Samsung has reached an out-of-court settlement regarding a patent infringement lawsuit over its Wireless PowerShare feature. The legal dispute, which lasted nearly four years, involved allegations that Samsung's reverse wireless charging technology violated a 2018 patent held by WiPQTUS Inc.
The lawsuit, filed in February 2023 in the U.S. District Court for the Eastern District of Texas, targeted multiple high-end Galaxy devices. The list of affected models included the Galaxy S10, S20, S21, and S22 series, as well as the Galaxy Note 10 and Note 20 series, and the Galaxy Z Flip and Z Fold lines.
WiPQTUS Inc., categorized as a non-practicing entity, claimed the Wireless PowerShare feature infringed on its 'Dual Mode Wireless Power Receiver' patent, numbered US 10,038,339. Renesas Electronics America Inc., the supplier of wireless charging chips for Samsung, also joined the case to defend its products.
On November 10, 2026, Samsung, Renesas, and WiPQTUS submitted a joint agreement to the court to settle the dispute. Under the terms, WiPQTUS agreed not to pursue further litigation against Samsung regarding this matter. The court did not issue a formal ruling on the infringement claims.
