I noticed the response from Playsaurus' attorney, as well as stating why CH2 is not infringing, lays out arguments suggesting the 838 patent should not be valid.

I'm curious if someone familiar with the matter happens to be reading - is there any provision in the system for Playsaurus to now have the case taken the court regardless of the fact GTX did not infact file a lawsuit, i.e. attempt to have it invalidated even if GTX drop the threat of the lawsuit? Or would they need to piggy back / support one of the other companies listed in this blog?

Yes. They would arguably have standing to bring a declaratory judgment action, asking a court to invalidate the patent. They should also look for (now relatively common) state law provisions that provide damages for bad faith demand letters.

That would be pretty expensive though. Is why nearly any non-huge company is going to take someone dropping their claim as a huge victory, and not try to go to court anyway.

Yes, you can seek a declaratory action in federal court, and more recently, you can seek to invalidate with the USPTO's PTAB through an inter partes review (IPR).
