Patent examination is one of the most dynamic parts of the IP world, where a patent is either approved or rejected based on strict rules, and countries constantly update their systems to make the process more efficient and effective. China is doing the same, with major changes to its China Patent Examination Guidelines 2026 coming into effect on January 1, 2026, especially affecting fast-growing fields like AI, big data, and digital media. Continue reading to understand the implications of these changes, their impact on the system, and stay informed with the latest IP news from India and around the world.
What Are the Major Changes in the China Patent Examination Guidelines 2026
To understand how these changes will impact China’s patent examination system—especially for AI, big data, and digital media—we first need to look at what’s actually new in the 2026 update. China’s revised Patent Examination Guidelines, effective January 1, 2026, bring several big shifts aimed at improving patent quality and keeping pace with fast-growing technologies, such as:
- AI and data-driven inventions now need much clearer technical disclosure, covering things like algorithms, training data, and system workflows, and they must meet ethical and legal standards.
- Pure data or bitstreams can’t be patented anymore, but technical methods for encoding or processing them still can.
- Plant-related inventions also face new rules, requiring proof of human technical involvement since naturally occurring plants aren’t patentable.
- The commonly used dual-filing strategy—submitting an invention and a utility model on the same day—is now limited, and applicants must give up the utility model to get the invention patent.
- Divisional filings and priority claims are stricter, too, meaning small mistakes can have bigger consequences.
- Inventors must now be real people (not AI), and identity verification is tighter.
Overall, the new system is more structured, transparent, and technology-focused, but it also requires applicants to be more precise and thorough when preparing their patent filing.

How Will China Patent Examination Guidelines 2026 Impact AI and Digital Technology?
China’s patent examination process is basically getting a big upgrade—stricter, cleaner, and much more focused on real technology, such as:
- Examiners will now expect solid, detailed technical explanations, especially for AI, big data, and digital media inventions.
- If your patent application doesn’t clearly explain how the model works, how it was trained, or what real technical problem it solves, it’s likely to get rejected much faster than before.
- Claims based purely on data or algorithms won’t make it through anymore, but genuine technical solutions will move ahead more smoothly.
- The old dual-filing trick—submitting an invention patent and a utility model on the same day—is pretty much over, since you now have to give up the utility model to get the invention patent.
Conclusion
China Patent Examination Guidelines 2026 clearly show the country is raising the bar for innovation. With tighter rules, higher disclosure standards, and a stronger focus on real technical contributions, the patent examination system is becoming more reliable and future-ready. For applicants, this means being more careful, more detailed, and more strategic when filing. As China pushes toward cleaner, faster, and more tech-driven patent practices, staying updated and adapting early will be the key to securing strong protection in this new era of IP.
