Ex Parte Reexamination

USPTO Institutes All 10 Ex Parte Reexamination Petitions Filed by PVTECH; District Court Grants Stay of New Jersey Litigation

  • 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.
  • On April 24, 2026, the U.S. District Court for the District of New Jersey granted PVTECH’s motion to stay the litigation pending the outcome of the reexamination proceedings.
  • 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.
  • USPTO statistics show that in 78% of ex parte reexamination proceedings, claims are either cancelled or amended.

Xiamen, China – April 28, 2026 – PVTECH (XIAMEN PVTECH CORPORATION) today announced 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.

Following the USPTO’s institution of all 10 reexamination requests, Chief Judge Renee Marie Bumb of the District of New Jersey granted PVTECH’s motion to stay the litigation on April 24, 2026. PVTECH had filed its motion to stay on January 9, 2026, after submitting the first EPR request, and had filed all 10 requests by January 26, 2026. The Court found the stay appropriate given the early stage of the litigation and the USPTO’s decision to reexamine all asserted patents.

According to USPTO statistics, in 78% of ex parte reexamination proceedings, the USPTO either cancels all claims or issues a reexamination certificate with amended claims. In this matter, PVTECH challenged all 420 claims across the ten patents — not merely the 72 claims currently asserted by Super Lighting. With the case now stayed, the District Court litigation is expected to resume with a significantly narrowed scope of patents and claims.

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.

“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 be found invalid before the PTO. PVTECH will continue to vigorously defend its rights, and we look forward to a return to fair commercial competition in the market.”

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