Hitachi heeft een aanklacht ingediend tegen Rambus Inc wegens schending van de Sherman Antitrust Act. Deze actie volgt op de eerdere rechtszaak die Rambus Inc. tegen Hitachi heeft aangespannen. Rambus is van mening dat de clock timing technologie in de Hitachi SDRAM chips en SH-x processors is gebaseerd op door Rambus Inc. gepatenteerde technologie. Volgens Hitachi heeft Rambus Inc., in strijd met de JEDEC reglementen, patent aangevraagd op een technologie die op dat moment in bespreking was binnen de JEDEC (Joint Electron Device Engineering Council, clubje fabrikanten dat open standaarden ontwikkelt):
In its filing, Hitachi charged that Rambus has attached conditions to its Direct RDRAM licenses by requiring companies to license other technology before granting access to its memory-interface. Hitachi claimed such a practice violates provisions of the Sherman Antitrust Act.Hitachi asked the court to nullify the Rambus synchronous-chip patents, citing prior invention in the industry. The brief also said that Rambus participated in industry JEDEC standards meetings in the mid-1990s involving synchronous ICs, and gained access to technology it later patented in violation of JEDEC open-standards rules.
"Rambus used that information to revise secretly its then-pending but undisclosed patent applications and to prepare related additional applications to cover the very technology and potential standards being discussed by other JEDEC partcipants," the brief stated.
