holding that finding all shapes to be equivalent structure would entirely vitiation the limitation requiring a “generally conical shape” (emphasis added) | holding that the patentee’s theory of equivalence' — -that “any shape would be equivalent to the conical limitation” — would write such a limitation out of the claims (emphasis in original) | holding that an earlier application failed to meet the written description necessary to support two claims of the patent at issue, and thus denying entitlement to the earlier filing date for those two claims | holding a claim invalid for failure to satisfy the written description requirement when the specification did not disclose all cup shapes literally or “inherently” | finding that statements distinguishing prior art and promoting advantages of conical shaped cup for use in an artificial hip device in patent’s specification “make clear that that [patent] discloses only conical shaped cups and nothing broader” | reversing JMOL denial where cited patent passage was “reviewing the prior art and did not describe the inven- tion” | reversing JMOL denial where cited patent passage was “reviewing the prior art and did not describe the inven- tion” | stating issue of compliance with written description requirement is question of fact | “[M]issing descriptive matter must necessarily be present in the . . . specification such that one skilled in the art would recognize such a disclosure.” (citing Cont’l Can Co. USA v. Monsanto Co., 948 F.2d 1264, 1268 (Fed. Cir. 1991)) | “[M]issing descriptive matter must necessarily be present in the . . . specification such that one skilled in the art would recognize such a disclosure.” (citing Cont’l Can Co. USA v. Monsanto Co., 948 F.2d 1264, 1268 (Fed. Cir. 1991)) | "If a theory of equivalence would vitiate a claim limitation, however, then there can be no infringement under the doctrine of equivalents as a matter of law." | Statements that the prior art is “inferior” “make clear that the [parent patent] discloses only conical shaped cups and nothing broader.” | specification distinguished prior art as inferior and touted advantages of a conical shaped cup for use in an artificial hip device; "such statements make clear that the '589 patent discloses only conical shaped cups and nothing further" | also noting that the district court had found that the written description “ ‘does not attempt to identify other, equally functional shapes or talk in terms of a range of shapes....’ ” | “Another extremely important aspect of the present device resides in the configuration of the acetabular cup as a trapezoid or a portion of a truncated cone.” | “If a theory of equivalence would vitiate a claim limitation ... then there can be no infringement under the doctrine of equivalents as a matter of law.” | “[D]isclosure in a parent application that merely renders the later-claimed invention obvious is not sufficient to meet the written description requirement; the disclosure must describe the claimed invention with all its limitations.” | “the [parent] application discloses only conical shaped cups and nothing broader”
