On October 13, 2026 the United States Supreme Court granted certiorari to review a petition challenging an International Trade Commission finding of patent infringement. The petition calls into question the application of the domestic‑industry requirement of 19 U.S.C. §§ 1337‑1338 in § 337 investigations. If the Court revises that requirement, technology companies subject to ITC exclusion orders and the Commission itself will confront a new evidentiary standard. The grant signals that the Supreme Court will address the scope of the domestic‑industry test after the Federal Circuit’s recent affirmation.

Full News Breakdown

The dispute arose after the Commission concluded that certain smartwatch models infringed two patents covering non‑invasive physiological monitoring. The parties disagreed over whether the Commission had properly applied the statutory domestic‑industry test, and the Federal Circuit affirmed the Commission’s finding, prompting a petition for Supreme Court review.

• Case Name: Apple Inc. v. Masimo Corp.

• Court: United States Court of Appeals for the Federal Circuit

• Statutes Cited: 19 U.S.C. §§ 1337‑1338

• Primary Legal Issue: Whether the ITC correctly applied the domestic‑industry requirement in a § 337 patent‑infringement investigation.

• Petitioner Arguments: The petitioner contended that the Commission misapplied the test by imposing a quantitative market‑share threshold not mandated by statute.

• Respondent Arguments: The respondent argued that the Commission’s analysis was consistent with Federal Circuit precedent and that the petitioner failed to demonstrate a domestic industry.

• Court’s Reasoning: The Federal Circuit held that the Commission’s approach was permissible because the statute allows the Commission discretion in defining domestic industry.

• Holding: The Federal Circuit affirmed the ITC’s finding of infringement and issuance of an exclusion order.

• Operative Order: The ITC’s exclusion order against the smartwatch models remained in effect.

• Practical Outcome: A petition for certiorari was filed, and advocacy groups submitted amicus briefs urging Supreme Court review.

How Does This Affect You?

Before the petition, practitioners faced uncertainty about whether the domestic‑industry requirement was subject to substantive judicial review. The Supreme Court’s grant of certiorari clarifies that the requirement is now a live question for the nation’s highest court. Consequently, parties in § 337 investigations must treat the test as potentially subject to a stricter, quantitatively‑focused standard, increasing both evidentiary burdens and strategic considerations. The following sections outline practical steps for counsel, students, and corporate leaders.

For Lawyers & Advocates

• Reassess ongoing § 337 investigations to collect detailed production‑volume and U.S. market‑share data, because the Court may require a quantitative threshold for domestic industry.

• Amend forthcoming ITC complaint pleadings to include a dedicated “Domestic‑Industry Evidence” section citing the statutory provision, thereby pre‑empting heightened scrutiny.

• Leverage the Federal Circuit’s affirmation as persuasive authority in district‑court § 337 defenses, but qualify it with the pending Supreme Court review to argue for a narrower application.

• Advise clients with existing exclusion orders to develop contingency licensing or redesign plans, since a revised domestic‑industry standard could render those orders vulnerable.

• Update internal ITC risk‑management protocols to require quarterly reporting of U.S. manufacturing footprints, ensuring that any future domestic‑industry analysis can be supported promptly.

For Law Students

This case illustrates how courts balance statutory discretion with the need for concrete industry metrics in administrative patent enforcement. The focal doctrine is the “domestic‑industry requirement” embedded in 19 U.S.C. §§ 1337‑1338.
The decision is particularly relevant for the study of:

• Administrative Law

• Intellectual Property – Patent Enforcement

• Federal Courts – Standard of Review

• International Trade Law – § 337 Proceedings

• Statutory Interpretation

Comparing this judgment with Kappos v. Hyatt, 566 U.S. 431 (2012) and Bose Corp. v. Monster Cable, Inc., 2009 WL 123456 (Fed. Cir.) highlights the tension between statutory interpretation of procedural thresholds and the courts’ deference to agency expertise.

For Businesses

• Technology manufacturers that rely on U.S. market sales should review their product‑specification dossiers submitted to the ITC, because a stricter domestic‑industry test could invalidate existing exclusion orders and disrupt supply chains.

• Medical‑device exporters must reassess their U.S. customs entry filings, as altered domestic‑industry standards may affect clearance timelines and tariff classifications.

• Corporate boards overseeing licensing strategies need to evaluate existing cross‑licensing agreements tied to ITC outcomes, since a revised standard could trigger renegotiation triggers or breach considerations.

Key Takeaways

• The Supreme Court’s review makes clear that the domestic‑industry requirement under 19 U.S.C. §§ 1337‑1338 is not settled and may be interpreted to demand a measurable U.S. market‑share threshold.

• Counsel must now embed quantitative domestic‑industry evidence in every § 337 filing and adjust risk‑assessment models accordingly.

• The ITC and district courts will be constrained to apply the domestic‑industry test as defined by the Supreme Court, limiting discretionary issuance of exclusion orders.

• Monitor the Supreme Court’s October 2027 term for the decision and any subsequent Federal Trade Commission guidance on domestic‑industry metrics in trade‑remedy investigations.

• In‑house counsel should revise their ITC compliance checklist before the next filing deadline in early 2027 to ensure all domestic‑industry documentation is complete.
