One of the more interesting cases I came across was: JpGraph Professional Version If you plan on using JpGraph in a commercial context you will need to acquire the professional license. Commercial use is for example if you use JpGraph on a site to provide a service for paying customers or for example if you are using JpGraph in an intranet to provide support for internal business processes, i.e. in benefit for a commercial company.
In short, if you use JpGraph where you have an economic advantage (either through paying customers or improving internal business processes) this most likely falls under commercial use. otherwise: Software License JpGraph is released under a dual license. QPL 1.0 (Qt Free Licensee) For non-commercial, open-source or educational use and JpGraph Professional License for commercial use. The professional version also includes additional features and support. The trouble is that these terms are non-recursive; if I receive JpGraph via the QPL [http://qt.nokia.com/doc/4.0/qpl.html] from someone other than Mr JpGraph, then I receive the rights that the QPL grants, which the conveyor was granted by not using it commercially. Having received those rights, I can now use the software commercially, without paying for a commercial license (and perhaps may not even realise this expectation!). I explained this to the author, who wasn't very interested.
