Love these discussions and how they always turn up. Same basic question, same basic answer.
Q: Can I (insert your copyright/trademark/patent here).
A: Don’t come here for legal advice. Research it and/or seek the advice of an attorney who specializes in this. Can’t afford one? There is the library, gov. websites for copyright and trademark that have correct legal information. Some lawyers will also post some information on their websites for free.
I think threads like this should be closed locked or just deleted whenever they pop up. And there should be a sticky:
Don’t post threads that ask for legal advice.
They should be disallowed altogether.
This is the last place to get reliable information on anything frankly (outside of the Blender support forms), much less legal advice.
