This patent infringement civil case was adjudicated by United States District Court for the Northern District of Texas in 2024. The dispute centered on utility patent infringement for industrial linear drive assemblies used in automated production equipment. The actual offshore original‑equipment manufacturer, responsible for product design, core component production and finished‑goods assembly, is anonymised as Atlas Machinery Group. Atlas never appeared on U.S. import customs filings, e‑commerce seller registrations, product invoices or distributor contracts. Two under‑capitalized domestic limited‑liability companies were created exclusively for U.S.‑market import and sales: Boreal Industrial Supply LLC and Summit Parts Distribution LLC. Nominal agents acted as managers for both shell entities; they received fixed monthly administrative fees but held zero authority over technical design, production scheduling, pricing strategy or profit distribution.
Starting in early 2022, Atlas Machinery Group replicated every technical limitation covered by the plaintiff’s valid U.S. utility patent, without obtaining patent licensing or performing freedom‑to‑operate risk assessment. All infringing linear‑drive products were fully manufactured at Atlas’s overseas production base. Boreal Industrial Supply and Summit Parts Distribution performed only import clearance, domestic warehousing and customer sales. All customs entry documents, Amazon‑style marketplace seller accounts, commercial invoices and distributor agreements bore only the names of the two shell companies. No public‑facing business document mentioned Atlas Machinery Group. This corporate framework was intentionally built to separate high‑value offshore manufacturing assets from U.S. patent‑infringement judgment risk. If litigation arose, the plan was to let the low‑asset U.S. shell entities bear all legal exposure, while Atlas’s core production facilities remained protected from monetary awards.
The patent owner first detected infringing products sold across multiple U.S. industrial‑equipment sales channels. Cease‑and‑desist letters were sent to Boreal and Summit. Both shell‑company representatives replied that they were merely passive importing resellers and possessed no knowledge of underlying patent issues. The plaintiff filed its initial federal complaint naming only Boreal Industrial Supply LLC and Summit Parts Distribution LLC as defendants. At the early litigation phase, the patent holder faced severe enforcement risks. Each shell maintained minimal book assets: Boreal held roughly $12,000 total assets, and Summit held less than $8,000. If judgment ran solely against these nominal defendants, the real manufacturing infringer Atlas Machinery Group could escape paying substantial damages by abandoning the insolvent U.S. shell companies. The plaintiff’s litigation team learned a key practical lesson under U.S. patent procedure: the import‑record importer‑of‑record or marketplace‑seller entity does not automatically equal the entity that makes and designs the patented product.
During extensive federal‑court‑ordered discovery, multiple categories of critical evidence were collected via document subpoenas, forensic hardware inspection and production‑site deposition testimony. First, hardware forensic analysis of seized infringing units uncovered internal firmware build metadata, component serial‑number encoding rules and manufacturing batch markers that traced directly back to Atlas’s overseas production management system. Neither shell company employed hardware engineers or owned any manufacturing equipment. Second, forensic financial reconstruction revealed consistent capital‑flow patterns: revenue generated from U.S. product sales received by each shell entity was transferred offshore to Atlas’s central bank account within ten business days. The two domestic shells only retained tiny fixed administrative fees to cover registered‑agent costs and state franchise taxes. Complete commingling of revenue, absence of genuine arm’s‑length inter‑company contracts and failure to maintain independent corporate records strongly supported the argument that Boreal and Summit functioned purely as alter‑ego instrumentalities of Atlas Machinery Group. Third, internal Atlas business emails obtained during discovery contained explicit instructions from senior management: “Use separate U.S. import shells to limit IP exposure and shield our manufacturing assets from U.S. patent lawsuits.” This documentary evidence proved that setting‑up the two U.S.‑based shell companies was a deliberate risk‑evasion strategy, rather than ordinary commercial business planning.
In court arguments, counsel for Boreal and Summit contended that they were independent import resellers, and corporate‑separation principles should insulate Atlas from liability. Atlas’s legal representatives initially denied any direct operational control over the two U.S. limited‑liability companies. After evaluating forensic hardware evidence, bank‑transaction records, internal corporate emails and witness testimony, the district court made its key factual findings. First, Boreal Industrial Supply LLC and Summit Parts Distribution LLC had no independent legitimate business purpose apart from importing and selling Atlas‑manufactured infringing goods; they lacked independent decision‑making power, separate operating staff and autonomous economic existence. Second, Atlas Machinery Group exercised full control over product design, manufacturing output, pricing policy and profit distribution. Third, the multi‑entity corporate structure was intentionally constructed to conceal the real manufacturing infringer and frustrate patent‑right enforcement, satisfying the federal‑common‑law two‑prong alter‑ego test for corporate‑veil piercing.
Under 35 U.S.C. § 271(a) and § 284, the court disregarded the separate corporate identities of the two shell LLCs. Atlas Machinery Group, together with Boreal Industrial Supply LLC and Summit Parts Distribution LLC, were held jointly and severally liable for willful direct patent infringement. Total compensatory and enhanced damages awarded to the patent plaintiff reached $2.17 million USD. A permanent injunction prohibited all defendants from making, importing, offering for sale or selling products practicing the asserted utility patent claims.
This case delivers essential practical guidance for patent owners pursuing cross‑border patent infringement within the United States. Relying merely on customs import records or marketplace‑seller registration information to identify defendants creates major enforcement vulnerability. Right holders must leverage federal discovery tools to obtain hardware forensic evidence, full bank‑transaction trails and internal corporate communications. When overseas manufacturers deploy multiple disconnected U.S. import‑oriented shell entities, litigators should trace the complete control and profit chain instead of only suing surface‑level domestic importers.
