European Union’s case that it filed in January 2009, against Microsoft has got another supporter in form of Google. Google has confirmed that it wishes to join EU in the antitrust case against Microsoft regarding Internet Explorer, the famous web browser of Microsoft.

The case filed by EU in January has accused Microsoft of killing competition when it comes to browsers by putting Windows and Internet Explorer together. EU filed the case after a formal complaint from Opera, another web browser developer. Mozilla which makes the famous Firefox browser also joined the case against Microsoft.

Google believes that the fact that IE is coupled with the Microsoft Operating System Windows which dominates the market, gives IE an unfair advantage. This causes innovation for users to be held back.

This isn’t the first time that Google has been a part of an antitrust claim against Microsoft. Google earlier went against Microsoft in 2006 complaining that Microsoft is driving users to its search service unfairly using IE. Google also went against Microsoft’s acquisition of Yahoo in 2008 which later fell apart.

Microsoft also has openly opposed the acquisition of DoubleClick by Google.
