This case originates from a 2024 final judgment of the U.S. District Court for the Northern District of Texas, a landmark ruling addressing defendant-side use of shell companies to conceal patent infringement liability. The plaintiff, a domestic precision motion control component manufacturer, holds a utility patent covering an integrated linear drive assembly used in industrial automation equipment. The named defendants in the initial lawsuit were two low-asset distribution companies: Boreal Industrial Supply LLC and Summit Parts Distribution LLC. Through pre-trial discovery, the plaintiff uncovered that both nominal defendant companies were shell entities entirely controlled by Atlas Machinery Group (an alias for the actual overseas manufacturing parent company, anonymized per court protective order). Atlas designed, manufactured, and supplied all of the infringing linear drive assemblies sold by the two shell companies, while deliberately structuring the U.S. sales channel through undercapitalized shell entities to insulate its core manufacturing assets from intellectual property liability. Five binding legal standards govern the court’s veil-piercing analysis and infringement ruling:
● 35 U.S.C. § 271(a) statutory definition of direct patent infringement: Any entity that makes, uses, offers to sell, sells, or imports a patented invention within the U.S. without authorization commits direct infringement, regardless of whether it operates through nominal third-party corporate entities.
● Two-prong federal alter ego veil-piercing standard: To disregard separate corporate personality, a plaintiff must prove (1) complete unity of ownership and operational control such that the shell entity has no independent legal identity, and (2) the corporate form was used to perpetrate a fraud, wrong, or violation of law that causes foreseeable harm to the plaintiff.
● 35 U.S.C. § 284 enhanced damages for willful patent infringement: Courts may award up to three times the compensatory damages if the infringer acted with deliberate disregard of patent rights, including deliberate use of shell entities to evade liability.
● 35 U.S.C. § 285 attorney fee shifting for exceptional cases: In exceptional cases involving egregious litigation conduct or intentional infringement concealment, prevailing plaintiffs may recover reasonable attorney fees and costs from the infringing parties.
● Fraudulent use of corporate form to evade legal obligations: This is the core equitable justification for veil piercing, applicable when a defendant creates shell entities specifically to avoid paying court-ordered damages or complying with injunctive relief.
After granting the plaintiff’s motion for broad discovery into corporate ownership and financial records, the court established the following conclusive facts demonstrating Atlas’s total control over the two defendant shell companies: First, there was complete identity of decision-making and personnel. The two shell companies had no full-time employees, no independent engineering or quality control teams, and no standalone sales operations. All customer negotiations, pricing decisions, and product specification changes were directly determined by Atlas’s sales and engineering management teams. The registered owners of the two LLCs were low-level administrative staff employed by Atlas’s U.S. liaison office, with no independent authority to make business decisions or retain litigation counsel. Second, there was systematic commingling of assets and one-way profit transfer. All inventory sold by the shell companies was consigned directly from Atlas’s overseas manufacturing facilities, with no upfront purchase payment and no inventory risk borne by the shell entities. Every dollar of customer revenue was wired to Atlas’s offshore parent account within 10 business days of receipt, minus a tiny fixed monthly administrative stipend used only to pay state franchise taxes and registered agent fees. Neither shell company maintained independent financial statements, separate bank reserves, or liability insurance sufficient to cover potential patent damage awards. Third, the shell entities were deliberately undercapitalized to avoid enforcement. At the time of the lawsuit, Boreal Industrial Supply had less than $12,000 in total assets, and Summit Parts Distribution had less than $8,000, far below the estimated multi-million dollar infringement damages. Internal Atlas emails produced in discovery explicitly referenced using “separate U.S. distribution shells” to “limit IP exposure” and “shield manufacturing assets from patent lawsuits”, directly proving the unlawful purpose behind the corporate structure. When first served with the complaint, both shell companies filed motions to dismiss arguing they were mere passive distributors with no knowledge of the patent, and that their separate corporate status limited any potential judgment to their minimal on-book assets.
The court issued a final judgment in favor of the patent owner, applying the two-prong alter ego test to formally pierce the corporate veil and hold Atlas Machinery Group jointly and severally liable for all infringement damages. On the first prong of the test, the judge found complete unity of ownership and operational control between Atlas and the two shell distribution companies. The shell entities had no genuine independent business purpose, no autonomous decision-making authority, and no separate economic identity apart from serving as Atlas’s U.S. sales front. All core functions that define a legitimate distribution business — product sourcing, pricing, customer support, warranty fulfillment — were performed exclusively by Atlas personnel. On the second prong, the court concluded that Atlas had used the shell corporate structure for the unlawful purpose of evading patent infringement liability. The internal strategy emails proved that Atlas established the shell entities with the explicit intent to create a legal barrier between its profitable manufacturing operations and U.S. intellectual property claims, making it nearly impossible for patent holders to collect on infringement judgments. This deliberate structuring to avoid legal obligations constituted a wrongful abuse of the corporate form, satisfying the second requirement for veil piercing. On damages, the court found the infringement to be willful, given Atlas’s deliberate copying of the patented design and its intentional use of shell companies to conceal its conduct. Pursuant to 35 U.S.C. § 284 enhanced damages for willful patent infringement, the court awarded 2.5 times the base compensatory damages, totaling $7.8 million. The court further ruled the case exceptional under **35 U.S.C. § 285 attorney fee shifting for exceptional cases**, ordering Atlas and the shell companies to pay $1.2 million in reasonable attorney fees and forensic discovery costs to the plaintiff. Finally, the court issued a permanent nationwide injunction prohibiting Atlas, its shell entities, and any affiliated companies from making, selling, or importing the infringing linear drive assemblies into the United States.
This ruling clarifies two critical takeaways for companies selling patented products into the U.S. market. First, creating undercapitalized U.S. distribution shell companies will not shield foreign or domestic parent manufacturers from patent infringement liability. Federal courts routinely look beyond nominal corporate structure to examine actual operational control, profit allocation, and the purpose for which the shell entities were created. When a parent company exercises total control over product design, pricing, and inventory, and collects nearly all sales revenue, courts will almost always treat the shell and parent as a single liable entity. Second, deliberate use of shell structures to conceal infringement and avoid damage awards will be treated as an aggravating factor, triggering enhanced damages and fee shifting. Internal documents referencing risk mitigation through separate corporate entities can be used as direct evidence of willful infringement and fraudulent purpose, significantly increasing financial exposure. For companies operating through multi-tier distribution channels, the safest compliance approach is to conduct full freedom-to-operate patent clearance reviews before launching products in the U.S., rather than relying on corporate structuring to avoid liability.
