By Blake Brittain(Reuters) - Alphabet's Google received a mixed ruling on Thursday 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. Google spokesperson José Castañeda said in a statement the company appreciated the decision to invalidate one of Sonos' patents and that Sonos "misrepresented our partnership and mischaracterized our technology. Alsup also said he would hold a separate bench trial after the jury trial to determine whether Google's redesigned speakers infringe Sonos' patents
