Taylor Swift has been granted trademarks on a variety of phrases and words, including her name and "This sick beat".
Proving herself again as a canny business mind - her controversial Spotify pull netted her, or at least went some way to netting her, 1.28 million sales of 1989 - Swift's slapped a big ol' TM on some of her most memorable lyrics and other associated terms. The BBC seem to think this is because she wants to halt fraudelent merchandise with her famous words, but Swift's not officially divulged the reason.
You can peruse all Swift's recently granted trademarks here. They include various iterations of her signature, "Party like it's 1989", "Could show you incredible things", "Nice to meet you. Where you been?" and "'Cause we never go out of style".
So, if you were planning to mock up some TS "whips, harness and saddlery" - items specifically included, for some reason - then hard luck, Business Taylor has struck again.
Check out this sick beat™ from Swift.
