San Francisco officials have filed a motion against Oakland International Airport to stop using "San Francisco Bay" in its name, claiming travelers have confused the recently renamed East Bay airport with SFO.

San Francisco's city attorney filed a preliminary injunction in federal court on Tuesday asking a judge to tell the Oakland airport to immediately stop using its new name, claiming it violates a trademark infringement.

With October around the corner, the Phillies, Astros and Padres appear locked in, while other teams have questions to answer.

San Francisco is petitioning a judge to immediately stop Oakland from using its new "San Francisco Bay Oakland International Airport" name, saying that it is a trademark infringement on SFO and is causing some to show up at the wrong airport.

After Oakland changed the name of its airport earlier this year, San Francisco’s city attorney on Tuesday asked a federal judge to block the change as part of a trademark infringement lawsuit.
