Please refer to this post as: , ‘Trademark case: Cai v. Diamond Hong, Inc., USA’, Kluwer Trademark Blog, September 4 2018,

The Trademark Trial and Appeal Board did not err when it found that the WU DANG TAI CHI GREEN TEA mark was confusingly similar to the registered mark TAI CHI, according to the U.S. Court of Appeals for the Federal Circuit. The Board’s findings as to the DuPont factors were supported by substantial evidence, in the court’s view. In addition, the Board did not err in excluding evidence that the applicant sought to introduce in a reply brief (Cai v. Diamond Hong, Inc., August 27, 2018, Wallach, E.).
