By Foo Yun Chee BRUSSELS (Reuters) – Google has offered further concessions to address regulatory concerns about its search technology, the European Commission said on Wednesday, effectively settling a three-year investigation and avoiding a fine of up to $5 billion. The worlds dominant search engine has been the focus of a Commission investigation since November 2010, when more than a dozen complainants across Europe accused the company of promoting its own services at their expense. Google has now made three attempts to resolve the case, with the latest moves looking like they will be enough to settle it, although there will still be a chance for Googles competitors to provide further input. I believe that the new proposal obtained from Google after long and difficult talks can now address the Commissions concerns, European Competition Commissioner Joaquin Almunia said in a statement.
