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.

Saso Golf, Inc. owns U.S. Patent No. 5,645,495, which claims a particular golf club shape. Saso sued Nike, Inc. for infringing claim 7 of the patent. The U.S. District Court for the Northern District of Illinois held the claim invalid due to indefiniteness. Because we agree with the district court that claim 7 is indefinite, we affirm. I Claim 7 of the ’ 495 patent regards the shape of a golf club, specifically a wood.
