TurboCode LLC v. Coolpad Group Ltd. — Dismissed With Prejudice After 117 Days
TurboCode LLC asserted US6813742B2 against Coolpad Group Ltd. across 23 smartphone product lines in the Eastern District of Texas. Before Coolpad filed any answer or summary judgment motion, TurboCode voluntarily dismissed the case with prejudice — a final, irrevocable termination of its infringement claims.
Pre-Answer Dismissal With Prejudice: TurboCode Ends Its Own Claim Permanently
On February 13, 2025, TurboCode LLC filed suit against Coolpad Group Ltd. in the Eastern District of Texas before Judge Rodney Gilstrap, asserting infringement of US6813742B2. The complaint targeted 23 Coolpad smartphone models ranging from the Coolpad Legacy and Coolpad Defiant to the Coolpad Cool series and Coolpad Note series, suggesting a broad claim covering core device functionality.
The case ended on June 10, 2025, when TurboCode filed a Notice of Dismissal with Prejudice under Federal Rule of Civil Procedure 41(a)(1). Because Coolpad had not yet answered the complaint or moved for summary judgment, TurboCode was entitled to file a unilateral voluntary dismissal. The court acknowledged and accepted the dismissal, and ordered each side to bear its own litigation costs — leaving no monetary award on record for either party.
The 117-day lifespan and pre-answer exit suggest the dispute was resolved — or abandoned — quickly after the complaint was filed, though the public record does not disclose whether a private settlement influenced the decision to dismiss. Critically, a dismissal with prejudice forecloses TurboCode from re-filing the same infringement claims against Coolpad on this patent, making this a strategically significant exit rather than a procedural pause.

Dismissed with prejudice: what the Rule 41(a)(1) exit means for both parties
Rule 41(a)(1) allows unilateral dismissal before defendant answers
Under Federal Rule of Civil Procedure 41(a)(1), a plaintiff may voluntarily dismiss an action without a court order by filing a notice before the defendant serves an answer or a motion for summary judgment. TurboCode exercised this right here. The ‘with prejudice’ designation, however, goes beyond the default — it permanently bars TurboCode from reasserting the same claims against Coolpad on US6813742B2.
Rule 41(a)(1) — voluntary, pre-answerWith prejudice means these claims cannot be refiled
A dismissal with prejudice operates as a final adjudication on the merits, even without a trial. Unlike a without-prejudice dismissal — which preserves the plaintiff’s right to refile — this outcome permanently extinguishes TurboCode’s infringement claims against Coolpad based on US6813742B2. TurboCode cannot refile this action in this or any other court on the same patent and the same accused products.
Claims permanently extinguishedCoolpad exits without admitting infringement or paying damages
Coolpad Group Ltd. never filed an answer, meaning no invalidity defenses, claim construction positions, or non-infringement arguments are on record. The court’s cost order — each party bears its own fees — means Coolpad recovered no attorneys’ fees despite the plaintiff’s exit. However, the with-prejudice dismissal provides Coolpad with a permanent shield against TurboCode re-asserting these specific claims on this patent.
No damages, no admissionPre-answer resolution leaves patent validity untested
Because the case ended before any substantive litigation, US6813742B2 has not been challenged, construed, or adjudicated in this proceeding. Its validity and scope remain untested, which may be relevant for other smartphone manufacturers whose products share technical characteristics with the 23 accused Coolpad models. Companies operating in the same product space should note that the patent remains enforceable.

