Samsung has filled preliminary injunctions agaisnt Apple's iPhone 4S in Japan and Australia, after facing a hard time in three patent battles last week. If Samsung has its ways, both Japan and Australia may remain devoid of the taste of the new iPhone.

Samsung is, reportedly, citing four infringements in its Japanese lawsuit – one because of High-Speed Packet Access (HSPA) and three on user interfaces. The Korean giant wants to stop the sale of the new iPhone 4S in both countries and also ban sales of the iPhone 4 and iPad 2 in Japan.

Samsung has made their patent claims very clearly, saying the company’s preliminary injunction request in Australia cites three patent infringements related to wireless telecommunications standards, specifically Wideband Code Division Multiple Access (WCDMA) and HSPA.

“Method and apparatus for transmitting/receiving packet data using pre-defined length indicator in a mobile communication system (WCDMA),” the company’s Tomorrow blog said, “Method and apparatus for data transmission in a mobile telecommunication system supporting enhanced uplink service (HSPA),” and “Method and apparatus for transmitting and receiving data with high reliability in a mobile communication system supporting packet data transmission (HSPA).”

The patent claims come just after Samsung’s new Galaxy tablet computer was temporarily banned in Australia, following an Australian court's decision last week. The Korean company was accused of copying the iPad and iPhone which violated Apple's patents.

“In light of these violations, Samsung believes the sale of such Apple devices should be banned. Apple has continued to violate our patent rights and free ride on our technology. We will no longer stand idly by and will steadfastly protect our intellectual property,” the company further added.
