Rambus Receives Federal Circuit Decision in Patent Reexamination

Although the Federal Circuit has affirmed the USPTO’s rejection of claim 18 of U.S. patent No. 6,034,918, the decision does not affect the PTO’s previous confirmation of the two other claims challenged in the reexamination

Rambus Inc. (Nasdaq:RMBS) announced August 16 that the United States Court of Appeals for the Federal Circuit has issued its decision in Rambus’s appeal of an ex parte reexamination of Rambus patent No. 6,034,918.

Although the Federal Circuit has affirmed the PTO’s rejection of claim 18, the decision does not affect the PTO’s previous confirmation of the two other claims challenged in the reexamination. These two claims were asserted by Rambus and in a jury trial before Judge Whyte in the Northern District of California found to be infringed by SK Hynix. Claim 18 was not asserted in that patent trial.

“While we respectfully disagree with the Federal Circuit decision, we are pleased that the PTO previously confirmed the two other claims challenged in the reexamination. These two claims were amongst the ten that a jury in California found valid and infringed by SK Hynix,” said Thomas Lavelle, senior vice president and general counsel at Rambus. “We are evaluating our options for the 918 decision and remain committed to protecting the technology developed by our talented team of engineers.”
