A startup founder and ex-Facebook engineer’s story of the BSD + Patents license
> As part of the patent grant, you’d have to stop using Facebook open source upon claiming patent infringement.<p>IANAL but I don't believe this is correct.<p>If I'm using React and I decide to sue Facebook for infringing some other software patents I hold, I lose the <i>patent grant</i> for any <i>potential</i> patents Facebook might hold concerning React. Which they could go after me with if they do indeed hold such patents. There's nothing proactively forcing me off React.<p>I just don't see anything but good from this BSD+patent grant situation. It lessens software patent litigation in general and lets me know I'm safe from Facebook suing me specially. It seems fantastic!
