(Pocket-lint) - When we recently brought you news that Lenovo plans to once again resurrect the Motorola Razr brand, this time for a foldable phone concept, we didn't realise just how close to the 15 year-old original it will look.

But a patent application has surfaced that includes diagrams of a very similar-looking handset. It has a similar flip-phone body but instead of a top screen and numerical keypad, the display runs the entire length. And it folds when you shut the phone.

The application was filed at the end of last year with the World Intellectual Property Organisation (WIPO) and while it doesn't specifically mention the Razr brand, there is no mistaking the style of the handset.

It looks just like the Motorola Razr V3 we reviewed in August 2004.

As well as the long internal display, the patented phone has a second screen on the rear. Presumably, that will enable you to see incoming calls and texts without having to open the device fully.

There also seems to be a camera and fingerprint sensor, although we can't be sure of how either would work or their full specifications.

We should find out more during Mobile World Congress in Barcelona at the end of February. Pocket-lint will be there to bring you all the news and our first impressions live.
