MSFT don't have OpenAI's IP. They have an exclusive right to some of it, but there's presumably a bunch that's not accessible to them. Again, business continuity is easier if they can just grab all of that and keep everything running as normal.
Satya Nadella just did a podcast with Kara Swisher.
In it he specifically said, "we have all of the IP rights to continue the innovation".
But Satya made it crystal clear that in the event that OpenAI stopped all development tomorrow, Microsoft would be able to pick up from where they stopped. That requires full access to all of the IP.
Whether it's perpetual is irrelevant because at the point at which Microsoft pulled the trigger it would effectively be like a fork. Any IP from that point is new and owned by Microsoft.
Appears from what? I've seen this stated several times, usually citing nothing and occasionally citing a Nadella statement from which it would be a very tenuous inference.
The statements I've seen don't match what is claimed, which is why I asked for one that did.
a) If it wasn't exclusive then we would have seen some other product besides Bing with this technology by now.
b) Satya has specifically stated that in the event of a breach in contract with OpenAI they have the ability to use the IP to continue development. That clearly indicates it is irrevocable.
And they could clone the entire OpenAI Azure stack in about 10 minutes.
Yep, those lawyers can be just as crafty as developers believe it or not.
*edit: just saw it claimed below Nadella said "we have all of the IP rights to continue the innovation"*
I don't know!
