AML IP v. Barnes & Noble: Token E-Commerce Patent Suit Ends in 99 Days
AML IP, LLC asserted US7328189B2 — a patent covering token-based electronic commerce systems — against Barnes & Noble in the Western District of Texas. The case resolved in 99 days via joint stipulation of dismissal with prejudice under Rule 41(a)(1)(A)(ii), with each party bearing its own fees and costs.
Token patent assertion against Barnes & Noble collapses in under 100 days
On May 12, 2025, AML IP, LLC — a patent assertion entity represented by Ramey LLP — filed suit against Barnes & Noble, Inc. in the Western District of Texas, asserting infringement of US7328189B2. The patent claims systems, products, and services that facilitate electronic commerce using tokens, a technology directly relevant to Barnes & Noble’s online retail and digital content platforms.
On August 18, 2025, just 99 days after filing, the parties submitted a joint stipulation of dismissal with prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). The court granted the request on August 19, 2025 and ordered the clerk to close the action. Critically, each party was ordered to bear its own fees and costs — a fee-neutral resolution that is consistent with a pre-trial settlement or licensing agreement reached between the parties.
The sub-100-day resolution is notably rapid for a patent infringement action in the Western District of Texas, suggesting the parties reached an understanding early in the litigation — likely before any substantive motion practice. The with-prejudice designation bars AML IP from refiling the same claims against Barnes & Noble. Whether a license was exchanged or the assertion was simply abandoned is not disclosed in the public record.

99 days — resolved faster than the W.D. Tex. median for patent infringement actions
Dismissed with prejudice: what the joint stipulation means for both parties
Rule 41(a)(1)(A)(ii): automatic dismissal on joint stipulation
Under FRCP 41(a)(1)(A)(ii), a plaintiff may dismiss an action by filing a stipulation signed by all appearing parties. As the court noted — citing Yesh Music v. Lakewood Church — such stipulations require no judicial approval and are effective automatically upon filing. The court’s order is largely ministerial, directing the clerk to close the docket.
No merits adjudicationWith prejudice: AML IP’s claims are permanently extinguished
A dismissal with prejudice operates as a final judgment on the merits, barring AML IP from re-asserting the same claims under US7328189B2 against Barnes & Noble in any future action. This is the most conclusive form of voluntary dismissal available, and it binds the plaintiff regardless of whether consideration changed hands. By contrast, a dismissal without prejudice would leave the door open for refiling.
Claims permanently barredBarnes & Noble exits with prejudice and no fee liability
Barnes & Noble, defended by Quinn Emanuel Urquhart & Sullivan, secured a with-prejudice dismissal — meaning AML IP cannot reassert these token e-commerce claims against the company. The fee-neutral cost order means Barnes & Noble absorbs its own defense costs, which is typical in stipulated dismissals and does not necessarily signal weakness in either party’s position.
Full resolution, no fee awardPAE token patent assertions face stiff early resistance in W.D. Tex.
This outcome is consistent with a pattern in which patent assertion entities pursuing broad e-commerce token claims encounter early pushback from well-resourced defendants. The engagement of Quinn Emanuel — a firm associated with aggressive patent defense — suggests Barnes & Noble was prepared to contest validity and infringement vigorously. Early resolution may reflect a licensing payment, but the public record does not confirm this.

