Meghan Markle has suffered a legal blow after being denied the right to trademark 'Archetypes', the name of her award-winning podcast which launched in August 2022.The Duchess of Sussex, 41, and her team at Archewell Audio had applied to the United States Patent and Trademark Office (USPTO) for the trademark. But they were dealt a blow as the request was denied on the grounds of a "likelihood of confusion" due to another trademark with a similar name already being in existence.
