Opticurrent Survives Reexam, Moves Forward with CAFC Appeal on Damages

On February 12, the U.S. Patent and Trademark Office entered a notice of intent to issue an ex parte reexamination certificate on a patent owned by Opticurrent, LLC, which will confirm all challenged patent claims without any amendments or changes to the specification and drawings. The USPTO’s notice brings an end to a patent battle in which Opticurrent argued that Power Integrations engaged in some unusual gamesmanship to challenge the validity of patent claims asserted against it in district court.

Opticurrent Says Power Integrations Reexamination Attempt is Gamesmanship

On May 13, patent owner Opticurrent, LLC, filed an emergency motion for leave to file a supplemental motion for judgment  in a patent infringement case being fought out in the Northern District of California against high-performance semiconductor supplier Power Integrations, Inc. The motion, which ultimately asks the district court to render judgment on Power Integrations’ patent invalidity claims, alleges that the defendant has engaged in “gamesmanship” meant “to derail the Article III court system in the event of an adverse outcome on infringement by… manufacturing a race to an administrative outcome intended to circumvent the authority of this Court.” The case goes back to April 2016, when Opticurrent first filed charges against Power Integrations, alleging infringement of U.S. Patent No. 6958623, titled Three Terminal Noninverting Transistor Switch. Power Integrations followed with a counterclaim in which it asserted invalidity of the ‘623 patent, submitted expert discovery, and filed a motion for summary judgment of invalidity based on one of its alleged prior designs, but not based on any other reference contained within its invalidity contentions or expert report.
