Information in this article has been pulled from a brochure printed by the Phoenix Public Library. The full document can be found here.A trade name is a name used to identify organizations, and generally their products and services as well. A trademark is any word, phrase, design, slogan, or symbol, which distinguishes certain products and services from those offered by competitors, such as "Jell-O" or "Kleenex". Although trademarks registered with the state and/or federal governments enjoy the highest degree of protection, even unregistered or "common law" trademarks may be somewhat protected.
Following the steps below may help you find potentially conflicting trade names and trademarks. Each step offers a higher degree of protection.

particular emphasis on Arizona businesses. This check will take about 30 minutes. - Check your proposed name on the Arizona Secretary of State’s database at
