I cant see how any of it would matter at all. Most everything Amiga related has expired patents. What could any legal team even do at this point? 3.X is no longer being developed and whoever holds the rights should just make a public statement to have at it and improve on what you can. The community of developers that can even make use of this stuff is so small that it should be a no brainer to let them look and give back.
Copyright and patent law are not the same thing, but I don't know enough about either to explain the differences accurately, and I don't want to add to the confusion by trying. Perhaps someone else can take a stab at it.
