China Dominates Global Growth in Counter-Drone Patents Amid Rising Security Concerns

Global Investment in Counter-Drone Technology Increases

Rising Patent Activity Indicates Growing Focus

Investment in counter-drone technology is on the rise, as recent data reveals a significant increase in patent applications related to small unmanned aircraft. Research from intellectual property law firm Mathys & Squire shows that global patent applications for anti-drone technologies surged by 27% in the year ending March 31, 2025, with a total of 126 applications filed, up from 99 the previous year.

China led the way with 82 applications, followed by the United States with 22, and South Korea in third place. This trend underscores a heightened emphasis on systems designed to detect, disrupt, or disable drones.

Drone Threats Prompt Demand for Innovative Solutions

Military and Civilian Applications

The increase in patent activity coincides with the expanding role of drones in both military and civilian contexts. In Ukraine, small drones have become integral to battlefield operations, altering how airspace threats are managed due to their low cost and accessibility. Security planners are now seeking more efficient methods to counter these threats.

Moreover, unauthorized drone incidents have disrupted civilian infrastructure, with European airports experiencing temporary shutdowns due to drone sightings. This has highlighted the vulnerabilities of critical transport hubs, including major airports like Munich.

As a result, there is a growing demand for counter-drone systems capable of rapid response and scalability.

Shift Toward Electronic and Directed-Energy Solutions

Innovations in Counter-Drone Technology

The patent data indicates a shift away from traditional interception methods toward electronic and directed-energy solutions. Signal interference and jamming technologies accounted for the largest share of new filings, with 49 patents aimed at disrupting communication links between drones and their operators or interfering with navigation signals.

Laser-related inventions reached 39 patents, while microwave systems accounted for 24. These directed-energy technologies are designed to disable drones without physical impact, reflecting a broader industry trend toward more cost-effective solutions that can engage multiple targets.

Companies such as Epirus are developing high-power microwave systems intended to counter drone swarms, demonstrating the transition of these concepts from research to practical applications.

China’s Dominance in Patent Filings

Research and Development Insights

China’s substantial lead in patent filings highlights its significant investment in counter-drone technologies, with 82 of the 126 applications filed during the studied period. However, it is important to note that patent filings represent research and development efforts and do not necessarily correlate with deployed systems or market share. Some counter-drone technologies, particularly those associated with defense programs, may not be publicly patented.

Companies such as Dedrone, Anduril Industries, and DroneShield are actively deploying counter-drone solutions in commercial and government markets, particularly in the United States and allied nations.

Expanding Use Cases Beyond Military Applications

Emerging Sectors for Counter-Drone Solutions

The demand for counter-drone solutions is increasingly extending beyond military applications. Systems are being developed for various sectors, including:

• Airports
• Energy infrastructure
• Ports
• Prisons
• Large public events

These environments require reliable and scalable methods to detect and mitigate drone activity without disrupting surrounding operations. The growing number of patent filings reflects this shift toward commercial and infrastructure protection use cases.

Evolving Regulatory and Deployment Landscape

Changes in U.S. Legal Framework

In the United States, the legal framework governing counter-drone operations is evolving in response to increasing security demands. Historically, only a limited number of federal agencies, including the U.S. Department of Homeland Security, U.S. Department of Justice, and U.S. Department of Defense, had clear authority to detect and mitigate drone threats.

This framework began to change with the passage of the Safer Skies Act, which expands counter-UAS authority beyond federal agencies to include state, local, tribal, and territorial law enforcement, provided they receive appropriate training and certification.

Additionally, the Federal Bureau of Investigation is enhancing its role by training state and local law enforcement personnel through counter-UAS training programs, prioritizing regions that will host major events, such as the 2026 FIFA World Cup. These initiatives aim to address long-standing capability gaps where local agencies lacked the legal authority or technical training to respond to drone threats.

Overall, new legislation and expanded training programs indicate a shift toward a more distributed counter-UAS model in the United States, with shared responsibilities across federal and local levels.

A Global Race in Counter-Drone Technology

Implications for Airspace Security

The increase in patent filings signals a broader shift in how governments and industries are addressing airspace security. According to Andrew White, Partner at Mathys & Squire, “Drones have shifted from being a niche concern to a mainstream security challenge, and the rise in patent filings reflects that change.”

He noted that laser and microwave systems are gaining traction in the counter-drone market, suggesting that this is likely just the beginning of a broader transformation in how airspace threats are managed.

The data indicates that counter-drone technology is entering a new phase characterized by accelerated innovation, expanding use cases, and a movement toward more scalable and cost-effective solutions.
