Newshot After Nearly 4 Years, Samsung's Reverse Wireless Charging Patent Lawsuit Reaches Settlement
IT Home, November 12 news: Samsung has reached a settlement in the patent infringement lawsuit related to the Wireless PowerShare (wireless shared charging) feature on Galaxy phones. The legal dispute lasted nearly four years and involved multiple devices Samsung has released since 2019, including the Galaxy S10 series and Galaxy Note 20 series, among others.
Wireless PowerShare is a reverse wireless charging feature on Samsung Galaxy phones. Users simply place a Galaxy Watch, Galaxy Buds, other Galaxy phones that support wireless charging, and devices compatible with the Qi wireless charging standard on the back of the phone to wirelessly charge these devices using the phone.
According to IT Home's understanding, the lawsuit was filed by WiPQTUS Inc. in a U.S. court in February 2023, with Samsung Electronics as the defendant. WiPQTUS alleged that the Wireless PowerShare feature on Samsung Galaxy phones infringed a patent it obtained in 2018, titled "Dual Mode Wireless Power Receiver," patent number US 10,038,339.
The lawsuit documents listed multiple high-end Samsung Galaxy phones, including the Galaxy S10, Galaxy S20, Galaxy S21, and Galaxy S22 series, as well as the Galaxy Note 10 and Galaxy Note 20 series, and also involved the Galaxy Z Flip and Galaxy Z Fold series.
WiPQTUS Inc. is classified as a non-practicing entity (NPE), commonly known as a patent operating company. Such companies do not produce or sell products themselves; instead, they generate revenue by holding patents and filing infringement lawsuits against other companies.
After Samsung Electronics was sued in the U.S. District Court for the Eastern District of Texas, the supplier that provides it with wireless charging chips also joined the legal dispute to protect the rights and interests of the relevant chip products.
Chip supplier Renesas Electronics America Inc. subsequently filed a counterclaim against WiPQTUS, attempting to prove that the chips it supplied did not infringe the other party's patent.
On November 10, 2026, Samsung, Renesas, and WiPQTUS submitted a joint agreement to the court, announcing that the three parties had reached an out-of-court settlement and that all patent infringement allegations had been withdrawn.
Under the agreement, WiPQTUS promised that it will not sue Samsung again in the future over this disputed matter.
As a result, the court did not make a formal ruling on whether Samsung actually infringed the relevant patent. At present, the judge is expected to formally close the case within the next few days.
This also means that the patent dispute, which lasted nearly four years, ultimately ended in an out-of-court settlement, but whether Samsung actually committed patent infringement has not been determined by the court.
