> I don't feel like it is fair that the company above would not be able to use React because Facebook infringed on a patent unrelated to React. Again, keep in mind that in your example, the company still has a license to use React. What you're losing is your explicit grant of a license to the patents Facebook MAY have on the technology. But nobody has ever identified such a patent, and one of the core React devs is on record as saying he isn't aware of any either.
