USPTO Declares Invalid Third of Three Critical Rambus Patents

slew writes "This is a followup to this earlier story about 2 of 3 of Rambus's 'critical' patents being invalidated. Apparently now it's a hat-trick." There's something that seems unsavory and wasteful about a business environment in which a company's stock value "fluctuates sharply on its successes and failures in patent litigation and licensing." The linked article offers a brief but decent summary of the way Rambus has profited over the years from these now-invalidated patents.

Any money back?

So do Nvidia, Hewlett-Packard , et al have any chance of recovering any money they paid to Rambus, or are they simply out the entire amount, or has no actual money traded hands yet?

Fraud

USPTO: "Yeah, we approved these totally bogus patents that resulted in billions of dollars of litigation and now we're affirming our own malfeasance. What's your problem?" The USPTO needs to be sued into the stone age for this fraud.
