No, if you try to sue them for violating that patent, they can try to sue you for using React - if they actually have valid patents that cover React, that is. I doubt IBM's lawyers are breaking a sweat.

Why do you keep spreading FUD about this stuff even after Facebook withdraws the license?

Furthermore, this is all untested in the courts. Contracts and laws aren't really worth much until they're tested in courts. It's arguable that giving someone a license to use your code also gives them a license to use the patents that code uses. Kind of like how you're not infringing on iPhone patents if you buy and use an iPhone.
