The Section 8 Declaration of Use is a document filed with the United States Patent and Trademark Office (USPTO) for the purpose of maintaining a trademark registration. The Section 8 only applies to trademarks that are registered under Section 1(a) (use in commerce) or Section 44(e) (U.S. registration based on a foreign trademark registration). If your trademark is registered with the USPTO under Section 66(a) (registered extension of protection through the Madrid Protocol), then you would need to file the Section 71 Declaration of Use rather than the Section 8 Declaration of Use.
