Given the impact the world has already seen because we let two companies tie up LiFePO4, after we let a few companies tie up other battery patents for hybrids before that...

TBH I would judge the world if they just went ahead and 'stole' it vs RAND licensing...

At the same time, I can see it being one hell of a hypothetical 'carrot' for lots of things, and of the current major powers, China is the only one with enough overall (political+humanpower+etc) will (at this time, anyway) to possibly make Fusion happen sooner than ITER can.

Strategically speaking, it would 'make sense' for them to pursue... Would the European union force NL's hand, to make ASML sell machines for whatever comes after EUV, in exchange for Fusion tech? Or all sorts of other fun things for the right Q factor?

Things become murkier.
