Patented Apple Battery Charger For his gadget

US Patent and Trademark Office or the Office of the United States Patent and Trademark Office published an article on "Charging for the device" Apple, his Patent is about making an inductive charger, which can be done on devices from Apple such as Apple smart watch or bracelet.
From the illustration shows a small wire that connects the battery to the rope to the back of the device. The rope was really thin, which allows both comfortable when worn and look more fit when used.
No one knows if they will be used up to a real product or not. But Apple only protect this idea that can not be used by other companies.
This idea is quite interesting because of smart watches Apple really is not round, but square. Apple is often used illustrations to expand the generic patent application or actually show a design that later was not marketed.
