In the film, the protagonist is trying to adapt a fictional choose-your-own-adventure book called Bandersnatch into a video game. The lawsuit alleges that Netflix is using the phrase "choose your own adventure," which is a registered trademark of Chooseco, without permission. The movies' "dark and, at times, disturbing content" also tarnishes the Choose Your Own Adventure brand, the suit alleges.

"The use of Choose Your Own Adventure in association with such graphic content is likely to cause significant damage, impacting our book sales and affecting our ability to work with licensing partners in the future," said Shannon Gilligan, co-founder and publisher of Chooseco, in a release. "We have received an unprecedented amount of outreach from people who believed we were associated with the creation of this film, including parents who were concerned."
