The Director of the US Patent & Trademark Office (PTO) overturned the Patent Trial & Appeal Board’s premature adverse judgment against a patent owner and remanded an inter partes review (IPR) proceeding based on the fact that the patent owner had initially instructed its counsel to cease work on the IPR while seeking new representation for related district court litigation, which contributed to the procedural delays. Shenzhen Xinzexing E-commerce Co., Ltd. v. Shenzhen Carku Technology Co., Ltd., IPR2024-00222 (PTO-Ofc. of Dir. July 10, 2024) (Vidal, PTO Dir.)

Shenzhen Xinzexing E-commerce Co. filed a petition for an IPR to challenge certain claims of a patent owned by Shenzhen Carku Technology Co. (Patent Owner). The petition and associated documents for the IPR were properly served on the Patent Owner at the address of record. The Board issued a notice on November 29, 2023, allowing the Patent Owner three months to file a preliminary response and requiring mandatory notice information to be submitted within 21 days. The Patent Owner did not comply with either obligation.

Following the Patent Owner’s failure to submit the required notices and response, the Board issued a sua sponte adverse judgment on May 21, 2024, interpreting the lack of response as abandonment of the IPR contest. However, on July 8, 2024, the Patent Owner filed the necessary notices and appointed new counsel, indicating that the previous counsel had been instructed to withdraw from the case and that new representation was being arranged.

The Director sua sponte overturned the Board’s adverse judgment, finding that it was premature. The Board’s communications did not clearly indicate that noncompliance with the notice requirements would result in adverse judgment. Given that the Patent Owner had shown efforts to rectify the situation by appointing new counsel and filing the required documents, the director vacated the adverse judgment and remanded the case for the Board to determine whether the petition showed a reasonable likelihood that any of the challenged patent claims were unpatentable.

Practice Note: This decision highlights the necessity of adhering to procedural deadlines and ensuring that consequences for noncompliance are clearly communicated. The Board’s failure to provide explicit notice of abandonment of the contest contributed to the premature adverse judgment, reinforcing the importance of clear procedural guidance.
