A copyright doesn't keep people from putting out the trick. They just cannot copy the instructions word for word. If they rewrite the instructions, they can put out the same trick legally (not ethically, but legally). To keep them from putting out the same trick, you'd need a patent. A couple of problems with that. One is that it is very expensive--costs more than you're ever likely to make marketing most magic tricks (except for expensive illusions, etc). Second, you have to reveal the workings of the trick, which then are open to the public--exposing the mthod, and making it easy for someone to modify slightly and make the same trick. Not really worth the trouble, is it?
Regarding this version of the flying cards: My favorite version of Princess Trick is Larry Jennings' Limited Edition. One packet of 5 cards, they think of one and then one card becaomes blank--the one they thought of!
For Cards Across on the other hand (and this trick is basically a combination of Cards Across and The Princess), I prefer versions like Tamariz' or Aronson's Red Sea Passover. In these routines, there are two packets of twn cards. Spec decides on, say, two cards from one packet. That packet is counted and there are only eight cards and the selections are not among them. The other packet is counted--TWELVE cards, with the selections now there. In the Aronson method, the packets are different colors, so at the end, you spread the blue-backed packet to find the red-backed choice!
IMO, this is stronger, because the cards "actually" vanish from one packet (now only eight cards) to appear in the other (now really 12 cards). When the same number of cards remain in each packet, the effect is not as clear nor, IMO as strong. And in Simon's version, when that blue packet is spread and a different colored card is exposed...!
Just food for thought.
