HOW LONG DOES A TRADEMARK LAST?
A common law trademark lasts as long as the mark is used in commerce. A trademark registered with the United States Patent & Trademark Office is registered for ten year periods, provided that the owner filed a declaration of use between the fifth year and continuation statement prior to the end of the ten year period. As long as these requirements are met, the trademark will retain the rights granted it by federal registration indefinitely. The longest running registration dates back to the 1890's.
