A long-running patent dispute between memory chip maker Infineon
and chip designer Rambus came before a US court yesterday. Rambus

similar memory technology.
A long-running patent dispute between memory chip maker Infineon
and chip designer Rambus came before a US court yesterday. Rambus
claims that Infineon infringed four of its patents for SDRAM and
similar memory technology.
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.
