Samsung Electronics filed preliminary injunction motions in Japan and Australia on Monday to block the sale of Apple's iPhone 4S there.
The South Korean company is accusing Apple of patent infringements dealing with wireless telecommunications technology.
In the Japan filing, Samsung also wants the court to bar the sale of iPhone 4 and iPad 2.
Apple could not immediately be reached for comment.
Apple announced the latest incarnation of its smartphone - the iPhone 4S - on October 4.
The next day, Samsung filed preliminary injunction motions in Italy and France to ban its sale in those countries.
