In the 21st century, the race for power isn’t just about armies, oil, or trade. It’s about ideas and the patents that protect them. On that battlefield, China has pulled off one of the boldest transformations of our time.
In the 1990s, China was still branded as the “world’s factory,” famous for making other people’s products cheaply. Today, it files nearly half of the world’s patents and is home to corporate giants like Huawei, BYD, CATL, Alibaba, and Tencent. But here’s the twist: this was not a rise built only on earth-shattering inventions. Much of it started with junk patents.
Yes, junk. And that junk was exactly what China needed.
The Subsidy Revolution: Filing First, Innovating Later
Around the mid-2000s, China launched an experiment that would change global innovation forever. It rolled out patent subsidies at every level—national, provincial, even municipal. File a patent, get a cash reward. Secure a full invention patent, get even more. File internationally under the Patent Cooperation Treaty (PCT), and the payouts multiplied. Filing fees were slashed, tax breaks dangled.
It was like turning patents into lottery tickets—cheap to buy, potentially rewarding, and available to everyone. Students, small businesses, hobby inventors, universities, and giant corporates all jumped into the game. The idea was simple: reward anyone willing to file, and the culture of innovation would follow.
The result was explosive:
2011: ~526,000 invention patent applications.
2020: 1.5 million.
2023: 1.68 million—46% of the world’s filings.
WIPO data shows invention patent applications jumping from 526,000 in 2011 to over 1.5 million in 2020, and 1.68 million in 2023, accounting for 46% of global filings.

On paper, China became the world’s top patent filer. In practice, many of those patents were never used, never licensed, never commercialized. Critics mocked them as junk patents.
The Quality Question — How Many Patents Really Matter?
Filing a patent is one thing. Turning that patent into something useful is another. In theory, the patent system is built to reward only ideas that are new, inventive, and industrially applicable. In practice, though, the bar isn’t always as high as it sounds.
In countries where filing is cheap and incentives are strong, you often see patents granted for things that are technically new but not groundbreaking. Some patents are filed mainly to stake a claim in a market space or to block others, rather than to develop the idea. In the United States, for example, the “continuation” process lets applicants keep filing slightly modified versions of the same invention. That can be a smart strategy, but it also means portfolios grow without necessarily adding much real innovation.
Even in places with tougher rules, like the European Patent Office, speculative patents still get through, especially in fast-moving fields like AI, quantum tech, and biotech, where the technology may not be fully proven yet. The same happens in Japan and South Korea, where filing support is generous and patents are seen as valuable R&D assets, whether or not they’re ever used.
Researchers who study this issue estimate that only about 5–10% of all patents worldwide end up becoming commercially important. Many are never licensed, never built into a product, and never generate revenue. That’s why some experts warn that piling up low-value patents can actually slow innovation: it clutters the system, makes it harder for real inventors to find a clear path forward, and increases the risk of costly legal fights.
But here’s the thing, junk has value.
Why Junk Patents Matter: Culture and Breadcrumbs
Think of junk patents as the training wheels of innovation. Training wheels don’t win you bike races but without them, millions would never learn to ride in the first place.
1. Building a Patent Culture
Before subsidies, patents were something only large corporations cared about. After subsidies, filing became second nature like brushing your teeth or checking your phone. Everyone filed: engineers, professors, students, even tiny startups.
This created a patent culture: a mindset that ideas aren’t just for the lab, they’re assets, weapons, bargaining chips. Just like fitness apps gamify exercise with points and badges, subsidies gamified innovation. Filing became a habit, and habits build ecosystems.
2. Leaving R&D Breadcrumbs
Even unused patents leave something behind: knowledge. Every patent must be published with technical details. These act like breadcrumbs on the innovation trail.
Imagine a dense forest where inventors are searching for new paths. Every patent, even a dead-end one, leaves a marker: “Don’t go here, already tried.” Later explorers can follow these markers, avoid wasted effort, or even rediscover abandoned paths with better tools.
History proves this works. In aviation, countless “failed” designs from the 1900s are preserved in patent archives. Decades later, engineers revisited some of those concepts with new materials and computing power, making them viable. Today’s drones owe much to yesterday’s forgotten sketches.
China’s junk patents served the same role: thousands of breadcrumbs scattered across sectors, waiting to be picked up when technology or markets caught up.
3. Strengthening Corporate Muscles
Managing patents is like going to the gym. Filing, defending, licensing all of it strengthens corporate IP muscles. Subsidies forced Chinese firms to bulk up fast.
Huawei learned to dominate telecom standards by filing aggressively. BYD and CATL became EV battery kings with mountains of filings in chemistry and architecture. Alibaba and Tencent turned software, fintech, and gaming ideas into global portfolios.
The junk era was their bootcamp. Today, these companies wield patents not just for protection but as bargaining chips in cross-licensing, weapons in litigation, and leverage in trade negotiations.
The Pivot: From Quantity to Quality
Of course, training wheels must eventually come off. By 2020, the downsides of the numbers game were obvious. Many filings went unpaid after subsidies were claimed. Some provinces saw entire spikes of patents that were abandoned within a year.
In 2021, the China National Intellectual Property Administration (CNIPA) announced it would phase out all patent subsidies by 2025. The new goal: “high-value patents.” That means patents tied to real commercialization, real industrial use, and real impact.
This wasn’t a retreat. It was a pivot from sheer volume to targeted strength.
Corporate Champions: Proof of the Model
The transition is already visible in China’s corporate giants:
Huawei: 110,000+ active patents, global leader in 5G SEPs, spending 15%+ of revenue on R&D.
CATL: 31,000+ patents in EV batteries, supplying Tesla, BMW, VW.
BYD: Expanding rapidly in EV tech and energy storage.
Alibaba & Tencent: Thousands of patents across AI, fintech, logistics, and blockchain.
These are not “junk” anymore. They are weapons, assets, and the backbone of China’s global innovation push.
Conclusion: From Junk to Genius
China’s innovation journey shows that sometimes, quantity is the path to quality. Subsidies turned filing into a national habit, junk patents seeded an ecosystem, and the sheer bulk built corporate IP champions.
Now, with subsidies ending and commercialization rising, the mountain of paper is becoming a true power.
The lesson? Innovation leadership is not about waiting for perfect ideas to appear. It’s about creating a system where everyone files, everyone plays, and then refining the mass into gems.
Just as compost turns waste into fertile soil, China’s so-called junk patents have enriched its innovation landscape. And today, the harvest is global supremacy in intellectual property.
