WILMINGTON, Del., Nov 10 (Reuters) - Technology outsourcing and consulting firm Accenture LLP asked a federal court on Tuesday to stop Guidewire Software Inc from selling its insurance software, which Accenture said infringes its patent.

Guidewire has been labeled one of the Silicon Valley Six, an elite group of private technology companies including LinkedIn that are likely initial public offering candidates.

Accenture said in a complaint filed in federal district court in Wilmington, Delaware, that Guidewire Insurance Suite and Guidewire ClaimCenter, two core Guidewire products, "have no substantial non-infringing use."

Accenture asked the court to order Guidewire to stop making and selling the software in the United States and award Accenture damages.

Guidewire, of San Mateo, California, was founded in 2002 and its 70 customers include Geico, AAA and Tokio Marine Nichido Fire. The company's chief executive, John Raguin, has said Guidewire grew more than 40 percent in the latest fiscal year.

Guidewire declined to comment.

Accenture could not be reached for comment.

Accenture LLP is the U.S. business of Accenture Plc (ACN.N: Quote, Profile, Research), which is incorporated in Ireland. Shares of Accenture were down 1.5 percent in late trade on the New York Stock Exchange.

The case is Accenture Global Services GmbH a Switzerland Corporation and Accenture LLP v Guidewire Software Inc, U.S. District Court, District of Delaware, No. 09-cv-00848. (Reporting by Tom Hals; additional reporting by David Lawsky; Editing by Steve Orlofsky)
