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.

Before the Court is Plaintiff Headwater Research LLC’s Opposed Motion to Exclude Opinions of AT&T expert Mark Crovella regarding Non- Infringing Alternatives. Dkt. No. 138. Headwater puts forth two theories of exclusion, first it argues that AT&T ’s lack of disclosure warrants exclusion of certain NIA opinions, and second it argues that all of the NIA opinions are irrelevant because AT&T’s damages expert does not rely on them. The Court finds both arguments unavailing and thus DENIES the Motion. I.
