Germany-based eVTOL developer Lilium has filed 37 new patent applications that have been published by the European Patent Office (EPO).

These are engineering inventions for the core technology around the Lilium Jet, spanning several domains including energy, propulsion, structures and interior, avionics and custom electric. Lilium is focusing more than 70 per cent of its patents on energy and propulsion.

These patents are part of a batch of 50 patents the company filed throughout 2021, with more to come in the next year. Applications with the EPO will, if accepted, secure Lilium's intellectual property in Europe, and Lilium is also extending patents in other key markets, including the US and China, in order to protect its inventions.

Co-founder and CEO Daniel Wiegand says: “We are excited that Lilium is creating and protecting the radical engineering innovations that make the Lilium Jet unique. The applications published today serve as a testament to our engineers' ingenuity and commitment to pushing the limits of technology and reinforcing Lilium's place at the forefront of eVTOL development. These patent filings move us one step closer to commercialisation of the Lilium Jet, but they also stand to strengthen innovation in the aviation industry as a whole, with areas like energy needing constant investment in novel and sustainable systems and technologies.”
