LOS ALTOS, Calif.--(BUSINESS WIRE)--Rambus Inc. (Nasdaq:RMBS) today announced that the U.S. District Court for the Northern District of California has ordered Hynix Semiconductor (000660.KS) to secure the judgment amount of approximately $397 million through a combination of a bond and a lien on a Hynix property in South Korea for infringing Rambus patents. The bonded amount of $250M is required to be posted within 45 days of the order. The lien will only serve as security if a new appraisal of the Hynix property shows a fair market value of at least double the amount of the judgment not secured by the bond. If the appraisal is inadequate, Rambus may ask the Court to substitute other security. Final judgment in this matter was entered against Hynix on March 10, 2009 in the amount of approximately $134M for infringement through December 31, 2005 and approximately $215M for its infringement from January 1, 2006 through January 31, 2009. In addition, the Court awarded about $48M in pre-judgment interest to Rambus.
In addition, the Court ordered Hynix to pay compulsory license fees into escrow pending the outcome of the appeal Hynix filed in this matter. The Court ordered Hynix to pay Rambus royalties on net sales after January 31, 2009 and before April 18, 2010 of 1% for SDR SDRAM and 4.25% for DDR SDRAM memory devices. The latter rate applies to DDR, DDR2, DDR3, GDDR, gDDR2 and GDDR3 SDRAM devices, as well as DDR SGRAM devices. Damages and the compulsory license apply to U.S. infringements of the patent claims in suit.
