Commerce One Selling Intellectual Property Assets

Commerce One, Inc. (OTC: CMRCQ), a provider of solutions for automating and integrating business processes across networks of customers, suppliers, and partners, has announced that it is conducting an auction to sell its patents and patent applications relating to Web services.

On October 6, 2004, Commerce One, Inc. and Commerce One Operations, Inc., its wholly owned subsidiary, each filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code (the "Bankruptcy Code") in the United States Bankruptcy Court for the Northern District of California ("Bankruptcy Court"), Case No. 04-32821-DM-11.

Web services are programmatic interfaces that can seamlessly travel among diverse networks and diverse applications and languages. Web services provide a standard way to interoperate among diverse software applications that run on diverse platforms. According to Wintergreen Research, in 2003, the Web services market, excluding portals, accounted for $208 million in revenue and could have a compound average growth rate of as much as 52% from 2003 through 2008.

The Company believes it has developed an important patent portfolio for the emerging Web services market. This portfolio includes seven issued U.S. patents and 30 U.S. patent applications.

In connection with its Chapter 11 proceeding, Commerce One is conducting an auction to sell its existing business operations, and a separate auction to sell its Web services patents and applications. I|C|M|B Ocean Tomo, an intellectual capital merchant bank, has been retained by Commerce One, and approved by the US Bankruptcy Court for the Northern District of California, as its strategic advisor in connection with the auctions. The Company has previously announced that it has entered into an Asset Purchase Agreement to sell its SRM Division and certain of its other assets to an investment group composed of ComVest Investment Partners II LLC ("ComVest") and DCC Ventures, LLC ("DCC"), subject to competing bids at the bankruptcy auction. Under the bidding procedures, the Web services patents will be sold subject to license to the purchaser of the SRM division and other Commerce One business operations to enable that purchaser to continue operating those businesses.

Bids on the Web services patents and applications must be submitted in writing by December 2, 2004 and must provide for an all-cash purchase price of at least $1,000,000. Bids on the Company's business operations, including its SRM Division, also must be submitted by December 2, 2004 and provide for an all-cash purchase price of at least $4,300,000. Interested parties should contact John Amster from Ocean Tomo at jamster@oceantomo.com or (415) 946-2600 for more information about the bidding procedures.
