Wolverine Barcode IP v. Amazon.com — Dismissed Without Prejudice in 7 Days
Wolverine Barcode IP, LLC filed suit against Amazon.com in the Western District of Texas on July 30, 2025, asserting US9280689B2 — a patent covering methods and apparatus for offline commerce transactions. The case ended just seven days later when plaintiff voluntarily dismissed without prejudice before Amazon filed any responsive pleading.
A seven-day patent suit: barcode commerce IP vs. Amazon
On July 30, 2025, Wolverine Barcode IP, LLC — a patent assertion entity holding US9280689B2 — filed an infringement action against Amazon.com, Inc. in the Western District of Texas before Judge David Counts. The asserted patent, US9280689B2 (application no. US13/816955), claims methods and apparatus for conducting offline commerce transactions, a technology area relevant to barcode-enabled purchasing and point-of-sale systems.
On August 4, 2025 — five days after filing — plaintiff filed a Notice of Voluntary Dismissal Without Prejudice under Federal Rule of Civil Procedure 41(a)(1)(A)(i). Because Amazon had not yet served an answer or a motion for summary judgment, the notice was self-effectuating: the court’s August 6 order confirmed closure but required no substantive ruling. Each party was ordered to bear its own costs, expenses, and attorney fees.
A seven-day lifespan is notably brief even by the standards of quick-exit patent filings in W.D. Tex. The absence of any responsive pleading from Amazon suggests the dismissal preceded any substantive engagement, which may indicate early settlement negotiations, a strategic re-filing decision, or a filing made in anticipation of a licensing conversation. The public record is silent on the underlying commercial rationale.

Voluntarily dismissed: what the Rule 41 exit means for both parties
Rule 41(a)(1)(A)(i): self-effectuating dismissal, no court order needed
Under Fed. R. Civ. P. 41(a)(1)(A)(i), a plaintiff may dismiss an action without a court order by filing a notice before the defendant serves an answer or motion for summary judgment. Because Amazon had not responded, Wolverine’s notice was self-effectuating — the Fifth Circuit has confirmed such notices ‘terminate the case in and of itself.’ The court’s order merely directed the clerk to close the docket.
No merits adjudicatedWithout prejudice: Wolverine retains the right to re-file
The notice expressly states dismissal without prejudice, meaning no final judgment on the merits was entered and Wolverine Barcode IP is not barred from asserting US9280689B2 against Amazon again in a future action. This distinguishes the outcome from a dismissal with prejudice, which would extinguish the claims permanently. The public record does not disclose whether any licensing agreement or covenant-not-to-sue was exchanged as part of the exit.
Re-filing remains possibleAmazon exits without liability — but patent threat persists
Amazon faces no court-imposed liability, injunction, or damages finding. The without-prejudice dismissal means Amazon did not secure a ruling on invalidity or non-infringement of US9280689B2. The patent remains active and enforceable, and Wolverine retains freedom to reassert. Amazon received no declaratory judgment of non-infringement, leaving its long-term exposure to this specific patent unresolved.
No invalidity ruling securedShort-cycle filings signal licensing pressure, not full litigation
Cases dismissed within days of filing — before any responsive pleading — are consistent with patent assertion strategies designed to initiate licensing dialogue rather than pursue trial. The cost-neutral outcome (each party bears its own fees) suggests no settlement payment was court-ordered, though private arrangements are not disclosed. Companies in the barcode, offline payments, and e-commerce checkout space should monitor US9280689B2 for continued enforcement activity.

