Patent Infringement Business Editors NEW YORK--(BUSINESS WIRE)--Oct. 17, 2001-- Litigation Asserts Infringement by IC's and Computer Motherboards for the Philips-Patented Inter-Integrated Circuit Bus (I2C Bus) U.S. Philips Corporation, the subsidiary of Royal Philips Electronics of the Netherlands that has responsibility for licensing intellectual property, announced today that it has filed suits in the U.S. District Court in New York against eight companies for infringing and inducing others to infringe Philips' U.S. Patent Number 4,689,740. This patent is directed to devices and methods used with the Inter-Integrated Circuit Bus ("I2C Bus"). The companies are Atmel Corporation, San Jose, CA; LSI Logic Corporation, Milpitas, CA; Maxim Integrated Products, Inc., Sunnyvale, CA; Semtech Corporation, Newbury Park, CA; Abit Computer Corporation, Taipei Hsien, Taiwan; Asutek Computer, Inc., Taipei, Taiwan and Micro-star International Co., Ltd., Taipei Hsien, Taiwan. The suits also name Dallas Semiconductor Corporation, Dallas, TX, a subsidiary of Maxim Integrated Products, Inc., and various American subsidiaries of the Taiwanese companies. Damages were not specified. Trial dates have not been set. The suits allege that the five U.S. company defendants manufacture infringing integrated circuits. The three Taiwanese companies are accused of importing infringing integrated circuits, motherboards and/or computers into the United States. I2C Bus Facilitates Interconnectivity The I2C Bus is a serial data path that is widely used to interconnect semiconductor chips on circuit boards in personal computers, television sets, audio components, telephones and other consumer electronics equipment. Philips Electronics, together with more than fifty other companies licensed to use the patent, manufacture and sell circuits with interfaces that enable the transmission and receipt of digital signals on an I2C Bus. The I2C Bus was originally developed in the 1970's to simplify and reduce the cost of interconnections within Philips products and its use has become an informal standard in the consumer electronics industry. The patented methods and device functions have also been incorporated into later standards. Philips has a long-standing program to license its I2C patents to semiconductor manufacturers on fair and reasonable terms, but the defendant semiconductor manufacturers have refused to participate in the program. Initial Infringement Suits Filed Last Year On October 2, 2000, Philips sued a first group of six semiconductor manufacturers for infringing the I2C patent. Two of the original defendants, Cirrus Logic, Inc. and Linear Technology Corp., have since settled and concluded license agreements with Philips. The October 2000 litigation continues with the four remaining defendants: Analog Devices, Inc., Norwood, MA; Cypress Semiconductor Corp., San Jose, CA; Fairchild Semiconductor Corp,. South Portland, ME; and Standard Microsystems Corp., Hauppauge, NY. A trial is expected in mid-2002.
