Josh Ellis, CSNPhilly.com; Two Phillies had their nickname jerseys denied because of copyright issue

[Kip Currier: Trademark law is the issue with the nicknames; not copyright law.]

"According to Matt Breen of Philly.com, two players, Zach Eflin and Hoby Milner had their nickname requests denied due to trouble with copyrights. Eflin was hoping to be known as “Led Zeflin” and Milner wanted to use the Force as “Hoby Wan Kenobi.”

Neither player was listed on the Phillies.com article displaying the nicknames the players on the team selected."

STEPHEN J. NESBITT, Pittsburgh Post-Gazette; Davehuman? Pirates had a hoot picking nicknames for alternate uniform

[Kip Currier: Trademark law is the issue with the names, rather than copyright law.]

"Chad Kuhl wanted “Kuhl Whip” but that, as was the case with many players’ first choices, was scotched by the league, presumably for corporate and copyright reasons. Kuhl went instead with “Chet,” the nickname given to him by fellow starter Trevor Williams. Williams wanted to be “Ved,” a nod to the Pearl Jam lead man, but was turned down and settled for the initials “EV.”"
