SanDisk's patent complaint will get U.S. trade agency review

SanDisk, the world's largest maker of cards that store digital photos and other data, persuaded a U.S. trade agency to look into whether 25 companies are violating its flash-memory chip patents. The U.S. International Trade Commission said Thursday that it will investigate SanDisk's complaint, filed in October. Milpitas-based SanDisk wants the agency to block imports of products found to infringe its patents. Flash-memory chips are used to store data in digital cameras, cell phones and MP3 players.
