is established only when a single prior art reference

descriptive matter is necessarily present in the thing
described in the reference, and that it would be so recognized
by person of ordinary skill.'" In re Robertson, 169 F.3d 743,

1999) citing Continental Can Co v. Monsanto Co., 948 F.3d
1264, 1268, 20 USPQ2d 1756, 1749 (Fed. Cir. 1991).

or possibilities. The mere fact that a certain thing may
result for a given set of circumstances is not sufficient."
Id. citing Continental Can Co. v. Monsanto Co., 948 F.3d 1264,
