Contrary to popular belief, basic trademark rights are established by use in commerce, not by registration. This means that as soon as you have a name, slogan, design or combination of these that you are using to identify the sale of your goods or services, you have a trademark and you have rights associated with your trademark. The rights that you get by simple use of your trademark, is called common law protection, and the rights associated with common law protection are very limited in strength and scope.
Making the decision to then register your trademark, gives you enhanced rights that span the entire United States, and can serve as a springboard to international protection. One of the most valuable assets a business controls is its brand, and seeking full protection of your brand name should be a priority and is a true key to the success of any business.
