J5 and I had this conversation about CdN as I was curious about it as well. Technically speaking (not a lawyer here) I do believe he has the rights to it. I do not agree completely with this and think the rights should be shared (i.e. law should be changed). For example, the concept of CdN was mine and he made it happen. There is intellectual property on both sides I think. J5 has been very gracious and professional about the rights and he does not share contracted designs without the contracting user's approval. He also allows complete rights to be purchased for a reasonable amount. Furthermore, to make matters more complicated, sometimes artist and client are different countries making for legal shenanigans.
