I can tell you a little bit about that, although I think the best people to answer the question would be the companies that were involved in the negotiation. There were, I gather, some lengthy negotiations, though they were not required under CAMR. So at the time they didn't relate to the actual requirements of the regime.
The regime requires that when, say, Apotex notifies the company that holds the patent, it has to say it would like to do this voluntarily and ask if the company would agree to a voluntary licence. The owner of the patent has 30 days within which to reply. If they don't reply within 30 days, then Apotex or the generic company can go on to the compulsory regime. So there is a time limitation on that negotiation. And there might be no negotiation in that period. Once the 30 days runs out, you're on to the next steps in the process.
In the example of Rwanda, there were extensive negotiations, but they didn't relate to the timing that's built into the bill, which is really meant to limit that period and allow the generic company to move on to the next stage.
