Pvtech Achieves Perfect Record at USPTO: Institution of All 10 of 10 Ex Parte Reexamination Petitions Against Patents Asserted by Jiaxing Super Lighting

FOR IMMEDIATE RELEASE
April 24, 2026

• All 10 Ex Parte Reexamination requests filed by Pvtech against the 10 patents asserted by Jiaxing Super Lighting in the U.S. District Court for the District of New Jersey have been instituted by the USPTO as of April 21, 2026.
• Obtaining institution on all 10 of 10 requests represents a strong and uncommon success at the USPTO.
• The 10 EPRs challenge all 420 claims of the 10 patents — far beyond the 72 claims currently asserted in the litigation — and all 420 claims are now under active USPTO reexamination proceedings.

Finnegan client Pvtech (Xiamen Pvtech Corporation) announced today that the United States Patent and Trademark Office (USPTO) has instituted all 10 of 10 Ex Parte Reexamination requests targeting the 10 patents asserted by Jiaxing Super Lighting Electric Appliance Co., Ltd. and its affiliate Obert, Inc. against Pvtech in the ongoing patent infringement lawsuit filed in the U.S. District Court for the District of New Jersey.

The USPTO determined that each of the 10 requests raises substantial new questions of patentability, impacting every claim (420 claims in total) of the 10 patents and every one of the 72 claims currently asserted against Pvtech in the New Jersey litigation.

In addition, Pvtech has a pending motion to stay the New Jersey litigation pending resolution of the Ex Parte Reexamination proceedings and awaits the Court’s decision on that motion.

Achieving institution of all 10 of 10 EPR requests is a notable and uncommon accomplishment. This perfect record demonstrates broad vulnerability across the entire patent family, strengthens Pvtech’s pending motion to stay the New Jersey litigation, and sends a clear signal to the industry that the asserted patents face serious validity issues.

Pvtech has consistently maintained that the 10 patents asserted by Jiaxing Super Lighting are invalid and not infringed by Pvtech’s LED drivers and power solutions. While Pvtech is confident it does not infringe the asserted patents, it seeks the most efficient resolution of the dispute by invalidating the patents at the USPTO.

The USPTO’s decisions to institute reexamination on all 420 claims of the 10 patents strongly support Pvtech’s position and confirm the substantial merits of its challenges.

“These rulings represent a significant step forward in defending Pvtech’s innovative technology and protecting Pvtech’s customers from unwarranted litigation,” said Lionel Lavenue, lead counsel for Pvtech. “In particular, we are pleased to protect All Star, which has been unfairly targeted by Super Lighting. We remain confident that the asserted patents will fall as invalid before the PTO, and Pvtech will continue to vigorously defend its rights and press Super Lighting to compete freely in the market and avoid needless litigation over invalid and improperly asserted patents.”

Pvtech remains committed to delivering reliable, high-performance, and cost-effective LED power solutions without disruption from meritless patent assertions.
