Business Wire, Feb 21, 2007

Magma Maintains Synopsys Products - Including Astro, Design Compiler, IC Compiler, Physical Compiler and PrimeTime - Infringe Magma Patents

SANTA CLARA, Calif. -- Magma[R] Design Automation Inc. (Nasdaq:LAVA) today announced it entered into a joint stipulation with Synopsys Inc. (Nasdaq:SNPS) which focuses the scope of their Delaware patent lawsuit but leaves in place Magma's assertions that its patents are being infringed by key Synopsys products, including Astro, Design Compiler, IC Compiler, Physical Compiler and PrimeTime.

The companies' joint stipulation, entered in the U.S. District Court for the District of Delaware, leaves unaffected Magma's assertion that these and other Synopsys products infringe four Magma patents: U.S. Patents 6,505,328, 6,519,745, 6,854,093 and 6,857,116. Also remaining at issue is Synopsys' assertion that Magma infringes one Synopsys patent, U.S. Patent 6,192,508.

The companies jointly stipulated to: Synopsys withdrawing infringement claims against Magma with regard to two of the three Synopsys patents at issue; Magma withdrawing infringement claims against Synopsys with regard to one Magma patent at issue; and Magma withdrawing claims of antitrust violation by Synopsys. The joint stipulation is subject to court approval.
