What is the difference between a registered and unregistered trademark?
Registration of a trademark is analogous to how a deed works to prove ownership of real property. The registration guarantees the registrant’s exclusive right to use the trademark and a registration, therefore, gives a trademark certain legal presumptions of ownership and strength under the law. Strength of a mark involves how recognizable the mark is in the marketplace and is an important factor in proving trademark infringement against a defendant.
A trademark registration is considered direct and prima facie evidence of exclusive ownership. It enables the registrant to more easily fend off a challenge to the ownership or prior use of a trademark because it shifts the burden to the party contesting the owner’s registration.
A federal registration, however, is not required to own a trademark. A party that uses a particular name for a company or product also has certain common rights to use a trademark, but common law rights do not carry the presumptive rights for nationwide use that come with a federal registration. It, therefore, is recommended that any trademark with value, or potential value, be registered with the USPTO.
