In Medtronic, Inc. v. Endotach LLC, IPR2014-00100, Paper 32 (August 28, 2014), the petioner filed a Supplemental Notice of Deposition of patent owner’s witness, indicating that its cross-examination of the witness “may rely on,” among other things, a prior declaration by the witness filed in district court and three U.S. patents.  The patent owner requested a conference with the Board because such cross- examination necessarily would be outside the scope of the direct testimony set forth in his IPR Declaration.

The Board disagreed with the Patent Owner, noting:

We contemplate multiple scenarios in which other documents may be used for cross-examining a witness, while staying within the scope of his or her direct testimony. The fact that a document is not cited or discussed in a declaration is not dispositive for purposes of enforcing § 42.53(d)(5)(ii).
