Appeal No. 2006-2076 Application No. 09/747,651 The appellants specification states: “Another solution to this problem [tracking transactions] involves the use of what are known as ‘tracer images.’ This generally involves merchants providing to all interested shopping applications data that uniquely identifies particular transactions and then relying upon shopping applications to claim origination of certain transactions” (page 5, lines 15-18). The relevant inquiry under 35 U.S.C. § 112, second paragraph, is whether the claim language, as it would have been interpreted by one of ordinary skill in the art in light of the appellants’ specification and the prior art, sets out and circumscribes a particular area with a reasonable degree of precision and particularity. See In re Moore, 439 F.2d 1232, 1235, 169 USPQ 236, 238 (CCPA 1971). The examiner’s mere assertion that the function and implementation of the appellants’ tracer image are unclear does not provide the required explanation as to why the claim language, as it would have been interpreted by one of ordinary skill in the art in light of the appellants’ specification and the prior art, fails to set out and circumscribe a particular area with a reasonable degree of precision and particularity. Accordingly, we reverse the rejection of claims 7 and 21 under 4Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
