Consideration - deferred priority date
32 The only use or function of a joystick that the PCT application described was on the rear, or lateral or side of the device, or of a joystick that either moved along the device's body or was protected with or replaced a cover. The PCT application contained no description of a joystick on the front side of the device in any arrangement, or any functionality for the placement of a joystick there. The PCT application always described a joystick as being in a particular location (as opposed to describing one as able to be located anywhere) on the electronic device.
33 The essential description of the arrangement in the complete specification for the PCT application (at p 1.10), excluding claims 1 to 9, is of "a user friendly arrangement of a touchpad or joystick in an electronic device" to enable the user to utilise that touchpad or joystick, as so arranged, in various specifically described locations, all of which the PCT application described in positions other than on the front of the device.
34 The PCT application stated (at p 2.10) that the "above mentioned technical result is achieved as follows" and then described in consistory clauses for claims 1 to 9 (inclusive), the same elements, again, without disclosure of any necessary function, in the described arrangement, that involved a joystick located on the front side of the device. The PCT application stated that the first invention (p 4.10) "may be applied for [sic] a user friendly arrangement of a touch pad and/or touch screen display and/or a joystick in electronic devices" (emphasis added).
35 Thus, a joystick was not an essential integer of the invention of the arrangement as described in the PCT application, except when it was located at positions other than the front of the device. Hence, claim 1 in the PCT application began with a description of the role of each of the three elements, or possible elements, in an arrangement by using the disjunctive "or" between "touch screen" and "joystick". That form of expression had the function, read in light of the complete specification as a whole, of limiting the use of those elements, so far as they described the location of a joystick in the arrangement, to a location described in the relevant particularised applications that included a joystick given in claim 1.
36 In my opinion, the proper construction of claim 1 of the PCT application, reading the complete specification as a whole is that, so far as the joystick had importance or significance in the claimed invention consisting of an arrangement, the actual location of the joystick at a specified position (other than the front of the device) or on a cover constituted its essential place in the claimed invention.
37 In other words, a person skilled in the art, reading the complete specification as a whole, as well as claims 1 to 9 in the PCT application separately, would understand claims 1 to 9 to be limiting the invention to require that any joystick that was to be included as part of the arrangement claimed, would be in a specific location, usually somewhere other than on the front of the device or on a cover. A person skilled in the art (and, indeed, the ordinary reasonable person), reading the PCT application as a whole, would have understood the multiple references, in the complete specification, and claims 1 to 9, to a joystick located on the rear, lateral or side of the device or on a cover or made so as to move along the device's body to signify that the joystick had a role in the invention elsewhere than simply on the front of the device.
38 The natural and ordinary meaning of the complete specification of the PCT application, describes an invention comprising arrangements of three elements, being a touchpad, a touch screen display and, where it included one, a joystick that was described as being in particular configurations and locations. The disclosure of the invention in the specification concerning the possible locations of a joystick was set out before the claims for a monopoly. Throughout the part of the complete specification of the PCT application that preceded the claims, wherever it described the joystick being used in the arrangements comprising the invention, it did so in terms that, relevantly, required the joystick to be deployed on a cover or on locations other than the front of the device.
39 I am of opinion that the natural and ordinary meaning of the complete specification of the PCT application, as filed, is that the arrangements the subject of the claims were limited to uses of the joystick in specified locations other than the front of the device or on a cover, so that an unlimited or unqualified use of a joystick on the front of the device (or at any location) was not the subject of any disclosure to support (or base) a claim for a monopoly for such a use: Welch Perrin & Co Pty Limited v Worrel (1961) 106 CLR 588 at 609-610 per Dixon CJ, Kitto and Windeyer JJ. Nor do any of claims 1 to 9 in the PCT application refer to any use of a joystick on the front of the device or dissociated from a specific location, such as a cover.
40 It follows that the sole claim in the patent in suit travels beyond matter that was disclosed in the complete specification as filed with the PCT application. That is because the claim permits a joystick to be used, without any limitation, at any place on the electronic device, the subject of the claimed arrangement, including the front. In contrast, the complete specification as filed with the PCT application attributed the uniqueness of the claimed invention of an arrangement to one in which, when a joystick was employed, that integer would be used in specified locations other than on the front of the electronic device or used on a cover.
41 It follows that none of the claims of infringement of the patent in the statement of claim would have any reasonable prospect of succeeding. That is because the complete specification in the patent in suit discloses matter (being that a joystick can be located anywhere, including on the front of a device without being on a cover) that was not disclosed in the PCT application as filed. As a result, the sole claim in the patent must have a deferred priority date of 11 July 2014. That claim extended the scope of the monopoly beyond matter disclosed in the complete specification of the PCT application as filed (see s 102(1)(a) of the Patents Act).
