Troy Wilson v. TPK Inc.: Synthetic Turf Removal Patent Dismissed With Prejudice
Troy Wilson asserted US10117386B1 — a patent covering a synthetic turf removal attachment for skid steers — against TPK Inc. in the Western District of Pennsylvania. After 1,963 days of litigation, the parties reached a settlement and jointly stipulated to dismissal with prejudice, with the court retaining jurisdiction to enforce the settlement agreement.
A five-year patent dispute over turf removal technology ends in settlement
Troy Wilson filed suit on May 17, 2019 in the U.S. District Court for the Western District of Pennsylvania (Case No. 1:19-cv-00146), asserting infringement of US10117386B1 — a patent covering a synthetic turf removal attachment designed for use with a skid steer loader. The defendant, TPK Inc., was represented by The Farneth Law Group, while Wilson retained The Webb Law Firm PC. Judge Marilyn J. Horan presided over the proceedings throughout their duration.
The case concluded on September 30, 2024, when Judge Horan entered an order pursuant to a stipulation of dismissal jointly filed by the parties. All claims and counterclaims — notably including those against SMG Equipment LLC, an entity named in the final order — were dismissed with prejudice. Dismissal with prejudice means Wilson cannot re-assert the same claims against the same parties in future proceedings. Critically, the court preserved federal jurisdiction to enforce the underlying settlement agreement, a provision that signals the resolution included negotiated financial or licensing terms.
The case ran for approximately 1,963 days — roughly five and a half years — before resolution, a duration that suggests the parties likely engaged in substantial discovery or claim construction proceedings before reaching terms. The public record does not disclose the financial or licensing details of the settlement. The reference to SMG Equipment LLC in the dismissal order, rather than TPK Inc. alone, may indicate a corporate restructuring or successor entity relationship that emerged during the proceedings, though the record available does not confirm this definitively.

Dismissed with prejudice by stipulation: what the order means for both parties
Stipulated dismissal with prejudice signals a negotiated exit
A stipulated dismissal with prejudice arises when both parties jointly ask the court to close the case on agreed terms. ‘With prejudice’ is the key qualifier: it bars the plaintiff from re-filing the same patent claims against the same defendants. Combined with the court’s retained jurisdiction to enforce the settlement, this structure is a hallmark of a confidential settlement agreement rather than a unilateral walk-away.
Rule 41(a)(1)(A)(ii) dismissalWilson surrenders the right to re-litigate but likely extracted value
By agreeing to dismissal with prejudice, Troy Wilson permanently closed this litigation pathway against TPK Inc. and SMG Equipment LLC. However, the court’s explicit retention of jurisdiction to enforce settlement terms strongly suggests Wilson secured consideration — likely a royalty, lump-sum payment, or licensing arrangement — that justified closing the case. The patent itself, US10117386B1, remains valid and enforceable against third parties not party to this action.
Settlement with enforcement backstopDefendant achieves finality but accepts court oversight of settlement
The with-prejudice dismissal provides TPK Inc. and SMG Equipment LLC with certainty that Wilson cannot resurrect these specific infringement claims. However, by consenting to the court retaining federal jurisdiction, the defendants accepted that any breach of the settlement agreement can be adjudicated directly in federal court without requiring a new lawsuit. This is a standard but consequential concession in patent settlements.
Finality with compliance riskUS10117386B1 remains a live risk for other synthetic turf equipment makers
This settlement does not affect the enforceability of US10117386B1 against any party other than those named in the stipulation. Competitors manufacturing or distributing synthetic turf removal attachments for skid steers should treat this patent as actively asserted. Wilson’s willingness to litigate for over five years and the court’s involvement in settlement enforcement suggest he is a motivated enforcer — a signal worth noting for any product team operating in the turf maintenance equipment space.

