What is a Statement of Incontestability in trademark law in the USA?

A Statement of Incontestability is a declaration by the owner of a trademark registered on the Principal Register, confirming the mark's validity and registration. It asserts the trademark owner's exclusive right to use the mark for specific goods and services. For a trademark to be considered "incontestable," it must have been continuously used in commerce for at least five years after registration and must still be actively used when filing the Statement of Incontestability.
