Innovation Inside: Patent Powerhouse: Xerox Boasts 101 Inventors with 50 or More Patents

ROCHESTER, N.Y.--(Business Wire)--Lalit K. Mestha's 50th U.S. utility patent, awarded just days
after his 50th birthday last month, is not only a milestone for him
but also a milestone for Xerox Corporation (NYSE: XRX). Mestha is the
101st Xerox inventor who has received 50 or more patents, showcasing a
culture of innovation that is both broad and deep. These inventors
have produced a wealth of innovations that distinguish Xerox products
and services and have helped create the modern office and the digital
printing industry.

Mestha is among hundreds of Xerox inventors with specialties
ranging from electrical engineering and polymer chemistry to solid
state physics and computer science. Their creativity has resulted in
more than 100 new products and services in the past three years and
the broadest portfolio of digital document systems and services in the
industry.

"Our selection last year as the recipient of the National Medal of
Technology, the highest technology honor in the United States,
officially recognized what I know: Xerox has some of the world's best
minds in our research and technology organizations. Their innovations
are creating and changing industries," said Sophie V. Vandebroek,
president of the Xerox Innovation Group and the company's chief
technology officer. "In every corner of our company, scientists and
engineers are creating the future today, and conceiving of products
and services that are delighting our customers."

Mestha, a principal scientist in the Xerox Innovation Group, was
awarded eight patents in 2007 and is one of eight Xerox inventors who
crossed the 50-patent threshold last year. His rich portfolio of
patents, grounded in the application of modern control theory and
centering on sensing and control of the printing process, was
instrumental in developing process controls in Xerox's flagship
iGen3(TM) Digital Production Press as well as high-speed spectral
sensing and consistent color innovations in other Xerox products.

His 50th U.S. patent, No. 7,307,720 "Method for corrected
spectrophotometer output for measurements on multiple substrates,"
addresses the question of how to measure color accurately on a variety
of substrates when using small, fast, and inexpensive in-line
spectrophotometers. The technology measures the color in prints to
help deliver consistent color print after print.

An innovation powerhouse for more than 50 years, Xerox has
developed deep expertise in marking, materials, electronics,
communications, software and services. Mestha joins other 50-plus
patent holders representing a variety of disciplines. Among them are:

-- Douglas Curry, a principal engineer at the Palo Alto Research
Center (PARC), holds 51 patents. He recently invented a
scanning microscope that identifies and locates cancer cells
in blood. In the late 80's he co-developed the world's first
quad-beam laser printer and the resulting hyperacuity printing
patents form the basis of today's multibeam laser printers.

-- Karen Moffat is a polymer chemist who works at the Xerox
Research Centre Canada. Moffat, who is an expert in the area
of toner materials design and synthesis, holds 52 patents,
many of which are related to toner materials including Xerox's
proprietary Emulsion Aggregation Toner. EA Toner is an
energy-saving dry ink that produces sharp, vivid images.

-- Markus Silvestri is a solid state physicist who also trained
in imaging and color science. Silvestri, who has 52 patents,
specializes in photoreceptors, the material on which the
latent image is formed prior to developing the printed image.
His inventions contribute to the goal of making copiers and
printers faster, with fewer print defects, and longer lasting
photoreceptors. He works in Xerox's photoreceptor development
area in Webster.

-- Bob Street, a physicist and senior research fellow at PARC,
has been awarded 53 patents. Street's current work focuses on
exploring high-volume printing technologies that could replace
techniques traditionally used to create thin-film transistors,
and using organic materials to create large-area transistor
and sensor arrays.

Xerox's investment in innovation generates a steady stream of
advanced technology. More than two-thirds of its equipment revenue is
from products and services launched in the past two years alone,
reflecting the company's ability to generate a strong return on its
R&D. Xerox holds more than 8,000 active patents and invests about 6
percent of its revenue in research, development and engineering
activities.

Xerox Corporation is the world's leading document management,
technology and services enterprise, providing the industry's broadest
portfolio of color and black-and-white document processing systems and
related supplies, as well as document management consulting and
outsourcing services. For more information, visit
