Is there any risk here of violating copyright or patent protection held by Notion.so?

Copyright protection is unlikely, unless they're literally copying Notion's code somehow.

Patent protection would traditionally be "unlikely", however with US having been accepting (totally worthless) software patents for a few years now it might feasible. But that would probably rely on Notion having gone through the process of patenting things...
