Cleveland Metroparks Zoo is suing the Pittsburgh Zoo in federal court over the upcoming Asian Lantern Festival in August.

The Cleveland zoo says that the Pittsburgh Zoo does not have the right to use the phrase “Asian Lantern Festival.” They are claiming that they own the trademark to that particular wording after kicking off an “Asian Lantern Festival” with Tianyu Arts & Culture, Inc. in 2018.

Cleveland Zoo says in the suit that Pittsburgh Zoo officials are using the Asian Lantern Festival name without permission, and potentially confusing visitors of both attractions.
