Appeal No. 2004-0131 Application No. 08/462,531 967, 969, 169 USPQ 795, 796 (CCPA 1971). In view of the above, we determine that there is written description support for claims 2-4, 6-9, 15-22, and 24-32 under 35 U.S.C. § 112, first paragraph, and therefore, we reverse the objection to the specification and rejection of these claims under 35 U.S.C. § 112, first paragraph (written description). II. The 35 U.S.C. § 112, First Paragraph, Rejection (enablement) The first paragraph of 35 U.S.C. § 112, with regard to enablement, requires that the specification enable a person having ordinary skill in the art to make and use the claimed invention. Further, enablement requires that the specification teaches those having ordinary skill in the art to make and use the invention without “undue experimentation.” In re Vaeck, 947 F.2d 488, 495-96, 20 USPQ2d 1483, 1444-45 (Fed. Cir. 1991). Also, it is well settled that the examiner has the burden of providing a reasonable explanation, supported by the record as a whole, why the assertions as to the scope of objective enablement set forth in the specification are in doubt, including reasons why the description of the invention in the specification would not have enabled one of ordinary skill in this art to practice the claimed invention without undue experimentation, in order to establish a prima facie case under the enablement requirement of the first paragraph of § 112. In re Wright, 999 F.2d 157, 1561, 27 USPQ2d 1510, 1513 (Fed. Cir. 1993); In re Marzocchi, 439 F.2d 220, 223-24, 169 USPQ 367, 369-70 (CCPA 1971). We determine that the examiner has not met this burden for the following reasons. As mentioned in Section I, supra, in the instant case, the examiner objects to the specification and rejects the claims 2-4, 6-9, 15-22 and 24-32, stating that “[t]he combination of a shoe -11-Page: Previous 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 NextLast modified: November 3, 2007
