AAM v. Neapco – Part IV – Petition for Rehearing En Banc Denied – “Bad Vibrations”

This post will briefly discuss the Fed. Cir.’s denial of rehearing en banc – which  left the modified panel opinion stand. The lengthy panel opinion has been the subject of my last three posts, and you should read them before you read this one, since they contain lots of basic information about the split panel decision affirming most of the district court’s ruling that the AAM patent claims were not patent eligible.

AAM v. Neapco – Part III – The Dissent Faces a “Perfect Storm” of Conflated Doctrines

In American Axle and Manufacturing v. Neapco Holdings LLC, Appeal No. 2018-1763 (Fed. Cir., July 31, 2020), a split panel of Judges Dyk, Moore and Taranto, on rehearing, slightly modified their earlier opinion that most of the claims of U.S. Pat. No. 7,774,911 are invalid as an attempt to claim a law of nature, namely Hooke’s Law. The majority seems confused at times as to whether the claims are directed to an abstract idea or to a law of nature. See slip op. at 18 and 25. Moore strongly dissented. The claim that warranted the most discussion is Claim 22:
