FCSF, LLC filed each application in five different classes of goods and services, including "entertainment services, namely, soccer exhibitions rendered live in a stadium, and through the media of television and radio and the internet," soccer balls, apparel, magazines, computer software, and mobile applications. The company filed each application on an intent-to-use basis, which means the entity is not using these marks in commerce yet but has a bona fide intention to do so in the near future. This makes sense given a NASL soccer team is not currently operating in San Francisco.
According to the Empire of Soccer blog, subscribers to the group spearheading the effort to bring a NASL team to San Francisco received an email notifying them of the future club's name, San Francisco Deltas, on January 31st (just two days after the trademarks were filed).
According to my brief research, the NASL is a professional soccer league with 12 teams and is one league under Major League Soccer. The league has expanded rapidly in the past couple years, adding six teams between 2014 to the present. Most teams are located along the east coast of the United States with no teams being west of Edmonton. However, it appears that will change soon given these recent trademark applications.
