In K/S HIMPP v. Hear-Wear Technologies, LLC, the Federal Circuit affirmed the decision of the Patent Trial and Appeal Board (PTAB) that upheld the decision of the Central Reexamination Unit Examiner that refused to hold claims obvious where the inter partes reexamination requestor had failed to provide any evidence that the claim element at issue was known in the art.

The Court did not dig deeper into the problem of establishing infringement when all of the steps of a method claim are not performed by a single party, and refused to review the Federal Circuit decision in Muniauction because it was not embraced by the petition for certiorari.
