EDEN PRAIRIE, Minn.--November 5, 2001--NVE Corporation (OTCBB: NVEC) announced today that the U.S. Patent and Trademark Office has issued the company its twentieth U.S. patent, number 6,300,617. The new patent, entitled "Magnetic digital signal coupler having selected/reversal directions of magnetization," significantly strengthens the company's magnetic coupler intellectual property portfolio.

Couplers, also known as "isolators" because they electrically isolate as well as transmit data, are widely used in industrial and factory networks, instruments, and telecommunications. The new patent covers NVE's unique IsoLoop® design. The IsoLoop is a microscopic coil which creates a magnetic field. The field is sensed by an integrated Giant Magnetoresistor (GMR) array, transmitting digital data almost instantly. With data rates of 100 million bits per second, NVE's magnetic couplers are five times faster than any other semiconductor couplers. Detailed product data sheets are available at NVE's website, www.isoloop.com.

"This patent is a credit to our design team led by Dr. Jim Daughton, our founder and Chief Technology Officer, and the product team headed by John Myers," commented NVE President and Chief Executive Officer Daniel A. Baker, Ph.D. "The patent solidifies NVE's position as the leader in high-performance couplers."

NVE designs and manufactures magnetic sensor and coupler components which revolutionize data acquisition and transfer, and is a leading developer of magnetic memory technology.
