An extended Routing Policy Specification Language (RPSL) permits registry of independent routing policies for different Internet Protocol versions, while being compatible with existing RPSL.

RPSL is also extended to permit separate handling of multicast routing policies in any protocol, by including subsequent address family indicators (safis).

- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 17, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
