Certain Wireless Communication Devices and Components Thereof; Notice of Institution of Investigation

📌 ETDETA brief — importer impact summary (educational)

Brief takeaway: The ITC has opened a Section 337 investigation into whether certain wireless communication devices and components infringe six U.S. patents, which could eventually lead to import exclusion and cease-and-desist orders.

What changed: According to the notice, the ITC instituted an investigation on a complaint filed by Active Wireless Technologies LLC alleging that the importation, sale for importation, and post-importation sale of certain wireless communication devices and components violate Section 337 by infringing six patents (the '443, '566, '764, '955, '432, and '557 patents). The notice states the complainant requests a limited exclusion order and cease-and-desist orders after the investigation.

Who's affected: The notice names "certain wireless communication devices and components thereof." It does not specify HTS chapters, codes, or countries of origin. The notice cites the six patents listed above as the basis for the alleged infringement.

What to review:
- Review whether your imported wireless communication devices or components could fall within the scope of products described in this investigation.
- Confirm with your broker or trade counsel whether any of the six cited patents may be relevant to your products or suppliers.
- Check the ITC docket for the investigation number, scope, respondents named, and procedural deadlines as they are published.
- Confirm whether your supply chain sourcing may be exposed to a potential limited exclusion order or cease-and-desist orders.
