Appeal No. 2002-0582 Application No. 09/083,936 Oetiker, 977 F.2d at 1445, 24 USPQ at 1444. See also Piasecki, 745 F.2d at 1472, 223 USPQ at 788. An obviousness analysis commences with a review and consideration of all the pertinent evidence and arguments. "In reviewing the [E]xaminer's decision on appeal, the Board must necessarily weigh all of the evidence and arguments." In re Oetiker, 977 F.2d at 1445, 24 USPQ2d at 1444. "[T]he Board must not only assure that the requisite findings are made, based on evidence of record, but must also explain the reasoning by which the findings are deemed to support the agency's conclusion." In re Lee, 277 F.3d 1338, 1344, 61 USPQ2d 1430, 1434 (Fed. Cir. 2002). With these principles in mind, we commence review of the pertinent evidence and arguments of Appellant and Examiner. In the brief and supplemental brief, Appellant argues that neither Kakizoe nor Manthe either alone or in combination teach or suggest forming the gas blow-arc openings from the arc cover and the arc box. Appellant points out that this limitation is recited in each of the independent claims 6, 9 and 12. Appellant further points out that claims 7 and 8 also recite this limitation because they depend on claim 6. 44Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
