Guidewire Software Refutes Latest Accenture Allegations.

SAN MATEO, Calif. -- Guidewire Software([R]), a leading provider of flexible core systems to property/casualty insurers, today issued a strong rebuttal of patent infringement allegations made by Accenture. Accenture made similar allegations against Guidewire in December 2007.

"Accenture is using the legal system to fight a battle they are losing in the marketplace. These allegations are a competitive tactic designed to disrupt our business. I am pleased to report they are failing in this attempt: since Accenture first made allegations against Guidewire, we have signed more than twenty-five new customers. Our customers and the industry know Guidewire's reputation for integrity and fair competition," said John Raguin, chief executive officer, Guidewire Software. "We believe Accenture's patents are invalid and that, in any event, our software does not infringe them. The patents appear to describe features of insurance claims management software that have been well known in the industry for many years, and that were certainly well known when the patents were filed."

Raguin continued, "We're pleased that the U.S. PTO has issued a preliminary ruling rejecting the claims in Accenture's '284 patent, the subject of Accenture's previous lawsuit against us and we have now asked the U.S. PTO to re-examine the validity of the '240 patent, which is the subject of Accenture's latest allegations."

Guidewire continues to be recognized as the market leader for modern claims systems in the P&C industry and has received numerous industry accolades, including:

* Ranked #1 P&C provider of Point Solutions and #1 Provider of Integrated Systems in the Insurance Networking News and Celent 2009 "Vanguards in Insurance Practices" survey;

* Attained a rating of "Strong Positive", the highest possible rating in Gartner's report titled "MarketScope: North American Property and Casualty Insurance Claims Administration Systems" for the years 2009, 2008, and 2007 respectively;

* Named top P&C 'Up and Coming Technology Firm' in the TechDecisions and Financial Insights 2009 "Insurer's Choice" survey; and

* Received highest marks in Celent's "U.S. Property/Casualty Market Claims Systems Vendors 2008" report.
