making such, my invention having reference to double brushes placed on the intermediate channel plate and on the distributor box of linotype machines.

" Having now fully described and ascertained my said inven- tion and the manner in which it is to be performed, I declare that what I claim is : -

"In linotype machines two or more brushes attached to the intermediate elevator channel plate and two or more brushes attached to the front and back plate of the distributor box for the purpose of automatically brushing and cleaning both sides of the matrices after they have been used for forming a line of type and before they are distributed into the magazine all substantially as described and shown."

The application was opposed by the Linotype Co. Ltd. (in liquidation), of London, England, on the grounds : -

"(1) That the invention is not novel or has been already in possession of the public with the consent or allowance of the inventor.

"(2) That the invention has been described in a book or other printed publication published in the Commonwealth before the - date of the application or is otherwise in the possession of the public."

Both objections were founded upon the specification of a patent for "improvements in linotype machines" granted to William Henry Lock and Henry John Gardner in England and published in the Commonwealth before the date of the application. The material portions of this specification are set out in the judgment of Griffith C.J. hereunder.

The Commissioner having dismissed the opposition, the op- ponents now appealed to the High Court from his decision.

Mann and Sproule, for the appellants. It being admitted that a single brush was used for cleaning one edge of the matrix, and might be used in any place in the course taken by the matrix, the use of a pair of brushes is not novel within the meaning of see. 56 of the Patents Act 1903. The objection of want of novelty could not be taken in England to an application for a

patent, although it might be in an action in which the validity H. C. or A.

of the patent was in question. Under that objection the opponent

may show that there is not sufficient inventiveness to distinguish ,,xoryer Uo.

the invention for which a patent is sought from the machine which was already known: Morgan & Co. vy. Windover & Co (1); In ve Hedge's Application (2). Want of invention is a sub- division of want of novelty : Edmunds on Patents, 2nd ed., p. 81. "To be new in a patent sense it is necessary that the novelty must show invention": Blakey & Co. v. Latham & Co. (3). "In order to sustain a patent for an article it must be new in the sense that the making of it involved an amount of invention": American Braided Wire Oo. v. Thomson & Co. (4); Thomson vy. American Braided Wire Co. (5).

Levinson, for the respondent. Most of the cases relied on for the appellants are cases of infringement. In the case, however, of an application for a patent, the application will not be refused unless the grounds of opposition are clearly made out, and where the ground of opposition is want of novely it must be shown that the invention sought to be patented and that already in use are substantially identical: Hdmwnds on Patents, 2nd ed., p. 256; Tolson's Patent (6).

[Isaacs J. referred to Moore & Hesketh v. Phillips (7); In re Nanhsen's Application (8).]

From Lock's specification it cannot be said that a person without the necessity of making experiments would arrive at the applicant's invention: Savage v. D. B. Harris & Scns (9): - "Unless it can be said that the differences are practically imma- terial, that there is no ingenuity in the second invention, no experiment necessary to show whether it can be usefully carried out or not, the second cannot be said to have been anticipated by the first": Gadd v. Mayor &c., of Manchester (10); Frost on Patents, 3rd ed., p. 147; Willmunn v. Petersen (11).

The improvement on the old machine need not be great. It : is sufficient that there is an improvement. [He also referred to Betts v. Menzies (1); Frost on Patents, 3rd ed., vol. 1, pp. 404, 462; Booth v. Kennard (2).]

Mann, in reply, referred to Spencer v. Jack (3). [Isaacs J. referred to Saaby v. Gloucester Waggon Co. (4). Hicerys J. referred to In ve Lodd's Application (5).]

GrirritH C.J. The respondent's application is for an "Improved matrix cleaner for linotype machines." The appellants gave notice of opposition to the grant on two grounds - (1) that the invention was not novel, (2) that it had been already described in a publica- tion published in the Commonwealth.

The general principles of linotype machines are now tolerably well known, but it is necessary for the proper understanding of the questions raised on this appeal to give a short description of them. Under the original system the letters or symbols to be printed were formed in relief at the end of small pieces of metal so shaped as to be capable of being fitted close together so as to form con- nected lines of type from which a print could be taken, either directly or by means of an intermediate mould taken from the type, and from which in turn a fresh cast could be taken. Under the new system the letters are no longer formed in relief upon the end of the blocks, but are formed in intaglio on one edge of a small flat metallic plate, called a matrix, which is rectangular in form, having projecting shoulders at each of its four corners, and is of such a thickness as to represent the space to be occupied by the letter in the printing when set up. The edges of this plate are at a sharply defined right angle to its surfaces. On one edge of the matrix the mould of the letter which is to be printed by means of it is sunk in a recess. On the opposite edge, which has no recess, the same letter is marked on the surface. This is

r (4) 7Q.B.D., 305, at p. 307; W.N. 2H. &N., 84. (1882), 102.

spoken of as the indicating letter. From the upper edge of the H.C. or A.

matrix a portion is removed, so as to form a V shaped cut with

straight sides, on each of which are small serrations so devised Ljsorvee Co.

that the matrix can be suspended by means of them upon a bar of corresponding shape and with like serrations, called the dis- tributing bar, at a stage in the operation of the machine to which I will directly refer.

