Failure to Disclose § 101 Defense in EDTX Initial Disclosures May Not Constitute Waiver​

The court denied plaintiff's motion to strike portions of the report of defendant's invalidity expert that included a previously undisclosed theory of unpatentability under 35 U.S.C. § 101, but reserved ruling on whether defendant waived that defense until trial. "[U]nlike some other districts’ Patent Rules, this district’s Patent Rules do not require a party to disclose an invalidity ground related to subject matter ineligibility under § 101. And because [the expert's] report does not identify any new factual basis for [defendant's] § 101 theory, no discovery violation has occurred. . . . Having said that, it is not clear why [plaintiff] has moved to 'strike' a portion of an expert report related to § 101 when both sides agree that invalidity under § 101 is not a jury issue. . . . Nor is it clear how [defendant] intends to raise its new § 101 invalidity theory when the time for filing motions for summary judgment has passed. If [defendant] intends to raise the theory for the first time during the JMOL phase of the case, the Court will address any waiver argument at that time."
