In general, all the evidence a party seeks to rely upon in an inter partes review must be contained in either the Petition (for Petitioner) or Patent Owner Response (for Patent Owner). 37 C.F.R. § 42.123 (b), however, allows for the introduction of supplemental evidence, if such introduction is in the interests of justice.

Given the difficulty of meeting the “interests of justice” standard, we thought it worthwhile to discuss the rationale of this decision.

Id. Patent Owner, in seeking to introduce supplemental evidence, argued that the information at issue could not have been reasonably obtained earlier because the documents at issue were part of a litigation production consisting of over 100,000 pages.

Id. Petitioner further argued that it would suffer prejudice because it would not have time to prepare for the deposition of Patent Owner’s witness, to locate a rebuttal expert, and to prepare its reply.
Given the extensive nature of the document production, the fact that the supplemental information was limited and bore directly on Petitioner’s statements in the IPR, and that any prejudice to the Petitioner was negligible, the motion to submit supplemental information was granted. Id.
