    Well they also made money from providing ram for N64s and PS3s. Didn't they get muscled out of the ram market?

    I don't have a problem with companies "patent trolling" if they legitametly have a case. It seems that Rambus was abusing the system though and the best thing that could happen would be for them to go away.

    They weren't muscled out they priced themselves out of the market. I remember when rambus was released and their ram was 2-3 times as expensive and anyone who wanted to make rambus ram had to pay huge royalties to them. Then came along DDR ram which was cheaper and faster and wallah a dead technology that uses obvious patents to troll for the rest of it existence.
  5. "The invalidation of these key patents is likely to affect the agreements made with many companies, including Nvidia and Broadcom."

    In all likelyhood, it will not, since the terms of the agreements are typically made such that the agreement remains in force regardless of whether the patent is later found to be invalid.

    ^^^ The judgement against Rambust's patents (ambush), doesn't affect technology associated with other patents deemed valid. What it does do, is affect any hopes that Rambust can strongarm companies into entering into further contracts based in large part from the threat of litigation....see the Rambust / Samsung "agreement", where Samsung was obliged to buy $200 million in Rambus stock -now "worth" a third of it's 2010 value.
    Also note that many licence agreements that Rambust have entered into, still need to be renewed- or not, periodically.