When the machine is to be put into operation the matrices are collected or stored in separate compartments or magazines at the top of the machine. The compositor, instead of picking up a type and placing it in a composing stick, touches a key in a key-board, the effect being that the desired letter automatically leaves its magazine and descends by a properly constructed channel to a receptacle called the "assembly box," in which the matrices take up their position in due order until a complete line of type is assembled. The intaglio edges of the matrices are away from the compositor, but the indicating letters are visible to him, so that he can detect any error. The line thus "assembled" is then moved on until it comes opposite a receptacle containing molten type metal, which, being forced against the intaglio edges of the matrices, takes an impression or cast of the whole line. This is removed and used in the ordinary way for print- ing. The matrices then pass onwards through a series of channels or conduits constructed for the purpose, until they reach the part of the machine where the magazines are placed, into which they are automatically returned. For the greater part of the journey they travel closely pressed together, as when in the assembly box, the edges presenting a continuous surface. They are during this portion of their passage supported by the projecting shoulders already mentioned, which fit into grooves cut in the walls of the channels through which they pass. Upon approaching the place of distribution, however, they pass under a bar called the dis- tributing bar, so constructed as to fit into the V shaped cut in the top of the matrix, having serrations on each side adapted to those of the matrices, and so devised that the matrices at first hang from the bar, but as each matrix comes above its own magazine the support fails, and the matrix drops into the magazine, ready to be summoned again by the compositor at the key-board. At

this stage the matrices are no longer pressed together, but are - separated by short intervals so as to allow them to drop succes- sively as they come above their respective magazines. At several parts in the traverse, then, the matrices present a con- tinuous surface, and are close to the wall of the channel through which they are passing, but at the final stage they are separated, and their edges are not in contact with the channel.

In the course of use the edges carrying the indicating letters are apt to become dirty, so that the letters are scarcely legible, and means have been devised for cleaning them by means of brushes fixed so as to project through the walls of the channels or conduits and come in contact with the letters as they pass before them.

All this is common knowledge, i.c., to persons conversant with linotype machines, which, however, differ in detail from one another, the general principle being as above stated.

I come now to Mounsey's application, which, as already said, is for "an improved matrix cleaner." The complete specification begins by saying that "the invention is for the purpose of automatically cleaning the matrices of linotype machines every time they have been used and before they are placed in the magazine, and consists of two pair of brushes, one pair being fixed on to the intermediate elevator channel plate, and another pair being fixed on to the distributor box, in such manner that the matrices in being distributed from each line shall pass the brushes, one of each pair of which will rub against and clean the front side and the other the back side."

The "intermediate elevator channel" referred to is a part of the machine through which the matrices pass, supported by the projecting shoulders as above described, immediately before reaching the place of distribution or distributor box.

The specification describes the means of the attachment of the brushes, which, shortly stated, is as follows: - An oblong slit is eut in the wal) of the channel, through which a brush projects for a small distance into the channel itself, so that the edges of the matrices are rubbed by it in passing, two such brushes being aflixed opposite to each other at the two points mentioned.

The claim is as follows : - " In linotype machines two or more

brushes attached to the intermediate elevator channel plate and H. ©. oF A.

two or more brushes attached to the front and back plate of the ee

distributor box for the purpose of automatically brushing and pryoryer Co.

cleaning both sides of the matrices after they have been used for 1"

forming a line of type and before they are distributed into the Mousey.

magazine, all substantially as described and shown." Griffith C.J. The appellants oppose the grant on the grounds already men-

tioned ; and in support of their opposition rely on a specification,

which was published in Melbourne in February 1900, of an

English patent for "Improvements in Linotype Machines" (called

Lock's Patent) and in which the invention is described as con-

sisting of an automatic cleaning device at which each matrix

must clean the edge that carries its indicating letter, or at least

so much of it as is immediately adjacent to the letter. The mode

of fixing the brush involves nothing not in ordinary use. The

place chosen by Lock for the process in the case of a Mergen-

thaler machine, which the inventor takes as an example, is the

channel through which the matrices pass immediately after

leaving the assembly box and before the cast is taken. But the

specification says : - "The reason why the particular part m of

the whole path through which a matrix passes from the time it

leaves its magazine to the time it is returned thereto is chosen

for such cleaning when the invention is applied to a Mergen-

thaler linotype machine is because each matrix is held during its

passage through the slot m in a convenient position for being

cleaned as and where the invention intends, and also because all

of them are moved along in that position in the direction of the

line of indicating letters y 99. The invention does not limit us

as to where, in the whole path of the matrices, the cleaning shall

be effected, because the invention allows the cleaning device

being brought to bear upon the matrices at any part of that path

which may be suitable for the purpose. The position of that

part in the path may vary according as to whether the machine

is a Mergenthaler or any other linotype machine." The form of brush illustrated is a round one projecting through

a round hole in the wall of the channel, but the specification

says : - "The cleaning device is illustrated as large enough to clean only as much of the matrix edges as is adjacent to the Vou, 1X, 14

indicating letters. his is all that is necessary to keep them legible, but the invention includes the device being large eng to keep the whole edge clean, if desired." 3 The applicant says in his specification that he is aware that single brushes have been fixed on or behind the distributor beam, by which one side only of the matrices can be cleaned, and - disclaims "the sole right of niaking such." Under the English patent law opposition to the grant of a patent on the ground of want of novelty is not allowed. In other countries, eg., the United States of America, novelty isa question _ to be investigated before the grant. The same rule was adopted in Queensland before the establishment of the Commonwealth, and - is adopted in the Commonwealth Patents Act 1903. The reasons for the alteration are sufficiently obvious. See. 56 allows opposi- tion to the grant of a patent on any of six grounds and no others, two of which are (¢) want of novelty, and (jf) prior pub- lication. What is commonly and conveniently called want of - subject-matter is not one of them. " Want of subject-matter" - really means that the alleged invention is not a "manner of ; new manufacture," and involves two questions, whether it is a "manner of manufacture," and whether it is new. An objection - that the alleged invention is for an idea only without any means - specified for giving effect to it would fall under the first head. The objection that it was already in use or had been already patented would fall under the second. Proof of want of novelty - is sufficient to support an objection for want of subject-matter, - but it does not cover the whole ground open under that objection. Both terms have long been in use in patent law. In my opinion the word "novel" in see. 56 (e) is to be read in the sense in which it has always been used in patent law. As applied to the present case it means that the alleged invention is substantially - identical with a process or "manner of manufacture" already known to be public, or, to adopt the words of Sir R. Webster in In ve Todd's Application (1), that the difference is not sufficient to differentiate that which had gone before from that which i 15

invention was not new: Saxby v. Gloucester Waggon Co. (2). () 9R.P.C., 487. (2) 7Q.B.D., 305; 75 LT, Jo., 167.

