The San Francisco Chronicle reports the Giants and Major League Baseball never bothered to trademark the logo. In March, Gogo Sports of Hayward snatched the trademark, and started using the logo on its knockoff clothing.
The company is now suing the Giants in an effort to protect their right to use the logo. But the suit isn't expected to go far: federal law still protects unregistered trademarks and the logo is associated with the Giants.
