As seen above, trademark applications for SWIFTMAS, BLANK SPACE, AND I'LL WRITE YOUR NAME, A GIRL NAMED GIRL, and 1989 were filed on that date.
Why are there multiple applications for the same trademark? TAS Rights Management filed each trademark in a different class of goods and services. For example, one SWIFTMAS application related to music services and live concerts while another related to various clothing and apparel. Because trademarks are divided into classes of goods and services, the same trademark is sometimes found on multiple applications.
Each of Taylor's trademarks filed on December 3rd relate to a variety of goods and services, including live music performances, clothing, printed materials (i.e. books, magazines, brochures), websites, and online retail services. All of these trademark applications were filed on an intent to use basis, which means Taylor Swift is not yet using these trademarks in relation to the underlying goods/services (which is surprising considering some of the marks filed).
This mass filing comes weeks before Christmas and is probably designed to protect primarily a variety of Taylor Swift apparel and merchandise during the holiday season (and thereafter). Merry SWIFTMAS everybody.
