Patent Threat for Posting Partial Sources to a Weekend Project

Via Hacker News, I came across this chilling account of a patent infringement threat in response to a blog post where a free software/open source developer, Roy van Rijn, speculates about how to put together a Shazam workalike, just out of personal curiosity. Unfortunately, he mentioned Shazam explicitly in the post’s title which may have made it easier for Darren Briggs, CTO of Landmark Digital Services which holds the patents in Shazam, to find and threaten him.

van Rijn fully details his exchanges with Briggs, including the letters he received and the various legal assistance he felt compelled to seek. The conclusion is that the issue is just muddy enough that van Rijn’s best tactic is to refrain from releasing any sources and possibly even removing the mere discussion of a general approach to music finger printing and matching.

Cory at Boing Boing puts his finger right on what is wrong with this scenario.

I don’t know whether van Rijn’s code violates the Landmark patents, or whether Landmark’s patent claims are valid, or whether Landmark holds EU patents as well (it’s not clear from Briggs’s letters whether any of these things are true). But one thing I’m dead certain of is that it is not illegal to discuss a patent’s technical workings. The entire point of the patent system is to give a monopoly to an inventor in exchange for full disclosure of the invention so that other inventors may study and learn from it. In other words, the patent system exists to encourage discussion of patented inventions, not to censor them.

As Cory concludes, the fact that a patent by its nature is publicly available and mere discussions of its contents, coincidental or knowingly, shouldn’t be actionable hasn’t stopped van Rijn’s speech from being chilled,

I get that patent law, at least here in the US, doesn’t consider independent invention an allowable exception so an actual code release might have been actionable. Except van Rijn never made it that far, under an open license or otherwise. Reading through his original blog post, this doesn’t even come across as dedicated reverse engineering. What horrifies me is this is just the kind of spitballing any hacker might do in thinking through a particular class of application, just to get a sense of how it might generally work. I am disturbed that Briggs and Landmark weren’t called to task for this curtailing of free speech and worried at how this may encourage further chilling of sharing and experimentation by independent programmers of all stripes.

    Hello,

    On behalf of the larger internet music community, your CTO is hereby notified to Cease and Desist from sending Cease and Desist letters to people in other countries trying to do good things.

    Your CxOs’ desire to single-handedly control the way music is sampled, reeks of a colonial, imperialist mentality which is completely obsolete and totally incompatible with the internet.

    Your CTO’s emails asking Ron Van Rijn to not release source code are ridiculous at best and disgusting and unconstitutional, anti-freedom-of-speech at worst.

    Please issue a public apology to Ron Van Rijn for harassing a good man, or else, face permanent tough love on the Internet and consequently permanently offline.

    There’s no telling when and where someone on the road will stop and call you names in public.

    If you want to make money, the Internet will give you a 100 new ways every year.

    If you want to make money by threatening innocent people and stifling creative philanthropy, the bad reputation you will earn will remain forever and you will not be trusted by anyone again.

    Your CxOs have invited a Public Relations nightmare upon themselves.

    I hope they have the wisdom to apologise. Here, in Asia, your Intellectual Poverty laws are irrelevant, our Govt is very much sensible, and we continue to not provide a large amount of your revenues despite being populous consumers of all kinds of western music.

    Stop being idiots.
    Start being techies.

    Sincerely,
    Asian internet music lovers.
