Singer Katy Perry’s performance at the Super Bowl in America a year ago had a legal repercussion. The singer appeared onstage with two dancers in shark costumes, and the one on the left hopped about somewhat clumsily. “Left Shark,” as the dancer was subsequently known on the Internet, became famous overnight.
An entrepreneur wanted to make money out of that notoriety and decided to sell models of the shark on the 3D-printing platform Shapeways. Soon thereafter, he received a letter from Ms. Perry’s lawyers: They sent a cease-and-desist order, asserting copyright infringement.
It was one of the first times an act arising from use of a 3D printer led to legal proceedings. In Germany, no verdicts have yet been issued in connection with the technology. But the more it is used, the more legal disputes can be expected.
