I don't understand this: how are you not strictly better off with the patent grant? This whole fiasco seems to be nothing but FUD. See https://news.ycombinator.

I don't understand this: how are you not strictly better off with the patent grant? This whole fiasco seems to be nothing but FUD. See https://news.ycombinator.com/item?id=14780979 https://news.ycombinator.com/item?id=14780979 tl;dr: License with no patent grant: Facebook can sue you for infringing patents, even if you are using a clone! License with patent grant: Facebook cannot sue you for infringing patents, unless you do it first.

There are two camps - those who believe that an open source license implicitly provides patent grants and those who believe an open source license does not allow patent use. Until such a thing is tested in court (in each country) both ideas have merit. The patent grant is also worded a bit unclearly - implying that if you sue facebook you will lose the copyright, not only the patent right, to use React. Even though the lawyers clarified it in FAQ and other places, the wording is still what it is.

  > The patent grant is also worded a bit unclearly It's not unclear at all. Here's the file.

    The PATENTS file refers to all patents granted to you by Facebook in any project, not just in React (or any of the other files containing the PATENTS file). I think it's scoped a lot more broadly than you seem to imply.
    - notacoward 9y ago
      It refers to all patents as potential triggers, not as potential consequences, and that still doesn't allow a patent license to nullify a separate copyright license. I think it's scoped a lot more narrowly than you are trying to imply. I've provided detailed reasoning for my position. Feel free to reciprocate.

        Suing Facebook for an unrelated patent will make any software you use that may only work with ANY Facebook patented works useless. It doesn't discriminate to this project. They retain first strike however, so all the people saying this is great because patent litigation is bad, Facebook still has first-strike here. Also, the copyright license isn't useful unless you have complete knowledge of Facebook's patent portfolio and are certain that without a patent grant (implicit/explicit) you can still use the software at all. This goes for Facebook as well as immutable, graphql etc. > ... if you (or any of your subsidiaries, corporate affiliates or agents) initiate directly or indirectly, or take a direct financial interest in, any Patent Assertion ... This amounts to a sprawling amount of individuals/orgs that can make you rewrite everything.

        You're still assuming, contrary to all fact and common sense, that either the copyright license or the implicit patent license are affected in any way by what happens to the explicit patent license. I've explained elsewhere in this thread why that's not true. As long as you continue to base your argument on that assumption, without even acknowledging (let alone addressing) explanations to the contrary, that argument is a waste of everyone's time.

Why would it be unreasonable to assume that the explicit clause in a contract exists to override the implicit clause? Isn't that kind of the point of explicitly enumerating cases? Where, elsewhere in this thread, do you explain this? And your aggressive tone is unexpected. Edit: Also, I didn't say the copyright grant was affected, but if you don't have a grant to use a patent that the software flexes.... ? Being concerned vs. assuming flowers seems safer in untested legal waters.

The patent grant isn't the problem it's the termination on any action against Facebook. Hence if Facebook infringes on patents you own you can't take action against them if you are using React.

  I think it’s quite fair to say “don’t sue us if you want to use our stuff for free”.

  It's not "termination on any action against Facebook", the termination is only for: 1. filing a patent infringement against Facebook (for anything, related or unrelated to React) 2. filing a patent infringement counterclaim against Facebook for patents related to React (after Facebook have first filed a patent infringement claim against you for patents on anything) 3. filing a patent infringement against anyone for patents related to React [edit] > if Facebook infringes on patents you own you can't take action against them if you are using React. You can take action against them, you just don't have a patent grant once you do.

    > You can take action against them, you just don't have a patent grant once you do. Which opens you up to being countered-sued right? It seems that this leaves Facebook to freely infringe on any patents of React users without consequence.
    - Flenser 9y ago
      Only if they have a patent on [edit: something in] React, or on anything else that you use (regardless of it's from Facebook) [edit2] Also, patent lawsuits are costly. If you're going to start one against Facebook the cost of switching away from React first would be negligible.

      Not without consequence. You as a company will have to determine which is more of a problem: Facebook using your patents, or you using Facebook's patents.
