NVE Notified
of Two Patent Grants
Patent grants expected today for Superparamagnetic Devices
and Two-Axis Magnetic Field Sensor
EDEN PRAIRIE, Minn.--May 30, 2006--NVE Corporation (Nasdaq: NVEC)
said that it has been notified by the U.S. Patent and Trademark
Office (USPTO) that two patents are expected to be granted today.
The patents are titled "Two-Axis Magnetic Field Sensor"
and "Superparamagnetic Devices."
The Two-Axis Magnetic Field Sensor is patent number 7,054,114,
and is the grant of a patent under the application published by
the USPTO as number 2004-0137275. The invention is for a spintronic
device that can detect the magnitude and orientation of magnetic
fields. Applications for such devices might include Magnetoresitive
Random Access Memory (MRAM), or military, industrial, and medical
sensors.
The Superparamagnetic Devices patent is number 7,054,118 and is
the first patent granted from the application published by the USPTO
under number 2004-0023065. Other patents are possible based on this
application, although there can be no assurance if or when additional
patents will be granted.
Superparamagnetism is the magnetic state of a material between
highly ordered parallel spins (ferromagnetism) and randomly ordered
spins (paramagnetism). The superparamagnetic effect occurs in ferromagnetic
particles smaller than a critical value or at temperatures higher
than a critical temperature. In conventional storage systems such
as disk drives, superparamagnetism can be undesirable because it
limits storage density. The NVE invention utilizes the superparamagnetic
effect to improve the accuracy of spintronic sensors where a small
sensed field is sufficient to order the spins in a superparamagnetic
material. More accurate sensors would be useful in a number of applications
including military, medical, and biosensor.
The grants will bring NVE's U.S. patent total to 38. The company
has more than 100 patents worldwide issued, pending, or licensed
from others. Links to the new patents and NVE's other U.S. patents
can be found at the "About NVE" section of the company's Website
(www.nve.com).
NVE is a leader in the practical commercialization of spintronics,
a nanotechnology that many experts believe represents the next generation
of microelectronics. NVE licenses its MRAM intellectual property
and sells spintronic products, including sensors and couplers, to
revolutionize data sensing and transmission.
