Nike sued Puma for infringement of seven Nike patents covering shoes having knitted upper, and alleged that after it notified Puma about the patents prior to filing suit, Puma not only failed to cease making and selling the accused products, Puma also introduced new shoes to the market that infringed the patents. Puma moved to dismiss the claims with respect to two of the patents as directed to non-patentable subject matter, asserting that one was directed to the abstract idea of forming an outline pattern on a textile and does not disclose an inventive step towards achieving the outline pattern, and that the second is directed to the abstract idea of generating a visual pattern on a textile, which is nothing more than a non-patentable work of art. Judge Sorokin disagreed, finding that the claims, which were directed to tangible manufactured items (i.e., shoes) or to physical components thereof or methods of manufacturing the same, they passed muster under the first prong of the Mayo test as being directed to a statutorily provided category of patent-eligible subject matter. He further noted that, even if they did not, Puma had not met its burden of demonstrating by clear and convincing evidence that the claims lacked an inventive step that would meet the second prong of the Mayo test. Judge Sorokin also denied Puma’s motion to dismiss the willfulness charges, finding Puma’s suggestion that more must be pled than knowledge of the patent and continued infringement remained an open question (albeit one that other Massachusetts judges had found incorrect), but that Nike had sufficiently pled additional facts that would support a finding of willfulness.
