Both Samsung and Apple have filed new patent infringement suits against each other in France and the UK, respectively. Samsung’s suit, filed in a Paris district court, accuses Apple of infringing three Samsung patents related to UMTS technology, and specifically targets the iPhone 3G, iPhone 3GS, iPhone 4, and 3G-enabled iPad and iPad 2 models. Apple’s suit against Samsung was filed in the UK; details on it are scarce, as the patents in question have not yet been identified. Finally, Samsung has also filed an appeal against a German ruling from last week that saw sales of its Samsung Galaxy Tab 10.1 tablet barred in the country. Samsung and Apple are involved in a large number of patent disputes worldwide.
