Alphabet Inc’s arguments draw skepticism from judge in ad tech case

A federal judge threw cold water on one of Alphabet Inc.’s key arguments in a Department of Justice lawsuit over allegations that Google monopolised advertising technology.

During closing arguments in the lawsuit against the tech giant, US District Judge Leonie Brinkema said that she disagreed with Google’s attempts to rely on an earlier antitrust case involving American Express Co. The judge interrupted Google’s lawyer Monday to say that she had carefully studied a 2018 Supreme Court decision in the older case.
