Appeal No. 1996-0331 Application 08/239,942 John L. Hawkins, (Hawkins), "Clipper Developers Convene," DATA BASED ADVISOR, August 1989, pages 136 et seq. [hereinafter, pages 1 to 6 as refered to by us in the instant opinion]. Claims 1 and 31 stand rejected under 35 U.S.C. § 102(b) as being anticipated by Hawkins. Rather than repeat the positions of appellants and the examiner, reference is made to the Brief, Reply Brief, and the Answer for the respective details thereof. OPINION In reaching our conclusion on the issues raised in this appeal, we have carefully considered appellants’ specification and claims, the applied reference, the respective viewpoints of appellants and the examiner, and all other evidence of record. We find, for the reasons that follow, that the feature recited in claims 1 and 31 on appeal, of providing a method of altering an existing data structure using a change definition language, is not taught by the prior art applied by the examiner. Accordingly, we will reverse the decision of the examiner rejecting claims 1 and 31 on appeal. At the outset, we note that a prior art reference anticipates a claim only if it discloses, either explicitly or inherently, every limitation of the claimed invention. In re Schreiber, 128 F.3d 1473, 1477, 44 USPQ2d 1429, 1431 (Fed. Cir. 1997). For an unstated element to be found inherent in an anticipating reference, it must exist as a matter of scientific fact and flow naturally from the elements expressly disclosed in the prior art reference. Id. However, inherency may not be established by probabilities or possibilities regarding what may have resulted in the prior art. In re Oelrich, 666 F.2d 578, 581, 212 USPQ 323, 326 (CCPA 1981).
