A patent application is not a product (let alone a patent), but it’s worth noting that Samsung’s been revealed to have filed a few applications about wristwear interfaces. The filings, uncovered and collected by SammyToday and better explained by 9to5Google, seem to cover a lot of UI ground: the appearance of screens and interesting ways of interacting with the device using hand gestures.
That the device in the patent drawings looks an awful like pictures of the Moto360 Android Wear device is probably coincidental. Round watchfaces are probably not patentable (although the way the USPTO’s been going it wouldn’t surprise us if someone tried).
