AML IP v. Kroger: Electronic Commerce Token Patent Dismissed With Prejudice
AML IP, LLC asserted US7177838B1 — a patent covering electronic token-based commerce transactions — against retail giant Kroger Co. in the Western District of Texas. The case closed after just 96 days when AML IP voluntarily dismissed all claims with prejudice, permanently extinguishing its right to re-assert the patent against Kroger.
Early voluntary dismissal extinguishes AML IP’s claim against Kroger
On October 24, 2024, AML IP, LLC — a non-practising entity holding US7177838B1 — filed suit against Kroger Co. in the Western District of Texas before Judge Leon Schydlower. The asserted patent covers a method and apparatus for conducting electronic commerce transactions using electronic tokens, a technology area directly relevant to loyalty programs, digital payment systems, and tokenised checkout infrastructure deployed at scale by major retailers.
On January 28, 2025, just 96 days after filing, AML IP filed a notice of voluntary dismissal under Federal Rule of Civil Procedure 41(a)(1)(A)(i) — available as of right because Kroger had neither answered the complaint nor filed a motion for summary judgment. Critically, the notice specified that dismissal is WITH PREJUDICE as to the asserted patent, meaning AML IP permanently relinquished its right to bring this specific infringement claim against Kroger again.
The speed of resolution — under 100 days, before any substantive defence filing — and the with-prejudice designation are notable. The public record does not disclose whether a confidential settlement drove the prejudice designation, or whether AML IP independently concluded the claim lacked viability. Each party bearing its own costs suggests no side extracted a financial concession on fees, though the underlying commercial terms, if any, remain private.

96 days — resolved before defendant answered or filed any substantive motion
Dismissed with prejudice: what the voluntary exit means for both parties
Rule 41(a)(1)(A)(i): plaintiff’s right to dismiss before answer
Federal Rule 41(a)(1)(A)(i) permits a plaintiff to dismiss an action without a court order by filing a notice before the defendant serves an answer or a motion for summary judgment. AML IP exercised this right on day 96. Unusually, the notice self-imposed a with-prejudice designation — Rule 41(a)(1) dismissals are otherwise without prejudice by default. This election is legally binding and forecloses future suits on the same patent against Kroger.
Voluntary, with prejudiceAML IP permanently surrenders its claim against Kroger
By electing dismissal with prejudice, AML IP cannot re-file this action or assert US7177838B1 against Kroger in any future proceeding. This is a materially stronger concession than a standard Rule 41(a)(1) without-prejudice exit. Whether a confidential settlement compensated AML IP for this surrender is not reflected in the public docket. The patent itself remains in force and may still be asserted against other defendants.
Claim extinguished vs. KrogerKroger secures permanent immunity from this patent claim
Kroger exits without having filed a single substantive pleading, achieving the strongest possible litigation outcome at minimal docketed cost. The with-prejudice designation provides Kroger with a res judicata-equivalent shield against any future assertion of US7177838B1 by AML IP. Kroger’s digital payment and loyalty token infrastructure faces no further exposure from this plaintiff on this patent. Each party bearing its own costs means Kroger absorbed its own legal fees.
Full immunity securedElectronic token patent risk persists for other retailers
US7177838B1 survives this dismissal in full force. AML IP retains the right to assert it against other retail, fintech, or e-commerce operators deploying token-based transaction architectures. The rapid, with-prejudice exit against Kroger may reflect litigation risk assessment, claim scope concerns, or a private resolution — but it does not signal the patent is invalid or unenforceable. Other companies in the electronic commerce and loyalty-token space should monitor AML IP’s enforcement activity.

Official order — verbatim text
The dismissal notice is self-executing under Rule 41(a)(1)(A)(i) and required no judicial order — the case closed by plaintiff’s unilateral filing. The explicit with-prejudice designation is the operative legal fact: it converts what would be a default without-prejudice exit into a permanent bar. The cost-sharing provision — each party bears its own fees — is standard for pre-answer dismissals and does not indicate any adjudication on the merits of the infringement claim.
US7177838B1 — Electronic commerce transactions using electronic tokens
US7177838B1 claims a method and apparatus for conducting electronic commerce transactions using electronic tokens — a framework broadly applicable to digital loyalty systems, prepaid token architectures, and tokenised payment flows. Filed under application number US09/553695, the patent predates the mainstream adoption of digital wallets and loyalty platforms, giving its claims potential reach over modern implementations of token-exchange commerce that may not have anticipated the patent’s priority date.
For the retail and fintech sectors, this patent represents a non-trivial assertion risk. Electronic token transactions underpin loyalty reward systems, gift card infrastructures, and increasingly, blockchain-adjacent digital payment schemes operated by large-scale retailers. AML IP’s willingness to assert against Kroger — one of the largest U.S. grocers with significant digital commerce operations — signals that the patent holder views the claims as commercially relevant to mainstream retail technology stacks. Other operators in this space should assess exposure proactively.
Should your product team run an FTO against US7177838B1?
Any company deploying token-based transaction systems — including digital loyalty programs, prepaid card infrastructure, tokenised checkout flows, or electronic voucher platforms — should evaluate whether US7177838B1 reads on their implementation. The fact that AML IP asserted this patent against a major U.S. retailer, and that the patent survived the litigation intact, confirms the holder regards it as commercially enforceable. R&D and product teams building or scaling electronic token commerce features face real exposure.

What this case signals for the electronic commerce IP landscape
A sub-100-day with-prejudice exit by an NPE against a major retailer carries specific signals for patent risk strategy in digital payments.
With-prejudice exits by NPEs are rare — and strategically significant
Most Rule 41(a)(1) NPE dismissals are without prejudice, preserving the option to refile. AML IP’s self-imposed with-prejudice designation is atypical and suggests either a confidential resolution or a calculated concession. Companies facing similar NPE claims should consider the leverage available before a defendant answers — at that stage, a plaintiff holds maximum unilateral dismissal power.
Retail token infrastructure remains an active patent assertion target
US7177838B1 covers a broad method for electronic commerce token transactions — squarely relevant to loyalty points, digital wallets, and tokenised checkout systems. With the patent still in force, other grocery, retail, and fintech operators using comparable architectures face credible exposure. An FTO analysis against this patent is advisable for any company scaling token-based payment infrastructure.
AML v Kroger — key questions answered
The with-prejudice dismissal means AML IP, LLC is permanently barred from asserting US7177838B1 against Kroger Co. in any future action. Unlike a without-prejudice exit, this designation functions as a final adjudication on the merits for res judicata purposes as between these specific parties. AML IP retains full rights to assert the patent against all other parties.
Rule 41(a)(1)(A)(i) grants a plaintiff an absolute right to voluntarily dismiss without a court order, provided the defendant has not yet served an answer or a motion for summary judgment. Kroger had taken neither step within the 96-day case window, so AML IP could file the notice unilaterally. The court had no discretion to deny the dismissal once the notice was filed.
Yes. A voluntary dismissal with prejudice affects only the claims between the named parties in that action. US7177838B1 remains in full force and effect. AML IP retains the right to assert it against any other company whose products or services may infringe the claims. No validity or enforceability ruling was made by the court in this case.
US7177838B1 covers a method and apparatus for conducting electronic commerce transactions using electronic tokens. Products and systems potentially at risk include digital loyalty reward platforms, prepaid and gift card processing systems, tokenised payment flows, and electronic voucher or coupon redemption architectures. Any retail or fintech operator deploying token-based transaction infrastructure should assess claim-level exposure.
