Name the product, then the detail that reframes it. The foldable conversation is dominated by two parts: the hinge and the screen. But a phone is not just a screen and a hinge — it is two halves full of electronics that must stay electrically connected across the fold. Granted patent US11194367B2, "Foldable device and method for disposing flexible cable," issued December 7, 2021, claims exactly that overlooked problem: how to route the flexible cable so it survives folding too. Its CPC class G06F 1/1683 is the internal-construction class for portable devices.
What it costs, who owns it. The flex cable carries power and signal between the two halves; it bends every time the phone folds, just like the screen. If it is routed badly, it fatigues and fails — a dead foldable that looks fine on the outside. The bend-survival problem the industry obsesses over for the display applies equally to the wiring, and far fewer people think about it.
Three records, one fold: the hinge patent controls the mechanism, the display patent protects the panel, and a cable-routing patent like this keeps the electronics alive. A durable foldable needs all three solved at once, which is why reading only the hinge or screen IP gives an incomplete picture of who can actually build one that lasts.
The strategic read is that foldable reliability is a systems problem distributed across many small, unglamorous patents. The companies that ship durable foldables are the ones that solved the whole stack — including the boring cable-routing problem — not just the headline hinge.
Scope, stated plainly: this is a granted patent to NEC Platforms on a specific cable-routing method, within a broad foldable-construction landscape. It is one piece of the durability puzzle, not the whole of it.
Follow the filing, not the spec sheet. The reason one foldable outlasts another often lives in details that never get marketed — like how the flex cable is routed across the fold, the problem this 2021 grant addresses.
