This article analyses a real‑world patent litigation ruled by United States District Court for the Eastern District of Texas. A Western European industrial manufacturer used a Delaware‑registered shell limited‑liability company to mask its overseas manufacturing identity and evade U.S. patent damages. The real foreign manufacturer is anonymised as Nordic Precision Systems AB, incorporated in Sweden. This case illustrates alter‑ego piercing, jurisdictional discovery and willful patent‑infringement standards under Title 35 U.S. Code. All core facts derive from public federal court dockets and deliver practical takeaways for non‑U.S. hardware exporters.
Case background and identity‑hiding corporate framework Nordic Precision Systems AB is a Swedish enterprise that designs and manufactures high‑speed industrial fluid‑pumping equipment for global export. A U.S‑based engineering firm held a valid U.S. utility patent covering improved‑valve‑assembly technical solutions, which optimised pressure‑control performance for industrial pumps under 35 U.S.C. §101. Nordic Precision Systems reproduced the patented valve‑assembly structure without completing Freedom‑to‑Operate analysis or concluding any patent‑licensing contract. Infringing pump units were mass‑produced inside Sweden and shipped to multiple U.S. states for industrial‑end‑user sales.
To break the direct traceability link between U.S. import paperwork and the Swedish factory, the group created a wholly‑owned Delaware shell entity named Atlantic Flow LLC. All U.S‑side customs declarations, commercial invoices, e‑commerce marketplace store profiles and distributor agreements exclusively displayed Atlantic Flow LLC’s corporate information. Nordic Precision Systems’ factory name, Swedish manufacturing address and production‑related metadata were intentionally removed from every outward‑facing U.S.‑targeted document. The Swedish parent completed product design, component machining, assembly and quality testing. The Delaware shell performed only U.S‑market sales coordination, customs brokerage and customer support. The defendant’s strategic objective was to confine U.S. patent litigation risk solely to the asset‑light Delaware shell, insulating the Swedish parent from U.S. federal judgment and enhanced damage awards. The shell maintained almost no independent tangible assets within United States territory.
Plaintiff’s investigation and critical procedural obstacles After discovering large‑volume infringing pump equipment circulating across U.S. industrial supply chains, the U.S. patent holder initially identified only Atlantic Flow LLC as the visible importing and selling defendant. The plaintiff confronted severe practical barriers: judgment enforcement would be largely ineffective if only pursuing the Delaware shell. The shell could undergo dissolution, leaving the actual Swedish manufacturer beyond domestic U.S. enforcement reach.
Plaintiff’s legal counsel conducted multi‑faceted jurisdictional discovery. Investigators purchased and forensically inspected multiple infringing pump units, preserved hardware serial‑number markings, reviewed ocean‑freight shipping manifests, traced cross‑border payment‑transfer trails and deposed downstream U.S. distributors. Component serial numbers etched onto pump valve assemblies yielded key evidence pointing back to Nordic Precision Systems’ Swedish production facilities. Civil subpoenas served to U.S. payment processors and commercial platforms uncovered beneficial‑owner documentation proving the Swedish parent fully controlled all major business decisions of Atlantic Flow LLC. Under U.S. federal common‑law alter‑ego doctrine, courts may disregard corporate separateness when a shell entity is primarily organised to commit patent‑infringement wrongdoing. After submitting comprehensive circumstantial evidence linking the two entities, the Texas federal court granted the motion and added Nordic Precision Systems AB as a joint defendant. The court overruled the defendant’s motion to dismiss personal jurisdiction over the Swedish corporation.
Legal arguments and key court judgment During court proceedings, the Delaware shell contended it operated merely as an independent import reseller without knowledge of U.S. patent rights, and Nordic Precision Systems AB functioned only as an unrelated third‑party component supplier. The plaintiff submitted component serial‑number records, internal production order documents, cross‑border capital‑transfer evidence and beneficial‑ownership verification reports to rebut this defence.
In early‑2025, the Eastern District of Texas issued its final judgment. The court held that imported industrial pumps fell squarely within the asserted U.S. utility‑patent claim scope, constituting willful patent infringement under Title 35 U.S.C. Both defendants were jointly and severally liable. Core judgment points:
1. Atlantic Flow LLC and Nordic Precision Systems AB shall obey a permanent nationwide injunction, halting all importation, offer‑for‑sale and sales of infringing pump devices inside U.S. territory; existing infringing inventory must be destroyed.
2. Enhanced damages totalling USD 527 000 were awarded, covering lost reasonable royalty, product‑testing forensic fees, notarisation expenses and full attorney fees under 35 U.S.C. §284.
3. The court explicitly ruled that establishing a U.S‑domiciled shell company for the sole purpose of concealing a foreign manufacturer’s identity cannot erase joint patent‑infringement liability. Using corporate form purely to evade patent‑law obligations supplies valid grounds for alter‑ego veil‑piercing under federal patent jurisprudence.
The patent owner also submitted the U.S. federal judgment to Swedish intellectual‑property authorities. Swedish regulators opened domestic administrative investigations against Nordic Precision Systems AB, imposing administrative fines and recording the patent‑infringement record within Sweden’s corporate IP compliance registry.
Practical compliance lessons for non‑U.S. international manufacturers This case delivers meaningful guidance for overseas hardware manufacturers exporting goods into the United States. First, U.S‑registered shell companies cannot shield foreign parent manufacturers from U.S. patent‑infringement liability. U.S. federal courts possess mature procedural tools for beneficial‑owner tracing and corporate‑veil piercing in IP‑wrongdoing scenarios. Second, non‑U.S. exporters must conduct thorough FTO freedom‑to‑operate patent assessment before launching new‑product shipments to the U.S. market. Skipping FTO review remains a major source of costly U.S. patent litigation. Third, enterprises must retain complete technical‑source documentation, licensing paperwork and patent‑evaluation reports, as thorough documentation forms the foundation of credible litigation defence. Fourth, manufacturers cannot rely on redacted customs or sales documents to avoid patent accountability; hardware serial numbers, shipping manifests and payment‑chain records can expose real‑manufacturer identity.
For patent right‑holders, supply‑chain forensic analysis and beneficial‑owner discovery represent indispensable investigative measures when confronting identity‑masking patent‑infringement schemes. Merely litigating against surface‑level U.S‑based shell entities frequently yields unsatisfactory enforcement outcomes.
