MOUNTAIN VIEW, Calif. -- MIPS Technologies filed a lawsuit here late Thursday against Lexra for infringement of two United States patents covering fundamental aspects of the MIPS RISC architecture.
The suit was filed by MIPS Technologies in the United States District Court for the Northern District of California.
"MIPS Technologies is a world leader in the design and marketing of reduced instruction set computing RISC microprocessor technology," said John Bourgoin, MIPS Technologies' president and CEO. "Although MIPS Technologies and Lexra have discussed a potential license, no agreement has been reached, and MIPS Technologies had little choice but to file this suit to protect its valuable patent rights.
Waltham, Mass.-based Lexra could not be reached for comment.
In its complaint, MIPS Technologies says Lexra's LX 4080, LX 4080P, LX 4180, LX 4280, and LX 5280 all infringe one of its patents, while the LX 4280 and LX 5280 infringe a second patent.
MIPS Technologies also identified nine additional U.S. patents it said it believes Lexra may be infringing, but no formal claims have yet been made regarding those patents. MIPS Technologies is seeking damages for past infringement, and a permanent injunction precluding Lexra from any further marketing or sales of the products named in the suit.
"We simply will not sit by and allow our valuable intellectual-property rights to be infringed," said Bourgoin.