A rule now firmly established was thus laid down by Lord 3- ©. oF A. Westbury L.C. in Harwood v. Great Northern Railway Co. (1): as, "You cannot have a patent for a well-known mechanical con- [yoryre Co. trivance merely when it is applied in a manner or to a purpose,

which is not quite the same, but is analogous to the manner or Movssey. the purpose in or to which it has been hitherto notoriously used." Grisith c.3. In Gadd vy. Mayor, &e., of Manchester (2), cited in Williamson v. Patterson (3), Lindley L.J. said: - *" A patent for the mere new use of a known contrivance, without any additional ingenuity in overcoming fresh difficulties, is bad, and cannot be supported. If the new use involves no ingenuity, but is in manner and purpose analogous to the old use, although not quite the same, there is no invention. . . . On the other hand, a patent for the new use of a known contrivance is good and can be supported if the new use involves practical difficulties which the patentee has been the first to see and overcome by some ingenuity of his own." Morgan & Co. v. Windover & Co. (4) (in the House of Lords), which was an action for infringement of a patent for affixing C-springs in front of carriages, affords a good illustration of the rule applicable to the issue of novelty. The defendant put in issue the novelty and the utility of the invention, and it appeared that such springs had already been used at the back of carriages. The following passage from Lord Herschell's speech (5) contains a clear exposition of the law applicable to such a case : - " Now, my Lords, if it had required mechanical ingenuity and skill to adapt the composite springs which had heretofore been used in the hind part of a carriage to the front part of a carriage, so that it was not the mere substitution in front in substantially the same way 5 as the substitution had taken place at the back, but that it needed some skill and ingenuity to adapt to the front part of the carriage that which had been applied to the back, I should have thought that there was sufficient subject-matter and that the patent could have stood. But when once it is admitted that all that can be claimed as new is the idea of putting it in the front instead of at the back, and that when once the idea was enter-

tained, any workman told to do it would, without any instructions - or any special mechanical skill, be able at once to do it, it seems to me that that really concludes the case against the respondents, because if their contention be well founded it would certainly be somewhat extensive in its consequences.

"Tt is said that it needed invention to make this substitution, and that this is obvious, because whereas for some period of time - the substitution at the back of the carriage had been known, nobody thought of making the substitution at the front of the carriage, though, when made, people have found out its advan- tages; and a suggestion was made that this really was the attaining an end at which many people had been striving - namely, improving a C-spring carriage so as to do away with the perch. Here, again, I think the same confusion of idea comes in; it was not really the achieving that at which men had been aiming who were seeking to improve the C-spring; it was an act of a different nature altogether. It did not achieve the end at which they were aiming; it was not an adaptation of the C-spring in the sense in which that word is used in relation to _ many of these efforts at all events; it was the applying to a carriage something which possessed some of the advantages which the C-spring had possessed.

"Now, my Lords, if it were held that that was enough to con- stitute a new invention, just consider what consequences would follow. It is common knowledge that when a new mechanical contrivance, such as a new spring (and many other illustrations might be given) is first invented it is often a very considerable time before its advantages are seen and realized. Men are slow to try experiments, however successful they may turn out to be when once tried. But if the argument of the respondents were well founded, then if there was an invention of a new spring, let us say, for railway engines or carriages, and for some years no one had taken advantage of it in a particular part of an engine or carriage in which a spring was used until some one thought he would use it in that place, the first person who used it in that place could take out a patent for so using it and protect himself against all the rest of the world, and acquire a monopoly if it turned out that there were advantages in its use in that particular

place which had not occurred to anyone before. It seems to me, my Lords, that that would be extending the rights which are conferred upon patentees of new inventions beyond anything which preceding cases will justify." It will be seen that the question involved was treated as one of novelty, and not as one of utility.

In the present case, the appellants maintain that Lock's specification substantially describes all that is to be found in Mounsey's alleged invention. The only points of difference are (1) that by the applicant's invention the intaglio of the type upon the matrix is cleaned as well as the indicating letter; (2) that both edges are cleaned at once ; (3) that they are cleaned twice instead of once only; and (4) that the places chosen for the cleaning and the shape of the brush are different. So far as the last points of difference are concerned, they are quite immaterial, since Lock had already told the public that the brushes might be brought to bear upon the matrices at any point of their path, and might be of any suitable shape. here is, therefore, nothing new in the mere selection of a different part of the path from that suggested by him, whether the newly suggested position is for other reasons a better position or not. As to the cleaning of the intaglio edge of the matrix, the case seems to me to be indistinguish- able from Morgan & Co. vy. Windover & Co. (1). The channels through which the matrices pass must necessarily have two sides or walls. The invention made known by Lock's specification was fixing a brush on one wall so as to rub the edge of the matrix as it passed. If any one desired to clean the other edge all he had to do was to put the brush on the other wall of the channel. The idea of brushing both edges does not, of course, constitute a new invention in the sense in which that term is used in patent law. With regard to the idea of brushing both edges at once, it is suggested, in the evidence, that if the brush were brought to bear on the matrices while suspended in the distributing box and were applied to one edge only, the delicate adjustment of the corresponding serrations might be endangered unless a corresponding pressure were brought to bear by another brush on the other edge. This seems to me to be no more than

saying that if the point chosen for the application of the brush is the distributing box, ic. a place presenting particular diffieul- ties which do not occur elsewhere, an additional precaution should be used. I cannot think that this is novel in the sense already

It is not, therefore, necessary in the present case to decide whether the absence of invention or ingenuity, as distinguished - from substantial identity (if it can be distinguished), ean be set - up under an objection of want of novelty. I am strongly disposed to think that it can, at any rate where the absence is manifest, However that may be, the question of substantial identity is one of fact, which I think we are bound to determine for ourselves. ; I think the substantial identity is proved. hat is sufficient to decide this case.

