Appeal No. 2002-2318 Application 09/652,520 Pirolli with Pouschine. On Page 5 of the answer, the examiner suggests that Pouschine’s teaching essentially invites one of ordinary skill in the art to “investigat[e] techniques for deciding what to pre-calculate.” Thus, the examiner seems to suggest that it would have been obvious to try various techniques in the system of Pouschine so that one of ordinary skill in the art could decide what to pre- compute [answer, page 5]. However, it is well settled that the "obvious to try" standard does not constitute obviousness. In re Deuel, 51 F.3d 1552, 1559, 34 USPQ2d 1210, 1216 (Fed. Cir. 1995)(“A general incentive does not make obvious a particular result, nor does the existence of techniques by which those efforts can be carried out.”). Merely because Pouchine’s modeling system does not require pre-calculation of all data cells is hardly an adequate reason why the skilled artisan would rely on Pirolli’s teaching of using a threshold to determine the most visited web pages. We are compelled to find that the only motivation for combining Pirolli with Pouschine stems from impermissible hindsight by reconstructing the invention using the claims as a template. We recognize that “[a]ny judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning.” Ex parte Rodgers, 27 USPQ2d 1738, 1748 (Bd. Pat. App. & Int’f 1992). However, such a reconstruction must not include knowledge gleaned solely from appellants’ -8-Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
