2BCOM LLC v. TCL Technology Group: 7-Patent Wireless Suit Dismissed With Prejudice
2BCOM, LLC brought a seven-patent infringement action against TCL Technology Group and five affiliated entities in the Eastern District of New York, targeting wireless communication and mobile terminal technologies. After 538 days of litigation, 2BCOM voluntarily dismissed all claims with prejudice — permanently extinguishing its right to re-assert those patents against TCL.
Seven wireless patents, six TCL entities, one final exit
On 11 November 2022, 2BCOM, LLC filed suit in the Eastern District of New York against TCL Technology Group Corp. and five related TCL entities — TCL Communication Technology Holdings, TCL Communication Ltd., TCL Electronics Holdings, TCT Mobile International, and TCT Mobile Worldwide — asserting infringement of seven US patents covering wireless communication systems, mobile terminal access, data transfer over radio networks, user authentication, and battery-reporting for external storage devices.
On 2 May 2024, 2BCOM filed a Rule 41(a)(1)(A)(i) notice voluntarily dismissing the entire action with prejudice against all six TCL defendants. Each side bears its own attorneys’ fees, costs and expenses. A dismissal with prejudice is a final adjudication on the merits as a matter of law, meaning 2BCOM is permanently barred from bringing the same claims against the same TCL entities on these seven patents.
At 538 days, the case ran longer than many voluntarily dismissed patent suits, suggesting the parties engaged in substantive pre-trial activity — potentially including claim construction briefing, early discovery, or licensing negotiations — before 2BCOM elected to exit on terms that included no cost recovery. The commercial rationale and any confidential settlement or licensing arrangement that may have preceded the dismissal are not reflected in the public record.

Voluntarily dismissed with prejudice: what Rule 41 means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s unilateral exit — but permanent
A Rule 41(a)(1)(A)(i) notice allows a plaintiff to dismiss before the defendant files an answer or motion for summary judgment, requiring no court order. Here, however, 2BCOM expressly stipulated dismissal WITH prejudice — converting a procedurally simple exit into a final, merits-equivalent termination. Courts treat a with-prejudice dismissal as a judgment on the merits, triggering res judicata on the dismissed claims.
Final on the meritsWith prejudice: 2BCOM’s claims are permanently extinguished
Unlike a without-prejudice dismissal — which preserves the right to refile — a with-prejudice dismissal permanently bars 2BCOM from asserting these seven patents against the TCL defendants in any future action. The public record confirms the with-prejudice designation explicitly. No re-filing option remains on these claims against these parties. This outcome is materially more favourable to TCL than a typical voluntary dismissal.
No refile permitted2BCOM exits with no recovery and no future leverage against TCL
2BCOM received no documented monetary recovery, no injunctive relief, and absorbed its own legal costs. The with-prejudice designation forecloses any future enforcement action against the named TCL entities on these patents. Whether a confidential licensing arrangement or cross-deal preceded the dismissal is not disclosed in the public record, but the absence of a cost award suggests a negotiated exit rather than a capitulation under litigation pressure alone.
No documented recoveryTCL obtains permanent bar — stronger position than a simple dismissal
For TCL and its five affiliates, the with-prejudice dismissal provides full res judicata protection against these seven patents from this plaintiff. TCL bears its own costs but gains a permanent shield against any future 2BCOM action on the same IP. Companies operating in the wireless communication and mobile terminal space who watch TCL’s litigation posture will note that a well-resourced multi-entity defence appeared to deter 2BCOM from pursuing its claims through trial.

