After being on the losing end of a prior court injunction by Apple in Australia last week, Samsung has fired back with an injunction of its own.
Samsung filed an injunction against Apple today in Japan and Australia. The company backs up its court action by stating that Apple's "iPhone 4S" violates several of its technology patents.
Samsung's legal action in Australia concerns Apple's patent use of wireless technology, including WCDMA and HSPA, in mobile devices. This matter has been taken up with the Federal Court in Australia.
As for Japan, Samsung is asking for an injunction against Apple for using its four patents that relate to HSPA and user-interface elements. The Tokyo District Court is handling this lawsuit.
Samsung feels that Apple Inc. continues to violate its patent rights and get a "free ride on our technology."
These court injunctions from Samsung are also targeting Apple's "iPad 2" and "iPhone 4."
Samsung previously filed an injunction against the sales of Apple's "iPhone 3GS" as well.
Both companies have been at odds with one another for quite some time now. A legal patent battle over the "Galaxy Tab 10.1" has been the main dispute between Samsung and Apple in the U.K.
Apple argued that the tablet copies its iPad. Last week, the Federal Court of Australia sided with Apple, and barred the "Galaxy Tab 10.1" from sale in the country until a full patent case can be heard.
In the Netherlands, the company has been forced to upgrade its "Galaxy S", "Galaxy S2", and "Ace" smartphones. This move was done so that Samsung can continue selling the devices after a court ruled they violated Apple patents.
In Germany, the "Galaxy Tab 10.1" has now been barred from sale. This is due in part to the alleged misuse of Apple patents.
Another ruling occurred before a U.S. district court judge in Northern California. The judge said that Samsung's devices do violate the patents Apple holds in the U.S. However, Apple must prove that the patents it holds are, in fact, valid.
So far, no sales injunction has been ordered in the U.S.
Samsung's recent legal woes have hurt the sales of its smartphone and tablet devices.
