The U.S. Trade Judge ruled on Friday that Alphabet’s Google has infringed on five Sonos patents involving smart speakers and related technologies. This decision may lead to an import ban.
The brief ruling of Charles Block, the Chief Administrative Law Judge of the US International Trade Commission, did not explain why Google’s sale of these products violated the 1930 Federal Tariff Act, commonly known as Smoot-Hawley, to prevent unfair competition.
Sonos has been trying to prevent Google from importing home smart speakers, Pixel phones and other products from China.
Google did not immediately respond to a request for comment.
Sonos expressed satisfaction with the preliminary ruling, saying that the ruling “confirmed Google’s blatant infringement” and further efforts to defend its technology to prevent suspected misappropriation by larger competitors.
Sonos shares rose 11.4% in after-hours trading.
According to the committee’s website, Friday’s ruling will be reviewed by all ITC members, which is scheduled to take place on December 13.
According to regulatory documents, the ITC case is part of a series of lawsuits between the two companies, including cases in California, Texas, France, Germany, and the Netherlands.
Google has said that Sonos has sought help many times during the cooperation for many years, and finally integrated Sonos products into its Play Music service and Google Assistant software.
Some Sonos speakers use voice assist technology from Google and Amazon.com. Google’s own Nest smart speaker includes Google Assistant technology.
