Your analogy with a company processes doesn't quite work because patents works differently from copyright:

With copyright, you are allowed to use the original work as your own if you transform it enough (basically, you can get inspiration from it, but not exact copy).

With patents, you infringe a patent when you use the work described in it without the license, even if it's just as an inspiration and if you transform the method. It also doesn't matter if you rediscovered the content of the patent independently from the inventor, even if you can prove it.

So in this case, the original manufacturing company can defend its IP even if its work has been learned then rediscovered by an AI.
