On April 8, 2026, the U.S. International Trade Commission instituted Investigation No. 337-TA-1497 targeting certain screen protectors, application systems, and components thereof. The investigation stems from a complaint filed by Belkin International, Inc. on March 9, 2026, alleging patent infringement related to imports of mobile device accessories—a product category that moves through U.S. Customs in substantial volumes daily.
The investigation centers on three patents: U.S. Patent No. 10,675,817, U.S. Patent No. 10,782,746, and U.S. Patent No. 11,772,320. Belkin alleges that Superior Communications, Inc. of Irwindale, California has violated Section 337 of the Tariff Act of 1930 through the importation, sale for importation, and sale within the United States after importation of infringing products. The complaint covers claims 1-19 of the '817 patent, claims 1-20 of the '746 patent, and claims 1-18 of the '320 patent.
The scope of accused products is explicitly defined: screen protectors for mobile phones, smartwatches, and tablet computers, plus the application systems used with them. This includes trays that hold devices during screen protector application, as well as the films, tabs, and screen protectors used in the application process. Trade compliance systems handling HTS classifications for mobile device accessories—typically falling under headings like 3926 (plastic articles) or 7007 (safety glass)—should flag this investigation for monitoring.
Why This Matters for Compliance Engineering: If the ITC issues the requested limited exclusion order and cease and desist order, specific screen protector products from the named respondent would be barred from U.S. entry. Customs enforcement would require accurate product identification at the HTS code level to implement any exclusion.
Belkin has requested both a limited exclusion order and a cease and desist order. A limited exclusion order would direct U.S. Customs and Border Protection to stop infringing products from the specifically named respondent at the border. Unlike a general exclusion order, it applies only to products from parties found to violate Section 337—but it still creates classification verification requirements for importers of similar goods who must demonstrate their products are not covered.
For compliance engineering teams, the procedural timeline matters. Section 337 investigations typically conclude within 12-18 months. The Commission has designated an Administrative Law Judge to preside, and notably, the Office of Unfair Import Investigations will not participate as a party. This means the investigation proceeds as a two-party dispute between Belkin and Superior Communications, potentially moving faster than investigations with OUII involvement.
Action Required: Systems that cache HTS duty rates or automate entry classification for mobile accessories should implement monitoring for ITC exclusion order issuances. If an exclusion order issues in Investigation 337-TA-1497, affected HTS codes may require additional admissibility flags beyond standard duty rate data.
The Federal Register notice, published April 13, 2026, provides access to non-confidential complaint materials through the Commission's EDIS system. Compliance teams can track case developments through the ITC's electronic docket to anticipate enforcement requirements before any exclusion order takes effect at the border.
