Rambus Receives Summary Judgment Rulings Finding Patent Infringement in Hynix Case
LOS ALTOS, Calif., January 20, 2005 - Rambus Inc. (Nasdaq:RMBS), a leading developer of chip interface products and services, today announced it has received seven summary judgment rulings from the United States District Court of Northern California regarding patent infringement and validity issues in the Rambus patent case involving Hynix Semiconductor.
In the Hynix case, Rambus has asserted that 59 claims from 15 patents are infringed by memory products manufactured and/or sold by Hynix. Each of these 59 claims was at issue in one or more of the seven summary judgment motions filed by the parties and decided this month by the Court.
"This summary judgment of infringement is great news and a major step forward toward our goal of being fairly compensated for our innovations," said John Danforth, senior vice president and general counsel at Rambus. "We look forward to trial, which is currently set for March."
Of the six summary judgment motions filed by Hynix, Judge Ronald Whyte granted one, resulting in nine claims in four patents containing the term "second external clock signal" being removed from the case. This reduced the number of claims in the case from 59 to 50. Hynix's arguments for summary judgment regarding validity and infringement challenging the remaining 50 claims were rejected by the Court.
Regarding Rambus's summary judgment of infringement motion, Judge Whyte made two sets of rulings. First, the Judge found there was a fact issue to be tried regarding the claim limitation ?read request." That limitation appears in 11 of the 40 claims raised by Rambus in its motion. The Court denied Rambus's motion for summary judgment on those 11 claims, and the issue of infringement with respect to these claims could go to trial.
Secondly, the Court entered summary judgment of infringement in Rambus's favor, finding that Hynix infringes 29 claims from four asserted Rambus patents. Those 29 claims are among the 50 Rambus claims that survived Hynix's summary judgment motions on non-infringement and validity.
The first phase of the trial is scheduled to begin on March 21, 2005. It will focus on remaining patent infringement and validity issues, and on Hynix's spoliation claim. 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.
When available from the public docket of the Court, these summary judgment rulings will be found on Rambus's website at www.rambus.com/inv (under Litigation Update section). These rulings issued in the form of a series of rulings beginning on January 3, 2005, five of which were made public in the same week as written. As to the two remaining rulings, one was subject to January 4 and 5, 2005 correspondence among the parties and a Clarified and Corrected Order issued yesterday.
