Is this because they were "submarine patents" or due to all the prior art?
However, the U.S. Patent and Trademark Office has initially ruled that Rambus may not have full claim to some of the patents involved in the current dispute with Nvidia. If that is finalized, it could put an end to any ITC actions. [ID:nN24320612]
There is SO much wrong with the post that started this thread.
First, so the PTO THINKS that SOME claims of SOME patents may not be valid. Well, Rambus has about 3 to 5 dozen claims per patent. They need exactly ONE. ***---ONE---***.
Second, the PTO actions themselves are not final. Normally the way that re-exams work is that they start by declaring almost everything invalid and making the patent holder argue his way back before they get to a "final" office action. Which, it turns out, STILL is not final.
Third, the PTO is simply not the final word any of these (even after the final-final action). After the PTO, there is a review by the BPAI, and after the BPAI, the case goes to the CAFC. This is a process that takes ..... well, about six to 8 YEARS. However, in this case, the appeals of the NVidia ITC case will hit the CAFC directly later this year. THIS YEAR. At which point, the PTO process will simply stop, because it is the CAFC that has the final word.
Someone mentioned that AMD's license expires this year ..... GOOD (for Rambus). Because AMD got their license before they acquired ATI, and has been getting a nearly free ride. When the license expires, they will have to sign a new license, and will be paying a more reasonable fee (e.g. more).
