ROCHESTER, N.Y., Jan. 14, 2008 -- Xerox Corporation (NYSE: XRX) was granted 584* U.S. utility patents in 2007, adding to its extensive intellectual property portfolio. Many of the patents are already fueling new technologies embedded in products and services Xerox brought to market within the last year, while others provide the foundation for the next generation of products, services and software. The total includes patents awarded to the Palo Alto Research Center, a wholly owned subsidiary of Xerox Corporation.

Spanning specialties ranging from nanotechnology, controls and materials synthesis to software systems and smart document technologies for services, the patent total represents an increase of 31 percent over patents awarded to Xerox in 2005. At that time, Xerox announced a goal of boosting the number of patents it was awarded by one third in three years. With a year to go, the company is well on its way to delivering on that goal.

Xerox's joint venture partner in Japan, Fuji Xerox Co. Ltd., was awarded 317 U.S. utility patents, bringing the total for the Xerox Group to 901. Together, Xerox and Fuji Xerox invest about $1.5 billion annually in research and development.

"Inventions are not innovations until they delight our customers. Over the past years, Xerox has focused its extensive RD&E efforts to deliver breakthrough innovations, which have been embedded in products and services generating billions of dollars in recurring revenue for the company," said Sophie Vandebroek, Xerox chief technology officer and president of the Xerox Innovation Group. "Last year Xerox brought 39 new products and services to market. As importantly, our inventors have laid the groundwork for many more, some of which will expand our reach into new industries."

Among the patents granted in 2007 that may appear in future Xerox products and services:
