Well, you don't find such clauses in open source licences Perl 6 - second systems done right	[reply]

I think the GPL v3 comes close, or at least forces restrictions on the (distribution of) the output generated by a GPL v3 program. But I have solved this problem for me personally a long time before the GPL v3, so I haven't investigated whether that is really the case for things like a compiler. It seems to be the case for things like web application servers, where accessing the application over the web is basically identical to distribution of the application server binary.	[reply]

The GPL v3 text says The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. and I have no idea what that means. There's an interesting FAQ entry, which contains the sentence If the user uses your program to enter or convert his own data, the copyright on the output belongs to him, not you Which seems to imply that if you write a compiler and license it under the GPLv3, the output still belongs to the user. Comforting. Perl 6 - second systems done right	[reply]

Well, IANAL, but I can't imagine that sort of clause standing up in court in the UK. Despite what makes a good story for the newspapers, UK judges tend to apply common sense, especially in common law, which covers most of contract. They would put such clauses on a par with a saw manufacturer claiming rights over chairs. There is some statute law, but that tends to protect consumers, for example http://www.oft.gov.uk/about-the-oft/legal-powers/legal/unfair-terms/. But other countries will differ.
