PC and printer major HP, which once experimented with phablets, is reportedly working on a clamshell foldable smartphone similar to the Samsung Galaxy Z Flip. The company patented a design for such a smartphone with the WIPO (World Intellectual Property Organization) and the patent was approved last month, reports LetsGoDigital. The HP patent describes a technology for applying flexible screens to mobile devices such as smartphones, tablets or computers. Although similar to the folding method of the Samsung Galaxy Z Flip, the HP patent describes it as ‘using a movable hinge that can be folded in different positions’ and is not limited to folding in half. However, it is not necessary that HP would launch such a product in the market. In 2016, HP Inc unveiled Elite x3, a 5.96-inch touchscreen device that ran Windows 10 Mobile and supported Continuum, a feature that allowed the device to be attached seamlessly to a separate screen, mouse and keyboard.
