Puntomaus, you could do exactly that.

There is no way anyone could copyright a pose set, a light set, or a character morph that has been made just by spinning the default morph dials.

The creator only holds the copyright of the SET, i.e. the "packaging" that goes along with it, like the wording of the ReadMe and promotional pictures, but not the actual raw data of the poses.

A sitting pose is a sitting pose is a sitting pose.
There is no way a judge could positevely decide which of two identical sitting poses is the "original" and which one is the "copy".

It wouldnt be "nice" to sell someone elses pose set, but it would be perfectly legal.

Think of it like this: You can own the copyright of a story, but you cant own a copyright of the words the story was made of.

And in Poser; poses, lights, and morphs are the "words" that create the "story", the final Render.
