Pharrell Williams has filed a lawsuit hoping to get a court to rule that he isn't violating a trademark Will.i.am has on the phrase "I am." Will.i.am has been sending Pharrell letters demanding that the Pharrell-founded site iamother.com quit using "versions of the phrase." Reuters reports that "trademarks owned by Williams's company, I Am Other Entertainment, do not have periods between the 'i' and the 'am,' while those owned by will.i.am do." Not a good look, guys. It's two words. Common ones. You're both famous. Wrap it up.
