The U.S. Court of Appeals for the Federal Circuit (CAFC) in a precedential decision today mostly upheld a district court ruling that found Chewy, Inc. did not infringe several claims of one IBM web advertising patent and that granted summary judgment of patent ineligibility on certain claims of another. The district court ultimately granted Chewy’s motion for summary judgment of noninfringement of claims 1, 2, 12, 14, and 18 of the ’849 patent and its motion for summary judgment that claims 13, 15, 16, and 17 of the ’443 patent were patent ineligible under Section 101.
