That's always been the case, but this time it's a matter of not infringing Canon's AF patent. Samyang had to pull its reverse-engineered AF lenses off the market because of that and now it's got manual focus lenses only.

It's always been a case of not infringing on Canon's patents. Canon has never been indulging infringements on its IPs. If Samyang pulled its lenses, it's because Samyang knew they were infringing on Canon's IPs.

So, how did Sigma and Tamron manage to do what they did with EF mount? Is there a chance of buying licenses, or did the EF mount patents expire before they could do anything? (I hope for the first).

Sigma and Tamron were releasing EF lenses long before the patents related to EF expired. But the really great GV EF lenses from Sigma in the 2010s were released after expiry, as it happens.

Sigma also released a bunch of EF-M lenses.

I strongly suspect you will see Sigma in RF in the next few years. Even if Canon licenses it, though, I don't think they'll announce that deal publicly.
