San Francisco is intensifying its legal battle against Oakland over the recent renaming of Oakland International Airport to 'San Francisco Bay Oakland International Airport.' City Attorney David Chiu has filed a motion for a preliminary injunction, citing traveler confusion and potential infringement on San Francisco's trademark for its airport. Since the name change, incidents have been reported where travelers mistakenly booked flights to San Francisco International Airport (SFO) instead of Oakland. San Francisco's lawsuit, initiated after Oakland's April decision, seeks to prevent the use of the new name, claim damages, and assert that Oakland's actions were designed to mislead travelers. Oakland officials argue that the name change was intended to enhance geographic awareness and have countered with claims denying trademark infringement. Mediation attempts between the cities have been unsuccessful, leading to the current legal proceedings set for a hearing on October 24.