In my opinion, therefore, the opponents have established their objections, and the appeal should be allowed.

O'Coxnor J. I am of opinion that the patent applied for - ought not to be granted. It is not denied that Lock's patent was : made public in Melbourne in the early part of 1900, and that everything disclosed by his specification then became part of the common knowledge respecting linotype machines. The argument turned substantially on two questions. First, whether the appli- cant's invention differs in any real sense from Lock's. Secondly, if it does, whether the difference involved such an exercise of the inventive faculty as is necessary to constitute "a manner of new manufacture " within the meaning of the Patents Act 1903. The appellants objected to the latter question being raised, contend- ing that sub-see. (e) of sec. 56 of the Patents Act 1903 does not empower the Commissioner to determine that issue on an applica- tion for registration. The point is of much importance in the administration of the patent law, and is exceedingly arguable. If _ it were necessary to decide it on this appeal I would require a fuller argument than we have so far heard before coming to a conclusion, But in the view I take of the first question it becomes unnecessary to express any opinion on the objection. I shall, without repeating, adopt the description of the linotype machine and of the common knowledge existing in regard to its

mechanism and use as set forth in the judgment of my learned H. ©: oF A.

brother the Chief Justice, merely adding that in what I have to

say I shall describe the edges of the matrices as the " indicating " Lrxorvrr Co.

edge and the " mould" edge respectively. The essential feature of Lock's invention is the automatic cleaning of the indicating edge of the matrices by means of a brush fixed on the side of the channel through which they pass on their round journey from the magazine back to the distributing box. The brush is placed at any portion of the channel which may be suitable for the purpose, and is so arranged that the indicating edge of each matrix must rub against it in passing. The applicant claims to register an invention which adapts the Lock system of automatic brushing to the cleaning at the same time of both edges of the matrix - the mould edge as well as the indicating edge. This is effected by brushes fixed in pairs opposite one another in the sides of the channel in two places - one or more pairs being attached to the intermediate elevator channel plate, and another or other pairs to the front and back plate of the distributor box. It is admitted that there is nothing new in the form of the brush or the method of attaching it to the plates, nor can it be contended that there is anything substantially new in applying Lock's method of auto- matically brushing one edge of the matrix to the cleaning of the other edge. The applicant in his specification, after disclaiming in substance the sole right of doing anything which could be effected by Lock's invention, states in these words what his own invention amounts to - " my invention having reference to double brushes placed on the intermediate elevator channel plate and on the distributor box of linotype machines." Taking, therefore, the applicant's own description, there are two features only, as it seems to me, in which he claims that his invention has gone beyond Lock's. First, in the use of brushes in pairs facing each other on opposite sides of the channel. Secondly, in selecting the point on the journey of the matrices at which the brushes are to be applied. As to the first, it may be conceded that the cleaning of the mould edge of the matrix is in one sense a different object from the cleaning of the indicating edge, which was the immediate object at which Lock was aiming. But Lock's invention was on the face of it capable of being applied to cleaning either edge or

H.C. or A. both edges, and the applicant's alleged invention, apart from 1909. selecting the portion of the channel for brushing, amounted to no = -

Livoryre Co, More than fixing a duplicate set of brushes on the opposite side -

of the channel. But that differs in no substantial way from

Lock's invention: see Lord Herschell's observations in Morgan

oconmnars, & Co. v. Windover & Co. (1). Whether the mould edge or the indicating edge is to be cleaned, it is the application of Lock's method to one or other or both sides of the channel that effects

the cleaning. There is therefore nothing new in that portion of the applicant's claim. As to the second feature claimed as noyel the same considerations apply. A paragraph in Lock's specifica- tions contains the following passage : - "'The invention does not limit us as to where in the whole path of the matrices the clean- ing shall be effected, because the invention allows the cleaning device to be brought to bear upon the matrices at any part of that path which may be suitable for this purpose." Earlier in the same paragraph the "whole path of the matrices" is explained to be "the whole path through which a matrix passes from the time it leaves its magazine to the time it is returned thereto." Lock might therefore at any time have fixed his brushes at the very points which the applicant's invention has selected. In other words, Lock in his patent had already potentially selected those points for the application of his brushes. There was nothing therefore in the selection of points for attaching the brushes that had not been already discovered and made known by Lock's specification. For these reasons I am of opinion that the applicant's specification does not describe anything which is not to be found in Lock's specification, that his alleged invention adds nothing to the common stock of knowledge respecting lino- types in existence at the date of his application, and that his alleged invention is therefore not novel within the meaning of sec. 56 sub-see. (¢). It follows that the appeal must be allowed, and a declaration made that the patent ought not to be granted.

Isaacs J. The only objection to the grant of the patent is that the invention is not new. 'The stage at which the objection is taken cannot alter its meaning, though it does, in my opinion,

affect the amount and strength of the evidence with which the H.C. or A.

Court may be satisfied. A decision adverse to the applicant is

final, and entirely shuts him out from a possible meritorious claim, Lyyorvre Co.

and this is a serious consideration ; a decision in his favour, on the other hand, is not conclusive, but leaves the question open to further agitation on possibly fuller materials. I adhere to what I said as to this in Moore and Hesketh v. Phillips (1).

But the Court is still bound to see that the ground on which the claimant stands is, at all events, substantial - though it may eventually, on further proceedings, prove to be untenable - and the claim must be reasonable, having regard to all the facts adduced. The applicant asks for a monopoly against the publie, and these proceedings in opposition are intended by the Act as some real protection against creating, even primd facie, a privilege which, on examination, the Court is satisfied ought not to be created.

