plan would also add a second tower to the Hilton Bayfront hotel, adding 500 rooms adjacent to the Convention Center. Due to the proposed expansion of the convention center, Comic Con extended its contract for San Diego to 2016. In 2014, convention center expansion was halted due to a lawsuit. As of July 2015, convention center expansion is effectively frozen, partly because the city no longer has financing lined up for it (any financing plan would involve taxpayer money and would have to be approved by a public vote), and partly because the city lost the rights to the only contiguous parcel of land where expansion could occur. Other cities, including Los Angeles, began to seek to have Comic-Con move out of San Diego; In 2015, Comic-Con entered into negotiations with San Diego.

Police later stated that the teenage girl was injured in a fall; the arrested individual was released without any charges. Trademark In 2014, San Diego Comic-Con sent a cease and desist order to the organizers Salt Lake Comic Con, asserting that "Comic-Con" and "Comic-Con International" were registered trademarks of the convention, and that use of the term "comic con" in any form was trademark infringement as it implies an unauthorized association with San Diego Comic-Con. A U.S. court ruled in favor of San Diego Comic-Con and awarded $20,000 in damages (albeit not considering the infringement to be willful). Phoenix Comiccon changed its name to Phoenix Comic Fest as a proactive move to avoid possible legal issues in the wake of this ruling. They then filed a motion in an Arizona Federal Court to strike down San Diego Comic Convention's trademark In 2017, the Salt Lake Comic Con changed its
