(By You Yunting) Recently, a lawsuit filed by Chinese drone giant DJI against its rival Insta360 has drawn attention from both the tech and legal communities. The core dispute is straightforward: several engineers who had left DJI for Insta360 filed multiple drone-related patent applications within one year of their resignation. While the inventors’ names were kept anonymous in domestic patent filings, subsequent disclosures under the Patent Cooperation Treaty (PCT) revealed that all the patents were invented by those former DJI employees. DJI has since sued Insta360, seeking for the corresponding patent rights to be transferred to itself.
