Dow Jones Newswires Monday afternoon is reporting that the U.S. International Trade Commission is investigating several firms that make or use NAND flash memory chips, including Samsung (OTC:SSNLF), the world’s largest maker of NAND flash memory chips; Research in Motion (RIMM); and Apple (NASDAQ:AAPL), following a complaint filed with the ITC in July by West Conshohocken, Pennsylvania-based BTG International.
The BTG complaint, filed on July 27, alleges that Samsung’s chips, and chips used by Apple and RiM and others, infringe on patents BTG holds on “MLC” type NAND flash memory chips. The suit requests the ITC ban Samsung’s chips and any products using them from being brought into the U.S., and for a cease and desist order to be placed on any of the companies’ business relating to those devices. The complaint specifically refers to MP3 players, digital cameras and other classes of device that infringe by their use of NAND flash memory chips.
The complaint in July followed two suits filed by BTG, one against Samsung, back in December of last year, and another against Apple, RiM and the rest in July, according to the ITC Law Blog, which has a link to the various documents.
