This page is the campaign hub for patent suits by Electronic Edison Transmission Technologies, LLC, which its complaints describe as a Wyoming company based in Cheyenne, Wyoming. Every suit listed here asserts U.S. Patent 9,448,603. The suits were filed in the Eastern District of Texas, the Central District of California, the District of New Jersey, the District of Minnesota, and the Northern District of Texas.
The patent
U.S. Patent 9,448,603, "Transferring Power to a Mobile Device," issued September 20, 2016, from Application No. 13/472,447, filed May 15, 2012, which claims the benefit of a provisional application filed September 3, 2011. The USPTO copy lists Leigh M. Rothschild as the inventor and shows nine claims, all method claims, with claims 1, 6, and 8 independent. Each complaint alleges that Electronic Edison owns the patent by assignment.
Claim 8, the only claim asserted in the 2026 suits, recites a method for transferring power to a receptor mobile device from a donor mobile device having a battery: configuring a wireless power transfer mechanism on the receptor mobile device using a wireless receive application; determining a receptor power threshold using a wireless receive application; and receiving power from the donor mobile device and converting it into electric current using that mechanism, where the mechanism includes a power adapter having a coil, circuit elements to transfer power, and a capacitor to store electric charge that increases battery life when the capacitor is discharged. Claim 1 recites configuring a donor wireless power transfer mechanism on the donor device with a wireless transmit application and a receptor mechanism on the receptor device with a wireless receive application, transferring power between them, and converting it into electric current, where the donor mechanism includes a primary coil and the receptor mechanism includes a secondary coil and a capacitor.
The Samsung complaint also asserts U.S. Patent 9,871,415, issued January 16, 2018, and U.S. Patent 10,454,305, issued October 22, 2019, both also titled "Transferring Power to a Mobile Device." The USPTO copies show that the '415 patent issued from a continuation of the '603 patent's application and the '305 patent from a division of the '415 patent's application.
The phone, watch, and power bank suits
Electronic Edison Transmission Technologies, LLC v. Samsung Electronics Co., Ltd., No. 2:24-cv-00105 (E.D. Tex.), filed February 16, 2024, in the Marshall Division against Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc., pleads three counts. It alleges, upon information and belief, infringement of at least claims 1 to 4 and 8 of the '603 patent, claims 1 to 4 and 6 of the '415 patent, and claim 4 of the '305 patent by products including the Galaxy S20 series, Galaxy smartwatches, and Galaxy Z Fold phones that have a "Wireless PowerShare" or "Reverse Charging" feature and comply with the Qi wireless power standard.
Electronic Edison Transmission Technologies, LLC v. Google LLC, No. 2:24-cv-00335 (E.D. Tex.), filed May 7, 2024, in the Marshall Division, pleads one count on the '603 patent and alleges, upon information and belief, infringement of at least claims 1 to 4 and 8 by products including the Pixel 5, Pixel 6, Pixel 7, Pixel 7 Pro, and Pixel 8. Electronic Edison Transmission Technologies, LLC v. Motorola Solutions, Inc., No. 2:24-cv-00399 (E.D. Tex.), filed May 31, 2024, in the Marshall Division, pleads one count on the '603 patent and alleges, upon information and belief, infringement of at least claims 1, 4, and 8 by products including the Motorola Edge+, its example product, and the Motorola Edge 40, Edge 40 Pro, Edge, Razr+, Razr 40 Ultra, and Edge 30 Ultra, which it says implement the Qi wireless power standard and have "Wireless Power Sharing" functionality that transfers power wirelessly from one device's battery to another wireless charging compatible device. Electronic Edison Transmission Technologies, LLC v. Belkin International, Inc., No. 2:24-cv-10896 (C.D. Cal.), filed December 18, 2024, accuses wireless charging power banks such as BoostCharge and BoostCharge Pro, alleging, upon information and belief, infringement of at least claim 1 and, in later paragraphs, at least claims 1 to 4 and 8.
Electronic Edison Transmission Technologies, LLC v. Nothing Technology Limited, No. 2:25-cv-00974 (E.D. Tex.), filed September 23, 2025, in the Marshall Division, alleges, upon information and belief, infringement of at least claim 8 by products including the Nothing Phone 3, which it says supports Qi-compliant wireless reverse charging to another Qi-compatible Nothing device placed back to back with it. Each of these five complaints alleges direct infringement, including through internal testing and use, and induced infringement at least since service of the complaint, and each asks for an injunction or, in the alternative, a running royalty, along with damages under 35 U.S.C. 284. These are Electronic Edison's allegations.
The in-vehicle charging suits
The six 2026 complaints on this page, filed from July to October 2026, each plead one count asserting only claim 8 of the '603 patent against Qi-compatible wireless charging pads in vehicles. Each treats the vehicle as the donor mobile device and a Qi-compatible smartphone placed on the pad as the receptor mobile device; each alleges, upon information and belief, direct infringement at least through use and/or testing, along with induced and contributory infringement; and each states that because only a method claim is asserted, the marking requirements of 35 U.S.C. 287(a) do not apply.
Electronic Edison Transmission Technologies, LLC v. Hyundai Motor America, No. 2:26-cv-00592 (E.D. Tex.), filed July 17, 2026, in the Marshall Division, accuses Hyundai Wireless Charging, with the Hyundai Santa Fe as its example and the Palisade, Tucson, IONIQ 6, Sonata, and Kona also listed. Electronic Edison Transmission Technologies, LLC v.
