I’m not familiar with open sourced code under MIT that is still protected by a patent. Can you share some examples of this?

Technically not under MIT, but x264 and x265 are being developed despite the underlying technologies under it have patents.

In practice it means that development work still happens, and, and prebuilt redist binaries still get made, but only in countries that don't recognize software patents.
