Quinn Emanuel Urquhart & Sullivan is facing a complaint filed Wednesday in a Manhattan federal court by a former secretary accusing the elite trial firm of racial discrimination and retaliation.

Spencer Marin, a former floating secretary who left Quinn Emanuel in 2015, claims that he was subjected to racial slurs by a trial logistics director during the high-profile 2014 Apple v. Samsung patent trial. Marin, who is black, also claims his work was more harshly scrutinized than other secretaries and that he was passed up for a promotion after he raised alarms about a co-worker’s behavior.
