Taylor Swift has made a mark on the world with her music, but she's also making waves with her trademarks.

The pop megastar has been on a trademarking tear, most recently applying for protection for the words and phrases “1989,” “Blank Space,” “And I'll Write Your Name,” “A Girl Named Girl” and “Swiftmas.”

“Blank Space” is the name of one Swift's singles, while “And I'll Write Your Name” is a line from that song. “A Girl Named Girl” is the title of a novel Swift published when she was 15 and “1989” is the year of Swift's birth and also the name of her top-selling latest album. “Swiftmas” is, well … who knows?
