You get sued out of existence for damages.

This case? The supreme court made the president untouchable as long as it can be claimed as an official act, and he said it during a white house press conference so it will be deemed an official act.

So after their entire legal department quit rather than be associated with a case against the supreme leader, they'd find an ambulance chaser to file the lawsuit and trump would look at them like south African diplomat from leathal weapon 2 and say "presidential immunity" then the FDA and CDC would launch health and safety inspections and the IRS would audit the company and every employee from the CEO to the janitor in Booger Hole, WV.

Your question is the kind of thing I expected to find out with my own comment, but the answer barely matters when it comes to whether they will take action or not. Either way its their product originally, something they invented/discovered.
