Moon-Lancer said:Other criticism is based around the part of the d20 System Trademark License which defines "Open Game Content" to include game mechanics and purports to license it. It is widely believed that game mechanics are uncopyrightable in the USA, and according to a circular on the US Copyright Office's website [3], "Once a game has been made public, nothing in the copyright law prevents others from developing another game based on similar principles."

http://www.copyright.gov/fls/fl108.html
Copyright protects only the particular manner of an author’s expression in literary, artistic, or musical form. Copyright protection does not extend to any idea, system, method, device, or trademark material involved in the development, merchandising, or playing of a game. Once a game has been made public, nothing in the copyright law prevents others from developing another game based on similar principles.
so that i think gives me a little more fresh air. still i think complying with ogl is the best thing to do, but part of it seems kindof.... un protected by the law. I do realize though my situation is still a gray one.
A fascinating lecture in copyright law but, as my post above mentions, copyright law has nothing to do with the situation. You need to start by understanding the diferences beteen copyright law and contract law. You then need to understand that by using the d20 STL, you are entering into a contract where you agree not to use the specified material. Whether or not that material is copyrighted, trademarked or patented is irrelevant. All that matters is that it is mentioned in the contract which you have agreed to.
