9/3/2004 - Agilent Technologies Inc. (NYSE: A) has filed a motion with the U.S. District Court for the Northern District of California to add two additional patents in the pending lawsuit against PixArt Imaging Inc. for patent infringement. The motion alleges that PixArt infringes Agilent's additional U.S. Patent No. 5,686,720 and U.S. Patent No. 5,786,804 relating to optical mouse sensor technology.
PixArt earlier had brought a declaratory judgment action seeking a determination that Agilent's U.S. Patent No. 6,433,780 relating to optical mouse sensor technology is invalid and not infringed. In response, Agilent filed a suit for patent infringement in the U.S. District Court for the Northern District of California.
Agilent is seeking to stop PixArt from selling optical mouse sensors to companies manufacturing optical mice that are imported, distributed or sold in the United States. Agilent also is seeking damages from PixArt for its unauthorized use of Agilent's optical mouse sensor technology.
"Agilent is the pioneer in the development and commercialization of optical mouse sensor technology," said Young Sohn, president of Agilent's Semiconductor Products Group. "We have a significant and growing patent portfolio in the United States and other countries that covers a wide variety of technologies relevant to optical mouse sensors and optical mice. We will vigorously protect our significant investment in developing this breakthrough technology from anyone who would infringe on our intellectual property rights."
Agilent has shipped more than 300 million optical mouse sensors since the release of its first navigation sensor in 1999. Agilent supplies these sensors to all major optical mouse manufacturers worldwide. The technology works on virtually all surfaces by taking thousands of digital pictures per second, and is used in optical mice that range from inexpensive, entry-level models to high-precision versions. Since their introduction, optical mice powered by Agilent's optical sensing technology have established themselves as the standard in computer input devices.
