explaining where the applied prior art suggests to one of
ordinary skill in the art a modification of the method of
Uesugi. In this regard, Uesugi is concerned with forming an
aluminum lithographic printing plate support, the admitted
prior art describes a batch process
technique for treating copper and copper alloy plates to form
a lead-frame and Fujikawa is directed to improving a photo-
sensitive polyamide printing plate as outlined above. The
examiner simply has not furnished a convincing line of
reasoning or otherwise explained why the applied combined
teachings of the references would have led one of ordinary
skill in the art to modify the process of forming an aluminum
lithographic printing plate support as taught by Uesugi based
on the specific teachings of those references.
It is significant that the examiner has not fairly
addressed appellants' argument that one of ordinary skill in
the art would not have been led to use a material such as the
copper or copper alloy of the admitted prior art process in
the lithographic printing plate support of Uesugi given the
alleged differences between the semiconductor pellet fixing
lead-frame material that was being addressed by the admitted
