Taylor Swift is getting down to business again: having hit the business pages last year by spurning Spotify, this week the pop star showed her savvy again by trademarking a range of phrases and images from her latest album.
The filings mean that from now on, no-one else can make T-shirts, tote bags, lanyards or even walking sticks bearing the legend "This Sick Beat". Similarly, she's trademarked phrases such as "Cause We Never Go Out of Style" and "Could Show You Incredible Things". She also has trademarks on her initials (no one tell TS Elliot), as well as her signature.
