What patent portfolio does Nokia have to develop mobile phones?

Apple, Samsung, Sony, Microsoft and so on give patents to Nokia every year. That's true. It's a good life. Although many of them are old patents, after all, although mobile phones have evolved for many generations, many things are still passed down from generation to generation, so those old patents registered early are even more unavoidable for other mobile phone manufacturers. As for asking what patents Nokia has. It's a little difficult to find this more than 10 thousand First of all, Nokia is one of the main owners of 2G patents. In the 3G era, Nokia has a large number of WCDMA patents, while in the 4G era, Nokia actively participated in LTE R&D and has a considerable number of LTE patents. The authorization signed with LG a few days ago is in this respect.
