And I think everyone agrees that if one profits off your hard work, you deserve some compensation. In this case, they always come to us for proprietary licensing, which comes at a fee. Of course, commercial institutions will never want to do this. In that case, the liberal exception does not apply, and the GPL will cover everything the ChemDoodle Web Components is integrated with, including proprietary products and Jmol. The only case where licensing would become an issue is for commercial use of the ChemDoodle Web Components. The only request I have is that users acknowledge that they use the ChemDoodle Web Components. So for academics, the ChemDoodle Web Components can be used with Jmol without any issues. The liberal exception states that in the case of non-commercial use (such as academic) the GPL license will not extend past the ChemDoodle Web Components code.

The GPL v3 license states that anything the software is integrated with must also be released under GPL. The ChemDoodle Web Components are distributed under the GPL v3 license with a liberal exception:

Since ChemDoodle has a different license, some explanation is advisable (following text provided by Kevin Theisen, from iChemLabs, LLC, the makers of ChemDoodle):ĬhemDoodle Web Components licensing is very compatible with Jmol. This new library (Jmol ChemDoodle extension) allows to offer rendering formats alternative to Jmol, using the independent ChemDoodle Web Components software, that does not use Java applets, but HTML5 and/or WebGL technologies to display in devices like tablets and smartphones. Note: Support for integration of the Jmol ChemDoodle extension has been abandoned.
