Appeal No. 2004-0526 Application No. 09/981,975 to advance any factual basis to support his conclusion to the effect that it would have been obvious to one of ordinary skill in the art to modify the tools of Dossier or Colvin such that the connection surfaces comprise concave and convex surfaces defining arcs having the same radius, as now claimed. Rather, the examiner’s stated position appears to be based on impermissible hindsight gleaned from appellants’ own disclosure. This of course is improper. In re Fritch, 972 F.2d 1260, 1266, 23 USPQ2d 1780, 1784 (Fed. Cir. 1992). Concerning the examiner’s argument on page 2 of the final rejection that the claimed subject matter would have been obvious because there is no clear indication from the original specification that the claimed “ranges” are critical, we note that criticality is not a requirement of patentability. See W. L. Gore & Assocs. v. Garlock, Inc., 721 F.2d 1540, 1556, 220 USPQ 303, 315 (Fed. Cir. 1983), cert. denied, 469 U.S. 851 (1984). For the reasons stated above, we cannot support the examiner’s rationale for rejecting the appealed claims. Accordingly, we shall not sustain the examiner’s rejection of claims 1-4 and 7-9 under 35 U.S.C. § 103(a). 5Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
