With respect to why it took Apotex a further year after the authorization or licence, you'll have to ask Apotex that; unfortunately, I'm not in a position.
I can say that within three weeks of the original request, we responded to them to say that we were willing to discuss a voluntary licence, but we did not hear back from them. Three months later, we rewrote them saying that we had not heard from our original request and asking whether they wanted to speak with us. It took until July of the next year—from the previous September—to get yet another request, and 26 days later we told the commissioner of patents that we were willing to abide by the rules of CAMR and allow for authorization of our product.
As to why it then it took a year after that, unfortunately I'm not in a position to respond.
