Apex Beam Technologies v. TCL: 5G Patent Dispute Ends in Dismissal With Prejudice
Apex Beam Technologies LLC filed suit against TCL’s multinational entity group in the Eastern District of Texas, asserting five US patents covering 5G wireless communications technology across TCL’s smartphone and tablet lineup. After 1,087 days of litigation, the parties jointly moved to dismiss with prejudice — strongly suggesting a negotiated resolution.
Five 5G Patents, Six TCL Devices, One Joint Settlement in E.D. Tex.
Apex Beam Technologies LLC, a patent assertion entity holding a portfolio of wireless communications patents, filed suit on November 30, 2021 in the Eastern District of Texas against TCT Mobile International Limited and four affiliated TCL entities. The complaint asserted five US patents — US10944527B2, US10568113B2, US10912081B2, US10462767B2, and US10951271B2 — covering 5G wireless communication technologies. The accused products included the TCL 10 5G UW, TCL 30XL, TCL 40 XL, TCL 20A 5G, TCL 20 Pro 5G, and Tab Pro 5G.
The case closed on November 21, 2024, when Judge Rodney Gilstrap granted a joint motion to dismiss with prejudice under Federal Rule of Civil Procedure 41(a)(2). The order states the parties ‘have resolved their respective claims for relief asserted in this litigation.’ Dismissal with prejudice bars Apex Beam from re-filing the same claims against the same TCL defendants, and the absence of fee-shifting suggests neither party was found to have litigated in bad faith.
The 1,087-day duration — nearly three full years — is consistent with Eastern District of Texas patent cases that proceed through substantive claim construction and discovery before settling. The joint motion and mutual cost-bearing arrangement are hallmarks of a confidential license or cross-resolution. The specific financial terms, if any, are not disclosed in the public record. Whether the resolution covers future TCL 5G product generations beyond those named in the complaint is also unknown from the public docket.
Filing to Dismissed with Prejudice in 1087 days
1,087 days — nearly three years before resolution, consistent with contested E.D. Tex. patent timelines
Dismissed with prejudice: what the joint motion outcome means for both parties
Rule 41(a)(2) dismissal with prejudice: a final, court-ordered close
A dismissal with prejudice under Rule 41(a)(2) is a final adjudication on the merits for res judicata purposes. Apex Beam cannot re-file these same five patent claims against the same TCL defendants in any US court. The joint nature of the motion — filed by both sides — signals a mutually agreed resolution rather than a unilateral surrender, and the court’s ‘claims resolved’ language confirms the parties reached agreement before filing.
Final resolution — no re-filingApex Beam exits with prejudice — but likely on agreed terms
Dismissal with prejudice normally signals the plaintiff received something of value — whether a license fee, cross-license, or other consideration — before agreeing to permanently close the case. Apex Beam forfeits any future litigation on these claims against these defendants, but the joint motion structure suggests this was a strategic exit rather than a capitulation. The public record does not disclose financial terms.
Confidential resolution likelyTCL entities released from all five patent claims permanently
All five TCL-affiliated defendants — TCT Mobile International, TCL Communication Technology Holdings, TCL Technology Group, TCL Electronics Holdings, and TCL Communication Ltd — are permanently released from Apex Beam’s five asserted 5G patents. Future enforcement on these specific patents against these entities is barred. However, the TCL group may still face exposure from other Apex Beam patents or related portfolio claims not asserted in this case.
Permanent release — five patents5G handset makers: Apex Beam’s portfolio remains active against others
The resolution of this case does not extinguish Apex Beam’s five asserted patents — they remain enforceable against third parties. Other 5G smartphone OEMs selling in the US market should consider whether their device architectures overlap with the same wireless communication methods. The Eastern District of Texas remains a preferred venue for NPE-led 5G patent enforcement, and dismissal-with-prejudice settlements typically validate the economic leverage of the asserted portfolio.

Official order — verbatim text
The court’s order closely tracks the joint motion’s language — notably that the parties ‘have resolved their respective claims for relief’ — before granting dismissal with prejudice under Rule 41(a)(2). This phrasing is legally significant: it is the court’s confirmation of a final, consensual termination rather than a merits adjudication. The with-prejudice designation carries full res judicata effect, closing these five patent claims against these defendants permanently. The denial of all pending relief as moot and the own-costs directive leave no outstanding obligations on the public record.
