Appeal No. 1998-2884 Application No. 08/495,960 limitations." Wertheim, 541 F.2d at 262, 191 USPQ at 96 citing In re Smythe, 480 F.2d 1376, 1382, 178 USPQ 279, 284 (CCPA 1973). In view of the above discussion, it is our conclusion that, under the factual situation presented in the present case, the statutory written description requirement has been satisfied because Appellant was clearly in possession of the invention at the time of filing of the application. Therefore, we do not sustain the rejection of claims 13-19 and 21 under the first paragraph of 35 U.S.C. § 112. Turning to a consideration of the 35 U.S.C. § 112, second paragraph, rejection of claims 13-19 and 21, we note that the general rule is that a claim must set out and circumscribe a particular area with a reasonable degree of precision and particularity when read in light of the disclosure as it would be by the artisan. In re Moore, 439 F.2d 1232, 1235, 169 USPQ 236, 238 (CCPA 1971). Acceptability of the claim language depends on whether one of ordinary skill in the art would understand what is claimed in light of the specification. Seattle Box Co. v. Industrial Crating & Packing, Inc., 731 F.2d 818, 826, 221 USPQ 568, 574 (Fed. Cir. 1984). 9Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
