Pharrell Williams files lawsuit against

Musicians are at war over copyright of the phrase "I Am"

Pharrell Williams has filed a lawsuit against The Voice coach after he was accused of violating trademarks owned by the Black Eyed Peas member.

According to BBC Newsbeat, the lawsuit reveals that has demanded that Pharrell stop using the phrase “I AM”, a reference to his I Am Other company, on his websites. Labelling’s trademark as “relatively weak”, the lawsuit explains that Pharrell’s trademarks do not feature full stops between the I and the am, while’s do.

Pharrell’s representative Brad Rose has asked that the court confirm that “I Am Other” doesn’t “infringe, dilute or unfairly compete” with has previously denied reports that he was suing Pharrell for the use of “I Am”, saying that he “has done what any trademark owner must do to protect and maintain a trademark”, through his lawyer, Ken Hertz. “We think their proposed trademark is too close to our registered and common law trademarks. They disagree. We hope to work out a sensible compromise that will allow both parties to move forward without unnecessary acrimony.”

Meanwhile, Pharrell Williams appears on the top two best-selling singles of 2013, according to the Official Charts Company. Purchases of single tracks are up 2.5 percent on the same period last year, which set the record for the most number of singles sold. This year’s figures are helped by the strong performance of ‘Get Lucky’ by Daft Punk featuring Pharrell Williams and Nile Rodgers, which has sold over a million copies, and Robin Thicke’s ‘Blurred Lines’, which also features Pharrell, selling more than 828,000 copies.
