I don't see "removing" the patent as viable. The guy did invent it, and it is his intellectual property. Saying it should be required is an opinion. Changing tracks on this, what about air bags. Yes, cars have them, but side curtain airbags are not in all cars and are an option. If you didn't elect to buy a car with side airbags, is the car company liable? Just a perspective, not really a question.
