The European Commission, which is on track to become Microsoft's sole nemesis, has opened two more investigations into "claims that the company has abused its dominant position to squeeze competitors out of the market", according to the New York Times (opens in new tab).
The first one follows a complaint by Opera, a Norwegian company which produces an eponymous browser, rival of Microsoft's own Internet Explorer; The EC will examine whether Microsoft's bundling of IE with Windows did harm Opera or not.
Opera has a non-negligible presence in the mobile market while its share of the desktop browser market is insignificant.
The Norwegian company filed a complaint (opens in new tab) on the 13th of December 2007 against Microsoft and it took only one month for the EC to react.
The second inquest will look at whether Microsoft is refusing access to data and codes that rival companies need in order to make their products compatible with Microsoft's Office suite - which includes Word, Excel, Powerpoint.
The two new investigations come four months after the Court of First Instance, Europe’s second highest Court of Justice, upheld the commission’s 2004 decision to impose fines on Microsoft.
