Palomar Technologies, Inc. v. MRSI Systems, LLC (18-cv-10236).

As a part of its defense to this patent infringement lawsuit, MSRI sought inter partes review in 2016. The patent emerged with most claims deemed valid. MSRI then challenged the validity of the patent over additional prior art references. MSRI sought to get around the estoppel provided by 35 USC 315(e)(2), which proscribes assertions of invalidity on grounds that were raised or could reasonably have been raised during the IPR, by providing declarations and search results from two outside search firms and asserting that these reasonable searches did not uncover the new references and thus the validity challenge could not reasonably have been raised. Magistrate Judge Bowler granted in part and denied in part MRSI’s motion to quash subpoenas issued by Palomar to the two search firms. She found that the searches were, at a minimum, subject to work-product protection, but that MSRI had waived such protection by affirmatively relying on the search results and affidavits in their opposition to Palomar’s motion for partial summary judgment. She determined that Palomar was entitled to discovery from the two firms, but that some of Palomar’s requests were overbroad and/or covered unrelated subject matter. Accordingly, while not quashing the subpoenas, she limited the subpoenas to specifics of the actual searches performed for MSRI.
