U.S. District Judge Robert Payne entered a permanent injunction that bars Rambus from asserting a series of patent claims against two classes of Infineon memory chips. The order follows earlier rulings that found Rambus guilty of fraud by not disclosing patents and patent applications to a standards body that set specifications that Infineon followed in designing its chips. The latest ruling extends legal protection to a relatively new category of memory chips known as double data-rate synchronous dynamic random-access memory chips, as well as an earlier type that was directly associated with specifications set in 1995. 1Court Postpones Chip-Patent Case Hynix Had Filed Against Rambus (Nov. 22) 2Court Sets Aside Part of Jury Verdict in Dispute Between Rambus, Infineon (Aug. 10) Gregory Arovas, an attorney for Infineon, termed the ruling a total victory for the company, which is based in Munich, Germany. John Danforth, general counsel for Rambus, of Los Altos, Calif., said the company was still studying the ruling. But he said it appears that the order "builds on mistakes" the court made before that Rambus is appealing. "It adds more mistakes that we will separately appeal," Mr. Danforth said. The ruling was disclosed after stock markets closed. Rambus shares fell 24 cents to $10.09 in 4 p.m. trading Monday on the Nasdaq Stock Market. Infineon Technologies' American depositary receipts rose $1.25 to $21.20 on the New York Stock Exchange. Rambus was found guilty in May of using fraudulent means to obtain patents for its DDR-SDRAM through a computer industry trade group. The U.S. District Court for the Eastern District of Virginia ordered it to pay $3.5 million to Infineon. The $3.5 million was later reduced to $350,000, but a ruling in early August upheld and earlier order to Rambus to pay $7.1 million to Infineon to cover attorney fees and expenses from the high-profile case.
