Wireless Alliance v. T-Mobile: LTE Patent Suit Ends in Dismissal With Prejudice
Wireless Alliance, LLC filed suit against T-Mobile USA in the Eastern District of Texas asserting three patents covering LTE carrier aggregation and uplink/downlink separation methods. After 657 days of litigation, all claims were dismissed with prejudice by joint motion — alongside parallel suits against AT&T and Verizon — suggesting a coordinated resolution across the industry.
Coordinated LTE patent dismissal spans AT&T, T-Mobile, and Verizon
Wireless Alliance, LLC filed Case No. 2:23-cv-00096 in the Eastern District of Texas on March 7, 2023, asserting three patents — US9144106B2, US9565662B2, and US10045383B2 — against T-Mobile and T-Mobile USA, Inc. The asserted patents cover methods for separated uplink and downlink connections and carrier management in LTE carrier aggregation environments, technologies foundational to 4G/LTE network performance across virtually all major U.S. carriers.
On December 23, 2024, the court granted a Joint Motion to Dismiss filed by Wireless Alliance and Defendants including AT&T Mobility LLC, AT&T Services, Inc., AT&T Corp., T-Mobile USA, Inc., and Cellco Partnership d/b/a Verizon Wireless, as well as intervenors Nokia and Ericsson. All claims and counterclaims were dismissed with prejudice, meaning Wireless Alliance is permanently barred from re-asserting the same claims against these defendants on these patents. Each party was ordered to bear its own costs.
The simultaneous resolution of parallel suits against AT&T, T-Mobile, and Verizon — together with Nokia and Ericsson as intervenors — is consistent with a broad industry-wide settlement, though the public record does not disclose specific financial terms. The involvement of network equipment manufacturers Nokia and Ericsson as intervenors suggests the dispute implicated standardised LTE technology, which may have added complexity and leverage to negotiations. The 657-day duration reflects meaningful pre-trial litigation activity before the parties reached resolution.

Dismissed with prejudice: what the joint motion means for both parties
Dismissal with prejudice forecloses re-filing on these patents
A dismissal with prejudice is a final adjudication on the merits for res judicata purposes. Wireless Alliance cannot re-file infringement claims against any of the named defendants — T-Mobile, AT&T, or Verizon — based on US9144106B2, US9565662B2, or US10045383B2. The joint nature of the motion indicates both sides agreed to the terms, distinguishing this from a unilateral capitulation by either party.
Permanent bar on re-filingWireless Alliance exits with claims extinguished across all three carriers
By agreeing to dismissal with prejudice, Wireless Alliance permanently relinquishes its infringement claims against T-Mobile, AT&T, and Verizon on the three asserted patents. The public record does not disclose whether a financial settlement was reached. Each party bearing its own costs is neutral on its face but is consistent with a negotiated exit rather than a plaintiff concession. The patents themselves remain in force unless separately challenged.
Claims extinguished; terms undisclosedT-Mobile and co-defendants secure permanent release from these patent claims
T-Mobile USA, AT&T, and Verizon each obtained a with-prejudice dismissal, providing certainty that Wireless Alliance cannot revisit these LTE carrier aggregation and uplink/downlink patents in future litigation against them. Nokia and Ericsson, as intervenors, also received dismissal of any counterclaims. The own-costs order avoids additional financial exposure from fee-shifting, consistent with a mutually agreed resolution.
Full release secured across carriersCoordinated resolution signals structured LTE patent licensing activity
The simultaneous dismissal of parallel suits against all three major U.S. carriers, plus Nokia and Ericsson as intervenors, is consistent with a coordinated licensing resolution rather than isolated capitulation. For the broader LTE ecosystem, this outcome suggests the asserted patents carried sufficient weight to warrant engagement by major operators and infrastructure vendors. Companies operating LTE networks or deploying carrier aggregation technology should monitor the patent family for continued enforcement activity.

