Samsung SDI said early this week (Dec. 7) that it has filed a civil lawsuit against Matsushita Electric of Japan in U.S. federal court alleging that the Japanese consumer electronics giant and its U.S. subsidiary infringed Samsung's plasma display patents.

The lawsuit between the world's two largest PDP makers underscores the intense competition unfolding in the booming PDP market.

A U.S. government mandate scheduled to take effect in March 2006 requires that all TVs measuring 25 inches or larger sold in North America must incorporate a digital TV tuner. The mandate is expected to boost demand for large, flat screen TVs, creating explosive demand for PDPs.

In a statement, Samsung said "We filed with a U.S. federal court in Los Angeles as North America is the biggest market for digital TVs."

"We have been in talks with Matsushita of Japan for nearly one year to reach a settlement, but failed to do that."

Samsung SDI alleges that the Matsushita violated seven of its PDP-related patents. Samsung is the world's largest PDP maker with about 29.5 percent of the global plasma panel market during the third quarter of 2005, according to market researcher iSuppli.

Matsushita is the No. 2 panel maker with 27 percent of the market. The company makes the Panasonic brand of consumer electronics.

Global PDP TV shipments are forecast to jump to 8.2 million units in 2006 from 5.2 million units this year, according to market researcher Display Search.
