Example: | |||
''In re Samour'', | |||
571 F.2d 559 (Compound claims were rejected under | |||
35 U.S.C. 102(b) over a publication in view of two | |||
patents. The publication disclosed the claimed compound | |||
structure while the patents taught methods of | |||
making compounds of that general class. The applicant | |||
argued that there was no motivation to combine | |||
the references because no utility was previously | |||
known for the compound and that the 35 U.S.C. 102 rejection over multiple references was improper. The | |||
court held that the publication taught all the elements | |||
of the claim and thus motivation to combine was not | |||
required. The patents were only submitted as evidence | |||
of what was in the public's possession before applicant’s | |||
invention.) | |||

Example: | |||
''In re Baxter Travenol Labs.'', 952 F.2d | |||
388 (Baxter Travenol | |||
Labs. invention was directed to a blood bag system | |||
incorporating a bag containing DEHP, an additive | |||
to the plastic which improved the bag’s red blood cell | |||
storage capability. The examiner rejected the claims | |||
over a technical progress report by Becker which | |||
taught the same blood bag system but did not | |||
expressly disclose the presence of DEHP. The report, | |||
however, did disclose using commercial blood bags. It | |||
also disclosed the blood bag system as "very similar | |||
to [Baxter] Travenol’s commercial two bag blood | |||
container." Extrinsic evidence (depositions, declarations | |||
and Baxter Travenol’s own admissions) showed | |||
that commercial blood bags, at the time Becker’s | |||
report was written, contained DEHP. Therefore, one | |||
of ordinary skill in the art would have known that | |||
"commercial blood bags" meant bags containing | |||
DEHP. The claims were thus held to be anticipated.) | |||

See MPEP § 2112 - § 2112.02 for case law on inherency. | Example: | ||
''Atlas Powder Co. v. IRECO, Inc.'', | |||
190 F.3d 1342 (Two prior art references disclosed blasting | |||
compositions containing water-in-oil emulsions with | |||
identical ingredients to those claimed, in | |||
overlapping | |||
ranges with the claimed composition. The only element | |||
of the claims arguably not present in the prior | |||
art compositions was "sufficient aeration . . . entrapped to | |||
enhance sensitivity to a substantial degree." The Federal | |||
Circuit found that the emulsions described in | |||
both | |||
references would inevitably and inherently have "sufficient | |||
aeration" to sensitize the compound in the | |||
claimed ranges based on the evidence of record | |||
(including test data and expert testimony). This finding | |||
of inherency was not defeated by the fact that one | |||
of the references taught away from air entrapment or | |||
purposeful aeration.). ) | |||
*Note that as long as there is evidence of record establishing inherency, failure of those skilled in the art to contemporaneously recognize an inherent property, function or ingredient of a prior art reference does not preclude a finding of anticipation. | |||
See MPEP § 2112 - § 2112.02 for case law on inherency. Also | |||
note that the critical date of extrinsic evidence showing | |||
a universal fact need not antedate the filing date. | |||
