After further review, the U.S. Patent and Trademark review board's decision stands.

A federal appeals court rejected South Carolina's petition to use the letters "USC" on the Fighting Gamecocks baseball team's uniforms. The decision upholds the Patent and Trademark Office board's ruling regarding the University of Southern California's claim to the logo.

Scott Edelman, an attorney representing USC, -- the LA USC -- said the ruling protects the school's "primary athletic mark." He said the logo, used on team clothing and equipment, brings in significant revenue.

Nobody would confuse a Trojan for a Gamecock, but he said people might mistake South Carolina merchandise for Trojan merchandise if the garnet-and-black of South Carolina and the cardinal-and-gold of Southern California both carried the same "USC" logo.
