Rambus's patents were filed in 1990!
The JEDEC meetings were in the mid-90's!!!!
Jedec kept no meeting minutes and no membership rosters, apparently.
We don't even know the dates of the meetings, or if Rambus was even a member of JEDEC.
While various changes may have been made to some of the Rambus patent applications
while they were being approved (they were filed YEARS before the JEDEC meetings), we
have no way of knowing what the relationship was of those changes to the JEDEC meetings.
It is only speculation that Rambus incorporated items being discussed at JEDEC meetings
into the patents. And, even if this did happen (just for the sake of argument), it may not
have been material to the actual substance of the patent.
All that said, the JEDEC meetings NEVER produced a working open-standard SDRAM memory
ANYWAY. It remained for INTEL to develop an SDRAM standard that actually worked, and
this was a few years later still.
Further, SDRAM aside, DDR remains an entirely separate issue from SDRAM. Rambus has patents,
separate from the SDRAM patents, covering DDR that the memory makers are also trying to
invalidate. However, DDR was a MUCH later development for the memory makers other than
Rambus, and DDR was NOT discussed at the JEDEC meetings, while Rambus' patents covering
DDR were also filed from 1990 to 1992. So, even if the Jedec argument holds and the SDRAM
patents are invalidated, that won't, in and of itself, invalidate the DDR patents.
Finally, the courts presume that the patents are valid and the burden of proof is
on Micron, et. al., to PROVE -- in the legal sense -- that they are invalid.
