The nature of the amendments and their importance to SARB
10 For present purposes, it is sufficient to set out the proposed lack of entitlement plea in relation to the 110 Patent. In terms of VMS's submissions, the proposed lack of entitlement plea in relation to the 924 Patent is in similar terms. The proposed lack of entitlement plea in relation to the 110 Patent is in the following terms:
12 If, which the First Respondent denies, the claims of the First Patent are to a patentable invention, the patentee is not entitled to the First Patent because it does not derive title from Mr Peter Crowhurst who was the or alternatively an inventor of the First Patent and it is just and equitable to revoke the First Patent pursuant to s 138(3)(a) of the Act.
PARTICULARS
(a) The named inventor, Fraser John Welch, did not invent a method performed by a subterraneous detection apparatus for identifying overstay of a vehicle in a parking space comprising the steps of: detecting presence of a vehicle in the parking space; processing and storing data relating to presence of the vehicle in the parking space; determining whether the vehicle has overstayed a defined time duration in the parking space; and wirelessly transmitting data relating to identified instances of overstay of the vehicle in the parking space (the first claimed method), because Mr Welch did not develop a subterraneous detection apparatus which was capable of wirelessly transmitting data relating to identified instances of overstay of a vehicle in a parking space. The first claimed method was invented by Peter Crowhurst, who was not an employee of the patentee, and who did not assign the invention to the patentee.
(b) In the alternative, Peter Crowhurst is a co-inventor of the first claimed method.
(c) The named inventor, Fraser John Welch, did not invent a battery-powered apparatus for subterraneous installation for identifying overstay of a vehicle in a parking space comprising: a detector adapted to detect presence of a vehicle in the parking space; a processor coupled to the detector which is adapted to process and store data received from the detector and to determine whether the vehicle has overstayed a defined time duration in the parking space; a radio receiver coupled to the processor for receiving wake-up signals; and a radio transmitter coupled to the processor for transmitting data relating to identified instances of overstay of the vehicle in the parking space (the first claimed apparatus), because Mr Welch did not contribute the idea of a battery-powered apparatus with a radio receiver coupled to a processor for receiving wake-up signals and Mr Welch did not develop a radio transmitter which was capable of transmitting data relating to identified instances of overstay. The first claimed apparatus was invented by Peter Crowhurst, who was not an employee of the patentee, and who did not assign the invention to the patentee.
(d) In the alternative, Peter Crowhurst is a co-inventor of the first claimed apparatus.
(e) The named inventor, Fraser John Welch, did not invent a system for identifying overstay of vehicles in parking spaces comprising: (a) a plurality of battery-powered detection apparatuses for identifying overstay of vehicles in respective parking spaces when subterraneously installed; and (b) a data collection apparatus for wirelessly retrieving data from the plurality of battery-powered detection apparatuses comprising: a radio transmitter for transmitting wake-up signals to ones of the plurality of battery-powered detection apparatuses; a radio receiver for receiving data from woken-up ones of the plurality of battery-powered detection apparatuses; a memory unit for storing data and instructions to be performed by a processing unit; and a processing unit coupled to the radio transmitter, radio receiver and memory unit, the processing unit programmed to process the data received via the radio receiver and to indicate incidences of vehicle overstay to an operator, where the data relates to identified instances of vehicle overstay in a respective parking space (the first claimed system), because Mr Welch did not contribute the idea of a data collection apparatus comprising a radio transmitter for transmitting wake-up signals. The first claimed system was invented by Peter Crowhurst, who was not an employee of the patentee, and who did not assign the invention to the patentee.
(f) In the alternative Peter Crowhurst is a co-inventor of the first claimed system.
(g) The named inventor, Fraser John Welch, did not invent a method performed by a subterraneous detection apparatus for identifying overstay of a vehicle in a parking space, substantially as described in the First Patent with reference to an embodiment shown in the accompanying drawings (the second claimed method), because Mr Welch did not contribute the idea of a battery-powered apparatus with a radio receiver coupled to a processor for receiving wake-up signals and Mr Welch did not develop a radio transmitter which was capable of transmitting data relating to identified instances of overstay. The second claimed method was invented by Peter Crowhurst, who was not an employee of the patentee, and who did not assign the invention to the patentee.
(h) In the alternative Peter Crowhurst is a co-inventor of the second claimed method.
(i) The named inventor, Fraser John Welch, did not invent a battery-powered apparatus for subterraneous installation for identifying overstay of a vehicle in a parking space, said apparatus substantially as described in the First Patent with reference to an embodiment shown in the accompanying drawings (the second claimed apparatus) because Mr Welch did not contribute the idea of a battery-powered apparatus with a radio receiver coupled to a processor for receiving wake-up signals and Mr Welch did not develop a radio transmitter which was capable of transmitting data relating to identified instances of overstay. The second claimed apparatus was invented by Peter Crowhurst, who was not an employee of the patentee, and who did not assign the invention to the patentee.
