DJI successfully countered "patent hooligans", and the invalidation of patents was its weapon.

According to NetEase Science and Technology Daily, recently, Shenzhen DJI Innovation Technology Co., Ltd. (hereinafter referred to as "DJI") has made new progress in the patent dispute that has lasted for more than two years in the United States. DJI Synergy the plaintiff Droneof 5All the patents involved were successfully invalid. In March 2017, Synergy Drone sued Dajiang for infringing the patent rights of five of its patents in the Texas court, Synergy Drone claimed that the "headless mode" used by Dajiang's UAV products infringed the patent rights of the patents involved. Headless mode refers to the aircraft in the process of flight, its movement around the geographic coordinate system as the reference coordinate system. Headless mode is mostly used in multi-rotor, such as four-axis, six-axis aircraft, the technology is currently a common means in the field of drones, in the case of patent applications before there have been relevant patents and public documents. In the course of the lawsuit, DJI filed an invalidation of the patent involved. Synergy Drone filed 76 claims when he filed the lawsuit, and in the process of DJI filing the patent invalidation application, he revised and increased the claims to 142 to deal with the possible adverse consequences of the invalidation procedure. However, after the review by the US Patent Trial and Appeal Board, it was found that all the claims of the five patents involved were invalid, which made DJI in a favorable position in the above patent disputes.

It is understood that the plaintiff Synergy DroneDoes not produce any drone products, DJI's attorney said that this is likely to be a "patent hooligan", and this patent dispute is not the first time DJI has confronted a "patent hooligan. 2017In December 1993, the official website of the Patent Reexamination Board of the former State Intellectual Property Office showed that many utility model patents owned by Gaoyu (Beijing) Intelligent Science and Technology Research Institute Co., Ltd. (hereinafter referred to as "Gaoyu") were successfully invalidated by DJI. Gaoyu is a company without any products and research and development. According to the records of the State Intellectual Property Office, Gaoyu has launched a large number of patent infringement lawsuits against domestic UAV manufacturers, including DJI, in many courts across the country. The prosecution places include Beijing, Shenzhen, Nanjing, Shanghai and other places. Domestic manufacturers such as DJI also use patent invalidation procedures to launch counterattacks.

Innovative entities are often passive in dealing with the entanglement of patent hooligans, and patent hooligans rely on litigation to profit in many countries, including the United States and China, which do not violate the relevant provisions of patent law, but take advantage of loopholes in patent protection law. United States Patent Organization Unified PatentsThe latest report released shows that 2018In the third quarter of 2009, 85% of the 1901 high-tech patent litigation cases in the United States were initiated by patent hooligans. DJI's successful counterattack against "patent hooligans" shows that Chinese enterprises are gradually familiar with the rules of patent disputes and have mature countermeasures. This is due to the continuous improvement of corporate intellectual property awareness, intellectual property construction is becoming stronger and stronger, and it can be in a leading position in many fields.
