An Indian drone company has alleged copyright infringement of its autopilot technology by Chinese entities and has asked the government to crack down on imports to protect its intellectual property rights. Chennai-based Zuppa Geo Navigation Technology has written to Directorate General of Foreign Trade (DGFT), seeking a ban on imports from Chinese companies that, it alleges, have infringed on its patent. In a representation to DGFT, the Indian company has said it was awarded a patent in April this year for a real-time computing architecture called 'system of disseminated parallel control computing in real time'. The patent was granted after a nine-year scrutiny, the company said. The company has petitioned that a Shanghai-based company, JIYI Robot, has been exporting autopilots to India that directly violate this intellectual property rights. Another company named CUAV based out of China too is supplying autopilots that allegedly infringe on its copyright, Zuppa Geo said.
