Estimated reading time: 7–10 minutes
The U.S. International Trade Commission (Commission) has announced its decision to review a final initial determination (FID) regarding certain Wi-Fi routers, Wi-Fi devices, mesh Wi-Fi networks, and related components. This investigation, identified as No. 337-TA-1454, was prompted by a complaint from Estelgia, LLC.
Investigation Background
The investigation originated from a complaint launched by Estelgia, LLC of Dover, Delaware, on June 23, 2025. The complaint alleged violations of section 337 of the Tariff Act of 1930. Estelgia claims that certain Wi-Fi products infringe on several U.S. patents, including patents numbered 7,936,714; 11,246,016; 10,735,973; 10,531,518; 9,775,164; and 9,277,591.
Respondents in the Investigation
Initially, the investigation named seven respondents. These included Linksys Holdings, Inc. and Linksys USA, Inc., ASUStek Computer Inc. and ASUS Computer International, D-Link Corporation and D-Link Systems, Inc., and Plume Design Inc.
The Commission settled with the Linksys Respondents on December 19, 2025. The D-Link Respondents later terminated their involvement on April 27, 2026, through a consent order.
Key Findings and Review Points
On August 6, 2026, the administrative law judge (ALJ) issued an FID which found violations of section 337 by ASUS and Plume. Following this, various petitions for review were filed. The Commission has determined to review the FID partially.
The focus of the review includes:
- The interpretation of claim 13 of the ‘714 patent.
- Indirect infringement by ASUS of claim 13 of the ‘714 patent.
- Infringement claims related to the ‘973 patent.
- Written description and obviousness of the ‘973 patent.
- The economic aspects of the domestic industry requirement.
Commission’s Requests and Extensions
The Commission requests further written submissions from involved parties and interested agencies regarding the issues of remedy, public interest, and bonding. The target date for the completion of the investigation has been extended to January 14, 2027.
Submission Guidelines
The Commission encourages written submissions from parties and third parties on the questions identified. Complainant Estelgia is asked to identify the desired remedies and submit proposed orders. Initial submissions are due by November 12, 2026, with replies due by November 19, 2026.
Public Interest and Remedies
The Commission is assessing the implications of potential remedies, such as exclusion orders or cease and desist orders, on public health and welfare, competitive conditions, and U.S. consumers. Submissions concerning these public interest factors are encouraged.
Conclusion
The Commission’s decision will consider the full spectrum of legal and economic factors before deciding on any remedies. Determinations will take into account statutory requirements, party submissions, and public interest considerations. The outcome of this investigation could significantly impact the U.S. market for Wi-Fi devices and technologies.
