Join us  September 17th at the New York Grill in Ontario.

Learn about how Trademark law impacts your marketing & branding efforts.



Co-presented by Gary J. Nelson, and Constantine “Gus” Marantidis, partners in the Glendale, CA office of Christie, Parker & Hale, LLP. 

The presentation is designed for non-trademark attorneys, and anyone involved in industries where branding is important, and anyone involved in the working at the intersection of marketing and brand awareness.  This will be an engaging talk that will provide you with the basics in Trademark law and what you need to understand to best serve your business and clients.

  • What is a Trademark?
    • Likelihood of confusion
    • Descriptiveness
    • Proper/improper specimens
    • Unregistrable subject matter
    • Disparaging material
  • Get a better understanding of: 
    • Problems with likelihood of confusion between trademarks and related goods & services
    • Challenges with descriptiveness. While a descriptive trademark may be a great domain name, it is not necessarily a strong and easily enforceable trademark
    • The interplay of one’s own trademarks and the trademarks owned by one’s competitors
