ENSURE TECHNOLOGIES SUCCESSFULLY DEFENDS FUNDAMENTAL PATENT FOR XYLOC WIRELESS PC SECURITY

Ann Arbor, Mich., June 19, 2001— Ensure Technologies, the award-winning leader in intelligent digital information security solutions, today announced that it has successfully defended the right to market its XyLocÔ wireless PC security solution in a lawsuit brought by Superwave Ltd. against Kanematsu Communications Ltd. (KCS), Ensure's distribution partner in Japan.

Earlier this year, Superwave sued KCS, alleging that Ensure's XyLoc solution infringed on its Japanese patent. The Tokyo District Court determined that Ensure Technologies' XyLoc products do not infringe on the Superwave patent. The court ruled that KCS is free to market Ensure's XyLoc products in Japan. Furthermore, no royalty or damages were assessed by the court.

"Patent litigation can be long and resource-intensive, but it is imperative that technology companies take a firm stance to contest invalid patent infringement claims," said Dr. Thomas Xydis, co-founder and chief technologist of Ensure Technologies. "We are pleased that the Tokyo District Court concurred."

Ensure Technologies helps organizations protect their digital information by deploying wireless security solutions that deliver convenience and easy of use to end users. XyLoc is a patented computer security and personalization solution that prevents unauthorized access to confidential company data, and simultaneously makes access to network services and business applications more convenient for authorized employees. XyLoc enables the computer to know automatically and effortlessly who is requesting access to its resources, delivering a level of personalization and convenience previously unavailable in security solutions.

XyLoc's full-time access control technology protects confidential data when it is most vulnerable - after logon, when the authorized user - for whatever reason - steps away from the PC. Suited for professionals who need easy, yet secure, access to information "on the fly," XyLoc is proximity-activated and completely "hands-free," requiring no user interaction.

XyLoc has received RSA SecureID® and Keon® Ready certification from RSA Security, and Entrust-Ready™ Branding certification from Entrust Technologies. Ensure is an associate member of the Bluetooth™ Special Interest Group (SIG), a group working toward a wireless technology specification that provides links between mobile computers, mobile phones and other portable and handheld devices, and connectivity to the Internet. As more Bluetooth devices come to market, security will become essential to protect these devices from unauthorized access. Using XyLoc's patented technology, network managers can easily load and manage digital certificates on any Bluetooth PC, phone or PDA, which will add powerful security features to Bluetooth devices and appliances.
