Closing Arguments Heard in Rambus Trial

Rambus Inc. engaged in a “pattern of deceptive conduct” against the semiconductor industry to collect billions of dollars a year from computer makers, a U.S. government lawyer said at an antitrust trial. Rambus argued that an appeals court had rejected the fraud allegations in a separate suit.

The two sides presented closing arguments in the government’s case against the high-speed computer memory chip designer. Rambus attended meetings to set standards for chips while pursuing patents to earn royalties on them, said M. Sean Royall, the Federal Trade Commission’s deputy director of competition.

Los Altos, Calif.-based Rambus maintains it did nothing wrong and revealed everything it was required to disclose.

Rambus shares fell 69 cents to $26.77 on Nasdaq.
