Appeal No. 2003-0936 Application No. 09/532,806 examiner argues that “Claim 1 encompasses every subfragment of SEQ ID NO:1 that is between 95 and 3536 contiguous bases long and that has promoter function” (EA 5; emphasis added). According to the examiner, “the description must allow those skilled in the art to recognize what regions of SEQ ID NO:1 would need to be retained in its subfragments such that the subfragments could reasonably be expected to retain promoter function” (EA 6). As we understand the rejection, the examiner concedes that appellants’ specification describes every subfragment claimed which can function as a promoter. However, that description does not satisfy the written description requirement of 35 U.S.C. § 112, first paragraph, because the subfragments of SEQ ID NO:1 between 95 and 3536 contiguous bases in length that can function as a promoter are not distinguished from the subfragments of SEQ ID NO:1 between 95 and 3536 contiguous bases in length that cannot function as a promoter. The problem with the examiner’s position is that it confuses the written description requirement of 35 U.S.C. § 112, first paragraph, with the enablement requirement of 35 U.S.C. § 112, first paragraph. For example, in support of the written description requirement of 35 U.S.C. § 112, first paragraph, the examiner states (EA 5-6)(emphasis added): 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
