Dear David,
Thank you for your email below.
When considering the question of whether a piece of prior art invalidates a particular claim of the subject patent, my understanding is that the starting point should be to take the features of the subject claim, and look into the prior art to see if anything in the prior art teaches the person skilled in the art these features. If the features are present in the prior art, then the subject claim is not novel. If the features are not present, but a person skilled in the art could still easily arrive at the subject invention (ie obvious), the subject claim is not inventive. This appears to be the reverse of the approach taken in your slides.
With respect to novelty, sometimes the Court also looks at the argument of “reverse infringement”, that is to say, one first construes the features of a particular claim of the subject patent and then having done that, considers whether the prior art infringes this claim. If it does, then the prior art anticipates the subject claim.
At the moment, the purpose and role played by sensors C8-C10 in the train patent is discussed in Q&A60 (ii), but instead of packaging them as a “third detecting unit” which is present in the train patent (and absent from the ‘862 Patent), we have said that C8-C10 cannot fulfil the purpose of the second detecting unit in the ‘862 Patent with respect to sensing the shape and size of the driver cab in order to determine which part of the truck to dodge. In order to change how C8-C10 operates (measuring wheelbase) to being able to detect shape and size of the driver cab, a lot of research and experimentation would need to be carried out.
Perhaps we could say clearly at the start of Q&A60 (ii) that the ‘862 Patent requires a set of sensors to detect shape and size of the driver cab, and this is clearly absent from the train patent. The inventor would have had to design a “third detecting unit” and incorporate that into the train patent. Then, we could go on to say, looking at the train patent, there is this other set of detecting units that the 3rd party’s expert has not dealt with – C8-C10. In the train patent, they serve the purpose of detecting which train cars to scan and which ones to dodge. Even if we treat C8-C10 as the “third detecting unit”, there is still a lot of work to be done to bring it from simple wheelbase measuring devices to sophisticated shape and size detecting units.
Would this work?
As for the “fourth detecting unit” comprising C1 and C11, could you please take me through your arguments? I am not quite sure I got them.
Best regards,
Pei Yee
