A reference disclosure can anticipate a claim when the reference describes the limitations but "'d[oes] not expressly spell out' the limitations as arranged or combined as in the claim, if a person of skill in the art, reading the reference, would ‘at once envisage’ the claimed arrangement or combination.” Kennametal, Inc. v. Ingersoll Cutting Tool Co., 780 F.3d 1376, 1381, 114 USPQ2d 1250, 1254 (Fed. Cir. 2015) (quoting In re Petering, 301 F.2d 676, 681(CCPA 1962)). In Kennametal, the challenged claim was to a cutting tool requiring a ruthenium binding agent with a physical vapor deposition (PVD) coating. The reference described all the elements of the claimed coated cutting tool but did not explicitly disclose the specific combination of ruthenium binding agent with a PVD coating. However, the reference disclosed that ruthenium was one of five specified binding agents and PVD was one of three suitable coating techniques. The Federal Circuit stated that the reference’s “express ‘contemplat[ion]’ of PVD coatings provided sufficient evidence that a reasonable mind could find that a person of skill in the art… would immediately envisage applying a PVD coating. Thus, substantial evidence supports the Board's conclusion that [the reference] effectively teaches 15 combinations, of which one anticipates pending claim 1. Though it is true that there is no evidence in [the reference] of ‘actual performance’ of combining the ruthenium binder and PVD coatings, this is not required.” Kennametal, 780 F.3d at 1383, 114 USPQ2d at 1255 (citations omitted).

Rather, Kennametal addresses whether the disclosure of a limited number of combination possibilities discloses one of the possible combinations.”).

When a claimed compound is not specifically named in a reference, but instead it is necessary to select portions of teachings within the reference and combine them, e.g., select various substituents from a list of alternatives given for placement at specific sites on a generic chemical formula to arrive at a specific composition, anticipation can only be found if the classes of substituents are sufficiently limited or well delineated. Ex parte A, 17 USPQ2d 1716 (Bd. Pat. App. & Inter. 1990). If one of ordinary skill in the art is able to “at once envisage” the specific compound within the generic chemical formula, the compound is anticipated. One of ordinary skill in the art must be able to draw the structural formula or write the name of each of the compounds included in the generic formula before any of the compounds can be “at once envisaged.” One may look to the preferred embodiments to determine which compounds can be anticipated.

In In re Petering, the prior art disclosed a generic chemical formula “wherein X, Y, Z, P, and R ' – represent either hydrogen or alkyl radicals, R a side chain containing an OH group.” The court held that this formula, without more, could not anticipate a claim to 7-methyl-9-[d, l ' -ribityl]-isoalloxazine because the generic formula encompassed a vast number and perhaps even an infinite number of compounds. However, the reference also disclosed preferred substituents for X, Y, Z, P, R, and R ' as follows: where X, P, and R ' are hydrogen, where Y and Z may be hydrogen or methyl, and where R is one of eight specific isoalloxazines. The court determined that this more limited generic class consisted of about 20 compounds. The limited number of compounds covered by the preferred formula in combination with the fact that the number of substituents was low at each site, the ring positions were limited, and there was a large unchanging structural nucleus, resulted in a finding that the reference sufficiently described “each of the various permutations here involved as fully as if he had drawn each structural formula or had written each name.” The claimed compound was 1 of these 20 compounds. Therefore, the reference “described” the claimed compound and the reference anticipated the claims.

A genus does not always anticipate a claim to a species within the genus.

See also In re Sivaramakrishnan, 673 F.2d 1383, 213 USPQ 441 (CCPA 1982) (The claims were directed to polycarbonate containing cadmium laurate as an additive. The court upheld the Board’s finding that a reference specifically naming cadmium laurate as an additive amongst a list of many suitable salts in polycarbonate resin anticipated the claims. The applicant had argued that cadmium laurate was only disclosed as representative of the salts and was expected to have the same properties as the other salts listed while, as shown in the application, cadmium laurate had unexpected properties. The court held that it did not matter that the salt was not disclosed as being preferred, the reference still anticipated the claims and because the claim was anticipated, the unexpected properties were immaterial.).

A genus does not always anticipate a claim to a species within the genus. However, when the species is clearly named, the species claim is anticipated no matter how many other species are additionally named. See Ex parte A, 17 USPQ2d 1716 (Bd. Pat. App. & Inter. 1990) (The claimed compound was named in a reference which also disclosed 45 other compounds. The Board held that the comprehensiveness of the listing did not negate the fact that the compound claimed was specifically taught. The Board compared the facts to the situation in which the compound was found in the Merck Index, saying that “the tenth edition of the Merck Index lists ten thousand compounds. In our view, each and every one of those compounds is ‘described’ as that term is used in [pre-AIA] 35 U.S.C. 102(a), in that publication.”). Id. at 1718.
