SawStop actually granted Bosch a license to their safety patents for Reaxx some time ago. Moreover, they said during the hearing that they'd offer permissive public licensing to their remaining patents should this rule be made effective.
And imagine if this law passes and Saw Stop has monopoly on table saws. Sure, today you can buy one for $900 but nothing will prevent them from raising that to like $5000 when nobody else is allowed to build a table saw.
The patent system is not very compatible with highly regulated markets, it changes the game from choosing to buy something innovative to a non-voluntary overreach.
But it wasn't used to stop sawblades. How to reliably detect flesh without too many false triggers, do it fast enough, on a spinning blade, and as part of a complete system that includes the brake and actuation mechanism. That's what the patent is about, not the vague idea of using electricity to detect flesh.
It sounds incredibly naive to think this will happen. If they haven't done it so far why would they do it when the government mandates that you have to be their customer?
