Appeal No. 1999-2225 Application No. 08/815,441 F.2d 1557, 1561, 27 USPQ2d 1510, 1513 (Fed. Cir. 1993). As long as "undue experimentation" is not involved, a specification would comply with the enablement requirement of the statute even if a reasonable amount of routine experimentation is necessary to practice the claimed invention. Enzo Biochem Inc. v. Calgene, 188 F.3d 1362, 1371, 52 USPQ2d 1129, 1135 (Fed. Cir. 1999). Even "a considerable amount of experimentation is permissible, if it is merely routine, or if the specification in question provides a reasonable amount of guidance with respect to the direction in which the experimentation should proceed..." Wands, 858 F.2d at 737, 8 USPQ2d at 1404. Here, the examiner has not undertaken the analytic framework, as set out in Wands, for determining whether one skilled in the relevant art would be subject to "undue experimentation" in making and using the claimed invention. For this reason alone, the examiner has failed to carry the initial burden of proof. The examiner fails to understand that a rejection under 35 U.S.C. § 112, first paragraph, must take into account various the nature of the invention; (5) the state of the prior art; (6) the relative skill of those in the art; (7) the predictability or unpredictability of the art; and (8) the breadth of the claims. In re Wands, 858 F.2d 731, 735, 736-37, 8 USPQ2d 1400, 1402, 1404 (Fed. Cir. 1988). 5Page: Previous 1 2 3 4 5 6 7 NextLast modified: November 3, 2007
