The appeals court, however, found the FTC "failed to sustain its allegation of monopolization" and raised questions about whether there's enough evidence to support the FTC's claim that Rambus engaged in deceptive behavior at all in the standards-setting process. The court ruled that even if Rambus did deceive the engineering council, it did not harm competition in a monopolistic way, undercutting the FTC's argument that Rambus should be punished for violating antitrust laws. Tuesday's ruling follows another big legal victory for Rambus last month, when a jury in U.S. District Court in San Jose found in Rambus' favor in a related case. The jury found that Rambus didn't engage in monopolistic behavior, rejecting claims made by chip makers Micron Technology Inc., Hynix Semiconductor Inc. and Nanya Technology Corp. in a lawsuit originally filed in 2000. Micron said it planned to appeal the jury's finding.
