    “If you bring a patent claim against any contributor over patents that you claim are infringed by the software, your patent license from such contributor to the software ends automatically.”

    My interpretation of this was “if you sue us for infringing your patents, we won’t let you use any of ours”, but I”m still stuck on the “your patent license from such contributor” bit.

    I am a non-native speaker as well but I think it means that if someone wanted to attack the code uder such license because it, according to someone, incorporates some patents, someone would lose all patents licences from the creator of the code. Which seems fair to me.

    It’s not because you’re a non-native English speaker. That language is convoluted and confusing for me as well. It basically sounds like a threat, though… “If you sue us, you have to stop using our software, or we’ll sue you too.”

  4. Alex H says:

    That clause is actually relatively simple. Both licenses have a “Patent Grant”: each contributor to the software grants everyone a patent license to any patents you’d otherwise infringe.

    The “patent claim” text is saying, “If you sue another contributor for patent infringement, your patent licenses from them are revoked”. The reason you’d want to revoke their licenses is so that the contributor can use that patent to defend themselves.

    I wish that lawyers could start using language that is easier to understand for native English speakers.

    I’m in agreement with Wolfger and Dorian. Furthermore, I’m used to legalese (I’m acquainted with a few lawyers) and it’s just plain twisted.
