Powermat Technologies has launched a patent infringement suit against Anker Innovations and related entities in the Unified Patent Court's Munich division, marking a major escalation in the companies' ongoing global dispute over wireless charging technology.
Filed in March 2025, the complaint targets two European patents: EP 2,564,403, titled System and Method for Transferring Power Inductively Over an Extended Region, and EP 2,266,123, titled Inductive Transmission System. Because the suit was filed under the jurisdiction of the Unified Patent Court (UPC), any decision could have effect across all participating UPC member states.
Named defendants include Fantasia Trading LLC, Anker Innovations Technology Co. Ltd., Anker Innovations Ltd., Anker Technology (UK) Ltd., Anker Innovations Deutschland GmbH, and Anker Innovations (Netherlands) B.V.
The UPC action follows a parallel U.S. patent infringement suit Powermat filed in the Eastern District of Texas in June 2023. That case involves seven U.S. patents: U.S. Patent Nos. 8,283,812; 8,626,461; 9,048,696; 8,981,598; 9,006,937; 9,083,204; and 8,049,370.
Anker responded by challenging three of those patents — the '696, '204, and '461 patents — at the Patent Trial and Appeal Board. Between December 2024 and February 2025, the PTAB instituted inter partes review proceedings for all three, signaling a likelihood that at least one claim in each patent may be invalidated.
With the initiation of litigation in the UPC, the patent battle between Powermat and Anker has now expanded from the U.S. to Europe, raising the stakes for both sides in the highly competitive wireless charging market.
