BRUSSELS -- Google made a second try last week to settle a three-year-old antitrust case with the European Union, officials said. Neither side released details of the offer, however, and rivals continued to call for the American technology company to cede more control of its Internet search and advertising business.
The latest offer by Google was acknowledged in Italy on Sunday by Joaquín Almunia, the European Union's competition commissioner. Mr. Almunia has been seeking a settlement with the company since the early stages of the case, which formally began in 2010. The case revolves around claims that Google has abused its dominance in the Internet search and advertising field by, among other things, favoring its own products and services in search results. Google powers 90 percent of searches in many European markets; its share in the United States is closer to 70 percent.
"Once we have completed our analysis, once we will check that these new proposals are able to eliminate our concerns, we will tell Google what to do," Mr. Almunia, referring to the offer, said in an interview with Bloomberg Television.
Mr. Almunia is under mounting pressure from Google's rivals seeking to prolong its legal entanglements in Europe and toughen the terms of any deal.
In July, he was forced to reject a preliminary settlement struck with Google after industry groups complained that aspects of the deal could strengthen, rather than loosen, Google's hold in Europe. That proposal, the result of Google's first offer of a settlement, would not have required the company to change the algorithm, or formula, that produces its search results. But it would have been the first time Google had agreed to legally binding changes to its search results, and it went much further than the minor concessions it made to settle a case before the United States Federal Trade Commission.
The latest proposal by Google addressed Mr. Almunia's "areas of concern," Al Verney, a spokesman for the company in Europe, said on Monday. "We continue to work with the commission to settle this case," said Mr. Verney, who declined to describe the contents of the offer.
Mr. Almunia said over the weekend that he would prefer a swiftly negotiated settlement with Google because that would be a better way of regulating the fast-moving technology sector. But he said he could still issue formal charges against the company if a deal failed to materialize.
With the case still open, Google faces a serious challenge in Europe, where it risks far-reaching orders demanding it change its business practices and potentially a fine of up to $5 billion.
Leaders of industry groups said that the latest offer by Google should be carefully tested in the marketplace to assure that the remedies addressed complaints that the company favored its own products in search results.
"We must hope after so much prevarication that this time Google's proposals represent a genuine attempt to address the concerns identified," said David Wood, the legal counsel for Icomp, an industry group backed by Microsoft and a number of other companies. The previous proposals were, he said, "manifestly defective."
