The Decision NHK Spring is petitioning the U.S. Supreme Court to review a decision by the U.S. Court of Appeals for the Ninth Circuit. The Ninth Circuit decision revived a price-fixing lawsuit brought by Seagate Technology LLC. The underlying dispute in the Seagate Technology Case involves allegations concerning hard drive component pricing. Following the appellate ruling that allowed the claims to proceed, NHK Spring filed its petition to challenge the application of domestic law to foreign commerce. NHK Spring argues that U.S. antitrust law should not apply to overseas sales. ## Why It Matters The petition asks the justices to establish firm boundaries on the geographic reach of American antitrust enforcement. NHK Spring asserts that the only connection to the United States for these specific sales is their partial negotiation within the country. If the Supreme Court agrees to hear the case, it will address whether partial domestic negotiation is a sufficient basis to subject foreign transactions to U.S. courts. A definitive ruling would dictate how multinational corporations structure their sales and negotiation teams. When companies negotiate global supply agreements, executives often meet in various jurisdictions. If partial negotiation in the United States opens the door to domestic price-fixing liability for sales executed entirely overseas, foreign manufacturers face massive exposure under U.S. antitrust laws. Conversely, limiting the law's reach would restrict the ability of U.S.-based buyers to recover losses incurred through global price-fixing arrangements when the final transactions occur abroad. ## Who Should Care ### For lawyers Antitrust practitioners, corporate counsel, and litigators dealing with cross-border disputes must monitor this petition. The case presents a fundamental question about the extraterritorial application of the Sherman Act and related statutes. Lawyers advising multinational clients on compliance will need to track whether the Supreme Court views partial domestic negotiation as sufficient domestic conduct to satisfy the statutory requirements for U.S. jurisdiction. A grant of certiorari would signal the Court's interest in clarifying the boundaries of foreign commerce antitrust litigation, potentially altering the standards for pleading domestic injury. ### For consumers and parties Technology manufacturers, component suppliers, and multinational buyers are directly affected by the rules governing international supply chains. For buyers like Seagate Technology LLC, the ability to sue in U.S. courts for price-fixing on components purchased overseas provides a powerful tool to recover overcharges. For foreign suppliers like NHK Spring, defending against U.S. antitrust lawsuits for overseas sales represents a significant legal and financial burden. The outcome of this petition will influence where and how global companies choose to negotiate their contracts to avoid or secure the protection of American antitrust laws. ## Legal Background U.S. antitrust laws primarily target anti-competitive behavior that harms domestic commerce. However, the global nature of modern manufacturing frequently blurs the lines between domestic and foreign conduct. Courts routinely evaluate claims where products are manufactured in one country, negotiated in a second, and sold in a third. To manage these cross-border disputes, federal law establishes limits on when U.S. antitrust statutes apply to foreign conduct. Generally, the conduct must have a direct, substantial, and reasonably foreseeable effect on U.S. commerce, and that effect must give rise to the plaintiff's injury. Disputes frequently arise over what specific actions constitute domestic conduct versus foreign conduct. Defendants in international price-fixing cartels often argue that if the actual sale and delivery of the goods occurred overseas, U.S. courts lack jurisdiction, regardless of where corporate executives met or where the buyer is headquartered. Plaintiffs counter that negotiations and pricing agreements reached on U.S. soil infect the entire global supply chain, thereby bringing the foreign sales within the scope of domestic law. ## What the Court Did The Ninth Circuit previously issued a decision that revived the price-fixing lawsuit brought by Seagate Technology LLC. By reinstating the claims in the Seagate Technology Case, the appellate court determined that the allegations concerning hard drive component pricing were sufficient to survive early dismissal, even regarding the overseas transactions. In response to that revival, NHK Spring filed its petition for a writ of certiorari with the U.S. Supreme Court. The petition focuses narrowly on the geographic location of the sales and the negotiations. NHK Spring argues that the Ninth Circuit erred in its jurisdictional analysis because the actual sales of the hard drive components took place overseas. Furthermore, NHK Spring asserts that the only connection to the United States for these overseas sales is the fact that they were partially negotiated within the country. The company contends that partial negotiation is an inadequate basis for applying U.S. antitrust law to foreign commerce. ## How It May Be Applied If the Supreme Court grants the petition and ultimately reverses the Ninth Circuit, foreign suppliers will gain a stronger shield against U.S. antitrust litigation. Companies could structure their operations so that final sales and deliveries occur abroad, knowing that partial negotiations in the United States will not automatically subject those specific transactions to domestic price-fixing claims. This would require U.S. buyers to seek remedies in foreign jurisdictions for overseas purchases, even if the purchasing agreements were hammered out in American boardrooms. Alternatively, if the Supreme Court denies the petition, the Ninth Circuit's decision will stand, leaving the door open for plaintiffs to pursue U.S. antitrust claims based on partial domestic negotiations. This outcome would force multinational corporations to carefully separate their negotiation teams. Suppliers might prohibit executives from discussing pricing or contract terms while physically present in the United States to avoid creating the domestic nexus required for antitrust liability. The lingering uncertainty would likely lead to increased litigation over exactly how much domestic negotiation is required to trigger U.S. jurisdiction. ## Jurisdictional Approaches to Foreign Sales
| Scenario | NHK Spring's Position | Ninth Circuit's Approach |
|---|---|---|
| Sales executed overseas with partial U.S. negotiation | U.S. antitrust law should not apply due to the foreign nature of the sale. | The domestic negotiation provides a sufficient connection to revive price-fixing claims. |
| Sales executed entirely domestically | Fully subject to U.S. antitrust law. | Fully subject to U.S. antitrust law. |
| Sales executed overseas with zero U.S. connection | U.S. antitrust law does not apply. | U.S. antitrust law does not apply. |
The Ninth Circuit issued the decision NHK Spring asks the Supreme Court to review on January 8, 2026; NHK filed its certiorari petition in June 2026.
