The U.S. International Trade Commission has decided to investigate Apple’s allegations against Motorola. In October, the two handset makers accused each other of patent infringement. Apple charges the Schaumberg, Ill.-based Motorola violated six multi-touch patents.
If the ITC rules in Apple’s favor, importation and sale of Motorola smartphones could be banned in the United States. The patent spat erupted in early October when Motorola accused Apple of violating 18 patents and refusing to agree to license Moto’s technology. Apple fired back in late October, claiming Motorola had violated its patents.
