It seems the war between Pharrell Williams and Will.I.Am is heating up after Pharrel decided to file a lawsuit against the Black Eyed Peas member because of accusations of violating trademarks.

The lawsuit started because Will.I.Am demanded that Pharrell stop using the ¡°I AM¡± on his I Am Other company as it closely resembles Will.I.Am¡¯s own brand name.

Pharrel has decided to take the battle to court, after saying that Will.I.Am¡¯s claim is very weak, because the trademark doesn¡¯t resemble the ¡°I.Am¡± on Will.I.Am, as it does not have the full stops in between.

Brad Rose, Pharrell¡¯s representative said that the court would see ¡°I Am Other¡± doesn¡¯t ¡°infringe, dilute or unfairly compete¡± with Will.I.Am¡±

This comes after Will.I.Am said he was going to sue Pharrell for using the trademark. His lawyer, Ken Hertz said that the musician ¡°has done what any trademark owner must do to protect and maintain a trademark¡±.

¡°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.¡±??

It could be jealously or not, but Pharrell has been dominating the charts lately with two massive singles that currently sit in the top two positions. His performance with Daft Punk on the techno smooth hit, ¡®Get Lucky¡®, alongside Robin Thicke¡¯s ¡®Blurred Lines¡¯ has seen the rapper enjoy a boost in single sales.

According to the Official Charts Company, those two singles, have helped Pharrell set a record for the most number of singles sold this year, after sales went up by 2.5% over the same time last year.
