Certain Magnetoresistive Random Access Memory (MRAM) Devices, Products Containing Same and Components Thereof; Notice of Institution of Investigation

📌 ETDETA brief — importer impact summary (educational)

Brief takeaway: The ITC has opened a Section 337 patent investigation into certain MRAM devices, which could eventually lead to import restrictions if a violation is found.

What changed: According to the notice, the ITC instituted an investigation based on an amended complaint filed by Avalanche Technology, Inc. alleging that imported MRAM devices, products containing them, and their components infringe certain claims of four U.S. patents. The notice states the complainant requests a limited exclusion order and a cease and desist order, though no such orders have been issued at this stage.

Who's affected: The notice names magnetoresistive random access memory (MRAM) devices, products containing them, and components thereof. It cites U.S. Patent Nos. 9,318,179; 9,419,210; 11,678,586; and 10,490,737. No specific HTS codes or countries of origin are stated in the notice.

What to review:
- Review whether your products include MRAM devices or components that could fall within the described category.
- Confirm with your broker or counsel whether any of the four cited patents may be relevant to your products.
- Check for future ITC notices or any exclusion or cease and desist orders that may result from this investigation.
- Confirm the identity of your suppliers and whether they have been named as respondents once that information becomes available.