Official order — verbatim text
The court’s order is procedural rather than substantive — it acknowledges and accepts TurboCode’s unilateral Rule 41(a)(1) notice without evaluating the merits of the infringement claims. The ‘with prejudice’ designation is the critical element: it transforms a plaintiff-initiated exit into a permanent bar on re-litigation of these claims. The cost order — each party bears its own fees — is standard for pre-answer voluntary dismissals and does not imply any finding of bad faith or exceptional case status under 35 U.S.C. § 285.
US6813742B2 — the asserted patent in TurboCode v. Coolpad
US6813742B2, filed under application number US09/681093, is a granted US utility patent asserted by TurboCode LLC against Coolpad’s smartphone portfolio. The breadth of accused products — 23 models spanning budget through premium tiers — is consistent with a patent covering foundational mobile device functionality rather than a narrow hardware feature. The patent’s application filing predates the modern smartphone era, suggesting it may cover a method or system architecture that has become embedded in mainstream device design.
From a strategic standpoint, the fact that TurboCode targeted 23 distinct Coolpad SKUs signals confidence in broad claim coverage across device categories. Any competitor manufacturing smartphones with overlapping technical architectures — particularly in the mid-range Android segment — should assess exposure to US6813742B2 independently. The absence of any IPR challenge or claim construction ruling in this case means the patent’s scope has not been publicly narrowed, maintaining its full enforcement potential against third parties.
Should your team run an FTO against US6813742B2?
Product and R&D teams developing smartphones or mobile communication devices — particularly in the Android mid-range segment — should consider a freedom-to-operate analysis against US6813742B2. The 23-product accusation in this case suggests TurboCode reads the patent’s claims broadly. If your device portfolio overlaps technically with any of the accused Coolpad models, the absence of a court ruling or IPR decision means you cannot rely on this litigation to clear your path.
PatSnap Eureka’s FTO Search Agent can map your product’s technical features against the claim language of US6813742B2, identify prior art that could support an invalidity argument, and surface any related continuation or family patents that may extend the enforcement risk. Running this analysis now — before a notice letter arrives — is significantly more cost-effective than reactive litigation in E.D. Texas.

What this case signals for the smartphone patent enforcement landscape
A pre-answer dismissal with prejudice in E.D. Texas typically signals either a quiet settlement or a tactical retreat — and the distinction matters for Coolpad competitors.
Pre-answer exits in E.D. Texas often mask confidential settlements
When a plaintiff voluntarily dismisses with prejudice before the defendant has even answered, it frequently suggests that a resolution — financial or otherwise — was reached privately. The public record is silent on any settlement terms here, but the pattern is consistent with a negotiated exit. IP teams tracking TurboCode’s licensing activity should monitor for similar filings against other smartphone OEMs.
US6813742B2 remains a live enforcement risk for smartphone manufacturers
The patent was never challenged in this proceeding. No IPR was filed, no claim construction occurred, and no invalidity arguments are on record. Any smartphone OEM whose products implement similar technical functionality to the 23 accused Coolpad models should treat this patent as an active risk and consider a freedom-to-operate review before Coolpad’s resolution is misread as a general clearance.
TurboCode v Coolpad — key questions answered
A dismissal with prejudice permanently extinguishes TurboCode’s infringement claims against Coolpad on US6813742B2. TurboCode cannot refile the same action in any court. This is distinct from a without-prejudice dismissal, which would have preserved the right to refile. The dismissal was entered under Rule 41(a)(1) because Coolpad had not yet answered or moved for summary judgment.
The public record does not disclose a settlement. The case was terminated via a plaintiff-filed Notice of Dismissal with Prejudice, with the court ordering each party to bear its own costs. This pattern — a pre-answer voluntary dismissal with prejudice — is consistent with a privately negotiated resolution, but no settlement terms have been made public in case filings.
TurboCode asserted US6813742B2 (application no. US09/681093) against 23 Coolpad smartphone models, including the Coolpad Legacy, Coolpad Defiant, Coolpad Cool series, Coolpad Note series, Coolpad Mega series, and several others. The breadth of accused products suggests the patent may cover broadly implemented mobile device functionality.
The case ended without any ruling on validity or infringement, leaving US6813742B2 fully intact as an enforcement asset. Other Android smartphone OEMs with products sharing technical characteristics with the accused Coolpad models cannot rely on this case for clearance. The patent remains available for assertion against third parties, and no IPR proceeding has been identified that would narrow or invalidate its claims.
Plaintiff TurboCode LLC was represented by David R. Bennett and Steven Kalberg. No defendant attorneys are listed in the public record, consistent with Coolpad not having filed a formal appearance before the case was dismissed. The case was assigned to Judge Rodney Gilstrap in the Eastern District of Texas.
