A would-be challenger to Google Inc. said Tuesday it is suing the Internet search leader for alleged abuses that include illegally rigging its prices to thwart potential competitive threats.

In a 38-page page complaint, TradeComet.com LLC accused Google (nasdaq: GOOG - news - people ) of manipulating its system for setting ad rates to make it too expensive for a specialty search engine called SourceTool to promote itself within Google's vast online marketing network.

In a press release, TradeComet said it filed its antitrust lawsuit in a New York federal court.

Google said it hadn't reviewed the allegations as of late Tuesday, but the Mountain View-based company reiterated its belief that there are plenty of other online advertising options, including networks run by rivals Yahoo Inc. (nasdaq: YHOO - news - people ) and Microsoft Corp. (nasdaq: MSFT - news - people )

"As we have consistently made clear, the advertising market in which Google operates is highly competitive, and advertisers have a huge range of choices," Google said in a statement.

TradeComet's lawsuit is the latest legal action to allege Google has used its widening market power to create a monopoly that enables it to bully rivals or squeeze out Web sites that it doesn't like.

Google processes nearly two-thirds of the Internet search requests in the United States and sells an even larger chunk of the text-based ad links that appear alongside search results and other content on millions of Web pages served up each day.
