Apple has patented almost all the products it sells and the iPhone 4 was not going to be an exception to the rule. The company recently received the news that a patent for the design of the iPhone 4 terminal was posted by the US Patent and Trademark Office. The patent certainly describes the design of the terminal, from absolutely all points of view, even the iOS interface that the device runs. Apple has a patent for all its models, but it also has one for Apple TV or Macs, for example.
Apple probably registers several hundred patents annually, but few of them end up being used for something, and this one will probably be used against Samsung or other companies that will produce smartphones similar to the iPhone 4.
