A months-long challenge to Banksy’s trademark on his well-known image of an ape has ended. A European Union board of appeals has overruled a decision by the EU’s Intellectual Property Office (EUIPO) which pronounced the shadowy British artist’s EU trademark on the spray painted monkey to be “invalid in its entirety,” The Art Newspaper reported Wednesday.

The kerfuffle began when the greeting card company Full Colour Black formally opposed the trademark in November 2019, alleging that it was filed in “bad-faith” and that the work was not distinctive. Pest Control, Banksy’s authenticating body since 2008, had filed a trademark for the image in 2018, which was subsequently registered in June the next year.
