June 13, 2005 - An investor in shares of Magma Design Automation Inc (NASDAQ: LAVA) filed a lawsuit in the U.S. District Court for the Northern District of California against Magma Design Automation Inc over alleged violations of Federal Securities Laws in connection with certain allegedly false and misleading statements made between October 23, 2002 through April 12, 2005.

The original complaint alleges that Magma Design Automation Inc and certain of its officers and directors violated Federal Securities Laws. Specifically, defendants failed to disclose that Magma Design Automation Inc faced the serious risk of infringing on intellectual property rights of competitor Synopsys because inventions that were critical to Magma Design Automation Inc's business, and which were patented by Magma Design Automation Inc, were designed by Magma Design Automation Inc's chief scientist while employed by Synopsys. Defendants aggressively denounced the allegations, characterizing them as completely baseless. While Magma Design Automation Inc's stock price was artificially inflated, insiders sold 4,436,163 shares of common stock reaping gross proceeds of $82,385,174.

The complaint further alleges that on or around April 13, 2005, the market learned that Magma Design Automation Inc's Chief Scientist admitted, in a sworn declaration filed in the Synopsys infringement action, that inventions covered by two of Magma Design Automation Inc's patents were conceived by him while he was employed by Synopsys and that his supervisor at Magma Design Automation Inc, and likely others, knew that the inventions covered by the patents were conceived by him at Synopsis and were encompassed by an agreement with Synopsis granting Synopsis the rights to those inventions. On this news, Magma Design Automation Inc's stock (NASDAQ: LAVA) plummeted 40.7%, from $9.42 per share on April 12, 2005 to $5.58 per share on April 13, 2005.

Also included are all those who acquired Magma's shares through its acquisitions of Majave, Random Logic, Aplus Design or Silicon Metrics.
