ESI Announces Court Orders in Patent Litigation PR Newswire - October 05, 1998 09:36 Jump to first matched term PORTLAND, Ore., Oct. 5 /PRNewswire/ -- Electro Scientific Industries, Inc. (Nasdaq: ESIO) today announced that on September 30, 1998 the U.S. District Court for the Northern District of California issued a series of orders regarding ESI's lawsuit against General Scanning, Inc. (Nasdaq: GSCN) of Watertown, Massachusetts for patent infringement. The lawsuit (Electro Scientific Industries, Inc. v. General Scanning, Inc. No. C 96-4268 SBA) alleges General Scanning is infringing certain claims of ESI's patent 5,265,114 entitled "System and Method for Selectively Laser Processing a Target Structure of One or More Materials of a Multimaterial, Mutilayer Device" ("the '114 patent") and ESI's patent 5,473,624 entitled "Laser System and Method for Selectively Severing Links" ("the '624 patent"). The Court ruled as follows: The Court granted ESI's Motion for Summary Judgment of Literal Infringement by General Scanning. The Court granted ESI's Motion for Summary Judgment on the issue of no inequitable conduct by ESI in the prosecution of ESI's '624 patent. The Court denied General Scanning's Motion for Summary Judgment of Invalidity of the asserted claims of the two ESI patents ('114 and '624). ESI initiated litigation against General Scanning in December 1996. The lawsuit is still pending in the U.S. District Court for the Northern District of California. The patented technology is used in ESI's advanced laser repair systems that produce 64 and 256 megabit memory chips and semiconductors with embedded memory. The systems are enabling technology for the next generation of semiconductor yield improvement and are the most advanced laser repair systems available on the market. The systems feature patented laser system technology operating at a wavelength of 1.3 micron and offer semiconductor manufacturers a much wider process window and higher repair yields than systems using conventional, 1.047 micron laser technology. About ESI ESI, headquartered in Portland, Oregon, designs and manufactures sophisticated products used around the world in electronics manufacturing including: laser manufacturing systems for semiconductor yield improvement; production and test equipment for the manufacture of surface mount ceramic capacitors; laser trim systems for precise electrical tuning of circuits; precision laser and mechanical drilling systems for electronic interconnect; and machine vision systems.
