A meeting between Tim Cook and Steve Mollenkopf a year ago at Apple Inc.'s headquarters started with a tense moment.
The feuding leaders of two smartphone industry titans — Apple and Qualcomm Inc. — were there to discuss a long-simmering patent dispute. Mr. Mollenkopf, who suspected Apple of supporting a hostile takeover of his company, initially didn´t speak, leaving his general counsel to start talking, according to people familiar with the meeting.
