Ministrap LLC v. Best Buy: Secure Strap Patent Case Dismissed With Prejudice
Ministrap LLC filed suit against Best Buy and three affiliated entities in the Eastern District of Texas, asserting three patents covering secure strap systems. After 493 days of litigation, all of Ministrap’s infringement claims were dismissed with prejudice under a joint stipulation — permanently closing the door on those claims.
Three-Patent Strap Systems Suit Ends in Prejudicial Dismissal for Ministrap
On July 14, 2023, Ministrap LLC filed a patent infringement action in the Eastern District of Texas (Case No. 2:23-cv-00327) against Best Buy Co., Inc. and three affiliated entities — Best Buy Stores LP, BestBuy.com LLC, and Best Buy Texas.com LLC. The complaint asserted three US patents: US8371000B1, US9386824B1, and US7587796B1, all directed to secure strap systems. Best Buy is one of the largest consumer electronics retailers in the United States, and the accused products suggest the dispute centred on strapping or securing accessories sold through Best Buy’s retail and online channels.
The case closed on November 18, 2024, via a joint stipulation of dismissal filed under Federal Rule of Civil Procedure 41(a)(1)(A)(ii). Under its specific terms, Ministrap dismissed all infringement claims it raised or could have raised with prejudice — meaning those exact claims cannot be refiled. Best Buy’s counterclaims and defences, by contrast, were dismissed without prejudice, preserving their right to reassert them in future proceedings if circumstances warranted.
The 493-day duration from filing to close, combined with a with-prejudice dismissal of the plaintiff’s claims, is consistent with a negotiated resolution — potentially a licence, settlement payment, or commercial agreement — reached after substantial litigation activity but before trial. The public record does not disclose financial terms or the specific trigger for dismissal. The asymmetric dismissal terms (plaintiff with prejudice, defendants without) are a standard structural feature of settlements in patent cases and do not necessarily reflect a win or loss for either side on the merits.

With-prejudice dismissal: what the stipulation means for both parties
Rule 41(a)(1)(A)(ii): stipulated dismissal, not a court judgment
A dismissal under Rule 41(a)(1)(A)(ii) is a voluntary joint action — both parties sign and file the stipulation, and the court merely accepts it. Crucially, because Ministrap’s claims are dismissed with prejudice, the dismissal carries res judicata effect: Ministrap cannot bring the same infringement claims against these Best Buy entities in any future proceeding. No merits ruling was issued by the court.
Rule 41(a)(1)(A)(ii) stipulationWith-prejudice dismissal bars Ministrap from re-asserting these claims
Ministrap’s voluntary dismissal with prejudice is legally final as to all infringement claims it raised or could have raised against these defendants. This is the most consequential term for the patent holder: the three asserted patents remain in force, but Ministrap is permanently barred from suing the same Best Buy entities on the same patent claims. A settlement payment or licence is the most commercially rational explanation for accepting this outcome, though the public record does not confirm this.
Claims permanently extinguishedBest Buy’s counterclaims survive — dismissed without prejudice
All claims, defences, and counterclaims raised by the Best Buy defendants were dismissed without prejudice, meaning they retain the ability to revive those arguments if future litigation arises. This typically includes invalidity challenges or declaratory judgment claims. The without-prejudice treatment of defendant counterclaims is standard in settlements and preserves Best Buy’s litigation posture should Ministrap pursue related patents or related products in subsequent actions.
Counterclaims preservedSecure strap patents remain active — third-party exposure persists
The dismissal resolves only Ministrap’s dispute with Best Buy. The three asserted patents — US8371000B1, US9386824B1, and US7587796B1 — remain in force and enforceable against other parties. Retailers, manufacturers, or distributors of secure strap accessories and related securing systems operating independently of this case should assess their FTO position against this patent family. A settlement with a major retailer may signal Ministrap’s continued enforcement intent.

