What this means
Status 702 means the registration is active, Section 8 was accepted, and a Section 15 declaration of incontestability was also accepted. Incontestability strengthens your rights by limiting certain challenges after five years of continuous use. Continue use in commerce and plan for the 10-year Section 8 and 9 renewal.
