Appeal 2007-2783 Reexamination 90/005,509 Patent 5,533,499 mentions no “adhesion problem” between the flexible strip and any resilient member and also mentions no solution achieved by constructing the resilient member from plastic. Secondly, what we have is only attorney argument and there is no real evidence, e.g., declaration testimony, establishing that there indeed is an “adhesion problem” unless the dilator is made of plastic. Third, the patentee expressly acknowledges that the so called “adhesion problem” does not exist in Iriarte’s disclosed embodiment, and thus it is not of relevance in considering whether one with ordinary skill in the art would know to construct Iriarte’s resilient laminate from plastic. Fourth, even assuming that an “adhesion problem” exists in the case of Iriarte’s disclosed embodiment, the patentee has not shown, that the solution provided via using a plastic construction would not have been known to one with ordinary skill in the art. Finally, a claimed invention may be obvious for reasons other than that which led the inventors to the invention, and in this case there is independent reason for one with ordinary skill to select plastic as the construction material. For reasons discussed above, the patentee has not shown that the Examiner failed to make out a prima facie case of obviousness with respect to claims 30 and 56. 21Page: Previous 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 Next
