We all know a bit about Samsung and Huawei's attempts to develop a foldable phone. However, LG's plans have been flying under the radar. So far we have heard very little about the device, which makes three recent LG trademarks that appear to relate to foldable phone all the more exciting. As spotted by LetsGoDigital (via Engadget ), the company has applied to trademark the names Flex, Foldi and Duplex. LG made the applications on November 21 at the European Union Intellectual Property Office. We don't know for sure if these names relate to foldable phones, though the category LG made fillings includes smartphones. Considering we know LG is developing a foldable phone, it seems pretty likely that this is what the trademarks related to. Of course, even if the names do relate to phones, it doesn't mean one of them will be used for final device ( if that were the case, we'd all be familiar with the LG G Edge phone and its Super Edge display by now)...
