Samsung SDI has filed a lawsuit against Japanese rival Matsushita Electric Industrial in the United States, seeking to nullify the Japanese flat panel maker's patents, according to report in

The suit, said to have been filed earlier this month, is the latest escalation of a dispute between the companies over basic intellectual property for the manufacture of plasma display panels.

According to the report, the two groups entered negotiations in 2004 after Matsushita claimed that Samsung SDI was infringing its patents. But they failed to reach an agreement and broke off the talks in late 2005.

Samsung SDI then fired the first salvo in the United States with a lawsuit that was quickly denied by Matsushita, who counter-sued, again in a U.S. court.

In the latest move, Samsung is said to be seeking a U.S. court ruling that the patents are invalid, to ensure that it does not have to pay royalties to its Japanese rival.
