April 13, 2017 - On behalf of its client, D1 Sports Holdings, LLC and its parent D1 Sports Parent, LLC, who owns U.S. trademark registrations and common law marks consisting of variations of the D1 mark for fitness-related goods and services, Marbury successfully defeated registration of the mark #D1BOUND, covering a variety of clothing items.  In its opinion dated April 13, 2017 (non-precedential), the Trademark Trial and Appeal Board agreed with D1 Sports that the mark #D1BOUND so resembled D1 Sports’ mark D1 “in appearance, sound, connotation and commercial impression” when used in connection with apparel and clothing, as to be likely to cause confusion.  In so ruling, the Board found D1 Sports’D1 mark “inherently distinctive.”  D1 Sports was represented by Marbury’s Shauna M. Wertheim and Timothy J. Murphy.
