San Diego Comic-Con is taking Salt Lake Comic Con to trial in federal court after negotiations between the two pop-culture conventions failed.
Bryan Brandenburg, co-founder of the Salt Lake event, confirmed Thursday that they were unwilling to give the much older and bigger San Diego Comic-Con what it wanted out of the negotiations. San Diego sued Salt Lake last year in U.S. District Court for the Southern District of California for trademark infringement, alleging that Salt Lake's name was too similar.
A trial date has not been set.
A deal could still be reached before the trial, but Thursday's development represents a significant shift in the parties' talks, particularly in light of the recent positive statements from Salt Lake Comic Con co-founders.
