AT&T, Verizon and T-Mobile beat Asus patent claims in Texas
A federal jury in the Eastern District of Texas on August 26, 2026 cleared AT&T, Verizon, and T-Mobile of wireless patent infringement claims brought by Asus Technology Licensing and Celerity IP. Jurors found no infringement on three patents, ruled them invalid, and rejected a $436 million damages request in the asus att verizon tmobile dispute.
The unanimous verdict delivered in Marshall, Texas, ends a high-stakes chapter in a consolidated lawsuit tied to 4G and 5G network rollout. Nokia and Ericsson, whose equipment sits at the center of the dispute, also emerged as winners after intervening to defend their products and carrier customers.
Key Takeaways
- A Marshall, Texas jury cleared AT&T, Verizon, and T-Mobile of infringing three wireless communications patents on August 26, 2026.
- Jurors also found the asserted patents—U.S. Nos. 10,798,754, 10,951,359, and 9,560,559—invalid, blocking a $436 million damages claim.
- Plaintiffs Asus Technology Licensing, Innovative Sonic, Celerity IP and ASUSTeK sued the carriers in 2023 over Ericsson and Nokia network gear.
- Intervenors Nokia and Ericsson won alongside the carriers; IAM reported jurors also sided against plaintiffs on FRAND licensing obligations.
- The outcome shields major U.S. wireless infrastructure from a costly licensing bill tied to standard-essential patent claims.
What did the jury decide in the Asus patent trial?
On Wednesday, August 26, 2026, a jury in the U.S. District Court for the Eastern District of Texas ruled that AT&T, Verizon, and T-Mobile did not infringe three patents related to wireless communications. According to Reuters, the jury also concluded that the carriers proved the patents are invalid.
The patents cover core cellular technologies: quality-of-service flow handling, control resource set configuration, and small cell enhancements. Together, they sit at the heart of how modern 4G and 5G networks manage traffic and coverage.
Celerity IP and its co-plaintiffs had sought $436 million in damages. The jury denied that request entirely, delivering a clean sweep for the defense.
Who sued the carriers—and over what?
The consolidated case was brought by ASUSTeK Computer, Asus Technology Licensing, Innovative Sonic, and licensing partner Celerity IP LLC. The groups filed suit in 2023, accusing AT&T, Verizon, and T-Mobile of infringement through their deployment of Ericsson and Nokia mobile network equipment.
Because the alleged infringement flowed through vendor gear rather than handset software, Ericsson and Nokia stepped in as intervenors. Both companies defended their network products and the carriers that rely on them to deliver nationwide wireless service.
As IAM Patent noted, the dispute centered on wireless standard-essential patent (SEP) claims. Plaintiffs also sought declarations that their FRAND licensing conduct complied with ETSI policy and competition law—arguments the jury rejected.
Why does this verdict matter for U.S. wireless networks?
Patent fights over cellular standards can ripple far beyond a courtroom. Licensing fees tied to SEP portfolios, if enforced broadly, can raise costs for carriers building and upgrading 5G towers—and those costs often flow downstream to consumers.
By clearing all three major U.S. carriers at once, the verdict removes an immediate $436 million liability and reinforces a broader trend of courts scrutinizing patent validity in telecom disputes. For anyone tracking how Future Tech & AI Wonders intersect with telecom law, the case shows infrastructure patents face stiff challenges at trial.
The Eastern District of Texas has long been a favored venue for patent holders, yet recent outcomes suggest juries there are willing to invalidate asserted patents when defendants mount strong validity defenses. AT&T, Verizon, and T-Mobile now avoid a precedent-setting loss that could have emboldened similar suits against other operators.
What happens next in the Celerity IP litigation?
Plaintiffs may appeal the jury's findings on infringement, validity, and FRAND obligations, though no appeal has been announced as of this report. Related antitrust and tort claims in the broader Celerity IP litigation may continue separately, depending on how the cases were consolidated and severed for trial.
For now, the Big Three carriers—and the network vendors that stood beside them—can keep deploying Ericsson and Nokia equipment without the shadow of this particular damages award. The industry will watch whether Celerity IP and Asus pursue further patent assertions in their ongoing Eastern District of Texas portfolio.