Official order — verbatim text
The court’s order grants the Joint Motion to Dismiss in full, extinguishing all claims and counterclaims with prejudice. The explicit inclusion of intervenors Nokia and Ericsson in the dismissal is notable — it confirms that infrastructure vendors obtained the same finality as the carrier defendants. The own-costs provision is consistent with a negotiated resolution where neither side conceded liability. The phrase ‘cases have been resolved’ in the motion suggests an underlying agreement exists, though its terms are not part of the public record.
US9144106B2, US9565662B2 & US10045383B2 — LTE carrier aggregation methods
The three asserted patents — US9144106B2, US9565662B2, and US10045383B2 — cover methods for managing separated uplink and downlink connections and carrier aggregation in mobile communication systems. Carrier aggregation is a core LTE-Advanced (4G) and 5G NR feature that combines multiple frequency bands to increase throughput and spectral efficiency. The application lineage spans 2013 to 2017, placing the inventions squarely in the period of LTE-Advanced standardisation and commercial rollout. These patents address radio resource management and connection architecture at the air interface level.
Carrier aggregation and uplink/downlink separation are foundational to LTE and 5G network operation — virtually every major U.S. operator and network infrastructure vendor implements these techniques. That Wireless Alliance was able to bring consolidated actions against T-Mobile, AT&T, and Verizon simultaneously, and draw Nokia and Ericsson into the proceedings as intervenors, is consistent with patents that read on widely-deployed, standard-adjacent technology. For any company deploying LTE or 5G NR with carrier aggregation features, this patent family warrants careful monitoring for continuation and continuation-in-part activity.
Should your team run an FTO against US9144106B2, US9565662B2, and US10045383B2?
Any organisation deploying LTE-Advanced or 5G NR carrier aggregation — including network operators, RAN vendors, chipset manufacturers, and device OEMs — should assess freedom-to-operate against this patent family. The with-prejudice dismissal protects only the named defendants. Third parties, including MVNOs, private LTE operators, and non-U.S. carriers deploying these network features, remain fully exposed. Continuation patents stemming from the same priority chain may extend the enforcement surface beyond the three patents litigated here.

What this case signals for the LTE and wireless carrier aggregation IP landscape
The simultaneous resolution against three major carriers and two OEMs in E.D. Texas reflects patterns worth tracking for any LTE or 5G network operator.
E.D. Texas remains a high-activity venue for wireless standard-essential patent suits
The Eastern District of Texas continues to attract patent assertion entities targeting LTE and 5G infrastructure. The Wireless Alliance consolidated action — spanning T-Mobile, AT&T, and Verizon — illustrates how a single PAE can generate simultaneous multi-defendant exposure. Carriers and network vendors should maintain active monitoring of new filings in E.D. Texas against similarly-situated defendants.
Intervenor participation by Nokia and Ericsson signals standardised technology at issue
When infrastructure OEMs seek to intervene in carrier-level infringement suits, it typically signals that the asserted patents implicate standard-essential or near-standard technology embedded in vendor equipment. This dynamic can affect indemnification obligations and shifts negotiating leverage. Companies relying on vendor-supplied LTE equipment should review indemnification provisions in their supply agreements in light of cases like this one.
Wireless v T-Mobile — key questions answered
Wireless Alliance, LLC filed suit against T-Mobile USA in the Eastern District of Texas on March 7, 2023, asserting three LTE carrier aggregation patents. On December 23, 2024, all claims were dismissed with prejudice by joint motion, alongside parallel suits against AT&T and Verizon. Each party was ordered to bear its own costs.
Wireless Alliance asserted US9144106B2, US9565662B2, and US10045383B2. These patents cover methods for separated uplink and downlink connections and carrier management in LTE carrier aggregation environments — technologies central to LTE-Advanced network operation.
A dismissal with prejudice permanently bars Wireless Alliance from re-filing the same infringement claims against T-Mobile based on the three asserted patents. T-Mobile obtained a final resolution with no ongoing liability exposure to Wireless Alliance under these specific patents. The public record does not disclose whether a financial settlement was part of the agreement.
Nokia and Ericsson’s intervention is consistent with the asserted patents implicating technology embedded in vendor-supplied network equipment. Intervenors typically seek to protect their own interests — such as defending indemnification obligations or challenging patent validity — when their products are central to the accused functionality. Both were included in the with-prejudice dismissal.
The joint motion states the cases ‘have been resolved,’ which is consistent with an underlying settlement agreement. However, specific financial terms are not disclosed in the public court record. The simultaneous dismissal of parallel suits against all three major U.S. carriers, plus Nokia and Ericsson, suggests a coordinated industry-wide resolution rather than individual capitulations.
