Asked if he had received Google's proposal to resolve the matter, EU Competition Commissioner Joaquin Almunia told Reuters: "Yes."
He declined to provide details on the proposal, adding only: "We are analyzing it."
The Commission, which acts as competition regulator in the 27-member European Union, is now expected to seek feedback from Google rivals and other interested parties.
Almunia said in December he was giving Google until this month to present a comprehensive offer to allay regulatory concerns and stave off a possible fine, which could be as much as 10 percent of global turnover if a company is found to be in breach of EU rules.
The Commission has said Google may have favored its own search services over those of rivals, and copied travel and restaurant reviews from competing sites without permission.
The EU executive is also concerned the company may have put restrictions on advertisers and advertising to prevent them from moving their online campaigns to competing search engines.
Earlier this month, Google won a major victory when U.S. antitrust regulators ended their investigation, saying the company had not manipulated its web search results to block rivals.
