Appeal No. 1997-3221 Application No. 08/249,241 issues raised under 35 U.S.C. § 103. However, after considering the facts in this case we believe the better course of action is to move forward with a decision on the merits of this appeal. The initial burden of establishing reasons for unpatentability rests on the examiner. In re Oetiker, 977 F.2d 1443, 1446, 24 USPQ2d 1443, 1445 (Fed. Cir. 1992). Furthermore, to establish a prima facie case of obviousness, there must be both some suggestion or motivation to modify the references or combine reference teachings and a reasonable expectation of success. In re Vaeck, 947 F.2d 488, 493, 20 USPQ2d 1438, 1442 (Fed. Cir. 1991). Appellants argue (Brief47, page 5) that the amino acid sequence of the human GluR1B receptor as recited in the claims is not taught by Puckett. Appellants provide a table (Brief, page 6) highlighting the differences between Puckett and SEQ ID NO:2. In response the examiner states (Answer, bridging paragraph, pages 7-8): The simple fact that the nucleotide sequence of the DNA encoding the human glutamate receptor subunit of Puckett et al. is different from the DNA sequence of the instant invention does not defeat the instant rejection since the prior art of record provided a structurally similar composition and the motivation to isolate any analogous compound from any human brain cDNA library. The fact that this property differs slightly and inconsequentially from individual to individual does not support patentability since these difference[s] are the innate differences between naturally occurring compounds and do not constitute an inventive contribution by [a]ppellant. We remind the examiner that generalization is to be avoided insofar as specific structures are alleged to be prima facie obvious one from the other. 47 Paper No. 17, received June 25, 1996. 49Page: Previous 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 NextLast modified: November 3, 2007
