This page is the campaign hub for suits by Atlas Global Technologies LLC, a Texas limited liability company, on patents it says are essential to the IEEE 802.11ax (Wi-Fi 6) standard. The Nintendo complaint alleges that Atlas became the owner of its asserted patents by an assignment dated February 19, 2021 from their original owner, which held them by assignment from the named inventors. It says the patents were invented by engineers at that company, which it describes as a major contributor to the 802.11ax standard, and that the company's contributions led to over 231 United States patents assigned to Atlas, 175 of which it says are essential to the standard.
The patents
The complaint in Atlas Global Technologies LLC v. Nintendo Co., Ltd., No. 2:26-cv-00993 (E.D. Tex.), asserts eleven patents: U.S. Patent 9,531,520, "Apparatus and Method for Downlink and Uplink Multi-User Transmissions," issued December 27, 2016; U.S. Patent 9,532,187, "Interleaver for Physical Layer Protocol Data Unit in a High Efficiency Wireless LAN," issued December 27, 2016; U.S. Patent 9,641,234, "Preamble and Payload for High Efficiency (HE) Transmission," issued May 2, 2017; U.S. Patent 9,763,259, "Sounding Method," issued September 12, 2017; U.S. Patent 9,825,738, "Acknowledgement Method and Multi User Transmission Method," issued November 21, 2017; U.S. Patent 9,832,058, "Apparatus and Method for Scrambling Control Field Information for Wireless Communications," issued November 28, 2017; U.S. Patent 9,848,442, "Method for Transmitting and Receiving Frame in Wireless Local Area Network," issued December 19, 2017; U.S. Patent 9,893,790, "Preamble and Payload for High Efficiency (HE) Transmission," issued February 13, 2018; U.S. Patent 9,912,513, "System and Method for Synchronization for OFDMA Transmission," issued March 6, 2018; U.S. Patent 10,020,919, "Protection Methods for Wireless Transmissions," issued July 10, 2018; U.S. Patent 11,050,539, "Pilot Transmission and Reception for Orthogonal Frequency Division Multiple Access," issued June 29, 2021.
The complaint in Atlas Global Technologies LLC v. Walmart Inc., No. 2:26-cv-00928 (E.D. Tex.), asserts five of them, the '187, '234, '259, '738, and '513 patents. That complaint says Atlas's earlier suit against Walmart, No. 2:26-cv-00317, asserted U.S. Patents 9,628,310, 10,020,919, 10,348,471, and 10,965,425. Four of the patents, the '187, '259, '738, and '513 patents, were tried with U.S. Patent 9,917,679 in No. 2:21-cv-00430 (E.D. Tex.), where the jury answered yes on September 14, 2023 to whether the defendants infringed any of the asserted claims and awarded $37,481,264 as a lump sum, in answer to a question that asked for a fair, reasonable, and nondiscriminatory (FRAND) royalty. The Federal Circuit affirmed on June 9, 2026 under its Rule 36.
The letter of assurance
The Nintendo complaint alleges that on March 11, 2015 the original owner submitted a Letter of Assurance for Essential Patent Claims to the IEEE, stating that it "may own, control, or have the ability to license Patent Claims that might be or become Essential Patent Claims." It alleges, on information and belief, that Nintendo monitors those letters of assurance, which it says are publicly available, and learns of essential patent claims as the patents issue. It also alleges, on information and belief, that Nintendo monitors the activities of other companies and so learned of the patents when Atlas sued them.
The earlier suits
The Nintendo complaint lists fourteen earlier Atlas suits involving the asserted patents, the first filed August 9, 2021 and the latest April 21, 2026. For venue, it cites four of them, Nos. 2:21-cv-00304, 2:21-cv-00430, 2:22-cv-00259, and 2:22-cv-00349, and says the court issued a claim construction order and conducted a trial in No. 2:21-cv-00430.
