It would appear that Samsung is tired of getting kicked around by Apple in the courts. The very next day after Apple's big announcement of the iPhone 4S, Samsung is filing a suit to block the sale of the device in France and Italy. The suit claims that Apple has been violating a number of Samsung patents all along, but now Samsung is finally coming forward with it. Samsung plans to file similar claims in several other countries as well.
The suit claims that Apple violates two of Samsung’s patents related to WCDMA standards for 3G-enabled devices. Here is Samsung's comment on the suit,It's like World War III fought in the courts...“Apple has continued to flagrantly violate our intellectual property rights and free-ride on our technology….We will steadfastly protect our intellectual property.”
