Before adopting, using, and applying to register your trademark, it’s good practice to perform a comprehensive federal trademark search in order to help minimize the risk of being sued for trademark infringement by someone who owns prior rights in an identical or confusingly similar trademark. Furthermore, a federal trademark search will assist you in determining whether the name, slogan, or tagline you want to use is eligible for registration with the United States Patent and Trademark Office (USPTO).
Although you can (and should) hire a trademark attorney to conduct your trademark search and provide you with a legal opinion as to whether your mark is available for registration, another option is to perform the search yourself using an online trademark search engine, such as the one offered by Trademarkia.
However, please allow me to demonstrate why using the Trademarkia search engine has tremendous potential to lead you astray and completely waste your time and hard-earned money.
