A patent filed by Nokia with the US Patent and Trademark Office describes a bendable device with a flexible screen. It's not simply that, of course, as we know phones with flexible panels aren't new. Remember thefrom Polymer Vision?
According to parts of the patent, the differentiating factor is that such a device will respond according to the shape a user puts it in. For example, bending it to resemble a can will cause it to do a search for a bar or pub in the neighborhood, while making it into the shape of a bowl will activate a search for restaurants.
It may look interesting, but don't get your hopes up for a foldable phone anytime soon. Lots of ideas get patented with nothing to show for it till many years later.