(j) In the alternative Peter Crowhurst is a co-inventor of the second claimed apparatus.
(k) The named inventor, Fraser John Welch, did not invent a system for identifying overstay of vehicles in parking spaces, said system substantially as described in the First Patent with reference to an embodiment shown in the accompanying drawings (the second claimed system), because Mr Welch did not contribute the idea of a battery-powered apparatus with a radio receiver coupled to a processor for receiving wake-up signals and Mr Welch did not develop a radio transmitter which was capable of transmitting data relating to identified instances of overstay. The second claimed system was invented by Peter Crowhurst, who was not an employee of the patentee, and who did not assign the invention to the patentee.
(l) In the alternative Peter Crowhurst is a co-inventor of the second claimed system.
11 SARB submits that its proposed plea of a lack of entitlement in relation to each patent is plainly arguable in light of the evidence of Mr Peter Crowhurst and furthermore, that the issues of fact raised by the proposed plea are already raised by the existing plea of insufficiency.
12 Mr Crowhurst has received or been awarded certificates and degrees in the fields of electronic engineering, science (applied physics) and science (mathematics). He is a member of the Institute of Electrical and Electronic Engineers and he holds approximately 12 patents in electronic wireless communications associated with low power transponders and security access systems. He has substantial experience working in the field of radio frequency communications. The bulk of his work has been in the field of short range low power wireless communications.
13 Mr Crowhurst carried out work with Mr Welch in relation to a parking overstay detection system in approximately 2001. As I have said, Mr Welch is the inventor named in VMS's two patents. Mr Crowhurst's involvement with Mr Welch involved the performance of design or consulting services.
14 A subpoena was issued requiring Mr Crowhurst's attendance at Court on 25 November 2020. He attended and was orally examined by SARB. The circumstances in which that came about are described later in these reasons (at [40]-[48]). A transcript of Mr Crowhurst's oral examination was prepared. Mr Crowhurst also produced 11 documents and each of these documents was marked for identification.
15 In the proposed lack of entitlement plea, SARB alleges that Mr Crowhurst was the, or an, inventor of the invention described in each patent or a co-inventor of the invention. SARB submits that Mr Crowhurst's evidence is "crucial" to the lack of entitlement plea.
16 SARB submits that Mr Crowhurst's evidence is also relevant to its pleas of invalidity on the grounds of insufficiency and lack of best method. In other words, SARB submits that the work done by Mr Crowhurst shows that each specification does not describe the invention fully in that "it does not provide sufficient information to enable the person skilled in the relevant art to perform the alleged invention within each claim without new inventions or additions or prolonged study of matters presenting initial difficulty" by reason of one or more of the matters pleaded and the specification does not include "the best method known to the cross-respondent of performing the invention" by reason of one or more of the matters pleaded.
17 SARB submits that Mr Crowhurst gave evidence to the effect that Mr Welch was not able to produce a working embodiment of the claimed invention and Mr Crowhurst performed complex, detailed and innovative work to enable VMS to produce a working embodiment of the claimed invention. VMS's failure to disclose sufficient information in the specifications related to this work, or the specific details of the working system in existence at the date of the filing of the patents, supports SARB's existing grounds of invalidity. As I understand it, SARB's argument is that Mr Crowhurst's work involved inventive effort without which VMS could not make the invention work. That work is not described in the specifications. The precise extent to which the facts and issues relevant to the existing pleas of insufficiency and lack of best method and the facts and issues relevant to the proposed plea of a lack of entitlement overlap will only be made clear at trial. At this stage, it may be said that they appear to overlap and Mr Crowhurst's evidence appears to be relevant to both.
18 VMS contends that leave to amend to raise the lack of entitlement plea should not be granted because the plea lacks proper particulars, Mr Crowhurst's evidence lacks clarity as to the nature or extent of his contribution (if any) to the invention and the case on the facts before the Court is such a weak one that I should be satisfied that the Court would not revoke the patents.
19 Before addressing these arguments, the following matters, which are not in dispute, should be noted.
20 First, SARB has indicated to VMS that it will not seek to file any further evidence with respect to the proposed lack of entitlement plea other than parts of the transcript of the oral examination of Mr Crowhurst and certain documents produced by Mr Crowhurst.
