Atlas Global Technologies has filed another patent infringement suit against Walmart, naming Vizio televisions and onn streaming devices and tablets. The October 2026 complaint concerns five Wi-Fi 6 patents acquired from Newracom, whose portfolio has already featured in Atlas’s litigation against TP-Link.
The case, 6:26-cv-00503, was filed in the U.S. District Court for the Eastern District of Texas. It follows a separate Atlas action against Walmart filed in April 2026.
For connected-device businesses, the connection is close to home: the accused technology is part of the wireless communication used by everyday consumer electronics. The filing brings the history of the Newracom portfolio into another dispute over products sold at retail.
Vizio televisions and onn devices named
Atlas alleges infringement through Walmart’s manufacture, use, sale, offer for sale and/or importation of products implementing Wi-Fi 6. It points to Walmart stores and walmart.com as distribution channels, including sales in the Eastern District of Texas.
The complaint identifies Vizio models including the M50QXM-K01, M65Q6-L4 and M75Q6-L4, together with numerous V4K, VQD, VQM and VQP models. It also names the onn 4K Pro Streaming Device, onn 4K Plus Streaming Device and onn Tablet Pro (2024 Model).
The allegations concern the devices’ wireless functions. They do not establish that the accused products infringe; that remains a question for the case.
The five patents came from Newracom
All five patents have assignment records identifying Newracom as the assignor and Atlas Global Technologies as the assignee. They cover several stages of wireless communication, from arranging data for transmission to coordinating responses from multiple devices.
| Patent | Technical subject |
| US9641234B2 | Preamble and payload for high-efficiency transmission |
| US9532187B2 | Interleaving data in a high-efficiency wireless LAN |
| US9912513B2 | Synchronisation for OFDMA transmission |
| US9825738B2 | Acknowledgement and multi-user transmission methods |
| US9763259B2 | Sounding to measure wireless channel conditions |
US9912513B2, for example, concerns coordination between an access point and wireless stations. Its first claim describes a device receiving a trigger frame, preparing an uplink frame and transmitting it using an allocated resource. The trigger frame also indicates the guard interval to use in the transmission.
That level of detail matters when comparing a patent with a television or streaming device. The analysis has to identify the operation performed by the device and match it to the asserted claim. Support for Wi-Fi 6 alone does not settle the question. The claim above is an illustration of the patent’s subject matter, rather than a confirmed claim asserted in this case.
A portfolio GreyB has followed before
GreyB’s earlier analysis of Newracom’s Wi-Fi 6 patent portfolio reported that Atlas acquired more than 200 U.S. patents from Newracom in 2021. It examined the litigation that followed and the patents that remained outside the acquisition.
- Four patents in the present Walmart case also appear in the TP-Link complaint list reproduced in that analysis: US9532187B2, US9912513B2, US9825738B2 and US9763259B2. The overlap concerns the complaint lists; it does not establish which claims supported the later verdict.
Atlas’s relationship with Acacia Research is recorded in the earlier Walmart case. Its corporate disclosure identifies Acacia Research Corporation and Acacia Research Group LLC as corporate parents.
Atlas’s Earlier Win against TP-Link
Before suing Walmart, Atlas had already won a Wi-Fi patent case against TP-Link. In September 2023, a jury awarded Atlas about $37.5 million. TP-Link appealed, but the appeals court upheld the judgment in June 2026.
Atlas has since brought two separate cases against Walmart: one in April 2026 and the October lawsuit discussed here. Each involves a different set of patents.
For companies following the October case, the TP-Link proceedings offer a starting point for reviewing earlier technical arguments and court rulings where the patents overlap. The $37.5 million award, however, does not tell us what Walmart might have to pay.
What This Case Means for Wi-Fi 6 Product Makers
More than five years after Atlas acquired Newracom’s patents, it continues to use them in new lawsuits. The Walmart case names televisions, streaming devices and a tablet—products with different uses that share Wi-Fi connectivity.
For companies selling similar devices, the next step is to check whether their products use the specific features covered by the five patents. Supporting Wi-Fi 6 alone does not answer that question. Teams need to compare the patent claims with how their devices work, then check existing licences and supplier agreements.
As the case develops, Atlas’s arguments and Walmart’s response should make the disputed features clearer. Those details will help other product makers judge how closely the case relates to their own devices.
