Great question, and I'm waiting for an answer from somebody with a legal background. I recently spent a lot of money on "Cue The Magic," and was majorly ticked to find at the very end of the written instructions that TV rights were by permission only, and did not convey with the purchase.
Is this even legal? I have no idea. It was manufactured in India and the rights are kept by a Brit, which complicates things even futher.
My feeling is that if such restrictions are made, it should be included in the advertising. Otherwise, once you purchase an effect, it is yours to do with what you will.
