* Apple, Nokia, Samsung, RIM accused of infringement
* Spansion says companies use infringing Samsung chips
* Products in question include music players, phones
WASHINGTON, Sept 7 (Reuters) - A trade panel which probes patent infringement allegations agreed to look into whether Apple, Nokia, Samsung, Research in Motion and others infringed Spansion’s patents for flash memory chips.
The U.S. International Trade Commission said on Tuesday that it would take up a complaint by Spansion Inc CODE.N that the companies infringed four of its patents.
Spansion said last month in filing the complaint that it would seek to have some music players, cell phones, digital cameras and tablet computers barred import into the United States if they were made with the infringing technology.
Samsung Electronics Co Ltd (005930.KS) is named in the suit because it makes flash memory chips that Spansion says infringe its patents.
A related action has been filed in U.S. district courts in California and Virginia.
In 2008, Spansion filed a similar suit against Samsung, and purchasers of its chips. That suit, which involves different patents, should have an an initial determination from a trade commission judge in mid-September. (Reporting by Diane Bartz; Editing by Tim Dobbyn)
