DJI, the world’s leading maker of unmanned aerial vehicle (“UAV”) and camera technology, Friday filed a patent infringement lawsuit against Yuneec International Co. Ltd. and Yuneec USA, Inc. in the United States District Court for the Central District of California.

The complaint asserts that Yuneec’s products and technology infringe two DJI patents and seeks injunctive relief to halt the further sale of the infringing Yuneec products and systems.

DJI’s complaint alleges that Yuneec’s UAV products infringe one or more claims of DJI’s U.S. Patent Numbers 9,164,506, titled “Systems and methods for target tracking,” and 9,280,038, titled “Interchangeable Mounting Platform.”

DJI has invested a substantial amount of resources over the course of nearly a decade into the research and development of UAVs.  This investment has generated technology that is fundamental to the future of the UAV and related industrial applications.

DJI welcomes competition, but is committed to protecting its intellectual property. Friday’s filing is a response to safeguard that investment, to protect customers and partners and to promote genuine innovation in this promising area.

DJI holds hundreds of patents worldwide, including at least 30 issued in the U.S. and has at least 50 applications pending there. DJI offers state-of-the-art products and solutions for aerial photography, cinematography, remote tracking and monitoring, geological surveying, and many other commercial, personal, and industrial applications for professionals and hobbyists in the fields of journalism, filmmaking, emergency services, industrial equipment and road monitoring, and many others.

DJI is represented by the law firm of Wilson Sonsini Goodrich & Rosati, P.C.

This is the first time I ever heard the name Yuneec.  Not sure if its the same exact company.  I also think they made a small rc toy coaxial helicopter that looked like a spaceman around the same time as the video. If I am not mistaken, Yuneec has been around for a minute.

Remember DJI's X project video back last November when they claimed new stuff Anyone that has been around for a while knows they joined an OS project then forked it and stopped contributing. The clever, very clever thing they did was wrap the innards in what was at the time the smartest case and then got a high profile American chap to shout about it. He did very well.

That February 2010 video from Mikrokopter you linked to  is a classic. ( DJI's first  multirotor flight controller came out at least 1.5 year later, not to mention  follow-me years later after that.

It's the same old story all over again. Small companies innovate, while large companies protect assets.

@ John. might say steal then protect.

Of course, that was also par for the course for Apple and Microsoft.

Not to forget Xerox PARC where Apple IOS, Windows and even the Mouse actually came from.

It's why open-source is the best defence against patent trolling, IMO John.

Well, whatever happens,  as an experienced hobby-class muticopter and R/C helicopter builder/pilot who at any given time owns a dozen or so of these wonderful aircraft, I'll give up my Yuneec (Blade) Chroma (rebranded/speced by Horizon) and its great Tx and very, very nice 4K camera (CGO3) when DJI's law-bots pry my cold dead fingers from it, as the saying goes. This thing is the ultimate opposite of DIY. I love DIY stuff, but sometimes it's just great to go with something that out of the box functions exactly the same way every time, with zero drama, zero fussing, hassle-free deployment, that flies gracefully and looks nice, and so on. A fabulous machine.

@Todd - I think Yuneec has been building Horizon Hobby (Blade) products for many years - maybe since the start of their foray into mutirotors and maybe even before. They also built electric REAL airplanes. That is one indication of the shallowness of this lawsuit - that whoever wrote it didn't seem to know that or else is trying to fool the judge or the other side? Anyone who has looked at this industry has known Yuneec built stuff for Horizon - and Walkera (cameras) for that matter. Exactly how long is another question, but I suspect it's been many years...certainly not like the suit says that Yuneec got an idea in 2014...
