United States Federal Circuit

In a case involving a patent on Ultra High Molecular Weight Polyethylene for use in artificial joints, a patent examiner's rejection of all claims of a reissue application is affirmed, where the claims would have been obvious in light of the prior art, as substantial evidence supported the finding that a person of ordinary skill in the art would have been motivated to combine the early crosslinking step of one earlier patent with the process of another earlier patent to obtain the enhanced properties disclosed by the earlier patent that result from crosslinking prior to deformation.
