C47 Technologies v. TCL Technology: Dismissed with Prejudice After 451 Days
C47 Technologies LLC filed suit against TCL Technology Group and three affiliated entities in the Eastern District of Texas, asserting US10984605B2 against TCL’s 10, 20, and 30 Series consumer electronics lines. The parties jointly stipulated to dismiss all claims with prejudice after 451 days, each bearing their own costs — a resolution consistent with a negotiated settlement outside the public record.
Patent assertion against TCL’s consumer electronics lines ends quietly in E.D. Texas
On June 4, 2024, C47 Technologies LLC — a patent assertion entity represented by Garteiser Honea PLLC — filed an infringement action in the Eastern District of Texas (Judge Rodney Gilstrap) against TCL Technology Group Corporation and three co-defendants: TCL Communication Technology Holdings Limited, TCL Electronics Holdings Limited, and TCT Mobile (US) Inc. The complaint asserted US10984605B2 against TCL’s 10 Series, 20 Series, and 30 Series product lines, representing a broad swath of TCL’s mid-range consumer electronics portfolio.
The case resolved on August 29, 2025, when the parties filed a Joint Stipulation of Dismissal with Prejudice pursuant to Rule 41 of the Federal Rules of Civil Procedure. Judge Gilstrap accepted the stipulation and closed the case, directing each party to bear its own costs and fees. Dismissal with prejudice is a final adjudication on the merits for procedural purposes — C47 Technologies is permanently barred from re-asserting the same claims against these TCL entities in any federal court.
At 451 days, the case resolved considerably faster than typical E.D. Texas patent matters that proceed to trial, suggesting the parties reached a private resolution — likely a license or covenant not to sue — before substantive motion practice concluded. The ‘own costs’ provision neither signals a clear-cut win for either side nor implies an exceptional-case finding under 35 U.S.C. § 285. The precise financial terms, if any, remain confidential and outside the public record.

Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41 dismissal with prejudice operates as a final judgment
A joint stipulation of dismissal with prejudice under Rule 41(a)(1)(A)(ii) is self-executing once filed and accepted by the court. It functions as a final adjudication on the merits, meaning C47 Technologies cannot re-file the same patent claims against these TCL defendants in any federal forum. Judge Gilstrap’s order confirms the dismissal and closes the docket — no further proceedings are possible absent extraordinary circumstances.
Permanent bar on re-filingC47 Technologies loses all future enforcement leverage against TCL
By agreeing to dismiss with prejudice, C47 Technologies permanently surrenders its right to pursue these specific claims against the named TCL entities. In practice, PAEs in this position typically accept a confidential licence or lump-sum payment in exchange. The ‘own costs’ provision suggests neither party extracted a fee-shifting advantage, which is consistent with a commercially negotiated exit rather than a litigation defeat on the merits.
Likely confidential licenceTCL secures certainty — no further exposure on US10984605B2 from this plaintiff
The with-prejudice dismissal gives all four TCL entities a clean exit from this specific suit. TCL’s 10, 20, and 30 Series products are shielded from further claims under US10984605B2 by C47 Technologies. K&L Gates’ involvement suggests TCL mounted a credible defence posture. However, US10984605B2 remains in force and could be asserted by C47 or any future assignee against different defendants or different product lines.
Cleared for named defendants onlyPatent remains live — other TCL competitors or product lines stay at risk
The dismissal resolves only this case. US10984605B2 has not been invalidated, cancelled, or disclaimed. Competitors manufacturing similar display or interface-enabled consumer electronics should treat this patent as an active enforcement risk. PAEs frequently resolve one case to fund further assertion campaigns. Companies in the mid-range Android device space — particularly those without existing licences — should monitor C47 Technologies’ filing activity and conduct proactive FTO analysis.

