Fluffeh writes: "Teller, the silent half of the well-known magic duo Penn and Teller, has sued a rival magician for copying one of his most famous illusions. The case promises to test the boundaries of copyright law as it applies to magic tricks. A Dutch magician with the stage name Gerard Bakardy (real name: Gerard Dogge) saw Teller perform the trick in Las Vegas and developed his own version — then started selling a kit — including a fake rose, instructions, and a DVD — for about $3,000. Teller had Bakardy's video removed with a DMCA takedown notice, then called Bakardy to demand that the magician stop using his routine. Teller offered to buy Bakardy out, but they were unable to agree on a price. So Teller sued Bakardy last week in a Nevada federal court."
