Appeal No. 2006-1218 Application No. 10/601,884 All of the claims on appeal are rejected under 35 U.S.C. §§ 102(b)/103(a) as being unpatentable over Sellers. Rather than reiterate the respective positions advocated by the Appellants and by the Examiner concerning these rejections, we refer to the brief and to the answer respectively for a complete exposition thereof.

The court in Best articulated this principle and the reasons therefore as follows: Where, as here, the claimed and prior art products are identical or substantially identical, or are produced by identical or substantially identical processes, the PTO can require an applicant to prove that the prior art products do not necessarily or inherently possess the characteristics of his claimed product. See In re Ludtke, [441 F.2d 660, 169 USPQ 563 (CCPA 1971)]. Whether the rejection is based on ‘inherency’ under 35 U.S.C. § 102, on ‘prima facie obviousness’ under 35 U.S.C. § 103, jointly or 3Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
