WASHINGTON — Google and federal officials are discussing a deal that would end nearly two years of investigation into claims of monopolistic behavior by the company without addressing the most serious claim — that it intentionally manipulates search results to harm competitors.
The talks between Federal Trade Commission Chairman Jon Leibowitz and top Google executives are focusing on less controversial issues, such as how the company uses patents and how it displays comments collected from other Internet services, said several people who were familiar with the talks and spoke on the condition of anonymity. They said that although allegations of search bias could reemerge should the talks collapse, they are not central to the discussions.
This development has angered a broad group of Google competitors and critics who have called on the FTC to engage in a high-profile legal battle against the search giant to curb its sprawling power in the digital economy, much as the Justice Department did with Microsoft in the 1990s. Some predicted that Congress or state attorneys general would pick up the issue of search bias if the FTC failed to act on it.
''The buzzards are circling for that, and there's just going to be massive resistance if they try to do that,'' said Silicon Valley attorney Gary Reback, who represents several companies that have complained about Google and also was involved in the fight against Microsoft. ''If a settlement were to be proposed that didn't include search, the institutional integrity of the FTC would be at issue.''
The FTC, which hired a prominent outside litigator to work on the case, declined to comment Wednesday.
Google spokesman Adam Kovacevich said in an e-mailed statement, ''We continue to work cooperatively with the Federal Trade Commission, and are happy to answer any questions they may have.''
Allegations of search bias turn on the increasingly complex way in which Google displays its results. Once focused mainly on helping users find useful links to other sites, the company's results now feature a heavy diet of paid content that appears in shaded sections at the top of screens and along the right-hand side.
A ''universal search box,'' also placed above traditional search results, often carries paid links to consumer products or flights — a function that directly competes with what once was a bustling, lucrative universe of specialized search companies such as Nextag and TripAdvisor.
In recent months, the search engine converted all of its shopping search links to paid results, which critics say hurts people seeking the best price or service.
