The Trademark Trial and Appeal Board (“TTAB”) affirmed the refusal of the United States Patent and Trademark Office (“USPTO”) to allow a Florida company to register trademarks containing the word “Keto.”  In its ruling, the TTAB explained that the term “Keto” is descriptive for dietary products, even when it is combined with the other words that made up the company’s trademark registrations.  With the popularity in Keto dieting and Keto products, this may serve as an informative ruling going forward.
