Samsung settles patent lawsuit related to Wireless PowerShare on Galaxy phones

TL;DR

Samsung has settled a nearly four-year patent dispute over Wireless PowerShare on Galaxy phones.

The case involved reverse wireless charging on many Galaxy models, including the S10, Note 20, S series, and foldables.

All claims were withdrawn in an out-of-court deal, and Samsung cannot be sued again over this issue.

Samsung has settled a patent infringement lawsuit related to the Wireless PowerShare feature on Galaxy phones. The legal battle lasted nearly four years and involved several devices released since 2019, including the Galaxy S10 series and the Galaxy Note 20 series.

This feature allows users to wirelessly charge their Galaxy Watches, Galaxy Buds, compatible Galaxy phones, and other Qi-compatible devices by placing them on their Galaxy phone's back.

WiPQTUS claimed that Samsung used its patented reverse wireless charging technology without paying for it

The lawsuit was filed by WiPQTUS Inc. against Samsung Electronics in February 2023. It alleged that the Wireless PowerShare feature in Galaxy phones infringed upon its 2018 patent titled “Dual Mode Wireless Power Receiver” (US Patent 10,038,339).

The complaint named several high-end Galaxy phones, starting with the Galaxy S10 and including the Galaxy S20, Galaxy S21, Galaxy S22, Galaxy Note 10, Galaxy Note 20, Galaxy Z Flip series, and Galaxy Z Fold series.

WiPQTUS Inc. is described as a Non-Practicing Entity (NPE), which means it doesn't manufacture or sell products. Instead, it exists simply to generate revenue by suing companies over patents it holds.

After Samsung Electronics was sued in the US District Court for the Eastern District of Texas, the firm that supplied wireless charging chips joined the legal battle to defend its components. Renesas Electronics America Inc. filed a countersuit against WiPQTUS Inc. to prove its chips did not infringe upon the patent.

Samsung and WiPQTUS settled the matter out of the court

On November 10, 2026, Samsung, Renesas, and WiPQTUS submitted a joint agreement stating that all patent infringement claims had been withdrawn as part of an out-of-court settlement. Under the agreement, WiPQTUS will never sue Samsung over this issue again.

As a result, the court did not issue a formal ruling on whether infringement actually occurred, and the judge is expected to close the case within the next few days.
