Technically, if a Product has Licensing (and the words are Trademarked, the designs are copyrighted. You can License both), it has to include the Licensing Statement acknowledging the ownership of the Trademark and Copyright. 

This Licensing agreement also could include restrictive use. I worked on a deal where, if it is completed, the Licensing for the product would have include a statement saying no use of Nudity in the Render with product or images of illegal acts, acts of a sexual nature, etc.... (Long List). The hanging point was they wanted a Licensing Statement to be included in the Packaging of any Final Work IE Renders/Animations. Wording the License in a matter that allows someone buying a Mesh to have distribution Licensing of their images was what ended up killing the deal. My Lawyer wanted a few grand and they wanted us to also pay for their Legal Department to review the Agreement and amend the Agreement.. there was not that much money in the first few products planned! We also figured it would add about $20 onto each product just to cover the legal expenses!

I might try it again if I had more products lined up to make back the initial cost.
