Ok. With the BSD + patent grant Do you have a license to use Facebook's patents? Yes. Do you have a license to use Facebooks patents if Facebook brings a patent case against you? Yes. Do you have a license to use Facebooks patents if you bring a patent case against us? No. If you do not have a patent grant, can you still use React? YES! If you're going to down vote this, please say why. This is how I interpret the license plus patent grant. If I'm wrong, I'd like to know why.

Its not talking about terminating the patent grant, its talking about terminating the license to use.

  > Its not talking about terminating the patent grant, its talking about terminating the license to use. This is totally incorrect, and has been debunked many time. "The license granted herein" is the patent grant, because that language occurs in the patent grant. The BSD license is totally separate. This has been stated, repeatedly, by representatives of Facebook and independent lawyers; the language is standard and unambiguous. They even answered it in a FAQ here[0]: Q: Does termination of the additional patent grant in the Facebook BSD+Patents license cause the copyright license to also terminate?

  The section you quite is under this one: >Facebook, Inc. ("Facebook") hereby grants to each recipient of the Software ("you") a perpetual, worldwide, royalty-free, non-exclusive, irrevocable (subject to the termination provision below) license under any Necessary Claims, to make, have made, use, sell, offer to sell, import, and otherwise transfer the Software. For avoidance of doubt, no license is granted under Facebook's rights in any patent claims that are infringed by (i) modifications to the Software made by you or any third party or (ii) the Software in combination with any software or other technology. Emphasis mine. So it seems to terminate just the patent grant. You can't terminate a BSD license so if you're in like France (no software patents) then you are fine to use React and sue Facebook for patent infringement.

No, you're quite right. The license to use React is governed by the BSD license, and it's not terminated if you end up suing Facebook over their violation of you VR patents or whatever. Edit: Downvoted for a factual answer? There's a host of sources confirming by answer as correct, including Facebook's official FAQ on React licensing[0]. Q: "Does termination of the additional patent grant in the Facebook BSD+Patents license cause the copyright license to also terminate?" A: "No." That's about as simple as it gets.

  Apologies for the dumb question, but what rights do you lose if the patent license is terminated? I mean, if you can use the software without the patent license, what is the patent license giving you?

    > I mean, if you can use the software without the patent license, what is the patent license giving you? Facebook may or may not have some patents covering concepts or algorithms used in React. If they do (nobody is aware of any), then they could sue you for using React, or any other framework which uses the same underlying concepts (eg, Preact, maybe Vue, possibly Angular 2.x, etc., depending on what the patents cover). If they did sue you, a valid patent grant (which you obtain by using React) would be a very strong defence, and would be quite useful. The value is real...but quite narrow in scope. :)

      I think the patent grant applies to everything you make, not just anything involving react.

        I'm not entirely sure what you're trying to say. The patent grant applies to Facebook's patents (if any) on the tech used in React. > I think the patent grant applies to everything you make Yes, if you have a patent grant from using React, it would be a defence from claims that things you have written that do not use React violate patents included in the grant.
