Federal Trade Commission Files Petition for Certiorari in the Supreme Court in Rambus Case

Los Altos, California, United States  - 11/24/2008   - Rambus Inc. (Nasdaq:RMBS), one of the world's premier technology licensing companies specializing in high-speed memory architectures, today announced that the Federal Trade Commission (FTC) has filed a petition for a writ of certiorari in the United States Supreme Court, seeking to overturn a decision by the U.S. Court of Appeals for the District of Columbia Circuit (CADC) in Rambus' favor. The CADC expressed "serious concerns" about the evidence on which the Commission relied for a number of its findings and held in particular that conduct by Rambus at a standards setting organization known as JEDEC did not injure competition.

"We are not surprised by the FTC's filing and we are hopeful that the Supreme Court will confirm the decision of the CADC," said Tom Lavelle, senior vice president and general counsel at Rambus. "We will file our response in the near future, and I note that the rulings of the FTC's administrative law judge, the CADC and a federal court jury in March of this year confirm that our position is the correct one."

In a unanimous decision in April of this year, the CADC determined the FTC failed to demonstrate that Rambus harmed competition. In March of this year, a Federal District Court jury found that Rambus did not engage in anticompetitive conduct and did not commit fraud, mislead or make misrepresentations to JEDEC.

The FTC brought antitrust charges against Rambus in 2002. A three-month trial was held in the spring of 2003 before Chief Administrative Law Judge Stephen McGuire, who issued his initial decision exonerating Rambus with over 1,600 findings of fact in its favor in early 2004. The FTC's own Complaint Counsel appealed the decision of the fact-finder to the full Commission, which reversed the ALJ and found Rambus liable for violating Section 2 of the Sherman Act.
