After Samsung showcased it $2,000 foldable smartphone here, Apple has submitted a blueprint of a bendable smartphone at the US Patent and Trademark Office, indicating Apple's progressive development towards building a foldable device.

The patent application describes a display with hinges that can fold in half or in thirds. The display could be used in anything from phones and tablets to laptops, wearables and even mobile accessories, The Verge reported on Thursday.

Speculations surfaced in 2018 that Apple could bring a foldable iPhone in 2020, which would be able to double up as a tablet.

"Apple's design plans were filed back in October and the patent application only means the idea is out there and hasn't been approved yet," the report said.

Ushering in the foldable smartphone trend, Samsung on Thursday officially launched its "Galaxy Fold" smartphone priced under $2,000.

A lot of companies, including Microsoft and Huawei, are working aggressively on their foldable devices.

While Microsoft recently filed for a patent showing a device mechanism that allows a single display to be folded shut by a hinge from the inside of the device, Huawei has also confirmed it plans to launch a 5G foldable phone, likely during the Mobile World Congress to be held in Barcelona next week, the media reported.
