I think you're right but the patents apply mostly to smartphones. That's a much bigger market for Xiaomi than fitness bands.
In any case despite possible patent infringement you can buy Mi Bands, at least the previous models, from US-based "store-fronts" like Amazon.com, e.g.

I don't see any Mi Band 2 models for sale yet on Amazon but I imagine it's only a matter of time.
