No argument there, friction drives are one of the oldest applications for transfer of power and highlighted on that eBike version at the link you posted with the patent schematic from 1899.

But strictly speaking, I wasn't referring to the patent process or it's justification in my comments above but more toward the mention of a mechanical device being described a vendor and the subsequent confusion it fosters as shown in the opening of this thread.
To me, that's patently misleading.
