MatrixOne Granted Patent for Semiconductor IP Management; Comprehensive Patent Enables Collaborative Development and Component Reuse in Advanced Semiconductor Design.

GRENOBLE, France & WESTFORD, Mass. -- MatrixOne, Inc. (NASDAQ: MONE), a leading provider of collaborative product lifecycle management (PLM) solutions for the value chain(TM), today announced that the United States Patent and Trademark Office has awarded the company a patent for a system for managing reusable components, commonly referred to as IP (Intellectual Property) or virtual components in the electronics industry. The patent defines a comprehensive software application that provides a secure, high performance distributed library for cataloging, distributing, tracking, reporting and managing IP. This enables effective design reuse and the use of commercial components to meet the needs of increasing design complexity and faster time-to-market in advanced semiconductor design.

The new MatrixOne patent defines an innovative system that includes a master IP database and an IP Catalog. In addition, the patent defines:

--how this system can be securely deployed and accessed across both private and public networks;

--capabilities for IP Registration that will enable IP to be catalogued and evaluated according to defined reuse standards;

--the IP Selection capabilities that enable designers to locate IP that meets their needs and populate the work area within their EDA design environment;

--the IP Modification capabilities necessary to report, track and resolve errors or issues found in IP, and;

--the processes and capabilities that are used to manage the IP catalog, release and version the IP database and administer secure access.

"This comprehensive patent demonstrates our commitment to helping create the innovations that can solve the increasing complex product development problems faced by the global electronics industry," said John Fleming, senior vice president and general manager of MatrixOne's Electronic Business Unit. "Our semiconductor customers include leading large IDMs, fabless companies, IP design houses, fabs and foundries. They are all looking for innovative ways to compress development cycles, improve quality and lower costs. This patent, and the commercial solutions we have developed based on it, are enabling them to achieve these results."

MatrixOne has developed several commercial solutions for the semiconductor industry based on this patent, including MatrixOne's Synchronicity(R) Publisher Suite with IP Gear(TM). Several MatrixOne customers, including some of the world's leading semiconductor companies, use IP Gear to implement effective design reuse programs that meet the demands caused by ever-shortening cycles and increasing chip complexity.
