Case Overview

The Parties

The Patent at Issue

This landmark case involved U.S. Patent No. 10,215,273 (“the ‘273 Patent”), covering a shift cable repair kit with bushing technology. The patent has been in full force and effect since issuance.

• • US 10,215,273 — Shift cable repair kit with bushing technology

The Accused Products

The defendants allegedly manufactured, sold, offered for sale, and imported into the United States a “Shift Cable Repair Kit with Bushing.” These products were identified specifically through eBay listings (305818490791 and 186153323345), highlighting the increasingly common battleground of third-party e-commerce platforms in patent enforcement actions.

Legal Representation

Plaintiffs were represented by attorney Mitchel Doriano Den Tuinder of Macfarlane, Ferguson & McMullen PA. No defendant counsel appears on record, which is a significant procedural detail.

Litigation Timeline and Procedural History

Case No. 4:25-cv-01174 was filed in the United States District Court for the Southern District of Texas, with Chief Judge Lee H. Rosenthal presiding. The Southern District of Texas is an established venue for patent litigation, and venue was established under 28 U.S.C. § 1400(b).

The 89-day resolution is notably fast by patent litigation standards, where cases routinely extend 18 to 36 months. The speed here is attributable almost entirely to the parties’ agreement to resolve through a consent judgment rather than contested litigation. No claims construction proceedings, summary judgment briefing, or trial record exists in this matter — the case moved directly from filing to negotiated resolution.

The absence of defendant counsel on record suggests the defendants either engaged in direct settlement negotiations without independent representation or chose not to formally contest the claims. The consent judgment itself notes that defendants were advised to consult counsel and confirmed they had the opportunity to do so before executing the agreement.

The Verdict & Legal Analysis

Outcome: Consent Judgment and Permanent Injunction

On June 9, 2025, the court entered a Consent Judgment and Permanent Injunction resolving all claims. This constitutes a final judgment on the merits for purposes of res judicata, collateral estoppel, issue preclusion, and claim preclusion under paragraph 8 of the order.

No specific monetary damages amount is disclosed in the available case record. The resolution focused on injunctive relief as the primary remedy.

Scope of the Permanent Injunction

The injunction is sweeping in its reach. Defendants — along with their officers, agents, servants, employees, representatives, assigns, and all persons in active concert with them — are permanently barred from:

• Manufacturing, distributing, selling, marketing, advertising, or promoting any goods infringing the ‘273 Patent
• Engaging in any activity constituting unfair competition with plaintiffs
• Aiding or abetting any third party in violating the injunction terms

Operational deadlines embedded in the order are particularly noteworthy:

• Five business days from entry: Defendants must remove all infringing product listings
• Thirty days from entry: Defendants must serve a written compliance report on plaintiffs’ counsel detailing how they have satisfied the injunction

The listing removal deadline directly targets the eBay storefronts identified in the complaint, effectively cutting off defendants’ commercial sales channel within one week of judgment.

Infringement Findings

The court acknowledged — by consent — that defendants directly infringed the ‘273 Patent under 35 U.S.C. § 271 through unauthorized commercial manufacture, use, importation, offer for sale, and sale of the shift cable repair kits within the United States. The finding covers the full scope of § 271(a) infringement activity.

Plaintiffs established that, as a direct and proximate result of defendants’ infringing conduct, they sustained substantial, immediate, and irreparable injury sufficient to support permanent injunctive relief.

Defendants’ Waiver of Appeal Rights

Paragraph 7 of the consent judgment includes a complete waiver of appellate rights. Defendants waived any and all rights to appeal, making this resolution fully final and foreclosing reconsideration at the Fifth Circuit level absent extraordinary circumstances.

Enforcement Mechanism

The court retained jurisdiction to enforce the consent judgment. Contempt of the injunction exposes defendants to sanctions, additional damages, attorneys’ fees, costs, and any further relief the court deems appropriate — creating strong post-judgment compliance incentives.
