If the requirement is written in to law then the US Constitution (or other such documents granting exclusive use to an idea) must be amended to void any patent which prevents competition to meet that requirement. Volvo[1] is the a good steward in this regard, seat belt laws cover most people but the technology itself is free to implement by anyone. That's how it should be. If you can patent something that the government then mandates be included your patents must be invalidated (or you do what Volvo did voluntarily).
