Are equations of state subject to patent rights?

Are equations of state subject to patent rights?

Are equations of state subject to patent rights?

(OP)
Hello,

I was wondering if someone would have a specific knowledge on this:

When someone makes its own implementation/coding of an equation of state (EOS) described in standards (e.g. AGA8 or GERG2008 described in ISO20765) is it legal? can there be patent rights associated with such EOS? I know sometimes these are sold as third party DLL's.
Can this implementation be used for commercial purpose or is it required to pay royalties?

Thanks

RE: Are equations of state subject to patent rights?

my understanding is that if you code yourself the whole procedure (starting from Helmholtz equation, including your own derivatives and solvers etc.) you are not required to pay royalties,
you only need the constants which are available in published standards...
a different story if you include, for example, some lines of code developed by others, in that case I suspect you should pay royaltes, except maybe the case of open source released under some general public license.

Thanks Paolo for your response.

What prompted my question is that in ISO20765 for example, it is indicated that the standard may include elements subject to patent rights. So I was wondering what could that be.

But then if one codes the whole procedure by himself, can the equation of state be labeled as ISO-20765 or GERG-2008?
Are there trademarks...I suspect no, but just wondering?

Thanks again