Now the claim is a monopoly of the right of placing brushes parallel with each other on opposite sides of certain parts of a linotype machine. Lock's patent clearly shows how one brush may be placed at the side of the machine, and at any part of it, that is, any part where a brush may be placed at all. It requires no expert knowledge, and needs no expert evidence, to tell me that Lock's device might be put on either side, and if on either side, on both sides. If the operator observed the matrices to be in need of cleaning on the operative side, it would obviously require no invention to put Lock's brush on that side instead of on the other side, and the applicant's claim does not reach such a case or contest the right so to apply Lock's brush. But, says the applicant : - "I do object to your cleaning both sides, even with Lock's brushes, at the same time. You may put them anywhere you like provided they are not opposite each other: and you may even have them opposite each other, provided you do not put them in the two places I have selected as the places where the last particles of adhering matter may be brushed off."

He says that is novel. Now, the test of novelty is laid down by Lord Hatherley in Cannington v. Nuttall (2) in these terms:

letters patent, effectively obtained by means of your new o. apparatus, whereas it had never before been effectively obtained by any of the separate portions of the apparatus which you have - now combined into one valuable whole for the purpose of - effecting the object you have in view."

The "product" here is the cleaning of the sides of matrices. Has the applicant, by some new apparatus, as a combination suc- ceeded in cleaning the sides of matrices more effectively than conld have been done by Lock's method? It is not a sufficient answer that Lock only referred to one side of the matrix. In the case I put in argument of a man describing how one side of a horse might - be brushed, it would be no new invention to apply what is really the same process to the other side of the animal also.

The law as to this is laid down in Riekmann v. Thierry (1) by - Lord Davey (with whom Lord Muenaghten concurred). Lord - Davey said: - * Now, the law upon this subject, I believe, is all to be found in the case in this House of Hurwood v. Great Northern Railway Co. (2). The proposition there accepted and Jaid down was that 'a mere application of an old contrivance in the ordinary way to an analogous subject, without any novelty in the mode of applying such old contrivance to the new pur- pose, does not make a valid subject-matter of a patent.' The law thus laid down has never since been doubted, though whether it - has always been consistently followed or rightly applied may be open to question. It is not enough that the purpose is new and that there is novelty in the application, so that the article pro- duced is in that sense new, but there must be some novelty in the mode of application. By that I understand, that in adapting the old contrivance to the new purpose, there must be difficulties to be overcome, requiring what is called invention, or there must be some ingenuity in the mode of making the adaptation." And Lord Halsbwry's observations in arguendo (3) are to the same effect.

The respondent answers this by saying that those observations relate entirely to subject-matter as distinct from novelty, and do -

because anticipated. I think an effective reply is afforded by

the case of Arnot v. Dunlop Pneumatic Tyre Co. Ltd. (1). It tiyorver Co.

was an action in the Scottish Courts for infringement of Lenson's

patent. The defendants attacked the validity of the patent, Mousey.

'The articles made under it were a commercial success. The Lord Ordinary held that it was both new and useful, and after dealing with its features said (2): - *This being so, I do not think that much need be said about utility or subject-matter." Then he proceeded to observe : - " As to anticipation, however, there is no doubt something to say." He examined the deserip- tion in Lenson's patent with that in a previous patent - Parnall's

• and arrived at the conclusion that there was no anticipation ; because there was modification of Parnall's patent, and because Parnall's object was different and had no special relation to the particular articles and advantages indicated by Lenson.

On appeal before Lord Dunedin (Lord President) and Lords Adam and Kinnear, the decision was reversed. The learned Judges agreed there was an infringement. "But," said Lord Dunedin (3), "the point on which I am constrained to differ from the Lord Ordinary is the point which arises upon the prior specification of Parnall, because if the prior specification of Parnall really disclosed the so-called invention of Lenson, for which he got his patent, then of course the case must be at an end, because the patent is bad. I am of opinion that the inven- tion, such as it is, was entirely disclosed by the prior specification of Parnall, and that anyone having Parnall's specification before him could construct what I may term the Lenson covering without the addition of any inventive faculty at all."

On appeal to the House of Lords, Lord Loreburn L.C. quoted the latter part of the Lord President's words already mentioned, and said that that put the case in one sentence. He added (4):

• I do not think that the difference, which is a diminutive difference, between the two constitutes ony real invention." Now the three Courts dealt with the question of novelty - that is

(1) 22R.P.C., 105, id., 472; 25R.P.C., (3) 22 R.P.C., 472, at p, 475. 309. (4) 25 B.P.C., 309, at p. 312. (2) 22 R.P.C, 105, at p. 108.

H.C. ov A. anticipation or no anticipation - on the same footing. But the two

we. superior Courts looked at the two specifications to ascertain - whether there was any real invention in the later one which was not already contained in the earlier, and finding there was none, held that the former anticipated the latter entirely, which is only another way of saying the latter contained nothing new. Saxby v. Gloucester. Waggon Co. (1), is to the same effect, where Field J. said with reference to an objection of want of novelty : - *It was admitted by both parties that the question to be decided was one of fact, whether or not the invention specified was such a _ substantial improvement on what had already been known and published as to render it the proper subject of the patent within the rule stated by Lord Westhbwry in Spencer v. Jack (2)."

The respondent's contention is opposed to these cases. The respondent says the purpose is new, the application is new, and the article produced - namely, the cleaning of the matrices - is in that sense new. Lord Davey says that is not sufficient. What is the suggested novelty in the mode of application? Nothing but putting the brushes opposite one another; I put the places selected aside, because Lock's claim covered all suitable places, But putting the brushes opposite is not new in the sense neces- sary for this purpose; it is not new as applied to invention.

