The star is likely to apply the phrases to her own range of merchandise.
Pop star Taylor Swift has trademarked phrases including "this sick beat" and "we never go out of style", in the United States.The phrases are all lyrics from her current album, 1989, which has sold more than 4 million copies in the US.
The trademark ruling prohibits others from using her lyrics on items such as t-shirts, stickers and bags.
Other phrases covered by the ruling include "nice to meet you, where you been" and "party like it's 1989".
Her name, signature and initials have also received trademark protection.
Although the application may seem trivial, printing lyrics onto merchandise is an increasingly important revenue stream for musicians in an era of declining record sales.
