What is the Best Way to Handle a GPL Violation?
DeadSea queries: "When you find that somebody is violating the GPL by distributing your code or a derivative of your code as a closed source product, how do you go about handling it? I have found two violations of the GPL for my Java Utilities, in the last month. The Free Software Foundation says that the copyright holder is the only person empowered to act. If you are the copyright holder, how do you communicate with the offenders? I know folks here must have dealt with this before: Linksys, SCO, Castle Technology, United Linux, and others. Personally, I would like to believe that with a little nudging (and without lawyers), I can resolve the things. As such, I would especially appreciate any example letters or other documents that might be effective."
I would suggest sending an informal e-mail asking if they understand that they're violating the GPL. If that doesn't resolve the problem, the next step might be e-mailing someone at the FSF for advice. If you really serious about it and the FSF can't help you, you may need to get some advice from a lawyer.
Of course, the Passive Aggressive way would be to simply decompile the byte code. Java decompilers are quite excellent at producing almost exactly the same source code as was there to begin with (minus comments). You could then put the GPL license at the top, post a copyright for the work they did. After that, send them a letter telling them that you assisted their efforts at becoming compliant with the GPL. You could even bill them with a consulting fee if you really wanted to get a funny reaction from them. Of course, if you did this, you would almost certainly need to find a good lawyer ahead of time.

Shoot on site!!
And we'll, uh... check out their websites... until they stop responding. That'll get their attention.
Get a lawyer. Asking for legal help on slashdot is about as dumb as asking us for medical advice. (It's possible that the advice might be good, but you could end up neutering yourself)
In 1991, a crack development unit was sent to prison by a software patent court for a crime they didn't commit. These men promptly escaped from a maximum security stockade to the Linux Expo underground. Today, still wanted by the government, they survive as coders of fortune. If someone rips off your code, if no one else can help, and if you can find them, maybe you can hire... the C-Team.