The root of the matter, which is altogether one of fact, is this: The apparatus consisting of double brushes placed along the sides of the machine, opposite each other, is an invention undoubtedly, but as an invention is certainly not entirely new. Admittedly some part of that invention is old; brushes are old, the screw is old, affixing a brush to one side is old, the method of attaching and regulating a brush is old, cleaning one side of the matrix is old, and the question, therefore, is how much is old, and how much is new ? - that is, new in the sense used in the Patents Act, because "new" has various meanings. A hat may be called new because it has never been worn, or in another sense because it is of a somewhat uncommon shape, but you could not, for either of those reasons, call it new in a patentable sense.

Mr. Justice Field, speaking for the Supreme Court of the United States, puts the matter very clearly in Lhe Milligan &

(1) 7 Q.B.D., 305, at p. 307. (2) 11 LT. (N.S.), 242.

referred to. He said : - 'A distinction must be observed between Liyorver Co.

render the article new in commerce; as powdered sugar is a different article in commerce from loaf sugar, and ground coffee is a different article in commerce from coffee in the berry. But to render the article new in the sense of the patent law it must be more or less efficacious, or possess new properties by a com- bination with other ingredients; not from a mere change of form produced by a mechanical division. It is only where one of these results follows that the product of the compound can be treated asthe result of invention or discovery, and be regarded as a new and useful article."

Therefore I accept the whole of the combined apparatus described by the applicant as an invention. If he were the first in Australia to devise it, undoubtedly it would be new; but in view of Lock's patent and the common knowledge previously existing, I come to the conclusion clearly and without hesitation that in fact the invention is old. There is no substantial differ- ence between the invention comprised in previously existing knowledge and that comprised in the applicant's invention. The essence of it all is old; its substance was already included within the bounds of public knowledge, and nothing was added to the old device except a mechanical arrangement which not only persons highly versed in the trade would be expected to employ where the necessity called for it, but would be suggested by commonsense to any person acquainted with Lock's mechanism and using the ordinary experience of life. The case falls short of the requirements of a patentable combination (see Moore and Hes- keth v. Phillips (2) ).

As to the general statements in the declaration that inventionand experiment were required for the applicant's device, there are two observations to be made. First the applicant's own statement is open to the reflections of Lord Davey in Riekmann's Case (3);

(1) 97 U.LS., 3, at p. 6. (2) 4C.L.B., 1411, at p. 1426. (3) 14 R.P.C., 105, at p. 122.

and the corroborative witnesses are careful to add qualifyin words, namely, " to apply a pair of brushes as the applicant has. done." But the claim, as learned counsel for the respondent stated, would debar even Lock's device from being used on both sides at the places designated. It was boldly put that Lock - himself would infringe the applicant's patent if he put two of his - brushes opposite each other within the limits selected by the applicant.

I attach very little importance in the circumstances to the so- called expert testimony. It has not condescended on particulars, or explained what is meant by the declarants when they use the - words "experiment " or "inventive skill," and with the materials before us, it appears altogether a matter of common knowledge and commonsense added to Lock's device.

In my opinion, therefore, the objection has been sustained and the appeal should be allowed.

Hiceins J. Mounsey's specification, and the nature of his alleged invention, have been already amply described. What he says, in effect, is that somebody else had already used the device of a single brush to clean the indicator edge of the matrix as it - passes ; but that his claim is for the device of two sets of two brushes, each set at two definite points, to clean not only the indicator edge, but also the edge which contains the mould for - the letters. This statement, from which I exclude all matters in controversy, is sufficient to show that the applicant achieves substantially additional results by substantially additional means, as compared with Lock and Gardner - on whose British specifica- tion deposited in the Australian Patents Office, but not subject of a patent grant here, the opponent company relies. It was not denied in argument that the double brushing process, on both - edges of the matrix, involves a clear addition in fact to the single brush device. But it was contended strongly that the ; quadrupling of the brushes in the manner described does not involve suflicient inventiveness on the part of the applicant to justify the grant of letters patent for the sole right to make, use, exercise and vend this additional device.

Now, the objection as stated, and as allowed by the Act, is

that the applicant's " invention is not novel." The first question, to my mind, is - is it open to the opponents under this objection to urge that the applicant has not shown sufficient inventiveness in his additional device. It is admitted that want of inventive- ness could be taken as a defence to an action under another plea

• shortly called "want of subject-matter." The form of the objection allowed by sec. 56 (¢), is "that the invention is not novel"; but according to sec. 4 ("invention") the word " inven- tion" includes an alleged invention; so that the objection should be read : - " That the alleged invention is not novel." It means : - " Even if what you allege to be an invention is an invention - even if it shows sufficient inventiveness - it is not new : some one else discovered it before, and made it available." It follows that, so far as the form of this objection is concerned, the Court has not to go into the truth of the allegation that the added matter is an invention - a true invention involving suffi- cient inventiveness - and has merely to consider, is the added matter (if any) new - has it been used or known before ?

Under our law, a grant of letters patent is no guarantee to the holder of the grant that he has patent rights, that he has a property which he can assert against the world. If, after he obtains the grant, he bring an action for infringement, the defendant may plead that "the invention is not new," that "the invention is not useful, that the invention is not one for which letters patent could by law be granted," or that "the plaintiff is not the true and first inventor" (see Bullen and Leake, 4th ed., p. 448). These defences are quite distinct, logically and in practice, although it often occurs that the same facts are used to support more than one of these defences, and from the nature of the patent cases some confusion of expression has therefore often crept into arguments, and even into judgments. But, inas- much as our Act, sec. 56, allows objection on any of six definite grounds "but on no other,' it becomes necessary for us to keep steadily to the accurate meaning of "not novel." The meaning of "not novel" may be taken to be the same as in an action for infringement. The meaning certainly is not wider.

