Microsoft is filing a formal complaint with the European Commission as part of the Commission's ongoing investigation into whether Google has violated European competition law, says Microsoft. In a blog, the company has outlined its reasons why. "Google has done much to advance its laudable mission to 'organise the world's information,' but we're concerned by a broadening pattern of conduct aimed at stopping anyone else from creating a competitive alternative," said Brad Smith, Senior Vice President & General Counsel, Microsoft Corporation. With that in mind Microsoft has joined "a large and growing number of companies registering their concerns about the European search market". Microsoft says that the European Commission reckons Google has about 95% of the search market in Europe. "This contrasts with the United States, where Microsoft serves about a quarter of Americans' search needs either directly through Bing or through our partnership with Yahoo!," added Smith.
