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.

The suit is the latest in a series of legal spats between the two companies.