No doubt the reason that Parliament has not allowed defences of "not useful," or "not one for which letters patent could by

law be granted," or "not the true and first inventor," to be raised at this stage, is to prevent the machinery of the Patents Office and of the Courts from being blocked by inquiries of the most delicate and difficult character, made on such unsafe materials as mere statutory declarations, instead of full vird vdce evidence with cross-examination - inquiries which, when the patent is granted, give no finality as to rights. The object of objections at this stage is to prevent grants from being made which are obviously and hopelessly bad, and which put the public to expense and annoyance. In England, under the Act of 1883, there are only two kinds of objections allowed to be taken; in Australia there are six. In England even the objection of want of novelty is treated as being too delicate to be taken in this crude fashion ; but in Australia it has been allowed. More- over, our duty now is not to decide whether the patent will hold good or not, but "whether the grant ought or ought not to be made" (sec. 59). It is one thing to refuse a grant, for what it may be worth; and quite another thing to declare the grant invalid after it has gone through the ordeal of an action for infringement. When a patent is refused, the applicant never gets afterwards the opportunity of fully testing his right; and therefore the practice of the Courts has always been to lean in favour of the grant, and not to interfere with the Registrar granting a patent (as here), unless he is clearly and indubitably wrong (see T'olson's Patent (1) ).

Does, then, the objection "that the alleged invention is not novel" involve the objection that "the invention is not one for which letters patent could by law be granted?" This latter objection is usually called, for brevity, an objection for want of subject-matter. In England, as I have said, an objection for general want of novelty is not allowed; but an objection is allowed to the same effect as our sec. 56 (c), that the invention has been patented on an application of prior date. There was an application made to Sir Richard Webster A.-G., for a patent for stoppering bottles, In re Todd's Application (2), and he decided against the applicant on this ground of a prior patent. He admitted that it is only "in the clearest possible case that a

patent ought to be stopped ;" but he found the mode of attaching H. ©. or A.

the cork to the capsule was in each case identical. And he used

these words - words which come with great weight from one of tyyorver Co.

the most eminent authorities on patents as counsel, as Law Officer, as Master of the Rolls (1): - *JI have not to deal with subject-matter properly so called; that is to say, supposing Todd's invention to have been the first invention brought before me, it would not matter whether it showed no subject-matter, if it was a claim to that which had not been done before; 1 quite agree Ihave not to consider whether it is subject-matter or not. But when there is a previous anticipatory patent it is necessary to consider then indirectly the differences, and without saying whether those differences form subject-matter or not, to decide whether the differences are sufficient to differentiate that which has gone before from that which is now claimed." So here, the question is, is there a substantial margin in fact between Lock and Gardner's device and the applicant's ; and if there is, there is novelty, whether the novelty shows sufficient inventiveness or not. The same ground was taken by Sir John Rigby S.G. in In re Boult's Application (2); and Sir Robert Finlay S.G. in In re Wylie and Morton's Application (3). But in the case last mentioned, we have a good instance of the double use of the word "invention" - either a device properly patentable, or a device alleged to be patentable. In a previous patent, Gatty had specified for a dyeing process soluble salts of chromium and soluble salts of iron. The applicants claimed bisulphite of chromium (which is a soluble salt of chromium) and bisulphite of iron (which is a soluble salt of iron). The applicants had added nothing, whether showing inventiveness or not; and it was held, therefore, that the patent should be refused. Sir Robert Finlay S.G. said (4) : - * I am not satisfied that the applicants have shown any invention with reference to the process which they propose to use." The meaning in this case is obvious; for there was nothing additional at all. There was no "invention," for there was nothing more than in the prior patent. The same explana-

tion applies to In re Hedges' Application (5). One point was

found in an opponent's patent; another was in daily use: " When : those parts are struck out nothing remains which, to my mind can properly form the subject-matter for a patent." ' The case of Saxby v. Gloucester Waggon Co. (1), is at first - sight inconsistent. The plaintiff brought an action for infringe- : ment of his patent of 1874 for interlocking apparatus in railway a points and signals. But, under a plea of want of novelty, it was proved before a referee that every element of the patent was to be found in previous patents of 1870 and 1871, and there was no new result. The two alleged inventions were substantially _ identical in fact. This would be conclusive against the plaintiff, even without a plea of "not sutlicient subject-matter for a patent." But counsel for the plaintiff urged that his invention, as it combined the previous patents, was such a substantial im- provement on what had been already known as to render it the proper subject of a patent. The Court of Queen's Bench, speak- ing through Field J., held against the plaintiff, and diseussed the want of inventiveness as if it came under the defence of want of novelty. But the learned Judge was careful to point out that - both parties admitted "that the question to be decided was one of fact, whether or not the invention specified was such a substantial improvement on what had already been known and published as to render it the proper subject of a patent" (2). This admission, such as it is, goes no further than the plaintiff's counsel's view of expediency in a particular case, where want of inventiveness appeared under another plea,and would be as dangerous if taken thereunder as under the plea of want of novelty. Pleadings are merely means to an end; and in this case the parties and the Court were content to discuss the point as to inventiveness under the plea as to novelty. Moreover, nothing is more natural than to confuse in ordinary talk novelty in inventiveness with novelty in actual manufacture ("new manufactures," within the Statute of James I.); and yet the latter is the meaning of "novel" in the plea of not novel. his appears more clearly in the earlier cases when issues were more precise than they are now. In Walton v. Potter (3), it was held that, under the plea of want of

(1) 7 Q.B.D., 305. (2) 7 Q.B.D., 305, at p. 307. (3) 1 Web. Pat. Rep., 597, at p. 601.

novelty, the defendant could not be allowed to show that the H. 0. oF 4.

invention was one for which in point of law a patent should

not be granted. And the converse holds good - under a pyyoryrz Co.

plea that the alleged invention is not a matter for which

letters patent could be granted, it is laid down that such a plea Movysey.

