Appeal No. 2004-0119 Application 08/644,170 in a single jaw closing operation, we see no teaching, suggestion or motivation in the remaining references applied by the examiner which would have led one of ordinary skill in the art to then consider forming the crimping tool of Mino from a relatively soft metal like aluminum, thereby creating a problem situation which would subsequently also require a dense anodic coating to be applied on the outer surfaces of the aluminum tool to enhance wear properties thereof. As urged by appellants in their brief and reply brief, none of the references applied by the examiner would have led one of ordinary skill in the art at the time of appellants’ invention to make a tool with wear susceptible elements like those in the crimper of Mino out of aluminum. Instead, it appears that the prior art would have led the ordinarily skilled worker to use a known hard material, such as steel, for such a tool, or at least for the wear susceptible elements thereof. In our view, the examiner’s position in this appeal represents a clear case of impermissible hindsight reconstruction of the claimed invention based on appellants’ own teachings. In that regard, we note, as our court of review indicated in In re Fritch, 972 F.2d 1260, 1266, 23 USPQ2d 1780, 1783 (Fed. 7Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
