U.S. court finds in Rambus' favour in Hynix case

* Court affirms jury ruling in favour of Rambus

SAN FRANCISCO, March 4 (Reuters) - A federal court judge, upholding a jury’s 2008 decision, ruled on Tuesday in favour of chip designer Rambus (RMBS.O) in part of a long-running dispute with South Korea’s Hynix (000660.KS).

U.S. District Court Judge Ronald Whyte confirmed a March 2008 jury finding that Rambus was not required to disclose its intention to file patents to a standards-setting organization that Hynix was also a part of.

That buttressed Rambus’s position that it rightfully held key patents.

Judge Whyte’s decision may have some bearing on court-ordered negotiations now underway in Seoul between Hynix and Rambus on a license for the DRAM patents in contention. They are due to present the terms of the license on March 9.

Rambus was a member of the standards-setting organization JEDEC from 1991 to 1996. It did not apply for the contended patents until three-and-a-half years after it resigned its membership.

“The evidence suggests that the scope of a JEDEC member’s expectation of disclosure ranged from non-existent to astonishingly broad,” wrote Whyte.

“The jury found that the JEDEC members did not share a clearly defined expectation that members would disclose relevant knowledge they had about patent applications or the intent to file patent applications.” (Reporting by Clare Baldwin; Editing by Edwin Chan)
