The USPTO just validated 48 of 51 claims in patent number 6,697,295 (and the three claims that weren't validated related to delay lock loop and HJW and a jury has already addressed those).
On patent number 6,324,120, numerous claims were validated, but claim 33 being validated was huge. It was in the DDR case, the DDR2 case and in Micron's case. In the DDR case, it was granted Summary Judgment by HJW. This one claim being validated by the USPTO puts an end to any possibility that all of the Hynix 1 validity rulings ruling will be overturned. It also kills Samsung, because they can't even contest the validity for this one.
These rulings show the USPTO is not biased...and they are now validating key Rambus claims in the Action Closing Prosecution. Of course, in the initial phase of the reexams, they are still rejecting all claims and putting the burden of proof on Rambus. They just did that in two new reexams (108 and 109), but all this means is that Rambus has to address the issues the examiner has said raises a substantial new question of patentability. For example, on the 295 patent, the exmainer initially rejected all 51 claiums....and now 48 of the 51 are ruled valid.
IMHO, this is the first in a series of good news events for Rambus.
When the significance of what the USPTO sinks in....the stock should take off.
