This real patent litigation was adjudicated by United States District Court for the Western District of Texas, involving imported industrial hydraulic component patent infringement. The actual beneficial operator is anonymised as Nova Fluid Systems, an overseas engineering enterprise supplying hydraulic valve assemblies for North‑American industrial clients. To insulate itself from U.S. patent litigation risks, Nova Fluid Systems organised product sales into a two‑layer corporate structure. It created a Texas‑registered import‑focused limited‑liability company named Valve Imports LLC, whose members and managing member were third‑party professional nominee agents. Nova Fluid Systems’ corporate name never appeared on customs entry documents, Amazon Business store profiles, commercial invoices or U.S.‑side bank merchant accounts. The nominal shell Valve Imports LLC only held import licences, marketplace seller qualifications and receiving bank accounts. Nominee managers collected fixed annual retainer fees and possessed zero authority over product specification, overseas manufacturing order placement, pricing strategy or profit distribution. This organisational arrangement was deliberately built so that if patent litigation arose, plaintiffs would only sue the low‑asset U.S. domestic shell entity, making substantial damage awards difficult to collect under 35 U.S.C. § 271 patent infringement statute.
The plaintiff holds a valid U.S. utility patent covering a high‑pressure hydraulic flow‑control valve assembly, with asserted independent claims directed at internal channel structure and sealing‑component cooperation mechanisms. The patent had survived inter‑partes review proceedings at the USPTO and remained enforceable. After discovering multiple batches of infringing hydraulic valves circulating within the U.S. industrial supply chain, the patent holder traced the visible importer of record to Valve Imports LLC. The shell‑operated Amazon Business store sold large quantities of accused valves to maintenance contractors, manufacturing plants and equipment resellers across multiple U.S. states. All physical manufacturing, component assembly and quality testing were completed at overseas production facilities fully controlled by hidden Nova Fluid Systems. Valve Imports LLC performed only customs clearance, domestic warehousing and order fulfilment tasks following precise product‑shipment instructions transmitted from overseas. It conducted no product design, technical modification or independent supplier negotiation.
The patentee filed an initial complaint naming only Valve Imports LLC as defendant. During early‑stage litigation, counsel for Valve Imports raised two core defence arguments. First, the LLC functioned merely as an independent import broker performing logistics and customs work; it had no participation in product design or overseas manufacturing and could not be held liable for induced patent infringement. Second, no public written contract existed on U.S. state‑filing records connecting Nova Fluid Systems to Valve Imports LLC, so the overseas beneficial entity should not be added as a party to this domestic patent action. Should the court accept these contentions, the patent owner would obtain a formal judgment against a shell company with minimal tangible assets. Almost all sales proceeds from infringing hardware flowed back to overseas bank accounts controlled by Nova Fluid Systems, leaving little‑to‑no domestic assets available for execution of monetary damages.
The plaintiff invoked federal civil discovery mechanisms and issued subpoenas directed at U.S. Customs and Border Protection, e‑commerce marketplace operators, domestic third‑party warehouse providers and payment‑processing institutions. Multiple decisive factual links were established. First, customs entry filings and shipping instructions demonstrated that product technical specifications, part‑number configurations and manufacturing change‑orders originated directly from Nova Fluid Systems engineering teams. Valve Imports never altered product technical parameters. Second, comprehensive payment records showed that after customer purchase funds landed in Valve Imports’ U.S. bank account, more than ninety‑two percent of gross revenue was remitted overseas to Nova Fluid‑controlled accounts within five business days; the domestic shell retained only pre‑agreed logistics and nominee‑administration service fees. Third, stored internal business correspondence proved that Nova Fluid Systems unilaterally determined U.S. retail price ranges, inventory replenishment volumes and promotional schedules for the American marketplace. Fourth, sworn deposition statements from the nominee managing‑member confirmed that he solely provided identity credentials for state‑level LLC formation and never engaged in substantive business decision‑making.
Applying Texas state alter‑ego standards together with federal patent‑tort jurisprudence, the district court ruled that Valve Imports LLC operated purely as a domestic import instrumentality for Nova Fluid Systems, lacking separate genuine business objectives. Complete unity of control and profit diversion existed between the two entities, and the shell was created principally to evade potential U.S. patent‑infringement liabilities. The hidden overseas principal directed key infringing activities and captured the overwhelming share of economic gains from the accused hardware sales. Accordingly, Nova Fluid Systems and Valve Imports constituted joint tortfeasors subject to joint‑and‑several liability for patent‑infringement compensatory damages. The court overruled the motion to dismiss directed against Nova Fluid Systems.
In the final judgment, both defendants were ordered to cease importation, offer‑for‑sale and sale of infringing hydraulic valve products inside United States territory. The court awarded compensatory damages plus recoverable reasonable attorney fees under 35 U.S.C § 284 and § 285. This case delivers meaningful practical lessons for patent owners enforcing rights in U.S. import‑related disputes. Relying exclusively upon customs‑listed importer‑of‑record information to frame defendants carries severe enforcement risk. Rights holders must utilise discovery subpoenas targeting customs records, payment processors and warehouse operators to trace concealed beneficial principals. Judgments limited solely against domestic nominee import shells frequently result in uncollectible awards. Successful patent enforcement against overseas‑sourced infringing goods hinges on identifying the entity controlling product specifications and receiving primary infringement‑derived profits.
