The Electronic News has obtained internal memos, e-mails and a business plan from Rambus Inc. that the publication says reveal Rambus’ secret scheme “to take over the global DRAM intellectual property business.” Electronic News won access to the documents, pertaining to the ongoing legal battle between Rambus and several memory makers, after filing a motion with the US District Court of San Jose. According to Electronic News, many of the documents bolster the impression that Rambus deliberately violated Joint Electron Device Engineering Council (JEDEC) rules by not disclosing its patent intentions. If proven, the Rambus DRAM patents could be overturned.
For example, the 1992 Rambus business plan would seem to contradict claims by Rambus that it was engaging in full disclosure with regards to JEDEC. The document says, “Finally, we believe that Sync DRAMs infringe on some claims in our filed patents; and that there are additional claims we can file for our patents that cover features of Sync DRAMs. Then we will be in a position to request patent licensing (fees and royalties) from any manufacturer of Sync DRAMs. Our action plan is to determine the exact claims and file the additional claims by the end of Q3/92. Then to advise Sync DRAM manufacturers in Q4/92.”
DRAM makers, however, say Rambus representatives did not reveal their plans until after 1997. A Rambus Inc. press release, though, says “It is irresponsible and misleading to view any document out of context and without seeing all the evidence.” Additionally, the release asserts, “We look forward to an expeditious recognition of Rambus’ innovations in court.”
