Broadband chip maker Broadcom has filed a patent infringement lawsuit in the U.S. District Court for the Eastern District of Texas against Intel, alleging that Intel chip sets have violated two of its graphics-related patents.
The suit, which was filed on Monday, alleges that three Intel chip set families for the Celeron and Pentium III processors -- the 810, 815 and 830 chip set families -- and Intel motherboards based on those chip sets infringe upon two patents held by Broadcom. The 810 and 815 chip set families are designed to be used in desktop PCs running the Pentium III and Celeron processors while the 830 is designed to be used with the mobile versions of these processors.
These three chip set families allegedly violate two graphics-related patents owned by Broadcom: U.S. Patent No. 6,189,064 B1, entitled "Graphics Display System with Unified Memory Architecture", issued on Feb. 13, 2001, and U.S. Patent No. 5,963,210, entitled "Graphics Processor, System and Method for Generating Screen Pixels in Raster Order Utilizing a Single Interpolator," issued on Oct. 5, 1999.
The suit asks that the court grant an injunction to stop the shipment of Intel products that violate these patents and seeks unspecified monetary damages.
Intel officials could not immediately be reached for comment.
This is not the first time that Intel and Broadcom have locked horns over patent infringement. In July, an administrative law judge for the U.S. International Trade Commission ruled that networking chips made by Broadcom infringed on two patents held by Intel.
