SAN JOSE — The question of whether Apple’s sweeping 2012 trial victory over Samsung entitles it to block its rivals’ sales of infringing products boomeranged back on Thursday to U.S. District Judge Lucy Koh.

Reconsidering Apple’s bid for a permanent injunction, Koh still seemed to question whether the company’s lawyers at Wilmer Cutler Pickering Hale and Dorr had demonstrated a sufficient connection between patented touchscreen features and consumer demand—an essential finding to issue the injunction.
