Major Taiwanese Semiconductor Manufacturer Licenses MOSAID Patent Portfolio

OTTAWA, Ontario – October 20, 2005 – MOSAID Technologies Incorporated (TSX:MSD) today announced that it has signed a five-year term, worldwide, non-exclusive, royalty bearing patent licensing agreement with a major Taiwanese semiconductor company.   The terms of the Agreement also call for a series of fixed payments to cover product sales prior to the date of the agreement. 

“We are very pleased and excited to add another one of the world’s largest DRAM manufacturers to the list of companies that have licensed MOSAID’s patent portfolio,” said Jim Skippen, Senior Vice President of Patent Licensing and General Counsel for MOSAID Technologies. “This is our fifth limited term license agreement. The limited term license model is important because it yields a revenue stream during the entire term of the license while offering an opportunity for its renewal at the conclusion of the term.”

“MOSAID is committed to ensuring the long term success of its patent licensing program,” added Skippen.  “In addition to our licensing model which has the potential for renewals at the expiration of a fixed term, we are also employing a number of strategies to enhance our current patent portfolio.  These strategies include analysis of our existing portfolio for new licensing opportunities, particularly with respect to our networking patents; active registration of patents resulting from the various R&D activities underway at MOSAID; and the purchase of key technologies and patents to expand the breadth of our licensing program.”

To date, MOSAID has signed patent licensing agreements with many leading DRAM and semiconductor manufacturers including Fujitsu, NEC, Toshiba, Hitachi, Mitsubishi Electric, Oki Electric, Matsushita, Winbond Electronics, Sony Corporation, Royal Philips Electronics, Samsung Electronics and Hynix Semiconductor.

MOSAID’s ability to broaden its licensing opportunity is supported by its current portfolio of 566 patents issued and pending. There are currently a total of 13 semiconductor companies on notice for patent infringement and MOSAID is engaged in licensing discussions with several of these companies.