Official order — verbatim text
The court’s order confirms the dismissal was procedurally uncontested: Amazon had not filed an answer or motion for summary judgment, making Wolverine’s Rule 41(a)(1)(A)(i) notice self-effectuating by operation of law. The court’s language — citing In re Amerijet — underscores that no judicial discretion was exercised on the merits. The without-prejudice designation means US9280689B2 survives as an enforceable assertion vehicle, and neither validity nor infringement was tested.
US9280689B2 — Method and apparatus for offline commerce transactions
US9280689B2, filed under application number US13/816955, claims a method and apparatus for conducting offline commerce transactions. The patent sits within the intersection of barcode technology and commerce infrastructure — covering systems that enable purchase or transaction processing without a continuous network connection, likely leveraging barcode or similar machine-readable identifiers. The granted patent number (B2 designation) indicates it issued with amended claims following USPTO examination.
For the e-commerce and retail technology sector, this patent represents a potentially broad claim over offline or intermittent-connectivity transaction methods — a capability embedded in scan-and-go retail, kiosk checkout, and mobile point-of-sale systems. Amazon’s extensive physical and digital retail infrastructure makes it a commercially logical assertion target. Any company operating barcode-based offline payment or purchase systems should assess whether their implementation falls within the claim scope of US9280689B2, particularly given the without-prejudice dismissal leaves Wolverine free to assert again.
Should you run an FTO analysis against US9280689B2?
If your product or platform involves barcode-enabled offline commerce — including scan-and-go retail, offline POS terminals, mobile checkout without connectivity, or kiosk-based purchasing — US9280689B2 warrants a freedom-to-operate review. The patent’s assertion against Amazon suggests the owner is actively monitoring large-scale implementers, and a without-prejudice dismissal means enforcement activity could resume or shift to other defendants at any time.
PatSnap Eureka’s FTO Search Agent can map the claim language of US9280689B2 against your specific product architecture, identify prior art that may support invalidity arguments, and surface related patents in Wolverine Barcode IP’s portfolio. Proactive FTO analysis now is significantly less costly than reactive litigation defence — especially given Ramey LLP’s track record of serial filings in the Western District of Texas.

What this case signals for the offline commerce patent IP landscape
A seven-day voluntary dismissal in W.D. Tex. rarely signals the end of a patent assertion campaign — it often signals a reset.
Without-prejudice dismissals preserve full re-filing rights against the same defendant
Wolverine Barcode IP retains the ability to re-assert US9280689B2 against Amazon in any competent jurisdiction. Companies that receive a patent complaint and see it withdrawn without prejudice should not treat the exit as resolution — the underlying IP risk remains live until the patent expires, is invalidated, or a covenant-not-to-sue is granted.
W.D. Tex. remains a favoured venue for short-cycle patent assertion filings
The Western District of Texas continues to attract patent assertion entity filings, including cases that resolve before any responsive pleading. Defendants and their counsel should maintain readiness for rapid procedural responses even in cases that appear to close quickly, and should track docket activity for follow-on filings in other venues.
Wolverine v Amazon.com — key questions answered
The case was dismissed without prejudice. Plaintiff filed a Rule 41(a)(1)(A)(i) notice on August 4, 2025, expressly specifying dismissal without prejudice. This means no final judgment on the merits was entered, and Wolverine Barcode IP retains the right to reassert US9280689B2 against Amazon in a future action.
US9280689B2 (application no. US13/816955) is a granted US patent claiming a method and apparatus for conducting offline commerce transactions. The patent covers systems enabling purchase or transaction processing — likely using barcode or machine-readable identifiers — without requiring continuous network connectivity. It is relevant to scan-and-go retail, offline POS, and kiosk checkout implementations.
The public record does not disclose the commercial reason. The plaintiff filed a voluntary dismissal notice before Amazon served any responsive pleading, which is consistent with early settlement negotiations, a licensing conversation, or a strategic decision to re-file in a different venue or against a different defendant. The court’s order was purely procedural and offers no insight into the underlying rationale.
Yes. Because the dismissal was without prejudice, no res judicata bar was established. Wolverine Barcode IP may reassert US9280689B2 against Amazon in any competent court, subject to applicable statutes of limitations and the patent’s remaining enforceability period. Amazon did not obtain a declaratory judgment of non-infringement or invalidity in this proceeding.
Wolverine Barcode IP was represented by William P. Ramey III of Ramey LLP, a Texas-based firm with an extensive track record of patent infringement filings on behalf of non-practising entities in the Western District of Texas. No defendant counsel of record appeared before the dismissal was filed.
