Band Name Registration Challenge
Thaddeus Tran sought to register a mark for his Asian-American rock band that some found offensive. The examiner refused registration on the ground that the mark disparaged a group. Because the mark constituted Tran's own private expression rather than government speech, the refusal could not stand under the First Amendment.
Franchise Royalty Dispute
Tyler Taylor operated a chain of ice-cream shops under a license from a national franchisor. When the franchisor sued for unpaid royalties, Taylor demanded a jury trial on the trademark issues.

Can a mark lose its status as a true trademark through government involvement?+
No. Even when the PTO examines or registers a mark, the mark remains the registrant's private speech and does not become government speech.
