Representative Matters

Showing of
Foley’s Sports Industry Team has worked closely with Citigroup on multiple representations, including sponsorship of the 2012 London Olympics and the 2014 Sochi Olympics. In this respect, Foley was instrumental in navigating them through the various branding, copyright, right of publicity and marketing/advertising issues that arise through the sponsorship of an event of this magnitude on an international stage. When it comes to trademarks and sports, the Olympics and Citigroup are paramount. Given the numerous well-known Citi-formative marks and brands in more than 100 countries, this is a global representation. Citigroup’s confidence in Foley is demonstrated time and time again in sports, including through our branding/trademark and advertisement counseling in connection with the Citi Bike Program (the successful bike sharing program in New York City), Citi Field (where the NY Mets play baseball) and the sponsorship of various sporting events for children, such as the Citi Open.
Foley regularly provided global strategic counseling, reviewed advertising and marketing materials regarding copyright and right of publicity issues directly with Citigroup's in house trademark and advertising counsel and various associated business units regarding Citigroup's 200th anniversary.
Foley assists new client DirecTV with various trademark counseling, enforcement and social media matters.
