Italy has a very high threshold-of-originality standard. Hogan Lovells states that "In summary, the threshold for an industrial design product to enjoy copyright protection is still quite high and even famous industrial design products have been denied such protection by Italian Courts." This likely also applies to logos. For example, the logo of A.C. Milan is not copyrighted. See COM:CRT/Italy#Threshold of originality for more information.
