Stay Ahead: Getting a Chinese Patent in Three Months?

The China National Intellectual Property Administration (CNIPA) has announced a significant development in the realm of patent prosecution: the initiation of the “PPH Improvement Initiative” in collaboration with key patent offices from the United States, Europe, Japan, and South Korea. This initiative aims to elevate the user experience of the Patent Prosecution Highway (PPH) by setting ambitious targets for the average cycle time of the first office action and the average cycle time for replying to applicants’ responses, both now set at three months starting from 2024.

Here’s a concise summary of the specific changes:




Average Cycle Time for First Notice1

Within Four Months

Within Three Months

Average Cycle Time for Replying to Applicants’ response


Within Three Months

The PPH serves as an expedited patent examination pathway between different countries or regions, facilitating quicker patent examination processes through shared work among patent examination authorities. Since its inception in November 2011, CNIPA has established PPH cooperation with patent offices in 32 countries or regions.

In order to enhance the predictability of PPH application examination timelines, ongoing discussions among the IP52 have led to this initiative. Initially proposed by Japan and the United States, China’s active participation underscores its commitment to this policy. Ideally, receiving a notice of grant within three months (or even shorter) is now within reach.

For enterprises aiming to penetrate global markets, this improvement policy promises to make examination timelines across different countries more predictable. It is anticipated that this will enable companies to manage their intellectual property systematically and strategically expand into the global market.
