Enfish, LLC v. Microsoft Corporation, No. 15-1244 (Fed. Cir. May 12, 2016)

From the Opinion

The passage below is extracted verbatim from the opening of the document. It has not been editorially summarized — consult the full opinion for the court's complete reasoning.

Enfish sued Microsoft for infringement of several p a- tents related to a “self -referential” data base. On su m- mary judgment, the district court found all claims invalid as ineligible under § 101, some claims invalid as antic i- pated under § 102, and one claim not infringed. Enfish appeals. We find that the claims are not directed to an abstract idea, so we reverse the summary judgment based on § 101.
