About Charles

Learn Charles’s areas of practice.

Trademark Law is my Passion! I have over 20 years experience in the space. My goal for a client is to register their trademark in the least amount of time, for the least amount of cost, with the highest chances of getting the trademark application or logo registered. Part of my workflow is to educate the client about trademark and intellectual property law. This gives the client confidence when moving forward with their branding goals. As part of the consultation we inform you of the potential issues with applying for the trade mark, and we plan in advance to avoid them. Noone likes surprises, and we do our best to provide insight as to what can happen with your trademark application. We've been down the trademarking path many times. Let us guide you through the registration process.

Assistance with Trademark Process
Upon initial contact of Mr. Riddle, I received an almost immediate, same day response directly from him and not a subordinate. Mr. Riddle answered all of my questions and demonstrated his obvious knowledge and familiarity with the Trademarking process. I was provided with specific directives and even made aware of potential hurdles I could encounter in my attempts to secure my Trademark. I would definitely recommend anyone looking to embark on a similar path to contact Mr. Riddle.
