A patent provides intellectual property rights, which include the right to exclude others from making, using, or selling an invention.

Biography: Before he was a patent attorney, Mr. Fisher was an electrical engineer.
For 25 years, he practiced engineering in RF systems, semiconductors, and
computer hardware and software during employment by the Westinghouse
Electronic Systems Division. Since 1990, he has practiced law as a patent
attorney. He routinely prepares and prosecutes patent applications and
appeals. He also prepares product clearance opinions,
infringement and invalidity opinions when a client is threatened by a
patent owner or when preparing for license negotiations.

Engineering: On various RF projects, Mr. Fisher designed and tested
phased array antennas including stripline distributed feed systems and the
testing of the microwave magnetic properties of yttrium iron garnets used
in ferrite phase shifters. He has designed and tested “leaky pipe”
waveguide antennas, reflector antennas and simple dipole and patch
radiating structures. He has designed transmitter amplifiers using
transistors, traveling wave tubes and klystrons, and he has built and test
crystal protecting TR switches (diplexers). He has designed mixers,
amplifiers, oscillators and filters that operate from microwave frequency
to lower intermediate frequencies. He also designed infrared imaging
systems, image signal processors and image recognition systems. Using
such components, he has designed system modes for radars, radar warning
and surveillance receivers, jammers, secure anti-jam communication
transceivers and countermeasures for operation against tracking and early
warning radars, against command guided and semi-active radar guided
missiles and against radar homing and infrared homing missiles. Many of
these designs were prototypes for such systems as AWACS, F-16, AH-64, and
B-1B.

In semiconductor projects, Mr. Fisher designed hybrid computer circuits
implemented in thick and thin films on alumina substrates to interconnect
individual chips. In still other projects, he developed memory circuits
based on oxide-nitride insulating structures in FET gates where the thin
oxide (about 10 Angstroms) trapped electrons that were injected or removed
from sites between the oxide and nitride layers to alter thresholds.
Other semiconductor designs used CMOS technology to achieve custom made
microcircuits, and he also tested several semiconductor devices in nuclear
radiation environments.

He has designed digital pipeline processors for radar clutter cancelling
filters and later designed more generally programmable digital signal
processors for various uses. He has designed and programmed general
purpose computers for test equipment and for airborne fire control. He
has developed computer aided design (CAD) programs for checking properties
of integrated memory circuit designs such a distributed capacitance and
inductance. He has developed computer aided manufacture (CAM) programs
for drilling via holes in printed circuit boards, for controlling a light
pen to expose photo negatives for patterning copper clad PWBs, and for
controlling a wire wrap machine for making mother boards into which the
PWBs are plugged. He has programmed computer diagnostic tests. He has
developed design requirements and time budgets for designers of real time
missile fire control software.
