A registered extension of protection of a trademark in the United States is a trademark that is registered with the United States Patent and Trademark Office (USPTO) under Section 66(a) in accordance with the Madrid Protocol. The registered extension of protection is treated almost identically to a trademark that is registered under Section 1(a) (use in commerce) or Section 44(e) (U.S. registration based on a foreign trademark registration) with only a few very minor exceptions. In other words, essentially all of the benefits and protections afforded a trademark registered under Section 1(a) or Section 44(e) equally apply to a trademark registered under Section 66(a).