Official order — verbatim text
The dismissal notice expressly invokes Rule 41(a)(1)(A)(i) and specifies the with-prejudice designation for all six TCL defendants, with each side bearing its own costs. This precise phrasing carries significant legal weight: the with-prejudice qualifier elevates what is procedurally a simple plaintiff notice into a final disposition on the merits, conferring res judicata protection on TCL. The equal costs allocation suggests neither party conceded wrongdoing or litigation misconduct, consistent with a negotiated resolution rather than a court-ordered outcome.
US6831444B2 and 6 co-asserted patents — wireless communication and mobile terminal systems
The seven asserted patents — US6831444B2, US6885643B1, US6982970B2, US7460477B2, US6928166B2, US7876736B2, and US7251237B2 — span core wireless communication technologies including mobile terminal access architectures enabling simultaneous connectivity to both mobile and local networks, transport-layer protocol execution over radio networks, user authentication in radio communication devices, and battery status notification for external storage. These are foundational wireless infrastructure patents filed across application numbers dating to the early 2000s, covering technologies that underpin modern smartphone and cellular device operation.
For any OEM or chipset vendor operating in the wireless communication or mobile device space, the breadth of this portfolio is strategically significant. The patents cover layers from authentication and data transfer protocols through to hardware-level communication device integration — technologies embedded in virtually every contemporary mobile handset. TCL, as a major global mobile OEM under brands including Alcatel and BlackBerry Mobile, represented a high-value enforcement target. The portfolio’s scope suggests 2BCOM may pursue similar claims against other mobile device manufacturers not covered by this dismissal.
Should you run an FTO against US6831444B2 and the 2BCOM wireless portfolio?
Any company designing, manufacturing, or distributing mobile handsets, wireless communication modules, radio network equipment, or mobile operating software should assess exposure to this seven-patent portfolio. The dismissed action against TCL does not limit 2BCOM’s ability to assert these patents against other parties. Products incorporating simultaneous dual-network connectivity, transport-layer radio protocols, or device-level user authentication are squarely within the claimed technology space.
PatSnap Eureka’s FTO Search Agent can map each of the seven asserted patent numbers against your product architecture, identify claim elements that overlap with your technology, surface prior art that may support invalidity arguments, and flag related continuations or family members in 2BCOM’s portfolio that could form the basis of future enforcement. A structured FTO now is substantially cheaper than litigation defence later.

What this case signals for the wireless communication IP landscape
A seven-patent wireless suit ending in a with-prejudice dismissal after 538 days carries clear lessons for mobile IP enforcement and defence strategy.
Multi-entity TCL defence structure created significant litigation friction
Six named defendants — spanning holding companies, communication units and mobile divisions — required 2BCOM to maintain infringement theories across a complex corporate family. Three defence law firms (Merchant & Gould, Pillsbury Winthrop, Taft) and six defence counsel suggest a well-resourced, coordinated response that likely drove up plaintiff’s cost exposure substantially.
With-prejudice exit after 538 days signals a negotiated resolution, not collapse
Voluntary dismissals with prejudice and no cost award at the 538-day mark typically suggest a confidential commercial resolution — whether a licensing agreement, cross-licence, or portfolio deal — rather than a plaintiff abandoning unmeritorious claims. The public record is silent on terms, but the timeline and fee structure are consistent with a negotiated outcome.
2BCOM v TCL — key questions answered
The with-prejudice dismissal under Rule 41(a)(1)(A)(i) permanently bars 2BCOM from asserting the seven patents against the named TCL entities in any future action. It operates as a final adjudication on the merits via res judicata. However, the dismissal does not affect 2BCOM’s ability to assert the same patents against other, non-TCL defendants in separate proceedings.
2BCOM asserted seven US patents: US6831444B2, US6885643B1, US6982970B2, US7460477B2, US6928166B2, US7876736B2, and US7251237B2. The patents cover wireless communication systems, mobile terminal dual-network access, transport-layer radio protocols, electronic apparatus communication, external storage battery notification, wireless data transfer methods, and radio device user authentication.
The public record does not specify 2BCOM’s precise venue rationale. E.D.N.Y. filings by patent licensors typically reflect defendant business contacts, registered agent locations, or product sales within the district. TCL’s US commercial presence through device sales would likely satisfy venue and personal jurisdiction requirements in E.D.N.Y.
Six TCL-affiliated entities were named: TCL Technology Group Corp. (lead defendant), TCL Communication Technology Holdings Ltd., TCL Communication Ltd., TCL Electronics Holdings Ltd., TCT Mobile International Ltd., and TCT Mobile Worldwide Ltd. The multi-entity structure reflects TCL’s complex holding company architecture and is a common plaintiff strategy to capture the full corporate family.
The stipulation that each party bears its own attorneys’ fees, costs, and expenses is consistent with a negotiated commercial resolution rather than a litigation victory for either side. Had 2BCOM simply abandoned unmeritorious claims, defendants might have sought fee awards under 35 U.S.C. § 285. The absence of any fee award, combined with the 538-day timeline, suggests a structured exit, potentially involving undisclosed licensing or commercial terms.
