Apple, Samsung, and Google face US import ban threat over spatial audio patents
A US trade agency has opened a formal investigation into Apple, Samsung, and Google over alleged spatial audio patent infringement — and the remedy being sought isn't just money. If the complainant wins, entire product categories could be banned from US ports.
The case was triggered by BoomCloud 360, a California-based audio processing company that filed a complaint on August 14, 2026. The US International Trade Commission formally instituted investigation 337-TA-1521 on September 16. BoomCloud — which has raised around $6.72 million in funding and holds 44 patents — claims the three companies have been importing and selling devices in the US that use its technology without a license. Three patents are at the center of the dispute, covering spatial audio enhancement, crosstalk cancellation, and gain adjustment for audio processing.
The ask
BoomCloud isn't seeking damages in the traditional sense. It wants a Limited Exclusion Order — a tool that, if granted, blocks named products from entering US customs entirely. Alongside that, it's requesting cease-and-desist orders that would halt sales and marketing of any infringing devices already in the country. It's an aggressive posture, but not without precedent: a similar USITC battle between Apple and medical tech firm Masimo led to Apple Watch models being briefly pulled from shelves in late 2023.
How this plays out
The investigation goes to an administrative law judge, who will conduct a full hearing and issue an initial determination on whether Section 337 of the Tariff Act of 1930 has been violated. From there, the timeline runs roughly as follows: the Commission sets a target completion date within 45 days of institution; the full Commission can then review the judge's ruling; and if a violation is confirmed, the US Trade Representative gets a 60-day window to override the order on public policy grounds. Start to finish, ITC investigations typically wrap up in 12 to 18 months — years faster than equivalent federal court litigation.
The specific device models at risk haven't been disclosed. Given that the patents cover core audio processing functions, the exposure could extend across current flagship smartphones, tablets, and earbuds from all three companies. Apple, Samsung, and Google have each filed parallel declaratory judgment lawsuits in federal court — standard defensive moves in dual-track patent disputes, but expensive ones.
What's next
BoomCloud 360 is a relatively small player taking on the three biggest consumer electronics brands simultaneously, which is unusual even by ITC standards. The investigation is ongoing, and no ruling is imminent. But the clock is now running — and for anyone who bought, or plans to buy, a flagship phone in the US, it's worth watching.
