Appeal 2007-0493 Application 10/289,967 Patent 6,144,380 142 F.3d at 1483, 45 USPQ2d at 1650 and Clement, 131 F.3d at 1469, 45 USPQ2d at 1165. This factual background more fully illuminates the Federal Circuit’s determination in Pannu that the reissued claims were not narrowed in any material respect compared with their broadening. This determination is not based on the fact that the narrowing limitations of the reissue claims were unrelated to their broadening. Rather, it is based on the fact that these same or similar limitations had been prosecuted in the original patent application and therefore were not overlooked aspects of the invention and did not materially narrow the reissue claims. The reissue claims in Clement were both broader and narrower in aspects germane to a prior art rejection. 131 F.3d at 1470, 45 USPQ2d at 1165. However, the narrower limitation recited in the Clement reissue claims (“at least 59 ISO in the final pulp”; see clause (e) of reissue claim 49) also was recited in the patent claims (see clause (f) of patent claim 1). 131 F.3d at 1470, 1474, 45 USPQ2d at 1165, 1169. Therefore, the narrowing limitation of Clement, like Pannu, was not overlooked during original prosecution and did not materially narrow the reissue claim. Additionally, in setting forth the test for recapture Clement states in part that “if the reissue claim is narrower in an aspect germane to prior art rejection, and broader in an aspect unrelated to the rejection, the recapture rule does not bar the claim” and specifically states that “Ball is an example of (3)(b).” 131 F.3d at 1470, 45 USPQ2d at 1165. The claims before the court in Ball were determined by the trial judge to be materially narrower as - 42 -Page: Previous 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 Next
