SALT LAKE CITY — Salt Lake Comic Con lawyers have filed a motion for a new trial following a federal jury’s decision that the convention infringes on San Diego Comic-Con’s trademark.

The Salt Lake lawyers filed the paperwork on Tuesday in response to last month’s eight-day trial in U.S. District Court, during which jurors decided that the California convention’s trademarks are valid. The jury found that the infringement was not willful and awarded $20,000 in damages to the San Diego Comic-Con, which had sought $12 million.

The Salt Lake lawyers say evidence was wrongly excluded during trial and improper jury instructions undercut the evidence.

The case began in 2014 when the California convention sued; claiming the use of “comic con” in the Salt Lake company’s name infringes on its trademark and confuses the public.
