Company Portfolio Signals 70-Year Legacy of R&D Strength ROCHESTER, N.Y.--Oct. 14, 2002--Reflecting the power of thousands of scientists' ideas, experiments and "a-ha!" moments, Xerox Corporation has reached a milestone of earning more than 15,000 U.S. patents, underscoring its leadership and legacy as one of the world's top technology innovators. The 15,000th utility patent, earned by Xerox scientists Angelo Barbetta and Robert Bayley, was awarded on Sept. 17, nearly 70 years after Xerox's predecessor - Haloid Co. - received its first U.S. utility patent on Sept. 26, 1933. Utility patents - the most common type - cover any new and useful processes, machines, devices, manufactured items, or chemical compositions of matter. Over the years, Xerox has secured about 45,400 patents in total, worldwide. Combined with Xerox's joint-venture partner in Japan, Fuji Xerox, the Xerox group total stands at more than 18,000 U.S. patents and 55,300 patents worldwide. "Innovation manifests itself in many forms, but clearly patent generation is a significant measure of research and intellectual property strength. This milestone is a credit to Xerox researchers, scientists and engineers today and the prolific generations who preceded them," said Herve J. Gallaire, Xerox's chief technology officer and president of the Xerox Innovation Group. "Their innovation helps ensure Xerox consistently leads the way in products, solutions and services that improve work and business for our customers." It was Xerox researchers who established the science and technology of xerography and created the foundation for the digital workplace. They also have invented several "firsts" over the years, including the plain-paper copier, the plain-paper fax machine (known as "long-distance xerography"), full- and highlight-color xerographic imaging, the first laser printer, on-demand printing technology including MICR check printing, solid-state lasers, an array of document management software, and much more. However, Xerox scientists also have found that sometimes the best way to innovate is to re-examine and then improve what has proved successful before. For example, the company's 15,000th patent - U.S. Patent No. 6,451,495 - covers a novel composition of "toner and developer with charge-enhancing additives." Conventional toner is a mix of plastic resin, colorant and chemical additives that control the electric charges of the toner. Additives that enhance or balance the charges are important to ensuring that a sharp, clear image is produced during the xerographic process - because xerography relies on electrical charges to transfer an image to paper. The new toner composition is the latest addition to Xerox's extensive portfolio of formulations for toners. Barbetta and Bayley work in Xerox's Supplies Delivery Unit, in Webster, N.Y., which designs, develops and produces imaging materials and components used in Xerox printers, digital presses and copiers. Barbetta, vice president of toner development and manufacturing in SDU, joined Xerox in 1973. He graduated from LeMoyne College (Syracuse, N.Y.) with a bachelor of science degree in chemistry, received a doctorate in physical chemistry from Purdue University, and also received an MBA from the University of Rochester. Barbetta is a member of the American Chemical Society. The 15,000th patent is also his 20th at Xerox, all within the toner/developer materials area. Bayley, a senior technical specialist and synthetic polymer chemist in SDU, joined Xerox in 1972. He received his bachelor of science degree in chemistry from the Rochester Institute of Technology. His 31 patents earned at Xerox are primarily in polymer technologies, but several cover charge-enhancing additives. "Xerox is the world leader in xerographic materials and processes, which we leverage to add value for our customers. Patents such as this are a significant part of that leadership," said John R. Laing, senior vice president, Supplies Delivery Unit. "Our aim is not to push technology but to look at problems and solve them with technology." Xerox Corporation, one of the world's top technology innovators, spent about $1 billion on research and development in 2001. Together with Fuji Xerox, the total R&D commitment was about $1.5 billion.Xerox operates research and technology centers in the United States, Canada and Europe that conduct work in color science, computing, digital imaging, work practices, novel materials, and other disciplines related to Xerox's expertise in printing and document management. Xerox consistently builds its inventions into business by embedding them in superior products and solutions, using them as the foundation of new businesses, or licensing or selling them to other entities.
