Thanks, Anthony. Just remember that the “controversial” part of FB’s React license only applies in scenarios where you first sue FB for infringing your patent. I’m not sure it’s fair to say FB is trying to “tie you up in court and bankrupt you” in such a case. They’re just defending themselves in a lawsuit you started (and “all’s fair in love and war”).
In any event, I do generally agree that if you start a patent battle with FB (or any big co.), expect them to use their IP portfolio to fight back. The ‘React patents’ are likely a small % of FB’s total portfolio and, once attacked, I’d expect them to use anything they can (React-related or otherwise) in their defense.
