That's a fantastic question, and I'm not going to pretend to know the entire answer to that. I don't know what the equivalent is in the EU for conditional registration.
You do have to keep in mind that if the EU rejects a product for registration, it becomes a very proponent- or registrant-driven approach, right? The regulators wouldn't necessarily go back and look at it again unless a registrant brought forward another application.
As for what the analogue is in the EU for conditional registration, I don't actually know that.