Official order — verbatim text
The order tracks the language of the parties’ stipulation precisely, dismissing ‘all claims and counterclaims’ with prejudice. Notably, the operative defendant named is SMG Equipment LLC rather than TPK Inc., the party of record — a discrepancy the public docket does not fully explain but which may reflect a mid-case entity change. The court’s retention of jurisdiction to enforce settlement terms is a deliberate structural choice, converting the settlement into a judicially-supervised obligation and providing the plaintiff a rapid enforcement mechanism without re-litigation.
US10117386B1 — Synthetic Turf Removal Attachment for Skid Steer
US10117386B1 is a U.S. utility patent covering a synthetic turf removal attachment engineered for skid steer loaders — the compact, wheeled or tracked vehicles used extensively in landscaping, construction, and athletic field maintenance. The patent, filed under application number US13/923298, claims a specialized mechanical attachment enabling skid steers to lift, roll, or strip synthetic turf from underlying substrates. Synthetic turf removal is a technically distinct process from installation, and dedicated attachments that interface with the skid steer’s hydraulic coupling system represent a narrow but commercially valuable product category.
The commercial significance of this patent lies in the growing market for synthetic turf replacement — driven by aging athletic fields, environmental concerns about infill materials, and municipal upgrade cycles. A patent covering an efficient removal attachment sits at a supply-chain chokepoint: contractors, municipalities, and sports facility operators all require this capability, and a patented approach with no FTO clearance creates direct infringement exposure for any competing attachment manufacturer. The five-year enforcement effort by Wilson against TPK/SMG Equipment suggests real revenue was at stake, making this patent a credible ongoing enforcement threat in the sports and landscaping equipment sector.
Should your product team run an FTO against US10117386B1?
Any company designing, manufacturing, distributing, or importing a synthetic turf removal attachment compatible with skid steer loaders should treat US10117386B1 as a priority FTO target. The patent holder has demonstrated a clear willingness to enforce — a five-year litigation campaign resulting in a court-supervised settlement is not the profile of a passive patentee. R&D teams developing competing attachment designs should assess whether their product falls within the patent’s independent claims before committing to tooling or market launch.
PatSnap Eureka’s FTO Search Agent can map the claim scope of US10117386B1 against your product specification, surface relevant prior art that could support a design-around or validity challenge, and identify the prosecution history amendments that define the patent’s enforceable boundaries. For product teams already in the market, an infringement opinion grounded in Eureka’s claim-charting tools provides documented good-faith evidence that can limit willful infringement exposure if Wilson pursues further enforcement actions.

A five-year enforcement campaign ending in a court-supervised settlement underscores the commercial seriousness of this niche but defensible patent.
Court-retained jurisdiction raises the stakes for settlement compliance
When a district court retains jurisdiction to enforce a settlement, any alleged breach can be brought before the same judge without filing a new action. For defendants in patent settlements, this means the litigation risk does not fully disappear at dismissal — it converts into ongoing compliance exposure. In-house teams should calendar all settlement obligations accordingly.
US10117386B1 is an active enforcement asset against non-settling parties
This dismissal resolves only the claims between Wilson, TPK Inc., and SMG Equipment LLC. The patent survives intact. Any company making, using, selling, or importing a competing synthetic turf removal attachment for skid steers should conduct a targeted FTO analysis against US10117386B1 before bringing product to market or continuing current operations.
Wilson v TPK — key questions answered
The case was dismissed with prejudice on September 30, 2024, pursuant to a joint stipulation of dismissal filed by the parties. The court retained federal jurisdiction to enforce the terms of the underlying settlement agreement. The dismissal covered all claims and counterclaims, with the final order naming SMG Equipment LLC as the settling defendant.
US10117386B1 is a U.S. utility patent covering a synthetic turf removal attachment for skid steer loaders. Troy Wilson, the patent holder, alleged that TPK Inc. infringed this patent — likely through manufacture, sale, or distribution of a competing attachment product. The specific infringing acts alleged are not detailed in the available public record.
The case was filed against TPK Inc., but the dismissal order identifies SMG Equipment LLC as the settling defendant. The public record does not fully explain this discrepancy. It may reflect a corporate name change, successor-in-interest relationship, or a separate related entity. Parties conducting due diligence on either company should investigate the corporate relationship between TPK Inc. and SMG Equipment LLC.
No. A with-prejudice dismissal by stipulation does not affect the patent’s validity or its enforceability against third parties. US10117386B1 remains an active, enforceable patent. Only the claims between Wilson and the settling defendants — TPK Inc./SMG Equipment LLC — are resolved. Competing manufacturers of synthetic turf removal attachments remain potential targets for future infringement actions.
When a federal court retains jurisdiction to enforce a settlement agreement, any party alleging a breach of that agreement can return to the same court without filing a new lawsuit. The court can issue orders compelling compliance, awarding damages, or taking other enforcement action. This provision protects both parties: the patent holder can enforce payment or licensing obligations, while the defendant can seek clarification of its obligations — all before Judge Horan without starting fresh litigation.
