The basis of the case, according to commissioners, is that Rambus allegedly persuaded the JEDEC standards group to take up technology that it was filing patents for without telling it.
According to the director of the FTC's bureau of competition, this damaged several technology market.
The case centres around patents that Rambus claims it owns relating to SDRAM and DDR technology.
In a much reported case last year, Rambus was convicted of fraud - a case that it is appealing.
During that case, it emerged that while attending meetings of the JEDEC memory standards committee, Rambus was filing patents for technology while it was a member of the committee.
Subsequently Rambus left JEDEC, but is still pursuing court cases against memory makers which it claims should license its technology.
Rambus had no comment at press time. ยต
