Wash World v. Belanger: $7.48M Patent Judgment Over Car Wash Lighting
Wash World filed for declaratory judgment in Wisconsin federal court seeking to invalidate Belanger’s US8602041 patent covering illuminated spray arm systems. After nearly six years of litigation, the court entered judgment for Belanger — awarding $7.48M in damages plus a permanent injunction barring Wash World’s LumenArch product line.
Declaratory judgment gamble backfires — Wash World faces $7.48M and a permanent ban
Wash World, Inc. filed this action in the Eastern District of Wisconsin on October 24, 2019, seeking a declaratory judgment of non-infringement or invalidity of US8602041 — Belanger’s patent covering illuminated lighting systems integrated into spray arms used in automated car wash equipment. The accused products centred on Wash World’s LumenArch lighting system and its integration into the Razor EDGE, Razor XR-7, and related touch-free car wash platforms.
The case closed on July 16, 2025, with Judge William C. Griesbach entering judgment on the merits in favour of Belanger. The court awarded Belanger $7,222,152 in lost profits and $260,000 in royalties — totalling $7,482,152 in compensatory damages — plus $702,317 in prejudgment interest. A permanent injunction was also entered, barring Wash World from manufacturing, selling, marketing, or importing any LumenArch product or any product not colorably different from it, running until the expiration of the ‘041 patent.
The nearly six-year duration of this case — nearly twice the national median for patent cases — suggests hard-fought claim construction and damages disputes. Wash World’s choice to initiate via declaratory judgment rather than wait to be sued may have reflected confidence in an invalidity or non-infringement position that ultimately failed to persuade the court. The public record does not disclose the specific claim construction rulings or expert testimony that drove the damages quantum, but the scale of lost profits ($7.2M) relative to royalties ($260K) suggests the court accepted Belanger’s market displacement theory.

Judgment for Belanger: what the $7.48M verdict and injunction mean
Declaratory judgment plaintiff loses on the merits
A declaratory judgment action lets a party facing potential infringement claims seek a court ruling of non-infringement or invalidity before being sued. Here, Wash World initiated the action — but the court found in Belanger’s favour on the merits, effectively confirming infringement and the patent’s validity. The judgment on the merits carries full preclusive effect, barring Wash World from relitigating the same issues.
Merits judgment — full preclusive effectBelanger secures $7.48M and a permanent market exclusion
Belanger emerges with both compensatory relief and forward-looking protection. The lost profits award of $7,222,152 signals the court accepted that Belanger lost actual sales to Wash World’s infringing LumenArch line. The permanent injunction — covering the full LumenArch product family and any colorably similar successors — effectively restores Belanger’s exclusive market position for illuminated spray arm systems until US8602041 expires.
Permanent injunction + $7.48M damagesWash World faces product exit and $8.18M liability
Wash World must immediately cease manufacturing, selling, and marketing all LumenArch products and any colorably similar variants. The injunction extends to trade show promotion, website, and social media — an unusually broad marketing bar. Combined with $8.18M in total liability (damages plus prejudgment interest), the judgment represents a material commercial setback and may affect Wash World’s ability to compete in the premium touch-free car wash segment.
Full product line enjoinedLighting-as-differentiator patents validated in car wash equipment
This outcome signals that aesthetic and experiential innovations — such as integrated lighting in spray arms — can command robust patent protection and significant lost profits recoveries in the car wash equipment sector. Competitors developing illuminated or light-integrated wash equipment should treat US8602041 as a live enforcement risk and consider FTO analysis before commercialising similar lighting configurations in spray or arch systems.

