Which specific "Nokia/Microsoft" patents do you mean? From my understanding, when Microsoft purchased the mobile phone business unit from Nokia, they did not receive any of the Nokia patents for mobile phone technology.
Nokia retained its patents and Microsoft got a 10 year license to use them. Nokia is free to offer a license to other mobile handset makers. Many mobile phone patents have applications not just in the mobile handset area, but also the Network Infrastructure and Mapping (HERE maps) parts of the business which Nokia still own.
However, there might be third party patent licensing deals that were transferred to Microsoft.
Microsoft HoloLens appears to be post Nokia (and not mobile specific either for that matter) and not related to the above.
