This authentic patent civil dispute was adjudicated by United States District Court for the District of Delaware (Case No.1:23‑cv‑01047). It reflects a common cross‑border infringement tactic in mechanical equipment trade: offshore manufacturers establish thinly‑capitalized U.S. domestic shell companies operated by nominee agents, solely responsible for local e‑commerce store operation, order reception and invoicing. The real manufacturing entity stays overseas, completely hidden behind domestic nominal distributors. Once facing patent litigation, the shell entity claims independent corporate personality, while the offshore manufacturer attempts to cut off jurisdictional connection and evade U.S. patent damage awards under 35 U.S.C. §271.
The plaintiff, anonymized as Nova Handling Technologies Inc., is the patent holder of U.S. Utility Patent US11,479,627, covering an improved automated sorting apparatus for warehouse logistics. The patent obtained grant in 2022 and had been commercially implemented across North America. In late 2023, the plaintiff’s market investigation team discovered large‑volume infringing sorting machines sold on mainstream U.S. B2B e‑commerce platforms. All online store registration information, sales contracts and commercial invoices were issued under the name of Boreal Industrial Supply LLC, a Delaware‑registered domestic shell company. Its listed manager was a nominee receiving fixed annual agency compensation, without participating in product design, production planning or profit distribution. Boreal Industrial Supply possessed no factory workshop, processing equipment or in‑house engineering personnel.
At the preliminary investigation stage, the patent holder initially prepared to sue only Boreal Industrial Supply LLC. Asset check revealed that this nominal defendant maintained merely approximately 11 000 US‑dollars of total book assets, far lower than potential multi‑million‑dollar patent compensation. If litigation was limited only to this domestic shell, even obtaining a favorable judgment would face severe obstacles in property enforcement, since all core manufacturing capacity and infringement profit belonged to an undisclosed offshore industrial group. The plaintiff recognized that nominal sales entity information shown on e‑commerce platforms cannot be equated with actual infringing manufacturer, which constitutes a major pitfall in U.S. cross‑border patent enforcement.
The plaintiff filed comprehensive motions for federal civil jurisdictional and merits‑based discovery. The court granted subpoenas directed at e‑commerce platform backend data, cross‑border logistics manifests, third‑party payment transaction records, domain registration documents and corporate internal communication archives. Through forensic document review, multiple critical facts emerged. First, although Boreal Industrial Supply signed sales contracts with American buyers and issued invoices, almost all customer payments were eventually remitted to overseas bank accounts controlled by Atlas Machinery Group, the hidden real manufacturer. The domestic shell only retained small fixed commission fees for each finished transaction. Second, all infringing sorting equipment was directly shipped from Atlas Machinery’s overseas manufacturing plant to United States purchasing customers; goods never entered any warehouse managed by Boreal Industrial Supply. Third, internal email records demonstrated that product technical parameters, unit pricing, after‑sales repair schemes and delivery schedules were 100 % formulated and adjusted by Atlas Machinery’s engineering department. The U.S. shell company had no authority to modify product structures or resolve technical complaints from end‑users.
The offshore defendant Atlas Machinery argued that it had no direct business presence inside United States territory, and all sales activities were independently undertaken by separate U.S. domestic legal entity Boreal Industrial Supply. Therefore, Atlas should not be subject to personal jurisdiction of Delaware federal court and should not bear patent‑infringement liability. After evaluating massive discovery evidence, the district court applied federal alter‑ego two‑factor test for corporate‑veil piercing. The court confirmed unity of ownership and full operational domination: Boreal Industrial Supply had no independent business judgment and existed merely as U.S. market sales instrument for Atlas Machinery. Moreover, the evidence proved that establishing this domestic shell was for the improper purpose of evading United States patent‑infringement legal risks. Accordingly, the court ruled that Atlas Machinery and Boreal Industrial Supply constituted joint tortfeasors under U.S. patent law, satisfying personal jurisdiction requirements.
Considering willful copying of patented technical solution, deliberate adoption of shell‑company structure to obstruct patent right enforcement, and relatively large annual infringing sales volume as aggravating factors, the court issued permanent injunction prohibiting manufacture, importation, offer‑for‑sale and sale of accused sorting devices. Atlas Machinery and Boreal Industrial Supply bore joint and several liability for enhanced patent‑infringement damages pursuant to 35 U.S.C. §284. The judgment also ordered destruction of all detained infringing finished goods and special production moulds. Pure nominee individual manager who only lent identity for registration without participating any business activity obtained exemption from personal liability.
This case delivers vital practical guidance for global enterprises enforcing U.S. patent rights. First, plaintiffs cannot simply rely on e‑commerce displayed seller entities to define litigation defendants. Second, claimants should actively utilize federal discovery mechanism to obtain logistics documents, cross‑border capital flow evidence and internal corporate communications to build alter‑ego proof chain. Third, patent owners need to pay close attention to personal‑jurisdiction requirements when pursuing hidden offshore manufacturers. For non‑U.S. patent holders, early market monitoring and full use of judicial subpoena tools help break shell‑company concealment tactics and achieve real relief effect for U.S. patent assets.
