Apple Inc. won a total number of 18 patents which were granted by the US Patent and Trademark Office, among which also the iPhone 4 Design Patent as well as the RFID patent.
The unique nitriding stainless steel ban found on the iPhone 4 has won a patent for Cupertino. It is a signature as well as a statement to the new design — if coming from the iPhone 3GS — and Steve Jobs is credited among other people like Jonathan Ive and fifteen more.
As far as the RFID patent is concerned, the technology will allow users to action on RFID tags using the sensor built into the touch sensor panel. Use case scenarios vary from wireless transfers of data from an iPhone to a desktop to opening keyless hotel or car doors. RFID technology will be built into future iOS devices — so iPhone too — adding yet another set of functionalities to the table.
Without getting into details, other patents refer to iTunes, Apple TV and a design patent for the 2007 iPod Touch.
