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.

Nassau P recision Casting Co., Inc., owns United States Patent No. 5,486,000, entitled “Weighted Golf Iron Club Head.” In September 2010, Nassau sued Acushnet Company, Inc., Cobra Golf Company, and Puma North America, Inc. (collectively, “Acushnet”) for infringement of the ’000 patent. Nassau appeals from a decision of the United States District Court for the Eastern District of New York that granted Acushnet’s motion for summary judgment of non- infringement. For the reasons set out below, we affirm in part, vacate in part, and remand.
