SGT (Join to see) - Copyleft is hazardous to entrepreneurial code developers seeking to market a commercial product with the level of support appropriate for non coding and non developer users. Take a look at MIT / BSD / UC Regents public use licenses for a far better and less risky alternative. The IBM DX Data Explorer source code was released under MIT / BSD / UC Regents license resulting in many derivative products. Warmest Regards, Sandy :)

1LT Sandy Annala Ma'am, that is an interesting view. Thank you for that point. Let me make sure I understand what you are saying. Copyleft looks to be a less restrictive system for the end user and does not give the developer control over their code. By using copyleft, their code is open to be used in a ways that maybe detrimental for their company. Such as their code being used to create a new patent. Whereas the MIT and BSD license does not allow for the creation of new patents. This gives the developers more control over how their software is used without restricting derivative works.

SSgt Mark Lines - You should very carefully review Chapters 2 and 3 below. The real issue has absolutely nothing to do with patents . . . everything to do with copyright and your obligations as creator of a derivative work under MIT, BSD, and GPL copyright legends. You must watch very carefully the definition of a derivative work . . . e.g. whether dynamic or static linking of GPL'ed GUI, Network, or other libraries makes your work a GPL'ed work. The effect of the two major forms of license are the opposite of what you describe above . . . GPL'ed code is encumbered with many restrictions and obligations . . . non-GPL'ed code is free from most of those restrictions and obligations . . . i.e. other than endorsement/naming restrictions. Non GPL'ed code is critical to the future of free software development in a way GPL'ed code (copyleft) may never be used. Warmest Regards, Sandy :)
