No matter what you think about the notched Nokia 5.1 Plus (you like the notch, you hate it or you don’t care about it at all), you will have a hard time to prove that the notched design was stolen from Apple in a court. At least in the EU, where HMD Global was granted two new design patents.
On 15th October EUIPO registered and fully published HMD’s design patent for the Nokia X5, globally known as Nokia 5.1 Plus. We can recognize that it is the X5, because of the wide notch and camera housing with flash below the cameras (compared to X7 with wide notch and flash next to cameras).
The designer of the patented design under number 005256740-0001, submitted on 14th March, is Yamn Chau, former Nokia and Microsoft designer, who also worked at Motorola and Micromax. Apart from the X5, HMD Global has two more patents of notched Nokia devices, that look practically identical. They were registered and fully published months ago, and it seems to be the Nokia 6.1 Plus, but the new Nokia 7.1 looks completely the same on the sketches so it could be the 6.1 Plus and 7.1 both.
HMD also got the design patent for Nokia Pro wireless headphones. The Pro wireless headphones, that come as the successor to Nokia Active headphones, were submitted to EUIPO on 14th February and registered and fully published on 11th October. The design number is 004707727-0001, with designer Kevin Depape.
HMD’s latest design patent was added on 24th September, and apart from that we don’t know any other info about it, except the design number (005654910-0001).