Official order — verbatim text
The court’s order reflects a purely procedural resolution — no claim construction, infringement finding, or validity ruling was issued. The with-prejudice designation is the substantively significant element: it transforms a consensual dismissal into a bar against future assertion of the same claims. The fee-neutrality order is standard for Rule 41(a)(1)(A)(ii) stipulations and does not indicate which party was in a stronger litigation position. The absence of any cost award to Barnes & Noble confirms this was not adjudicated as an exceptional case under 35 U.S.C. § 285.
US7328189B2 — token-based electronic commerce systems
US7328189B2 (application no. US09/753784) covers systems, products, and services that facilitate electronic commerce using tokens. Token-based transaction architectures are foundational to modern e-commerce, underpinning payment tokenisation, digital gift cards, loyalty reward systems, and session authentication flows. The patent’s application date — suggested by the serial number format — indicates filing in the early-to-mid 2000s, placing it in the formative era of online retail infrastructure.
The commercial significance of US7328189B2 lies in its potential breadth across any platform that issues or processes tokens to enable a purchase or digital transaction. This implicates not only traditional retailers with online storefronts like Barnes & Noble, but also digital content marketplaces, subscription platforms, and payment intermediaries. For competitors and adjacent technology companies, the patent represents a non-trivial assertion risk — particularly given its assertion by an NPE with no product to defend against counterclaims.
Should you run an FTO analysis against US7328189B2?
Any company operating an e-commerce platform that issues, validates, or redeems tokens — whether for payments, digital content access, gift cards, or loyalty programmes — should assess its exposure to US7328189B2. The patent has now been asserted in at least one W.D. Texas action. AML IP’s willingness to file against a major retailer like Barnes & Noble signals that no defendant is considered too prominent to target.
PatSnap Eureka’s FTO Search Agent can map your product’s token transaction flows against the independent claims of US7328189B2, identify relevant prior art that could support an IPR petition, and flag claim elements that may require design-around consideration. For in-house IP teams, running this analysis proactively — before a demand letter arrives — is significantly more cost-effective than reactive litigation defence.

What this case signals for the e-commerce patent IP landscape
Token-based e-commerce patents remain active assertion tools, but the Barnes & Noble result illustrates how quickly these cases can resolve when defendants engage elite counsel early.
W.D. Texas remains a venue of choice for PAE token patent assertions
AML IP’s choice of the Western District of Texas follows a well-established pattern for patent assertion entities. Despite post-TC Heartland venue scrutiny, W.D. Tex. continues to attract e-commerce patent cases. Companies with online retail operations should monitor their venue exposure and ensure they can establish a credible challenge to personal jurisdiction or proper venue if targeted.
With-prejudice outcomes offer defendants durable protection from repeat assertions
The with-prejudice dismissal is Barnes & Noble’s most commercially valuable outcome — it permanently forecloses AML IP from re-asserting US7328189B2 against the company. Defendants in PAE cases should always negotiate for prejudice terms when settling, rather than accepting a without-prejudice dismissal that leaves the door open for a second round of litigation costs.
AML v Barnes — key questions answered
The case was dismissed with prejudice by joint stipulation on August 19, 2025, 99 days after filing. Under FRCP 41(a)(1)(A)(ii), the parties filed a signed stipulation of dismissal and the court ordered the clerk to close the action. Each party bears its own fees and costs. The with-prejudice designation permanently bars AML IP from re-asserting the same claims against Barnes & Noble.
US7328189B2 covers systems, products, and services that facilitate electronic commerce using tokens. Barnes & Noble operates both a physical retail network and digital content platforms that likely involve token-based transaction or authentication mechanisms. As an NPE, AML IP can assert the patent without exposure to counterclaims based on its own products, making online retailers a logical assertion target.
A dismissal with prejudice operates as a final judgment on the merits, permanently extinguishing AML IP’s right to re-file the same claims under US7328189B2 against Barnes & Noble. It is more protective for the defendant than a without-prejudice dismissal, which would allow refiling. The with-prejudice outcome here may reflect a negotiated resolution, though no financial terms are disclosed in the public record.
The Western District of Texas — particularly the Waco and Austin divisions — has been a preferred venue for patent assertion entities due to its historically plaintiff-friendly procedural environment and experienced patent docket. Ramey LLP, which represented AML IP, has filed numerous cases in this district. Since the Supreme Court’s TC Heartland decision, venue choice for NPEs has narrowed, but W.D. Tex. remains viable where defendants have a regular and established place of business.
The public record does not disclose whether any consideration changed hands. Fee-neutral cost orders are standard in Rule 41(a)(1)(A)(ii) stipulated dismissals and do not confirm or deny the existence of a licensing payment or settlement amount. The rapid 99-day resolution and the engagement of Quinn Emanuel on the defence side are consistent with, but do not prove, a negotiated commercial resolution.