Official order — verbatim text
The court’s order accepting the joint stipulation is procedurally routine but strategically significant. The ‘dismissed with prejudice’ language confirms finality — no claims survive and no appeal path exists for the plaintiff. The ‘each party shall bear its own costs’ provision is neutral on the merits; it does not reflect a § 285 exceptional-case finding. The denial of all pending relief as moot confirms no substantive rulings on claim construction, validity, or infringement were entered, leaving the patent’s enforceability against third parties entirely intact.
US10984605B2 — consumer electronics display or interface technology
US10984605B2 (application no. US17/069690) is an issued U.S. utility patent asserted against TCL’s 10 Series, 20 Series, and 30 Series product lines — a range spanning multiple generations of mid-range consumer Android devices. The breadth of products targeted in a single action suggests the patent’s claims are directed at a fundamental feature common across device generations, likely relating to display rendering, user interface interaction, or a related hardware-software integration found in modern smartphones and connected devices.
From a competitive intelligence standpoint, the simultaneous assertion against three product series signals that the patent holder believed claim language was broad enough to cover a core platform-level feature rather than a single SKU. For OEMs competing in the mid-range Android device market, this patent represents a potential read-across risk. The absence of an invalidity or non-infringement ruling means the patent’s enforceability has not been tested in any public forum, and its claims remain available for future assertion against other manufacturers.
Should your product team run an FTO against US10984605B2?
Any company designing, manufacturing, or importing mid-range consumer electronics — particularly Android smartphones, tablets, or smart displays — into the U.S. market should assess exposure to US10984605B2. C47 Technologies demonstrated willingness to pursue a major global OEM across multiple product generations simultaneously. If your products share display, interface, or connectivity features with the TCL 10/20/30 Series, a proactive freedom-to-operate analysis is warranted before you receive a demand letter.
PatSnap Eureka’s FTO Search Agent can map US10984605B2’s independent claims against your product’s feature set, surface prior art that may support an IPR petition, and identify related continuation or family applications that could represent future assertion risk. Given that no claim construction order was issued in this case, the patent’s scope remains legally untested — making early-stage FTO work especially valuable for product teams planning U.S. market entry or product line expansion.

What this case signals for the consumer electronics IP landscape
A fast-resolved E.D. Texas PAE suit against a global OEM’s core product lines carries several lessons for IP teams monitoring assertion risk.
E.D. Texas remains the default venue for PAE actions against consumer electronics OEMs
Judge Gilstrap’s docket continues to attract patent assertion entity filings against global hardware manufacturers. TCL’s presence across multiple U.S. entities made it a predictable target. Companies distributing consumer electronics through U.S. subsidiaries should maintain standing litigation readiness in E.D. Texas, where case management timelines can accelerate pressure to settle before claim construction.
Multi-entity defendant structure raises early costs but strengthens settlement posture
Naming four TCL entities — spanning the parent group, a U.S. subsidiary, and two Hong Kong-registered holding companies — is a common PAE tactic to maximise jurisdictional pressure and complicate early dismissal motions. Defendants who can coordinate across entities (as TCL did through K&L Gates) are better positioned to negotiate a unified exit and avoid serial litigation on the same patent.
C47 v TCL — key questions answered
Dismissal with prejudice in this case means all of C47 Technologies’ infringement claims under US10984605B2 against the four TCL entities are permanently terminated. C47 cannot re-file the same claims against the same defendants in any federal court. The order was entered on joint stipulation, so it reflects a negotiated exit rather than a merits adjudication.
No settlement terms have been publicly disclosed. The parties filed a Joint Stipulation of Dismissal with Prejudice under Rule 41, which the court accepted. The ‘own costs’ provision means no fee-shifting occurred. PAE cases resolved this way are commonly understood to involve a confidential licence or payment, but the public record does not confirm any financial terms.
The complaint targeted TCL’s 10 Series, 20 Series, and 30 Series lines of products — multiple generations of mid-range consumer electronics, predominantly Android smartphones and related devices sold in the U.S. market through TCT Mobile (US) Inc. and affiliated entities.
Yes. The with-prejudice dismissal only bars C47 Technologies from suing the four named TCL defendants again on the same claims. The patent was not invalidated, cancelled, or subjected to any IPR proceeding in this case. US10984605B2 remains an issued, enforceable U.S. patent and could be asserted against other manufacturers or different TCL entities in a future action.
The Eastern District of Texas, and Judge Gilstrap’s docket specifically, is a preferred venue for patent assertion entities due to its historically plaintiff-friendly procedural rules, experienced patent judges, and established case management practices. TCT Mobile (US) Inc.’s U.S. presence provides a jurisdictional nexus. E.D. Texas regularly handles a disproportionate share of U.S. patent infringement filings relative to its size.
