ITC & Patent Litigation Briefing: Smart Locks, Wireless Earbuds, and Robotic Vacuums in the Crosshairs

Two active Section 337 investigations and a serial patent plaintiff highlight compliance risks for consumer-electronics exporters this week.

Active ITC Investigations: Smart Locks and Wireless Earbuds

Two Section 337 investigations remain active as of the week of July 29, 2026. Investigation 337-TA-9003 targets certain smart-lock devices and their components, while 337-TA-9001 covers certain wireless earbuds and components. No respondents have been publicly named in either case at this stage, but exporters and importers in these product categories should monitor Federal Register notices closely. An adverse finding in either investigation could result in exclusion orders barring infringing products from U.S. entry. Companies shipping smart-lock hardware or wireless audio products into the United States should proactively review their patent landscapes and consider requesting formal Customs rulings if exclusion orders issue.

Robotic Vacuum Case Settles — Lessons for Importers

Investigation 337-TA-9002, covering certain robotic vacuum cleaners, has been terminated following a settlement between the parties. While the terms of the settlement are not public, terminated-by-settlement outcomes often include licensing agreements or supply-chain modifications. For robotic vacuum exporters not party to this case, the investigation's existence signals that patent holders are actively policing this space at the border. Importers should conduct freedom-to-operate analyses before scaling U.S. shipments and watch for any consent-order conditions that could affect the broader market.

Serial Patent Plaintiff PatentHold LLC Targets Consumer Electronics in E.D. Texas

Outside the ITC, patent-assertion entity PatentHold LLC continues to pursue district-court litigation in the Eastern District of Texas, a historically plaintiff-friendly venue. PatentHold filed suit against Acme Electronics in January 2025 and against Beta Devices in November 2024. Both cases remain on the docket. Exporters whose products are distributed by or co-branded with either defendant should assess potential downstream exposure. More broadly, the pattern of sequential filings suggests PatentHold may expand its campaign to additional targets. Companies in the consumer-electronics supply chain should review their indemnification clauses and ensure they have litigation-hold procedures ready in the event they receive similar complaints.
