Cardtek International v. Starbucks: Payment Convergence Patents Dismissed Without Prejudice
Cardtek International, Inc. filed an infringement action against Starbucks Corporation in the Texas Eastern District Court, asserting three patents covering payment convergence systems and methods. The member case was dismissed without prejudice after 388 days, with each party bearing its own costs — while the lead case (2:23-cv-00045) remained open.
Payment Convergence IP Clash Ends Without Merits Ruling in E.D. Tex.
Cardtek International, Inc., holder of three patents covering payment convergence systems and methods, filed suit against Starbucks Corporation on May 15, 2023, in the U.S. District Court for the Eastern District of Texas (Case No. 2:23-cv-00217). The asserted patents — US7039593B2, US10628818B2, and US8600770B2 — relate to integrated payment processing technology, a domain directly relevant to Starbucks’ widely-used mobile and loyalty payment infrastructure.
The member case was resolved by joint stipulation filed by both parties, which the court accepted on June 6, 2024. The court dismissed all claims and causes of action without prejudice, with each side bearing its own legal costs. Notably, the stipulation was reportedly filed in the wrong member case, yet the court accepted it and directed the clerk to close Case 2:23-cv-00217 while maintaining the lead case (2:23-cv-00045) as open — suggesting the broader dispute between these parties may not be fully resolved.
The 388-day duration before resolution, combined with the ‘without prejudice’ dismissal and the existence of a still-open lead case, suggests either an interim settlement of this specific action or a strategic procedural step rather than a final resolution of the underlying IP dispute. The public record does not disclose whether any licensing arrangement or monetary consideration accompanied the dismissal, leaving the ultimate commercial outcome between Cardtek and Starbucks uncertain.

Dismissed without prejudice: what the joint stipulation means for both parties
Joint stipulation triggers dismissal without prejudice
A dismissal without prejudice via joint stipulation means the court has not adjudicated the merits of Cardtek’s infringement claims. The parties mutually agreed to end this member case, and the court accepted their stipulation under the applicable procedural rules. Critically, ‘without prejudice’ preserves Cardtek’s right to re-file the same claims in a future action, subject to applicable statutes of limitations.
No merits rulingWithout prejudice: claims survive for potential re-filing
A dismissal without prejudice is meaningfully different from one with prejudice. With prejudice permanently bars the plaintiff from reasserting the same claims; without prejudice does not. Here, the stipulation explicitly states dismissal without prejudice, meaning Cardtek retains the legal right to re-assert US7039593B2, US10628818B2, and US8600770B2 against Starbucks in a future proceeding, though practical and strategic factors may still constrain that option.
Re-filing right preservedLead case 2:23-cv-00045 remains open — dispute unresolved
The court’s order explicitly directed the clerk to maintain lead case 2:23-cv-00045 as open while closing this member case. This procedural structure — common in E.D. Tex. for consolidated or related matters — suggests the underlying dispute between Cardtek and Starbucks was not fully extinguished. Parties and counsel monitoring the broader litigation should track the lead case for further developments.
Lead case still activeEach party bears its own costs — no prevailing party designated
The court’s order that each party bear its own costs, expenses, and attorneys’ fees is consistent with a negotiated resolution rather than a litigated outcome. In U.S. patent litigation, cost-shifting to the opposing party typically requires a finding of exceptionality under 35 U.S.C. § 285. The mutual cost-bearing arrangement here typically signals that neither party conceded a decisive advantage at the time of dismissal.

Official order — verbatim text
The court’s acceptance of the joint stipulation is a procedural disposition, not a merits ruling. The language ‘DISMISSED WITHOUT PREJUDICE’ confirms that no finding on infringement, validity, or enforceability of the three asserted patents was made. The explicit instruction to maintain lead case 2:23-cv-00045 as open is legally significant — it indicates this member case closure is likely part of a broader, still-evolving litigation posture rather than a full resolution of Cardtek’s patent enforcement campaign against Starbucks.
US7039593B2, US10628818B2 & US8600770B2 — Payment Convergence Systems
The three patents at issue — US7039593B2, US10628818B2, and US8600770B2 — collectively cover systems and methods for payment convergence, a technology domain encompassing the integration of multiple payment modalities (card, mobile, loyalty, digital wallet) into unified transaction processing infrastructure. Filed across application numbers US10/217903, US14/095731, and US11/381099, these patents span a technology lineage that predates modern mobile payment ubiquity, potentially giving them broad claim scope relative to current implementations.
For large-scale retail and foodservice operators, payment convergence patents carry particular strategic weight. Starbucks operates one of the most-used mobile payment and loyalty applications in the U.S. retail sector, making it a commercially logical enforcement target. The assertion of three patents simultaneously suggests Cardtek views its portfolio as covering multiple layers of payment convergence architecture — a strategy that raises the cost and complexity of invalidity challenges and increases licensing negotiation leverage.
Should your payment platform team run an FTO against these three patents?
Any company operating a consumer-facing payment system that integrates loyalty rewards, mobile wallets, stored value, or multi-tender checkout flows should treat US7039593B2, US10628818B2, and US8600770B2 as active FTO priorities. This is particularly true for retail chains, QSR operators, fintech platforms, and payment processors whose systems process convergent tender types in a unified flow — the core technical territory these patents appear to cover.
PatSnap Eureka’s FTO Search Agent enables R&D and IP teams to map claim scope across all three patents simultaneously, identify prior art that may affect validity, and benchmark claim language against your own product architecture. With a lead case still open in E.D. Tex., the window for proactive clearance analysis is now — before a licensing benchmark is set by judicial or negotiated outcome.

What this case signals for the payments technology IP landscape
This dismissal without prejudice, alongside an open lead case, suggests ongoing IP pressure on payment platform operators in E.D. Tex.
Payment convergence patents remain a live enforcement vector
The three patents asserted — covering payment convergence systems and methods — signal that legacy payment IP portfolios are being actively monetised against major consumer-facing platforms. Fintech and retail companies with proprietary payment infrastructure should treat this case as a marker of ongoing enforcement risk in this technology class.
E.D. Tex. remains a preferred venue for payment technology assertions
Cardtek’s choice of the Eastern District of Texas is consistent with broader plaintiff-side strategy in patent licensing disputes. Companies operating consumer payment systems nationwide should monitor E.D. Tex. filings as an early signal of incoming assertions, particularly where a lead case structure suggests a portfolio-level campaign.
Cardtek v Starbucks — key questions answered
Cardtek asserted three patents: US7039593B2, US10628818B2, and US8600770B2, all covering payment convergence systems and methods. The case was filed in the Eastern District of Texas on May 15, 2023, and dismissed without prejudice on June 6, 2024.
The parties filed a joint stipulation of dismissal, which the court accepted. The dismissal was without prejudice, meaning no merits determination was made and Cardtek retains the legal right to re-assert its payment convergence patents against Starbucks in a future proceeding.
No. The court explicitly maintained lead case 2:23-cv-00045 as open while closing member case 2:23-cv-00217. This suggests the broader dispute between Cardtek and Starbucks over payment convergence patents was not fully resolved by this dismissal.
The court ordered each party to bear its own costs, expenses, and attorneys’ fees. No prevailing party was designated, and no fee award under 35 U.S.C. § 285 was made. This cost allocation is consistent with a negotiated or interim resolution rather than a litigated outcome.
These three Cardtek patents cover payment convergence systems and methods — technology relevant to any platform integrating mobile payments, loyalty programs, stored value, or multi-tender checkout. Their assertion against Starbucks signals active monetisation of legacy payment convergence IP, and companies operating similar infrastructure should consider freedom-to-operate analysis.
