Infineon denies this and alleges that, in any event, Rambus does not own the intellectual property in these patents and that its lawyers illegally manipulated Rambus’s existing RDRAM patent, several years after the original filing, to include SDRAM technologies.
Infineon also claims that Rambus failed to submit details of existing patents and prior art in filing amendments to its patents with the US Patent and Trademark Office, and then tried to hide certain patent applications from the chip industry’s standard-setting body, JEDEC. Infineon claims that Rambus stole information from JEDEC committee meetings and used it in its patent amendments, thus giving it control of industry standard SDRAM technology.