21 Secondly, the issue of inventorship involves two inquiries. First, the court must determine the nature of the inventive concept of the patent in issue. That task raises an issue of construction of the patent specification. VMS cited two authorities in connection with how the issue of inventorship is determined by the court. The issue involves a two part inquiry and the starting point is to analyse the inventive concept of the patent applications. It is then necessary to analyse whether the alleged inventor or co-inventor made a contribution that had a material effect on the inventive concept (Kafataris v Davis [2016] FCAFC 134 at [62]). The determination of the issue of inventorship is not resolved by an assessment of quantitative contributions. Rather, an assessment must be made of the qualitative contributions to the invention. As the Full Court of this Court said in Polwood Pty Ltd v Foxworth Pty Ltd [2008] FCAFC 9; (2008) 165 FCR 527 (at [33]), the issue of what constitutes the invention is determined by reference to the patent specification, including the claims and in some cases evidence can assist. The Full Court went on to say:
… In some cases, the reduction of a concept to a working apparatus by a person may not be part of the invention, in other cases it may be. For example, the construction of an apparatus may involve no more than carrying out the instructions in the specification. This would not normally entitle that person to joint inventorship. On the other hand joint inventorship may arise where the invention is in the apparatus itself, or where the person constructing the apparatus contributed to a different or better working of it which is then described and claimed.
22 VMS submits that the proposed entitlement evidence does not provide clarity as to the nature or extent of Mr Crowhurst's contribution to the invention and that SARB's case in this regard is not apparent from either its proposed pleading of lack of entitlement or from the evidence.
23 VMS also points to the fact that there is no evidence before the Court that Mr Crowhurst raised the issue of entitlement before his oral examination, or that he would now dispute VMS's ownership of the patents.
24 VMS points to a Share Subscription Agreement made on 23 December 2003 between VMS, Mr Welch, a company called Tencap Pty Ltd, Saxon John Hill and Mr Crowhurst and the fact that the Technology is defined in the agreement as:
… The parking restriction enforcement invention known as the Period Longer Detection System invented solely by Welch.
(Emphasis added.)
25 In addition, in a Confidential Disclosure Deed, which is a schedule to the Share Subscription Agreement, and executed by Tencap Pty Ltd and Mr Crowhurst, Mr Crowhurst agrees not to assert rights of any nature in respect of any of the Confidential Information. The definition of Confidential Information includes "all oral and written information relating to the Invention or any other intellectual property, technology, business or affairs of Tencap, VMS or Mr Welch, whether provided in tangible form, by electronic media, by visual display or orally, disclosed to the Recipient".
26 In the attachment to the Confidential Disclosure Deed, there is a description of the system comprising the Invention, namely, the "Period Longer Detection System (PLDS) Invention". The description is as follows:
The Period Longer Detection System (PLDS) is a replacement for the archaistic 'chalking' system upon which local governments in Australia (and elsewhere) rely to ascertain a motor vehicle's compliance with a time limited parking restriction. PLDS is capable of determining the time duration to which a particular vehicle has remained in a specific parking location or bay by means of one or more sensor devices. The duration information relating to a plurality of parking locations are conveyed to a central location which may be fixed or mobile in nature. The received duration information is processed at the central location to determine whether one or more of the parked vehicles are in violation of an applicable time limit. Detected violations result in generation of an alert for purposes of enforcement.
27 VMS also relies on the fact that even if SARB establishes that Mr Crowhurst was the, or an, inventor, or a co-inventor, an order for revocation will not be made "unless the court is satisfied that, in all the circumstances, it is just and equitable to do so" (Patents Act 1990 (Cth) s 138(4)). Subsection 138(4) and s 22A were introduced into the Patents Act by the Intellectual Property Laws Amendment (Raising the Bar) Act 2012 (Cth). Section 22A provides that a patent is not invalid merely because the patent, or a share in the patent, was granted to a person who was not entitled to it, or the patent, or a share in the patent, was not granted to a person who was entitled to it. The relevant transitional provision means that ss 22A and 138 apply in their form as at the date on which the application for a revocation order is made (see AstraZeneca AB v Apotex Pty Ltd [2014] FCAFC 99; (2014) 226 FCR 324 at [182]֪-[184]). VMS submits that there are no particulars in support of SARB's assertion that it would be just and equitable to revoke the patents and, furthermore, such an order would not be made in circumstances in which, on the facts, Mr Crowhurst has acknowledged Mr Welch to be the true and sole inventor of the invention.
28 I do not consider the proposed plea of a lack of entitlement to be inadequate. In each paragraph of the Particulars, the steps or aspects of the method, apparatus or system are identified and that step or aspect invented by Mr Crowhurst rather than Mr Welch is identified. It is true that there are no separate particulars directed to whether it would be just and equitable to revoke the patent even if a lack of entitlement is established, but that means that SARB will be restricted to such relevant matters as emerge from the evidence in the case.
29 The evidence of Mr Crowhurst's acknowledgement of Mr Welch as the inventor of the invention appears to be substantial, but ultimately the issue is one of fact and law for determination at the trial.
30 In my opinion, the proposed lack of entitlement plea is arguable.
31 VMS submits that the fact that SARB has pleaded a number of other grounds of invalidity is a reason not to grant leave to make the amendment on the basis that it is less significant to refuse leave to amend where there are other grounds of invalidity which can be pursued. I am not able to make any assessment of the strength of the grounds of invalidity on this application. In my opinion, if this factor is relevant, it is of minimal significance.
