Hasbro (NASDAQ: HAS) announces that the iconic PLAY-DOH scent, known and loved by fans around the world, is officially recognized by the United States Patent and Trademark Office as a registered trademark of the brand. The trademarked scent, which Hasbro formally describes as a unique scent formed through the combination of a sweet, slightly musky, vanilla-like fragrance, with slight overtones of cherry, and the natural smell of a salted, wheat-based dough, makes the PLAY-DOH brand one of the few active and certainly most famous scent trademarks in the country.
