Watch your blog posts and tweets ladies and gentlemen, your words might just land you with a lawsuit for violating Taylor Swift's new trademark. As of today, Swift has officially trademarked the "Shake It Off" phrase "this sick beat" with the U.S. Patent and Trademark Office. It's just one of many 1989 expressions she's claimed as her own under the eyes of the law. Others include: "Party Like It's 1989," "Nice to Meet You. Where You Been?," and "Cause we never go out of style." The trademarks apply to everything from paper products, bath soaps, apparel, and non-downloadable content. It seems petty, but considering how little music sales actually bring in for artists nowadays, keeping a lock on merch is vital. Annoying but smart business move. Don't take her (and the government's) warning lightly when inscribing something on a T-shirt. She's got a blank space, baby, and she (or some lawyer) will not hesitate to write your name.
