Google must face trial over Sonos patents, says California judge

Alphabet’s Google received a mixed ruling from a San Francisco federal judge in a patent lawsuit brought by Sonos Inc over wireless audio technology, failing to invalidate all of the patents before a trial but narrowing Sonos’ claims.

The case, set for trial May 8, is part of a contentious intellectual property dispute between the former business partners over their smart speakers that includes lawsuits in the United States, Canada, France, Germany and the Netherlands.
