In 2026, China’s patent system continues to evolve, emphasizing quality, enforceability, and
strategic commercialization. Governed by the Patent Law of the People’s Republic of China
(latest amendment 2021) and administered by the China National Intellectual Property
Administration (CNIPA), the framework now increasingly supports not only filing and
prosecution but also high-stakes enforcement and licensing strategies. A practical example
illustrates how a well-structured patent portfolio can protect innovation, generate revenue, and
maintain competitive advantage.
DJI, a leading global drone manufacturer, has consistently focused on protecting its core
technologies in unmanned aerial systems, including drone propeller designs. In 2023, DJI
faced several local competitors in China producing imitation drone propellers that infringed
on its utility and design patents. DJI had previously registered its patents with CNIPA, including
a utility model covering the aerodynamic structure of the propeller blades and a design patent
protecting the propeller shape.
When unauthorized manufacturers began selling imitation components online and through
local distributors, DJI employed a multi-channel enforcement strategy. First, administrative actions
were initiated with CNIPA and relevant local intellectual property offices. These actions
leveraged the strong evidentiary value of previously registered patents, resulting in rapid
takedown notices and seizure of infringing inventory. DJI simultaneously filed civil litigation in a
specialized IP court in Shenzhen, seeking injunctions and damages. Within months, the court
ruled in DJI’s favor, awarding both injunctive relief and substantial compensation, reinforcing the
value of proactive patent registration and robust portfolio management.
The DJI case highlights several key considerations for innovators in China. Companies must
focus on the strategic alignment of patent filings with high-value technologies and potential
enforcement scenarios. Utility model patents, while quicker to obtain, provided DJI with immediate
leverage for preliminary administrative actions, while invention and design patents enabled
long-term protection and stronger litigation outcomes. Furthermore, comprehensive
documentation, precise claim drafting, and careful portfolio monitoring allowed DJI to respond
quickly to infringement, minimizing market disruption and safeguarding revenue streams.
For international companies entering China, several strategies are essential: ensuring patents are
filed in China before public disclosure to avoid invalidation risks, combining utility models and
invention patents for layered protection, and actively monitoring CNIPA databases to detect
competitor filings. Engaging local IP counsel is crucial for navigating administrative procedures,
pursuing civil litigation, and executing cross-border enforcement where necessary. Companies
should also explore licensing opportunities to monetize patents strategically, taking
advantage of China’s evolving patent commercialization ecosystem.
China’s patent landscape in 2026 demonstrates a balance between rapid protection, enforceability,
and commercialization. Case studies such as DJI’s propeller patent enforcement underscore the
importance of a strategic, well-managed patent portfolio. By combining careful claim drafting,
proactive enforcement, and adaptive commercialization strategies, innovators can protect their
high-value technologies, assert market leadership, and leverage intellectual property as a tangible
business asset.
