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 
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
