Spansion on Friday filed three complaints against Samsung, alleging patent violations in a broad range of Samsung flash memory products that go into devices like tablets and smartphones.

Spansion filed a complaint with the U.S. International Trade Commission against Samsung for infringing on four patents. The company is seeking a block on the importation to the U.S. of devices such as MP3s, smartphones and tablets that use Samsung's allegedly infringing flash memory.

A Spansion spokesman declined to comment on which products those may be. However, Apple's iPad and iPhone 4 use Samsung flash memory.

Spansion also filed other complaints in the U.S. District Courts in the Eastern District of Virginia and the Northern District of California. In the court cases, Spansion is seeking damages to the extent of profits made by Samsung from the allegedly infringing products.

The patents mainly revolve around the manufacturing and operation of flash memory, said Mark Franken, a Spansion spokesman.

"It's important to protect our intellectual property and get rewarded for it," Franken said.

The complaints are part of ongoing action that Spansion has taken against Samsung in patent-infringement cases. Spansion originally filed complaints against Samsung with the ITC and in courts in November 2008.

Spansion emerged from bankruptcy earlier this year. The company was spun off from Advanced Micro Devices in 2005.
