Appeal 2006-2419 Application 10/238,297 application was filed, had possession of the claimed invention (Answer 3). The Examiner further finds that, for purposes of this rejection, “the time the application was filed” is considered to be the filing date of related Application No. 08/283,358, i.e., Aug. 1, 1994 (id.). Appellants do not dispute this effective filing date as found by the Examiner (see the Brief in its entirety). The Examiner finds that the Specification as filed discloses reaction components such as titanium powder, halide salts, and liquid alkali or alkaline earth metals (Answer 3). However, the Examiner ultimately finds that nothing in the original filed Specification would have conveyed the concept of those components together in gel form, as now claimed, to one of ordinary skill in the art (id.). The Examiner further finds that this gel form concept would not have been inherent in the disclosure as originally filed, and thus claims 21-33 contain “new matter” (Answer 4). The “written description” requirement of 35 U.S.C. § 112, first paragraph, requires an applicant to convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention, i.e., whatever is now claimed. See Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 1563, 19 USPQ2d 1111, 1117 (Fed. Cir. 1991). Whether this rejection is for “lack of support,” “new matter,” or “lack of written description,” the requirement is the same. See Vas-Cath, 935 F.2d at 1560, 19 USPQ2d at 1114. The initial burden of presenting a prima facie case of unpatentability, on any ground, rests with the Examiner. See In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992). “Thus, the burden placed on the examiner varies, depending upon what the applicant claims.