US10944527B2 — 5G wireless communications methods and systems
The five asserted patents — US10944527B2, US10568113B2, US10912081B2, US10462767B2, and US10951271B2 — cover wireless communication methods and systems relevant to 5G NR (New Radio) device operation. The application dates (filings from 2018–2019 based on corrected application numbers in the 15/xxx–16/xxx range) place them in the critical pre-standardization and early-standardization window for 5G, when foundational radio layer and signaling methods were being patented by both implementers and NPEs.
For OEMs building 5G-capable smartphones and tablets, this patent cluster represents the category of wireless communication method claims most frequently asserted in NPE litigation. Patents covering scheduling, transmission control, and radio resource management are difficult to design around because they track how 3GPP standards require devices to behave. Any manufacturer shipping 5G devices compliant with NR standards in the US market faces potential exposure to portfolios like Apex Beam’s, and should conduct FTO analysis against application families in the US15/xxx–US16/xxx filing cohort.
Should your 5G product team run an FTO against Apex Beam’s patent portfolio?
Any company designing, importing, or distributing 5G smartphones, tablets, or mobile broadband devices in the United States should assess exposure to the five patents asserted in this case. The accused TCL products — ranging from mid-range 5G handsets to a 5G tablet — suggest the patent claims are not limited to premium or flagship devices. If your product implements standard 5G NR radio layer functions, these patents and their family members warrant review.
PatSnap Eureka’s FTO Search Agent can map your product’s 5G feature set against Apex Beam’s full patent family, identify related continuation and divisional applications still in prosecution, and flag claim language that tracks 3GPP NR specifications. Eureka also surfaces litigation history across all five patent numbers, enabling your legal team to assess claim scope as interpreted in the E.D. Tex. proceedings before commissioning a full FTO opinion.

What this case signals for the 5G wireless patent enforcement landscape
NPE-driven 5G patent assertions in E.D. Tex. continue to resolve via confidential settlement — with multi-entity defendant structures adding jurisdictional complexity.
E.D. Tex. remains the dominant venue for 5G NPE enforcement actions
Judge Gilstrap’s docket in Marshall, Texas continues to attract 5G patent assertions against global handset OEMs. The Apex Beam case follows a well-worn pattern: NPE files multi-patent complaint against an OEM’s full 5G line, litigation runs through discovery and claim construction, and the case resolves confidentially before trial. Companies selling 5G devices in the US should maintain active docket monitoring for E.D. Tex. filings.
Multi-entity defendant structures signal jurisdictional strategy by both sides
Apex Beam named five separate TCL corporate entities as defendants — a common plaintiff-side tactic to capture the full supply and distribution chain and reduce the risk of any single entity arguing lack of jurisdiction. Defendants countered with a unified defense team. This structural complexity typically extends litigation timelines and raises the cost of defense, increasing settlement leverage for patent holders early in the case lifecycle.
Apex v TCT — key questions answered
Apex Beam asserted five US patents: US10944527B2, US10568113B2, US10912081B2, US10462767B2, and US10951271B2. All relate to 5G wireless communication methods and systems. The accused products included the TCL 10 5G UW, TCL 30XL, TCL 40 XL, TCL 20A 5G, TCL 20 Pro 5G, and Tab Pro 5G.
The case was dismissed with prejudice pursuant to a joint motion under Rule 41(a)(2), after the parties confirmed they had resolved their respective claims. Dismissal with prejudice is final — Apex Beam cannot re-assert these five patents against the same TCL entities in any US court. The joint nature of the motion strongly suggests a confidential settlement or license agreement was reached.
Five TCL-affiliated entities were named: TCT Mobile International Limited (lead defendant), TCL Communication Technology Holdings Limited, TCL Technology Group Corporation, TCL Electronics Holdings Limited, and TCL Communication Ltd. This multi-entity approach is a common plaintiff tactic to capture the full corporate chain responsible for designing, manufacturing, and distributing the accused devices.
No. The court’s dismissal order explicitly states ‘each side shall bear its own costs and fees.’ No fee-shifting award was made under 35 U.S.C. § 285 or otherwise. The mutual cost-bearing arrangement is standard in joint voluntary settlements and does not indicate that either party was found to have litigated in bad faith.
The case ran for 1,087 days from filing on November 30, 2021 to closure on November 21, 2024 — approximately three years. This duration is consistent with contested E.D. Tex. patent cases that proceed through claim construction and fact discovery before settling. Cases before Judge Gilstrap that resolve before trial typically fall in the two-to-three-year range, suggesting this case followed a standard litigation trajectory.
