Rambus, Inc. Faces Stock Fraud Lawsuit, Berman DeValerio Pease Tabacco

Burt & Pucillo Says

Investors are pursuing a securities class action against Rambus, Inc. (Nasdaq: RMBS), accusing the chip designer of deceiving investors about important patents, the law firm of Berman DeValerio Pease Tabacco Burt & Pucillo said today.

The lawsuit was filed September 7, 2001 in the U.S. District Court for the Northern District of California as case number C-01-3403 MEJ and is pending before Judge Maria Elena James. It seeks damages for violations of federal securities laws on behalf of all investors who bought Rambus stock between January 18, 2000 and May 9, 2001 (the "Class Period").

Berman DeValerio has represented investors in class actions for nearly two decades. To review the complaint and learn more about becoming a lead plaintiff, please visit our Website at www.bermanesq.com.

The class action accuses Los Altos-based Rambus and three top executives with making false and misleading statements about the company's ownership of valuable patents for SDRAM computer memory technology. The company derives the majority of its revenues by charging royalty and license fees to chipmakers on patents it holds.

The truth about Rambus emerged after the company sued Infineon AG ("Infineon") for patent infringement. On March 15, 2001, the U.S. District Court judge trying the case ruled that Rambus had too broadly construed the parameters of its patents on SDRAM technology. In a subsequent trial, a jury found that Rambus had secured its SDRAM patents through fraud.

Throughout the Class Period, during which Rambus' stock reached a high of over $117 per share, Rambus falsely held itself out as the rightful owner of valuable patents on SDRAM technology that it would vigorously protect through litigation. It repeatedly touted its growing stream of revenues from SDRAM patent royalties, without disclosing that such revenues were unlikely to recur once its fraud in obtaining the patents had been exposed. It also failed to disclose that it would be unlikely to adequately enforce those patents given Infineon's courtroom defenses.
