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.

Finjan LLC sued Sonic Wall, Inc. for patent infringe- ment in the United States District Court for the Northern District of California. Because the district court based its judgment of invalidity on a collateral estoppel decision that we have since vacated, we vacate the district court’s judg- ment of invalidity and remand for further proceedings. We also affirm the district court’s grant of summary judgment of noninfringement and the district court’s decision to ex- clude Finjan’s expert analysis. I.
