Juice Generation applied to the Patent and Trademark Office to register a mark consisting of “PEACE LOVE AND JUICE” and a design for use with its juice bar services. GS Enterprises opposed the application on the ground that Juice Generation’s mark was likely to cause confusion with its own family of marks, all of which contain the phrase “PEACE & LOVE” and are registered for use with restaurant services. The Trademark Trial and Appeal Board sustained the opposition and refused to register Juice Generation’s mark. We conclude that the Board did not adequately assess the weakness of GS’s marks and did not properly consider the three-word combination of Juice Generation’s mark as a whole in comparing it to the two-word combination in GS’s marks. We therefore remand for further proceedings.
