Rambus, a designer of high-speed memory chips, may not use 12 of its patents to demand royalties from Micron Technology, a federal judge ruled. Judge Sue L. Robinson of United States District Court in Wilmington, Del., said the patents were unenforceable because Rambus destroyed documents, and called Rambus’s conduct “obstructive at best, misleading at worst.” Rambus said it would appeal. The decision could affect Rambus’s ability to use the patents against other companies to obtain royalties, and might delay a trial set to begin Jan. 19, in which chip makers including Micron and Samsung Electronics are challenging 10 Rambus patents. Rambus fell $7.26, or 39 percent, to $11.24, its largest plunge since going public in 1997.
