We have to give credit to iHeartRadio for calling this trademark story “a game of cat and mau5.”
Electronic music producer and DJ deadmau5 (a/k/a Joel Zimmerman) has a cat named Prof. Meowingtons, PhD (“Meowingtons” for short). Prof. Meowingtons is reportedly the only animal with a verified Twitter account and it boasts nearly 31,000 followers. The cat’s name has been used as the name of a deadmau5 tour (the Meowingtons Hax Tour), on deadmau5 merchandise and album covers, and even on a line of headphones for cats (yes, you read that correctly).
Although the Meowingtons name has been in public use since 2010, Zimmerman didn't move to file a trademark for his cat's name until 2015. The USPTO rejected Zimmerman’s application since a Meowingtons trademark is already owned by a woman named Emma Bassiri who runs a website called meowingtons.com that sells cat-themed merchandise.
