Microsoft patents new hinge design that may revive Surface Duo smartphone

Microsoft has filed a new patent for a unique hinge design that could signal a return of the Surface Duo folding smartphone. This design differs from the typical "water drop" hinge used in most foldable devices. The new hinge features sliding and flexing sections, unlike the previous Surface Duo models, which had two separate screens. The patent suggests this hinge could also be used in other devices, possibly laptops, but emphasizes its application in smaller devices. This patent follows previous hinge concepts from Microsoft aimed at improving durability and addressing user preferences for thinner devices. The Surface Duo 2 was released in 2022, with software support ending in late 2024.