Official order — verbatim text
The stipulation’s language is precise and consequential: Ministrap dismissed ‘all claims of infringement that [Plaintiff] raised or could have raised’ — a broad res judicata trigger covering both asserted and potentially assertable claims against these defendants. The court’s acceptance of the stipulation is administrative rather than adjudicative; no merits finding was made. The asymmetric prejudice terms are the operative legal architecture: Ministrap’s claims are permanently extinguished as to these parties, while Best Buy retains its defensive posture intact.
US8371000B1, US9386824B1 & US7587796B1 — Secure Strap Systems
The three asserted patents — US8371000B1, US9386824B1, and US7587796B1 — are US granted patents with B1 designations, indicating they issued without any pre-grant publication (suggesting straightforward or accelerated prosecution). The application numbers span filings from application series 11, 12, and 13, suggesting a portfolio built over multiple filing generations. All three cover secure strap systems — a technology domain encompassing strapping, fastening, and securing accessories used across consumer electronics, sporting goods, and utility markets.
A three-patent portfolio asserted against a major retail channel suggests Ministrap has constructed layered IP coverage around its core strap technology — a common NPE or licensing-entity strategy. The involvement of Best Buy’s e-commerce and physical retail entities as defendants implies the accused products were sold both online and in-store. For manufacturers and distributors supplying strap-based securing products through major retail channels, this patent family represents an active enforcement risk that warrants FTO analysis before commercial launch or retail distribution agreements.
Should you run an FTO against US8371000B1, US9386824B1, and US7587796B1?
Any company designing, manufacturing, importing, or distributing secure strap systems — including tie-down straps, device straps, cargo securing accessories, or related attachment hardware — sold through US retail channels should treat this three-patent family as an active FTO concern. The with-prejudice dismissal confirms Ministrap successfully enforced this portfolio against one of the largest US retailers. If your products fall within the strap systems category and you distribute through retail or e-commerce channels in the US, an FTO analysis is warranted before scaling distribution.

What this case signals for the secure strap systems IP landscape
A with-prejudice dismissal after 16 months in E.D. Texas suggests commercial resolution — and Ministrap’s patents remain live enforcement tools.
With-prejudice dismissals in E.D. Texas frequently signal settlement
When a plaintiff voluntarily dismisses with prejudice in a patent case — especially after over a year of litigation — this pattern is strongly consistent with a negotiated commercial outcome. The terms are not public, but the structural asymmetry (plaintiff with prejudice, defendants without) is a textbook settlement construct. IP teams tracking Ministrap’s enforcement activity should note this as a resolved, not abandoned, matter.
Three-patent assertion expands infringement surface and settlement leverage
Ministrap asserted three distinct US patents against the same product category. Multi-patent assertions complicate prior art defences and raise the cost of invalidity challenges for defendants. Companies in the securing accessories or strap systems supply chain should audit their exposure to the full family, not just one patent in isolation.
Ministrap v Best — key questions answered
Ministrap LLC sued Best Buy Co. Inc. and three affiliated entities in the Eastern District of Texas asserting three patents covering secure strap systems. After 493 days, the case was dismissed via a joint stipulation under Rule 41(a)(1)(A)(ii). Ministrap’s infringement claims were dismissed with prejudice; Best Buy’s counterclaims were dismissed without prejudice.
A with-prejudice dismissal is legally final. Ministrap is permanently barred from re-filing the same infringement claims — or claims it could have raised — against the named Best Buy entities based on the same patents. The patents themselves remain valid and enforceable against third parties not party to this case.
Ministrap asserted three US patents: US8371000B1 (application no. 12/548377), US9386824B1 (application no. 13/765168), and US7587796B1 (application no. 11/670829). All three cover secure strap systems. The B1 designation on each indicates they issued without pre-grant publication.
This asymmetric structure is standard in patent case settlements. Dismissing the plaintiff’s claims with prejudice provides the defendant with finality — the lawsuit cannot be refiled. Dismissing the defendant’s counterclaims without prejudice is a concession to the plaintiff; it avoids a formal invalidity ruling on the patents. Both parties accept the asymmetry as part of the negotiated resolution.
Yes. The dismissal resolves only the dispute between Ministrap and the Best Buy entities. US8371000B1, US9386824B1, and US7587796B1 remain issued, active patents. Ministrap retains the right to assert them against other manufacturers, retailers, or distributors of secure strap products that were not party to Case No. 2:23-cv-00327.