Official order — verbatim text
The judgment’s explicit enumeration of enjoined products — including the Razor EDGE, Razor XR-7, LumenArch, and retrofit kits — reflects a court intent to leave no ambiguity about scope, reducing Wash World’s ability to argue that successor products fall outside the injunction. The lost profits award of $7.2M significantly exceeds the $260K royalty component, consistent with a finding that Belanger and Wash World competed directly for the same customers. The prejudgment interest of $702,317 suggests infringement was found to have commenced well before the 2019 filing date.
US8602041 — Illuminated spray arm lighting system for car wash equipment
US8602041 (application no. US12/707777) protects a lighting system claimed in the context of spray arms and spray arm covers used in spray-type car wash systems. The patent’s claims cover both the integrated lighting architecture and the structural covers that house it — enabling both the functional and aesthetic differentiation of illuminated wash bays. The application’s filing history suggests development in the early-to-mid 2010s, positioning it squarely in the period when experiential differentiation began driving premium car wash equipment design.
From a competitive standpoint, US8602041 is strategically significant because it protects a feature — illuminated spray arms — that has become a visible differentiator in the touch-free car wash segment. The court’s willingness to award over $7M in lost profits confirms that the market treats Belanger and Wash World as direct substitutes in this category. Any manufacturer developing illuminated or light-integrated wash arches, spray arms, or retrofit lighting kits should treat this patent as a primary FTO target before commercialisation.
Should you run an FTO against US8602041 before launching illuminated car wash equipment?
If your R&D or product team is developing any spray arm, wash arch, or retrofit lighting system for automated car wash applications, US8602041 is an active enforcement risk. The Wash World verdict demonstrates that Belanger is willing and able to litigate to a permanent injunction — and that courts will award substantial lost profits where market overlap is demonstrable. This applies equally to OEM manufacturers, distributors, and companies acquiring car wash equipment assets.
PatSnap Eureka’s FTO Search Agent enables you to map the claim scope of US8602041 against your product’s technical specifications, identify prior art that may support a validity challenge, and surface design-around pathways before you commit to a product launch. Given the injunction’s ‘colorably different’ standard, a rigorous claim-by-claim FTO is strongly advisable for any lighting-integrated spray arm or arch system entering the US market.

What this case signals for the car wash equipment IP landscape
A $7.48M verdict and permanent injunction over spray arm lighting confirms that niche equipment patents carry real enforcement teeth.
Declaratory judgment carries reverse litigation risk
Filing for declaratory judgment accelerates the dispute and eliminates the option to quietly design around before suit is filed. Wash World’s proactive filing gave Belanger an early litigation platform — and ultimately a $8.18M judgment. Before filing DJ actions, companies should rigorously assess whether invalidity or non-infringement positions are robust enough to survive full merits adjudication.
Lost profits theory signals strong market overlap — monitor your competitive position
The court’s award of $7.2M in lost profits — rather than a lower royalty-only figure — suggests Belanger demonstrated it was the direct, but-for market alternative to Wash World’s LumenArch. Any competitor selling into the same automated car wash segment should assess whether their product positions them as a market substitute for Belanger’s patented lighting systems.
Wash v Belanger — key questions answered
Judgment was entered in favour of Belanger, Inc. The court awarded $7,222,152 in lost profits and $260,000 in royalties, plus $702,317 in prejudgment interest. A permanent injunction was also issued barring Wash World from manufacturing, selling, or marketing the LumenArch product line and any colorably similar products until US8602041 expires.
US8602041 protects a lighting system claimed in spray arms and spray arm covers used in spray-type car wash systems. It was central to the case because Wash World’s LumenArch product — integrated into the Razor EDGE and Razor XR-7 car wash systems — was found to infringe its claims. The patent’s scope was broad enough to support both a lost profits award and a permanent injunction.
Wash World’s filing of a declaratory judgment action suggests it anticipated that Belanger would assert US8602041 against the LumenArch product line and sought to control the litigation forum and timeline. The strategy ultimately backfired: by initiating suit, Wash World accelerated resolution on a merits basis and Belanger secured a full judgment including injunction and lost profits damages.
The injunction covers the Razor EDGE car wash system with LumenArch, the Razor and Razor XR-7 combined with LumenArch, the LumenArch standalone unit, LumenArch cover or cover segments, LumenArch retrofit kits, and any product not colorably different from the above. It also bars Wash World from promoting or advertising enjoined products online, on social media, or at trade shows.
The court awarded $7,222,152 in lost profits — indicating the court accepted Belanger’s claim that it would have made the sales Wash World captured with the LumenArch product line. An additional $260,000 in reasonable royalties was awarded, suggesting some sales were not covered by the lost profits theory. The public record does not disclose the full expert testimony or methodology, but the ratio of lost profits to royalties is consistent with a finding of strong market substitution.
