Summary

The U.S. International Trade Commission instituted Investigation No. 337-TA-XXXX on April 8, 2026, following a complaint filed by Belkin International, Inc. on March 9, 2026, alleging violations of Section 337 of the Tariff Act based on patent infringement. The complaint targets importation and sale of certain screen protectors for mobile phones, smartwatches, and tablet computers, as well as application systems, allegedly infringing three patents: U.S. Patent Nos. 10,675,817, 10,782,746, and 11,772,320. Belkin requests issuance of a limited exclusion order and cease and desist order.

What changed

The ITC has instituted an investigation to determine whether there is a violation of Section 337 based on importation and sale of screen protectors and application systems infringing claims of three Belkin patents. The investigation covers claims 1-19 of the '817 patent, claims 1-20 of the '746 patent, and claims 1-18 of the '320 patent.

Parties importing or selling accused screen protectors and application systems should be aware that a finding of violation could result in issuance of a limited exclusion order barring entry of infringing products and a cease and desist order prohibiting domestic sales. Respondents named in the investigation should engage ITC counsel to prepare a defense.

What to do next

  1. Monitor ITC Investigation No. 337-TA-XXXX for updates
  2. Consult legal counsel if involved in importing accused screen protector products
  3. Review patent portfolio for potential overlap with asserted patents

Federal Statute. The complainant requests that the Commission institute an investigation and, after the investigation, issue
a limited exclusion order and a cease and desist order.

(1) Pursuant to subsection (b) of section 337 of the Tariff Act of 1930, as amended, an investigation be instituted to determine
whether there is a violation of subsection (a)(1)(B) of section 337 in the importation into the United States, the sale for

of infringement of one or more of claims 1-19 of the '817 patent; claims 1-20 of the '746 patent; and claims 1-18 of the '320

(2) Pursuant to section 210.10(b)(1) of the Commission's Rules of Practice and Procedure, 19 CFR 210.10(b)(1), the plain language
description of the accused products or category of accused products, which defines the scope of the investigation, is “screen
