Updating Our Open Source Patent Grant
[Lawyer, but not a patent lawyer]<p>I was perplexed by the uproar on HN about the original patent language (in the thread announcing the release of React Native [1]). This kind of open-source patent license--which, in effect, allows Facebook to use its patents against users of React defensively but not offensively--is exactly what we need more of in the open source world. Why did people think that their defensive patent license was somehow worse than the industry standard (the MIT or BSD copyright license with no patent license, which made patent rights murky at best)?<p>But this new language eliminates the major limitation on the original language, which was that the license would be terminated if you attempted to invalidate one of Facebook's patents or defensively argued that it was invalid or unenforceable (or even, according to a strict though implausible reading of the language, if you publicly stated that the patent was invalid).<p>Glad to see Facebook paying attention, even if the original complaint was overblown.<p>[1] <a href="https://news.ycombinator.com/item?id=9271246" rel="nofollow">https://news.ycombinator.com/item?id=9271246</a>
