Global Comparison of Patent Policies in the Aerospace Sector: United States, Europe, and China

During 2024, patent activity in the aerospace, defense, and security sectors declined, according to Army Technology. Data from GlobalData indicate that, in the third quarter of 2024, global patent filings decreased by 25% compared to the previous quarter.

The United States led this activity, accounting for 26% of total filings, closely followed by China at 24%. This U.S. leadership may be partly due to domestic government policies.

According to Space Insider, the United States takes a more market-driven approach to aerospace patents. A study published in January 2025 in Economics and Management Innovation highlights how U.S. patent policy supports commercial space enterprises through open market access, technology transfer, and government contracts. Since the early 2000s, this strategy has encouraged private sector involvement in space.

As a result, the U.S. approach appears to be more effective in encouraging patent filings than those adopted by other countries, such as European nations and China.

The cited study notes that Europe favors long-term policy frameworks and international cooperation. However, despite incentives offered by various European countries, regulatory complexity and a decentralized approach make it less effective in promoting patent filings compared to the United States.

China, on the other hand, has taken a different path. The Chinese government supports the aerospace sector through subsidies, tax breaks, and state-led initiatives. Companies filing patents can benefit, for example, from a 25% corporate tax reduction. However, most patent filings by Chinese companies remain domestic, mainly due to cost considerations. As a result, while the volume of patents in China is high, long-term protection and international competitiveness are still developing.

In summary, as Space Insider points out, as commercial space activity accelerates, the ability to protect and leverage intellectual property will become increasingly critical. Companies operating internationally will need to navigate these diverse patent landscapes to secure market position and long-term growth.

Conclusion

The landscape of patent policies in the aerospace sector reflects broader economic and strategic priorities of the United States, Europe, and China. While the U.S. model fosters innovation through market-driven incentives and strong private sector involvement, Europe’s collaborative but complex framework and China’s state-led approach each present unique advantages and challenges. As the global aerospace industry continues to evolve, companies and policymakers must adapt to these differing systems to maximize innovation, protect intellectual property, and maintain a competitive edge in an increasingly interconnected market.
