SAN FRANCISCO (Reuters) - Rambus Inc. (RMBS.O: Quote, Profile, Research) , a designer of memory microchip technologies, said on Tuesday it had filed a patent infringement lawsuit against Hynix Semiconductor (000660.KS: Quote, Profile, Research) , Infineon Technologies (IFXGn.DE: Quote, Profile, Research) , Inotera Memories and Nanya Technology Corp.(2408.TW: Quote, Profile, Research) .

Shares of Rambus rose to $18.82 on Inet from a close of $18.31 on Nasdaq. The suit comes less than a week after Rambus said a federal court in a pretrial hearing had ruled that chip maker Hynix infringed on four patents.

Rambus said the Tuesday filing in the U.S. District Court for northern California charged that the defendants' DDR2 memory devices and GDDR2 and GDDR3 graphics memory devices infringe up to 18 of its patents.

"With analyst firms projecting a rapid transition this year from DDR to DDR2 and GDDR, and with strong evidence of infringement of our patents already in the public record, we have taken this step today, filing our first new patent case in the U.S. since August 2000," John Danforth, senior vice president and general counsel at Rambus, said in a statement.

"Our preference is to work with the semiconductor industry to provide value and resolve these issues through other means. But sometimes we -- like other patent holders -- must rely on the court system to be fairly compensated for our inventions."
