Tridgell Recommends Reading Software Patents

H4x0r Jim Duggan writes "Andrew Tridgell rejected the common fears about triple damages: 'If you've got one lot of damages for patent infringement, what would happen to the project? It's dead. If it gets three lots of damages for patent infringement, what happens to the project? It's still dead.' Tridge then explains the right way to read a patent and build a legal defense: 'That first type of defence is really the one you want, it's called: non-infringement. And that is: "we don't do that. The patent says X, we don't do X, therefore go away, sue someone else, it's not relevant for us." That's the defence you want. [...] Next one, prior art: [...] Basically the argument is: somebody else did that before. It's a very, very tricky argument to get right. Extremely tricky, and it is the most common argument bandied about in the free software community. And if you see it in the primary defence against a patent, you should cringe because it is an extremely unsafe way of doing things.' There are even some tips in the talk specifically for Slashdotters."

    When I'm writing code, I don't have to worry about patent infringement, because the stuff isn't patentable. That way I can write code just like you write anything else; without looking over your shoulder.

      In the meantime, we can keep spreading the ideas of IP abolitionism, encouraging people to ignore it when they can get away with it and to push for legal change. A movement is important when fighting such established interests - buying or convincing one politician won't really do (and isn't really doable on this issue)

      There are countries in which there are no software patents. But the copyright law still applies.

      Remember that software patents are basically non-existant in Europe..
      Growing food is labor intensive, so it cannot be truly free(*), software patents are only a self-inflicted wound.

    Many patents are there not for suing the ass off the competition but to protect yourself from getting attacked.

    Which only became a problem with the invention of patents in the first place and keeps getting worse.

    Because it is as close as anyone is going to get as far as logical watertightness goes. Let P be "You are using a patented idea" and Q be "It's been done before". Enforcing a patent requires P.

    Patent owner: "P is true of you." (Initial threat)
    You: In fact Not-P is true of us.
    Patent owner: OK, Not-P so we can't enforce patent.

    vs

    Patent owner: "P is true of you."
    You: P is true but Q is true also. (You try to stop legal wrangling with Q.)
    Patent owner: OK, P so we can try to enforce patent, regardless of Q. We'll try to show Not-Q.

    Many patents are there not for suing the ass off the competition but to protect yourself from getting attacked.

    And since free software competing with yours is definitely an attack, why not attack? The very idea of patents, after all, is to encourage people to share their inventions by protecting them from competition in turn. That failed miserably, but can't be helped anymore, there's too many financial interests milking the current system for all its worth.

    Anyway, the real defence is moving to a (software patent) free country.

    The cost of searching for patents whenever you're doing something, anything, really, is a huge burden on any R&D department. By forbidding employees to look at patents, companies make then focus on the important stuff: making things.

      How do you work around the Apple multi-touch patents?

      Start by being specific about which patents you mean. "The Apple multi-touch patents" means nothing. Apple has a great many patents, 28 of which contain the words "multi-touch" in the text. Here's a likely candidate, #7656394, "User interface gestures".

      All five independent claims refer to "proximity images", so the obvious work-around for this patent would be to begin with a system that does not use an image (a regular, contiguous array of pixels in two or more dimensions) as the primary data structure.

      There's more to it than that, but the basic process is the same: be specific as to what patent(s) you are concerned with; read the CLAIMS (not the abstract) carefully and then the supporting material to ensure you understand the terms of art being used.

      This patent doesn't actually define "image", but it is clear from context, and equally clear from common usage that a data structure that contains only a list of (mostly non-contiguous) points of contact is not an "image".

    He answers that in the article, he says we need to make the OSS community the hardest, meanest thing possible to attack with a patent, and he explains a way to do it:

    Every time an open source project gets sued, we need to find a workaround for the patent, and publicize it loudly, so anyone can use that workaround. The great thing is, after that, the suer would no longer be able to collect royalties from anyone for that patent, because they will just use the workaround. Suing the open source community will be equivalent to losing all potential revenue from your patent. No one will want to do it.
