"There remains a need for new technologies for generating aerial displays such as a display involving projection of light and images into or out of the sky or an air space above an audience of spectators," the application for another patent reads.
According to MarketWatch, the three California-based men who applied for the patents - Clifford Wong, James Alexander Stark and Robert Scott Trowbridge - are all part of Disney's Imagineering team, the design and development branch behind the elaborate attractions at Disney's theme parks.
Though drones have long been associated with military and surveillance activities, cheaper technologies have paved the way for commercial and even scientific uses of UAVs - to film movie scenes, to conduct archaeological field surveys and to deliver packages (as Amazon is hoping to do with its Prime Air program).
But before the industry can really take flight, the Federal Aviation Administration has to finalize regulations for commercial drone use. The agency hopes to do so by 2015, but in the meantime, commercial drones aren't legally allowed to leave ground. So far, the FAA has only given one company approval to conduct private UAV flights: In June, the agency granted a license to AeroVironment to fly its drones over an oil field in northern Alaska to perform surveys for the energy company BP.
