FAIRFAX, Va.--(BUSINESS WIRE)--April 23, 2002

Xybernaut(R) Corporation (Nasdaq:XYBR), today announced that in the first quarter of 2002 seven patents have been issued to the Company for mobile/ wearable computing and related technologies in the United States, the Republic of China and Hong Kong.

These U.S. and Asian patents recognize the specific features that define a wearable computer such as removable/transferable core components; docking stations and connector ports and PC Card and network interface connectivity. Stakeholder value continues to be enhanced as the company protects its most valuable assets on an international basis.

In the U.S., the Patent and Trademark Office (PTO) issued two Utility Patents and two Design Patents. Utility Patent 6,359,777 relates to a removable component structure for a mobile/wearable computer and Utility Patent 6,351,388 relates to a mobile/wearable computer with PC housing for PC card and network interface.

The Design Patents relate to a docking station for a portable computer and a connector port for a portable computer.

In the Republic of China, Xybernaut received grant 142992 (Personal Communicator) and grant 142471(Core Computer System).

In Hong Kong, the patent grant extends coverage of Xybernaut's original, "Hands Free User Supported Portable Computer," patent for mobile/wearable computers. Similarly, in 2001 Xybernaut announced recognition of various patents in nine European countries.

Recognition of the company's patents in countries beyond North America is an important aspect of Xybernaut's goal to bring wearable computing and related technologies to international markets. These most recent grants in the Republic of China demonstrate considerable momentum and success.

Xybernaut's original wearable computer patent is now recognized and protected in Australia, Canada, nine countries in Europe, Hong Kong, Japan, South Korea, the Republic of China and the United States. As such, stakeholder value continues to be enhanced as the company protects its most valuable assets on an international basis.
