Apple 3 years ago filed for a patent of ‘portable multifunction device’ together with a multitouch interface, the USPTO has finally awarded the patent which could raise suspicion in the competitors. With today’s capacative touchscreen which work like a sheet of glass uses the human touch then a response is given to it.
The manner in which this patent was worded is that all of multi-touch interface that are made in this manner belong to Apple according to the patent. This can be hefty to the competitors that use this technology. The patent is only to used for Apple’s products, not to make the competitors pay the fees.
