If LK-99 turns out be a legit room temp superconductor I can't see traditional patent/IP rules applying to it. The value to our species to too high for a technology like that to be encumbered. I would think a very large lump sum payment to the patent holders would be sufficient to cover everyone's interest.

Otherwise I fully expect every government in the world to simply ignore the patent and allow public/private use -- effectively invalidating the patent.

There is existing precedent for this type of action: the US government seizing wireless patents during WW1 or the Indian government invalidating international patents on medication for the purpose of federal manufacturing.
