Quote - Transfer of software licenses is an issue the courts will need to resolve, as copyrighted physical materials are covered by the Doctrine of First Sale ...

Actually, most license agreements for software and data sets (and that's really what you're buying with a Poser figure, is a set of data files) do not grant ownership of the materials. They grant a license to use the data or software. Ownership actually remains with the original seller.

I haven't read the license agreements from DAZ all the way through (really, who does?) but you might check through them once, just for fun.

Legally, buying intellectual property is typically handled much differently from purchasing real property, be it a car or a box of Corn Flakes.
