  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.
