Xybernaut jumps on patent

Xybernaut Corp. (Nasdaq: XYBR), a maker of wearable computing devices, soared 11 percent Thursday after it said it has been issued a U.S. patent for what company believes is a breakthrough for mobile computing.

After four years of development and patent applications, Xybernaut said it won a patent for "transferable core" technology. Shares rose over 60 percent Wednesday, when the company first announced the patent.

The transferable core, which will be smaller than a PDA, or Personal Digital Assistant, contains the brains of a PC -- its processor, memory and storage and I/O circuitry -- everything but the power supply and display.

Mobile computing has been a hot sector recently, with the maker of popular PDA, Palm, making its public debut in an IPO Thursday.

Xybernaut's transferable core means that business users and consumers will not need separate devices, such as PDAs, desktop PCs, laptops, cell phones, and pagers. Xybernaut calls the development a breakthrough in mobile convergence, since it will allow users to easily insert and remove the "brains" of their computing or communications device from one device to another -- including its memory, processor, operating system and applications.

"Mobile convergence has been a hot buzzword in recent months, but this is the first time anyone has developed a way to bring everything together in one package,'' noted Edward G. Newman, president and CEO of Xybernaut.

Corresponding patents have been filed in 26 countries for U.S. patent (#6,029,183), the company said.

Xybernaut's other products include its patented wearable computer, called the Mobile Assistant IV, a full-function Pentium PC that runs Microsoft MS-DOS, Windows, and Windows NT, along with UNIX, Linux and other operating systems that run on the Intel x86 architecture.
