But the text is an embodiment of the expression of the game... and the
expression is what copyright law protects. The operative question is whether
d20 is a pure idea (and thus only protectable under patent law) or
idea/expression, which means it can be covered under both. I'm really
uncertain about that... But if it's idea/expression, then using d20 as a
reference to create compatible rules violates the copyright in the

Well, the industry is very much of the opinion that it is copyrightable... so
absent case law or clear statutory language to the contrary, I'm having a
tough time believing they are not copyrightable. In these instances,
industry custom carries a lot of weight.

But a math formula is not original expression, nor is it an original idea
(which is why it's not protectable under patent law either). As for recipes,
yes, they are copyrighted. The copyright cannot prevent you from using the
recipes to prepare delicious foods... but you are not permitted under
copyright law to write down someone else's recipe and share it with someone
else. Of course, recipes are strange because most food has been around since
the dawn of time, so the public domain is so thoroughly infused with recipes
that it's near impossible to distinguish original expression from PD
As a broader point... the line that distinguishes ideas from expression (and
thus copyright law from patent law) is anything but clear. The two are very
interwoven, and although there is a RIGHT answer (in the sense that the law
should mean one, and only one, thing), the chances that the courts will
settle on a single meaning is unlikely.
