Taylor Swift is trying to trademark the word 'Swiftmas'.
The chart-topping singer is attempting to protect the word which has come to be used to describe her random acts of kindness, while she is also seeking to trademark '1989', the year of her birth and the title of her latest album.
The documents were filed to the US Patent and Trademark Office on December 3 and follow on from Taylor's efforts earlier in the year to trademark the phrases 'This sick beat' and 'Nice to meet you, where you been?'.
Documents show that four trademark applications have been launched each for 'Swiftmas', 'Blank Space', 'And I'll write your name' and 'A Girl Named Girl'.
The latter expression relates to a novel Taylor penned when she was just 14.
The book is reportedly in the care of her parents and as yet, Taylor has shown no ambition to publish the work.
Assuming the trademark applications are successful, rival performers will be prevented from using the phrases in a wide range of contexts, including on-stage performances, on clothing, merchandise and consumer goods, as well as on stationary, in books and in publications.
