As the transportation industry grows by leaps and bounds, with electric and autonomous vehicles taking center stage and entering a new phase of growth and development, a quiet yet hugely consequential battle is playing out — one defined by patents, protectionism and the pursuit of dominance. At the centre of this battle are two competing innovation models, represented by Tesla and BYD, the most prominent players from two of the world’s biggest economies.
In this article, we will delve into how patents are shaping the future of mobility, what the data tells us about the EV landscape, and why the next phase of the U.S. – China tech war may be fought in the patent offices and courtrooms.
China’s Relentless Innovation
According to the World Intellectual Property Indicators 2023, China filed over 1.6 million patent applications in 2022 – nearly 47% of all global applications. The U.S., in contrast, filed 594,340 applications, comprising just 17.2%. To add to that, reports suggest that more than 62,000 patents related to EV charging technologies originated from China, compared to just 4,306 from the United States. Moreover, China had the highest number of patents in force worldwide in 2022. This is a testament of the massive investment China has been putting in it’s research and development programs. A recent report from the National Bureau of Statistics in China noted that the country’s expenditure on research and experimental development (R&D) rose from 2.4393 trillion yuan ($333.75 billion) in 2020 to 3.6130 trillion yuan ($494.34 billion) in 2024. These sheer numbers signal China’s long-term strategic intent to capture the market for future-critical technologies.
BYD vs. Tesla: A Patent Face-Off
The contrast in patent strategies of leading EV players from the U.S. and China reveals deeper dynamics of their national innovation cultures and how each is positioning itself in the global market.
Tesla holds 3,442 patents worldwide, spread across 1,139 patent families, with 2,551 active patents. BYD, on the other hand, boasts a portfolio of over 20,000 patents, including both international and domestic, making it a clear leader in the race for patent accumulation in the EV sector. But this difference isn’t merely statistical. This reflects two fundamentally different approaches to competition in IP. Tesla’s historic decision to “open-source” its patents in 2014 was seen as visionary by many – a step towards accelerating innovation and adoption of the electric vehicles among the masses. However, in today’s climate of rising trade barriers and tech wars between U.S. and China, Tesla’s open model may turn into a strategic liability in the long run. The rise of new Chinese automakers like NIO, Li Auto, and Xpeng, coupled with aggressive global expansion, may force Tesla to reconsider its open IP strategy and adopt a more protective, closed-innovation approach to defend its market share.
Innovation Concentration and Strategic Depth
China’s edge isn’t just in patent volume, it lies in the strategic integration of IP across key verticals that support the EV technology. As noted earlier, China leads in EV charging patents. But more importantly, BYD’s patent portfolio spans across critical technologies such as fire-safe iron phosphate chemistries (the backbone of their battery technology), energy recovery systems, and advanced EV drive systems. Tesla, while technologically advanced, shows lower patent intensity in certain sub-domains. If patents are to serve as the proxies for future control over the market and licensing revenues, Chinese automotive giants appear better positioned for long-term dominance.
From Factory Floors to Patent Courts
The 102.5% U.S. tariff on Chinese EVs, part of a broader 2025 trade escalation, is pushing Chinese EV makers to accelerate global patent filings, especially in key jurisdictions like the U.S. and Europe. This is evident from multiple reports suggesting that China’s share of U.S. patents has increased from less than 1% in 2010 to nearly 9% in 2024. Furthermore, an article published by IPWatchdog reveals that Chinese companies are now filing hundreds of IPR petitions at the PTAB to invalidate the patent rights of small U.S. businesses that are leaders in sectors.
With patent infringement litigations such as Contemporary Amperex Technology Co., Limited (CATL) vs. China Aviation Lithium Battery Co., Limited (CALB) over EV battery technology, and many more emerging while electric and autonomous vehicles are still in a nascent stage – it is evident that the future holds intense patent wars. In this landscape, litigations, injunctions, and exclusion orders might become strategic tools to assert market dominance. And in such a world, players with deep, geographically diverse patent portfolios may wield asymmetric power over those pursuing leaner, more open IP strategies.
Patents as the New Battleground
As the electric and autonomous vehicle market matures, the fight for dominance is shifting from production capacity to intellectual property control. China, led by BYD and backed by a massive patent ecosystem is steadily consolidating its IP power. Meanwhile, Tesla’s open innovation model, which was once praised for its boldness, may now face a reality check in the global race to the top.
In the coming years, patent filings, licensing deals, and litigation battles may become just as important, if not more, than the next big EV launch. Because in the future of mobility, those who own the patents might just own the road.
