Based on this, it sounds like the ruling wasn't all that unfavorable to Rambus. Yes, the appeals court ruled that Rambus destroyed documents, but it also *reversed* a ruling throwing out one of their lawsuits, holding that the patent can't be ruled unenforceable without evidence that Rambus deliberately got rid of evidence that would have hurt its case, and so far neither defendant has even pointed out any reason why the shredded documents would have made a difference in the case. It sounds to me like the lawsuits are very much alive, while the market has reacted as if Rambus was thrown out of court and had the door slammed shut and padlocked.
I admit that I don't know a whole lot about this, I just bought some calls for a technical bounce due to an extremely oversold condition on what sounds to me like an overreaction, and this article supports that view. The Delaware lawsuit was given new life after previously being dismissed, and based on the ruling it doesn't seem likely that Rambus will wind up completely empty-handed. Does this really justify a 30% crash? If so, why??
