They shall then be free for anyone to utilize. Public domain, for anyone's project. The only thing remaining under Amiga control will be copyright (of specific code, or order thereof), not the processes or ideas. One can then implement the same idea or working effects, but with their own code (not Amiga's). Any lingering disputes or stand-offs over the use of the old Amiga patents...will evaporate. Free and clear (even, perhaps, for Amiga Inc. itself, if it has anything unresolved there).
They, of course, have their name|brand, trademark, and copyrights (for specific sequences of code, and so on).
But 'work-a-likes' can then arise, without fear of lawsuit.
