Drone Industry Patent Landscape Is More Global Than Commonly Assumed

China's Volume vs. U.S. Quality

A LexisNexis Intellectual Property Solutions study reveals that China held 44% of global drone patent families by 2024, while the U.S. accounted for 17%. Yet when portfolio size is adjusted for technological value and geographic reach using the Patent Asset Index, the two nations are now roughly equal in total global patent asset value. The U.S. led a decade ago, China surged ahead between 2015 and 2017, but the quality gap has narrowed markedly since 2018.

Startup Innovation Spreads Across Six Nations

Looking at private drone startups founded in the last 15 years, LexisNexis identified a top 10 spanning six countries. The U.S. has four entries (Skydio, Valqari, Anduril, Zipline), China two (Autel Robotics at number one, Zero Zero Robotics), with Japan's Aeronext, Israel's Tevel, Switzerland's Flyability and Sweden's AirForestry rounding out the list. Their focus areas include defense, logistics, agriculture, industrial inspection and forestry, rather than consumer camera drones.

DJI's Patent Dominance Erodes

DJI, excluded from the startup ranking due to the 15-year cutoff, commanded about 24% of the industry's total Patent Asset Index at the end of 2018—more than the rest of the top 10 combined. LexisNexis now estimates its share at just 4%, with annual drone-related filings dropping to three in 2024, a 99% decline from peak. The firm does not pinpoint a cause, suggesting possible factors such as U.S. restrictions, portfolio trimming or a pivot to trade secrets.

Policy Shifts and a Broader Ecosystem

These findings emerge as U.S. policy seeks to lessen dependence on foreign-made drones and components, including FCC restrictions on new models added to its Covered List. Patent activity does not directly translate into market share or manufacturing capacity, and the data reveals no single heir to the dominant manufacturer. Instead, it depicts a less concentrated intellectual property landscape and a more global, specialized ecosystem.
