On October 14, 2026, China National Intellectual Property Administration (CNIPA) announced that, by joint decision of CNIPA and the Intellectual Property Office of New Zealand (IPONZ), the China–New Zealand Patent Prosecution Highway (PPH) pilot will be extended for five years from November 1, 2026 to October 31, 2031, with the requirements and procedures for filing PPH requests at both offices unchanged. This means Chinese applicants using New Zealand as a gateway for overseas patent protection can continue to rely on this fast-track examination channel to shorten time-to-grant. This article explains how PPH works, the key points of this extension, and the PPH network China has built.
1. What Is the Patent Prosecution Highway (PPH)?
The Patent Prosecution Highway (PPH) is a cooperative mechanism among patent offices of different countries or regions. When one or more claims in an application filed with a participating office are found allowable, the applicant may request accelerated examination of the corresponding application at another participating office. Offices reuse existing search and examination results (“work-sharing”), reducing duplication and significantly speeding up prosecution.
For applicants, the core value of PPH is speed and efficiency: it shortens the examination waiting time for overseas patents and helps secure rights sooner, and some offices reduce or waive fees for PPH requests. Note that PPH accelerates the process but does not change the substantive standards for grant.
2. Key Points of the China–New Zealand PPH Extension
According to the official announcement, three points matter:
- Clear extension term: the pilot is extended for five years from November 1, 2026, through October 31, 2031;
- No change to requirements or procedures: the conditions, documents, and procedures for filing PPH requests with both CNIPA and IPONZ remain as they were, so companies can proceed on the basis of existing experience;
- Stable cooperation: amid generally tight examination resources worldwide, a five-year, explicitly defined renewal gives companies a predictable framework for overseas layout.
3. China’s PPH Cooperation Network
The China–New Zealand PPH is not an isolated case. Since launching its first PPH pilot in November 2011, CNIPA has established PPH cooperation with the patent offices of 38 countries or regions, covering major innovation economies and several emerging markets — including Japan, Korea, the United States, the European Patent Office, Germany, the United Kingdom, and France, as well as a number of Belt and Road countries and regions closely tied to Chinese companies “going global.”
For businesses, this means that wherever the target market is a Chinese PPH partner, an applicant can turn allowable conclusions obtained at home or at another office into a “fast pass” for accelerated examination abroad, building a multi-jurisdiction grant strategy.
4. Practical Guidance: How to Use PPH Well
Drawing on prosecution practice, companies should consider PPH at these stages:
- Plan first, then accelerate: PPH usually requires the claims of the corresponding application to correspond to those already found allowable in the parent case, so plan claim correspondence with later countries at the very first filing;
- Link with annuity monitoring: obtaining a patent abroad is only the first step; annuity obligations run for the patent’s entire life. While accelerating grant, set up multi-jurisdiction patent annuity monitoring to avoid losing rights through missed payments;
- Align with market rhythm: match PPH acceleration with commercial milestones such as product launch, financing, or bidding so IP truly serves the business calendar;
- Watch office-specific rules: although the PPH concept is consistent, offices differ on timing, document formats, and fee waivers — verify the latest guidelines of the target office before filing.
5. Frequently Asked Questions
Q: What is the Patent Prosecution Highway (PPH)?
A: The PPH is a cooperative mechanism between patent offices. An applicant may request accelerated examination of a corresponding application at a partner office, based on claims already found allowable by another participating office, improving efficiency through shared search and examination work product.
Q: After the China–New Zealand PPH extension, do the requirements or procedures change?
A: No. The official announcement states that the requirements and procedures for filing PPH requests with both offices remain unchanged. The pilot is simply extended through October 31, 2031, so companies can continue as before.
Q: With how many countries/regions has China established PPH cooperation?
A: According to the latest official figures, CNIPA has established PPH cooperation with the patent offices of 38 countries or regions, covering major innovation economies and several emerging markets.
Q: How can Chinese applicants use PPH to obtain rights overseas faster?
A: Plan claim correspondence at the first filing, then request accelerated examination at a PPH partner office once the corresponding application has allowable claims, and fold post-grant annuity management into routine monitoring.
