The US International Trade Commission has officially agreed to investigate a patent infringement allegation against Apple, submitted by Taiwan's Elan Microelectronics. The two companies have been involved in a long-running legal dispute, as Elan accuses Apple of violating patents related to multi-touch technology. On the basis of one patent, Elan in late March filed a motion with the ITC to block US sales of infringing products, potentially including the iPhone, iPad, iPod touch, MacBook and Magic Mouse.
