Appeal No. 94-3399 Application 07/871,374 disclosure as it would be interpreted by one having ordinary skill in the art. In re Kroekel, 504 F.2d 1143, 1146, 183 USPQ 610, 612 (CCPA 1974); In re Moore, 439 F.2d 1232, 1235, 169 USPQ 236, 238-39 (CCPA 1972). The examiner also improperly urged that having no antecedent for the particular words in question renders the claims per se indefinite. See Answer, pages 3 and 8. The effect of no antecedent basis for the particular words in claims, however, is dependent on the facts of each case. For lacking antecedent basis to render claims vague, one of ordinary skill in the art must not be able to ascertain the metes and bounds of the claimed subject matter, even when it is viewed in light of the teachings of the prior art and the supporting specification. In re Kroekel, supra; In re Moore, supra. However, the examiner, on this record, does not allege, much less explain, why having no antecedent for the particular words in question would have rendered the metes and bounds of the subject matter of claims 1 through 12 unascertainable by one of ordinary skill in the art. In view of the foregoing, we are constrained to reverse the examiner's rejection of claims 1 through 12 procedurally. 9Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
