Appeal No. 2005-0821 Application No. 09/960,356 be described in the specification. See In re Buchner, 929 F.2d 660, 661, 18 USPQ2d 1331, 1332 (Fed. Cir. 1991). Thus the examiner should have determined whether the “fundamental” circuits for the analysis circuit portion 1B disclosed by appellant (specification, page 3, ll. 21-28) were well known in this art, or could have been practiced by one of ordinary skill in this art with only routine experimentation. In the absence of any underlying factual inquiries, we cannot sustain a rejection for lack of enabling disclosure. For the foregoing reasons and those stated in the Brief and Reply Brief, we determine that the examiner has not met the initial burden of proof in establishing failure to meet the “how to make and use” (enablement) requirement of section 112, first paragraph. Therefore we reverse the examiner’s rejection of claims 3 and 5 under 35 U.S.C. § 112, first paragraph. C. Summary The rejection of claims 3 and 5 for failing to fulfill the requirements of the first paragraph of 35 U.S.C. § 112 is reversed. The rejection of claims 3 and 5 for failing to meet the requirements of the second paragraph of 35 U.S.C. § 112 is also reversed. 7Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
