NEW YORK, Jan 20 (Reuters) - Rambus Inc. (RMBS.O: Quote, Profile, Research) , a designer of computer memory technology, on Thursday said a U.S. Federal court has ruled that South Korean chip maker Hynix Semiconductor Inc. (000660.KS: Quote, Profile, Research) infringed on certain Rambus patents for memory products.
Rambus shares jumped 27 percent before the bell.
The San Francisco-based company said it has received seven summary judgment rulings from the U.S. District Court of Northern California regarding patent infringement and validity issues in the Rambus patent case.
The court found that Hynix infringed 29 claims from four Rambus patents, Rambus said.
Rambus, which is seeking to collect billions of dollars in royalty payments from makers of dynamic random access memory (DRAM), said in a statement that Judge Ronald Whyte also granted one of the six summary judgment motions filed by Hynix.
Hynix filed suit against Rambus in August 2000 seeking to declare 11 Rambus patents invalid. The case has been divided into two parts, the first of which is set to be tried starting on March 21 in the U.S. District Court in San Jose, California.
The second phase of the case is scheduled to be tried in June and it will focus on various non-patent defenses and counterclaims asserted by Hynix, Rambus said.
Shares of Rambus climbed to $22.62, up $4.77 in active pre-open trade, up from Wednesday's close of $17.85. |
