Appeal No. 1999-1748 Application 08/846,285 The examiner should evaluate the patentability of appellants’ method claims under 35 U.S.C. § 103(a) based upon the acknowledged prior art methods converting exothermic weld metal material to weld metal (appellants’ specification, pages 1 through 3) and the teaching of Dahn. The examiner should review dependent article claim 23 and ascertain whether the method recitation “is punched and shaped” imparts to the “perforation distortion” structure a characteristic that distinguishes the perforation distortion from the pin holes effected by the removal of the beads of Dahn. The examiner may also consider remedying the following perceived informalities. Claim 22 appears to redundantly recite a perforation when a “perforation” distortion is set forth in claim 19. As to holes having “substantially equal” characteristics (claim 37), they appear to be the same as holes having “unequal” characteristics (claim 38). 13Page: Previous 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 NextLast modified: November 3, 2007
