Ministrap v. Walmart: Secure Strap Patent Suit Dismissed After 515 Days
Ministrap LLC brought a patent infringement action against Walmart Inc. in the Eastern District of Texas, asserting three secure strap system patents. After 515 days of litigation, the parties filed a joint motion to dismiss — with Ministrap’s infringement claims dismissed with prejudice and Walmart’s counterclaims dismissed without prejudice.
A three-patent strap system suit ends in asymmetric dismissal
Ministrap LLC filed suit against Walmart Inc. on July 14, 2023, in the Eastern District of Texas, asserting infringement of three U.S. patents — US8371000B1, US9386824B1, and US7587796B1 — all covering secure strap systems. The case was docketed as member case No. 2:23-cv-00331-JRG-RSP, suggesting it formed part of a broader consolidated litigation campaign by Ministrap in the same district.
The case closed on December 10, 2024, via a joint motion to dismiss. The court granted the motion, dismissing all of Ministrap’s infringement claims with prejudice — meaning those specific claims cannot be re-filed — while Walmart’s counterclaims and defenses were dismissed without prejudice, leaving Walmart’s positions legally preserved for any future proceedings. Each party was ordered to bear its own costs, attorneys’ fees, and expenses, with all pending relief denied as moot.
At 515 days, the case ran longer than many E.D. Texas patent matters that resolve by mutual dismissal, suggesting substantive litigation activity occurred before the parties reached resolution. The asymmetric dismissal structure — with prejudice for plaintiff, without prejudice for defendant — is a pattern consistent with a negotiated resolution in which the plaintiff agrees to permanently relinquish its claims. The public record does not disclose whether any settlement consideration was exchanged.

Joint dismissal with asymmetric prejudice: what the order means for each party
Dismissed with prejudice bars Ministrap from re-filing these claims
A dismissal with prejudice is a final adjudication on the merits for claim-preclusion purposes. By agreeing to this structure, Ministrap permanently forfeited the right to reassert these specific infringement claims against Walmart based on the three asserted patents. This is the most defendant-favorable outcome short of a judgment of non-infringement or invalidity.
Claim preclusion appliesMinistrap loses enforcement rights against Walmart on these patents
With prejudice dismissal of Ministrap’s claims means the three asserted patents — US8371000B1, US9386824B1, and US7587796B1 — can no longer be enforced against Walmart for the conduct at issue. Ministrap retains the patents and may pursue third-party infringers, but Walmart is effectively shielded from future action under the same claim set. The no-costs order suggests neither side extracted a fee award.
Patents intact; Walmart enforcement barredWalmart’s counterclaims preserved — without prejudice exit is strategically valuable
Walmart’s counterclaims and defenses were dismissed without prejudice, meaning they were not adjudicated and remain legally available. This asymmetry is notable: Walmart retains the option to raise invalidity or other defenses in a future context, such as if the patents are asserted against Walmart affiliates or in related proceedings. Without prejudice exit from counterclaims is a commercially significant concession from Ministrap.
Counterclaims legally preservedAsymmetric dismissal signals likely negotiated resolution with undisclosed terms
The with/without prejudice split, combined with a mutual no-costs order and joint motion, is structurally consistent with a confidential settlement. For competitors in secure strap and restraint system markets, the patents remain active and enforceable against third parties. Companies sourcing or distributing similar strap products should note that Ministrap has demonstrated willingness to litigate and negotiate, and that these three patents have not been invalidated.

