The search giant's latest concessions to settle the dispute are seen as a positive step by the European Commission.
Federal regulators scrutinizing Google may not have a strong enough case to file a lawsuit targeting the company's search service, Bloomberg reports.
After complaints from European companies about their search rankings, regulators are seeking information on how Google's secretive search algorithms work.
Attorney General Greg Abbott has asked Google for information regarding the complaints of several companies that Google is penalizing them in search results.
The U.S. Federal Trade Commission will apparently delay its decision over Google's antitrust probe until 2013, and the search giant could settle with EU authorities as soon as January.
The EU competition commissioner Joaquin Almunia says the case is "complex" and his office is in no hurry to decide if it should launch a formal antitrust complaint against Google.
The European Commission is said to be readying a lengthy Statement of Objections against Google for abusing its market dominance in Web search.
Google offers to label its own services in search results and give some prominence to rivals. European competitiveness regulators now want feedback, and critics are lodging objections.
The state attorney general has demanded the search giant turn over a broad range of documents as part of an antitrust review.
Last November the European Commission opened a formal investigation of Google's business practices on that continent, and talks at resolving the matter have reportedly begun.
