FAQ,
Rambus has sued just about all the memory makes for royalies on SDRAM and SDDRAM. There was a whole lot of evidence that came out that showed that Rambus played fast and loose with the JEDEC (SP?) standards body to get them to approve the SDRAM standard while Rambus was secretly patenting a lot of the ideas that were brought up in the meetings. Of course, that is against the JEDECs rules and probably illegal as well. Either way, the judge in the Infinion case just through out all the charges in the law suit that Rambus brought against Infinion. It is very good to see it go down in flames.
Personally, I really do think that if someone invents something and get it patented, they should be able to collect royalties from others who use that technology. But what Rambus did is a whole lot closer to "protection" racket than legitimate patents. Of course, software patents need to go into the trash all together! Let them use copyright law.