Official order — verbatim text
The court’s order reflects a textbook asymmetric joint dismissal: Ministrap’s infringement claims are extinguished with finality under claim preclusion doctrine, while Walmart’s counterclaims — including any invalidity defenses — exit without prejudice and remain legally viable. The explicit denial of all pending relief as moot confirms no substantive merits rulings were made. The mutual no-costs provision is consistent with a negotiated resolution, as fee-shifting under 35 U.S.C. § 285 was not pursued by either side.
US8371000B1, US9386824B1 & US7587796B1 — Secure Strap Systems
The three patents asserted in this case — US8371000B1 (App. No. 12/548377), US9386824B1 (App. No. 13/765168), and US7587796B1 (App. No. 11/670829) — all relate to secure strap systems, a technology category covering fastening, restraint, and attachment mechanisms. The sequential application numbers suggest a portfolio developed over time, with the earliest application number corresponding to US7587796B1, indicating a foundational invention that was later built upon through continuation or related filings.
For the retail and hardware distribution sector, this patent portfolio is strategically significant. Walmart’s position as a major distributor of consumer and commercial strap products made it a high-visibility enforcement target. The fact that all three patents survived litigation without a validity challenge reaching judgment means competitors manufacturing or selling secure strap products — including tie-downs, cargo straps, and restraint systems — face ongoing exposure. Any product incorporating strap fastening mechanisms that could read on these claims warrants a formal FTO review.
Should you run an FTO against US8371000B1, US9386824B1 & US7587796B1?
If your company manufactures, imports, or retails secure strap systems, tie-down straps, cargo restraints, or similar fastening products, these three Ministrap patents represent a direct and unresolved risk. None were invalidated in this proceeding. Ministrap has demonstrated a structured, multi-defendant enforcement approach in E.D. Texas — meaning any product in the strap and restraint category could be a future assertion target.

Portfolio viewWhat this case signals for the secure strap and restraint system IP landscape
Ministrap’s multi-defendant campaign in E.D. Texas shows a structured enforcement approach — and this dismissal pattern has practical implications for retail and hardware supply chains.
With prejudice exit confirms Walmart’s exposure is resolved — third parties remain at risk
The prejudice asymmetry in this dismissal is the key signal. Ministrap’s claims against Walmart are extinguished, but the three patents are alive and unadjudicated on validity. Any competitor or retailer in the secure strap or tie-down market should treat these patents as active enforcement risks until expressly challenged or expired.
E.D. Texas member case structure suggests a broader coordinated campaign
The ‘member case’ designation indicates this was part of a consolidated multi-defendant action in the Eastern District of Texas — a common NPE litigation strategy. Parties facing similar assertions from Ministrap in related cases should monitor the parent docket for developments that may affect claim scope, scheduling, or settlement leverage.
The no-costs order masks likely undisclosed settlement consideration
Mutual no-costs orders in jointly dismissed E.D. Texas patent cases frequently accompany confidential cash or licensing settlements. The 515-day duration and joint motion filing pattern are consistent with a negotiated exit rather than a pure walkaway — meaning Walmart may have paid a license fee that is not publicly disclosed.
Invalidity arguments remain untested — IPR window may still be open
None of the three asserted patents — US8371000B1, US9386824B1, US7587796B1 — were adjudicated on validity. Depending on filing dates and IPR petition timelines, inter partes review may remain an available route for parties seeking to neutralise these patents before facing their own infringement action.
Ministrap v Walmart — key questions answered
The court granted a joint motion to dismiss, dismissing all of Ministrap’s infringement claims with prejudice and Walmart’s counterclaims without prejudice. Each party bears its own costs. The order was entered December 10, 2024, after 515 days of litigation in the Eastern District of Texas.
Ministrap’s infringement claims were dismissed with prejudice, meaning they are permanently extinguished and cannot be re-filed against Walmart. Walmart’s counterclaims were dismissed without prejudice, meaning they were not adjudicated and remain legally available for future proceedings. This asymmetry is the defining feature of the outcome.
Ministrap asserted three patents: US8371000B1 (App. No. 12/548377), US9386824B1 (App. No. 13/765168), and US7587796B1 (App. No. 11/670829). All three relate to secure strap systems. None were adjudicated on validity or infringement — the case ended by joint dismissal.
No. A dismissal with prejudice in this context extinguishes Ministrap’s claims against Walmart specifically — it is not a ruling on patent validity or infringement merits. The three asserted patents remain in force and may still be enforced against other parties who have not been dismissed or licensed.
The docket designation as a ‘member case’ (2:23-cv-00331-JRG-RSP) is consistent with consolidated multi-defendant litigation in the Eastern District of Texas. This structure is commonly used by patent assertion entities targeting multiple defendants with the same patent portfolio. Related member cases may remain active or have separate resolution timelines.
