Court Rules in Favor of ARM in Patent Infringement Suit

CAMBRIDGE, UK — Oct. 1, 2003 – ARM [(LSE: ARM); (Nasdaq: ARMHY)], the industry's leading provider of 16/32-bit embedded RISC microprocessor solutions, today announced details of the company's patent infringement litigation with Nazomi Communications, Inc., over ARM's intellectual property incorporating the current commercial design of its Jazelle® Java accelerator technology.

Yesterday, Judge Fogel in the United States District Court for the Northern District of California issued his ruling on ARM's early summary judgement motion in Nazomi's patent infringement suit against ARM. Judge Fogel's decision favors ARM and grants ARM's motion for partial summary judgment by ruling that products using the current commercial design of ARM's Jazelle technology do not infringe on Nazomi's U.S. Patent number 6,332,215. Only the part of the lawsuit that relates to earlier, discontinued ARM prototypes will, for now, proceed. This decision means that ARM may continue to provide leading designs of microprocessor solutions incorporating its Jazelle Java accelerator technology to the market.