does not put in issue novelty: Booth v. Kennard (1). These cases are treated as still being law in the last edition of Frost on Patents (1906, 3rd ed., vol. 1., pp. 403, 404), and in Hdmonds on Patents (1897, 2nd ed., p. 389). The point was left in doubt by Ridley J. in Electrolytic Plating Apparatus Co. v. Holland (2); but the authorities were not cited, and the point was unnecessary for the decision. In Spencer v. Jack (3), the Lords Justices, in sending issues to a jury in a patent suit, deliberately separated the issues: - (1) Whether the plaintiff's invention constituted a new manufacture, and (2) whether it constituted a new inven- tion: see the same case after issues found (4). Except Saxby vy. Gloucester Waggon Co. (5), no case has been cited to us in which want of inventiveness has been treated as coming under the plea of want of novelty; and that case, as I have shown, turned on an express admission made by counsel, under special circumstances, for the purposes of that case only. All the cases in which the Court has decided against the patentee on the ground of want of inventiveness have been actions of infringement, in which the plea of want of sub- ject-matter has been pleaded as well as the plea of want of novelty. Such was the case in Morgan & Co.v. Windover & Co. (6).

Such again was the position in the recent case of Arnot v. Dunlop Pneumatic Tyre Co. (7). In an action for infringement of a patent for driving aprons, the Lord Ordinary found that the plaintiff's invention "had sufficient merit, if new, to make it patentable" (8). It was new, if not anticipated by Parnall's patent; and the Lord Ordinary held that there was no anticipa- tion, and granted an interdict. On appeal to the Inner House, however, it was held that there was anticipation - that Parnall's

patent in fact contained all that was described in the plaintiff's patent - and something more - an "underneath platform" - material underneath the soles of the feet. This decision was affirmed by the House of Lords. The case turned wholly on the - facts. There was no argument as to the distinction between % want of novelty and want of subject-matter, for the case turned wholly on anticipation, not on ordinary want of novelty. There was no overruling of the previous cases to which I have referred, - or even reference to them. If the question of inventiveness could _ not be discussed under the plea of anticipation, it could have been discussed under the other plea of want of subject-matter, so that - there was no use in arguing as to the precise scope of each plea. The only thing which gives the case any importance for present purposes is a form of expression used by the Inner House ina sentence which was approved by the House of Lords - that the - plaintiff 's invention " was entirely disclosed by the prior specifica- tion of Parnall, and that anyone having Parnall's specification - before him could construct what I may term the Lenson cover- ing without the addition of any inventive faculty at all" (1).

This last phrase is not felicitous in any aspect. I presume that the meaning is "without the addition of anything the result of inventive faculty " or " without the use of any further inventive- ness." Why, it is asked, does the learned Judge refer to inventive faculty if the objection of " prior patent" does not include want of inventive faculty ? The question assumes that, if the objection of prior patent involves the question of inventiveness, the plea of mere want of novelty involves it also - which is by no means clear. But whether this assumption is correct or not, it is clear that the attention of the Court was not directed to the difference between the two issues of prior patent and want of subject- matter, both having been pleaded ; and that in using the phrase in question the Court did not mean to lay down any principle, or - to decide anything except this - that the plaintiff's invention had nothing new in it - that the plaintiff had invented nothing new - using the word " invented" in its secondary and broader sense.

Moreover the expressions of the Law Lords in Rickmann v. Thierry (2) put the matter beyond all doubt, to my mind. The

Shand dissenting, held, in an action for infringement, that there

_ patent was for an eyelet for boots. The House of Lords, Lord H. ©. or A.

was not sufficient inventiveness to constitute the subject-matter Liyorver Co.

ofa patent. Lord Halsbury L.C. assumed that the article was "novel" (1); yet "a thing may be new, but unless it has some invention it is not patentable." Even Lord Shand distinguished between the objection for want of novelty and the objection for want of ingenuity (2). Lord Davey also distinguished between new and patentable - the thing may be new and yet not proper subject-matter for a patent ; and Lord Davey's words are adopted "in every particular" by Lord Macnaghten (3). Lord Davey says (4): "If the learned counsel meant only that a new and useful article, in the production of which there is invention, is the proper subject of a patent, I suppose nobody will disagree with him. But if he means that an article which is new in the market is therefore proper subject-matter for a patent, irrespective of the question whether the production of it was the result of invention, I do not agree, and I am of opinion that it is not the law." See also per Bowen LJ. in American Braided Wire Co. v. Thomson & Oo. (5); and per Lord Herschell in the House of Lords in Thomson v. American Braided Wire Co. (6). I take, therefore, the true meaning of the plea of want of novelty in a action for infringement from those cases never overruled. I can- not bring myself to think that the same objection - want of inventiveness - may now be taken under either of two separate pleas - not novel, and no sufficient subject-matter. I think that the old rule has uot been changed - the rule as laid down in so many cases of high authority. The point becomes of consider-

able practical importance in this Court, in view of the marked

increase in applications and of the prolonged discussions, in connec- tion with the registration of patents and other such preliminary skirmishes, on mere statutory declarations. In my opinion Parliament never intended that questions as to the fact or the amount of inventiveness shonld be determined in this unsatis- factory fashion. Of course, if, as is now suggested, there is in the

H.C. or A. applicant's patent no addition in fact to the single brush devi 1909.

if the applicant's alleged invention is substantially identical wit . that of Lock and Gardner - there is an end of the matter, there is no difference in fact, there can be no novelty. But such a position is, to my mind, simply unthinkable, when I regard the Higginsy. Single brush for the indicator edges, placed anywhere in tl course of the matrix, in the earlier specification, and the doub! sets of brushes, four in all, placed at two definite points to bi the edge that has the mould for the letters as well as the indi- | eator edge. For the reasons stated, I think that the appeal shoul be dismissed.
