In 2015 when Apple Music decided to take the first steps into the streaming business, they began the process of registering the trademark for the same name. However, in 2016 Bertini opposed the trademark registration in the US because he had been using the name "Apple Jazz" in shows and various musical projects since the 1980s.
Bertini argued that Apple Music was too similar to Apple Jazz and that the two names would cause “consumer confusion.” Since the use of Apple Jazz pre-dated Apple Music’s application, it seemed that Bertini had a good case for the opposition. The heart of the case is who had first use of the “Apple” name in relation to music.
