angry tapir writes "A US appeals court has ruled on two patent lawsuits that pit Rambus against two competing DRAM makers, sending both cases back to district courts for reconsideration. The US Court of Appeals for the Federal Circuit vacated a lower court ruling requiring Hynix Semiconductor to pay Rambus damages and fees totaling US$397 million for the use of its patents in DRAM chips." Here's the issued opinion (PDF) in Hynix v. Rambus. The opinion in the other case (PDF), pitting Rambus against Micron, contains this juicy snippet: "On August 26, 1999, Rambus held the 'shredding party' it had planned as part of its third-quarter intellectual property litigation readiness goals. Rambus destroyed between 9,000 and 18,000 pounds of documents in 300 boxes."
