Disclaimer
- This service is provided free of charge by Hefei Zhihai Yida Patent Agency (General Partnership). “Free” means annual-fee monitoring and due-date reminders only; it does not constitute legal advice, an agency relationship, or a payment guarantee. Having us pay renewals on your behalf requires a separate paid engagement, or you may pay directly in the CNIPA official system yourself.
- Core data such as the annual-fee deadline, payable amount and legal status come from real-time public queries of the CNIPA official “Patent Business Processing System” (cponline.cnipa.gov.cn), based on the information published by the authorities.
- Currently we monitor Chinese mainland patents — invention, utility model and design — with the interface available in Chinese, English and Japanese. Overseas patent annuities are not yet covered by automatic monitoring.
- Due to data sync delays, emails being blocked or flagged as spam, or incorrect input, reminders may not be delivered on time or may be missed; we do not guarantee 100% accuracy. Always rely on official CNIPA notices and the patent register, and set up multiple reminders yourself.
- The obligation to pay annual fees and the consequences of late payment (e.g. termination of patent rights, surcharges) rest solely with the rights holder.
- The patent number, email and phone you submit are used only for annual-fee reminders and our notifications or promotional emails. We store them securely under the law and will not disclose them to unrelated third parties without consent (except where required by law).
- This service is free of charge; we are not liable for any loss caused by delayed, missed or failed reminders, or by system failures.
- By entering your email you agree to receive annual-fee reminders, service notifications and promotional emails from us, and may unsubscribe at any time via the link in the email or by replying “unsubscribe”. For questions, contact patent@zhihaiyida.com.
Frequently Asked Questions
What is free patent annuity monitoring?
A permanently free service by Hefei Zhihai Yida Patent Agency. Enter a patent number and we automatically track the annual-fee deadline for Chinese mainland patents (invention, utility model, design), emailing reminders before it lapses.
Is it really free? Any limit?
Completely free, unlimited number of patents, no hidden fees, forever.
Does free monitoring include paying the annuity for me? How do I pay when due?
The free service covers monitoring and reminders only — we track the deadline and notify you before it lapses; it does not include payment. Having us pay on your behalf is a separate paid engagement: each case is handled manually (time-consuming), and the fund transfer incurs applicable taxes/fees, so it requires a separate mandate and is billed accordingly. You can also pay entirely on your own: ① Log in to the CNIPA "Patent Business Processing System" (cponline.cnipa.gov.cn); ② Go to "Fee Payment Service — Online Payment — Fill Online"; ③ Click "Add", enter the patent number (13 digits only, without "ZL" or the decimal point) and the bill head; ④ Click "Query payable fees" and select the annual fee due (including any surcharge); ⑤ After saving, fill in the email and phone for the e-receipt; ⑥ Preview → generate order → pay (WeChat / Alipay / bank card / corporate account); ⑦ After payment, the e-receipt is available via the "E-receipt Delivery Service System" (pjonline.cnipa.gov.cn) or the WeChat/Alipay "电子票夹" mini-program.
Do I need to register an account or become a contracted client?
No. The service is fully open to everyone and self-service. You do not need to register an account, become a contracted client, or ask our staff to enter data manually. Just enter a patent number and your email on the monitoring page — monitoring is created and takes effect immediately. After submission we email you a link to "My Patent Annuity Dashboard"; the whole process is self-service.
Where does the monitoring data come from? Is it accurate?
Core data such as the annual-fee deadline, payable amount and legal status come from real-time queries of the CNIPA official "Patent Business Processing System" (cponline.cnipa.gov.cn), based on the information published by the authorities. We only display and remind; we never alter any official data. During official system maintenance or interface changes there may be brief delays — in that case the official site prevails.
Is my patent number and email safe?
Used only for reminders. Data is stored on our own servers, never sold or shared with third parties. You can cancel monitoring anytime.
Which patents are supported? Which countries/regions?
Currently we monitor Chinese mainland patents, covering the three types — invention, utility model and design — with the interface available in Chinese, English and Japanese. We do not yet directly monitor annuities for overseas patents (e.g. US/EU/JP/KR). For overseas patent monitoring, email patent@zhihaiyida.com to discuss a tailored solution.
How early do you remind me?
Email alerts at 30, 7 and 1 day before the deadline. After lapse we send periodic reminders flagging surcharge, restoration window and lapse risk.
I lost my dashboard link ("My Patent Annuity Dashboard") — what now?
After each submission we email the exclusive dashboard link to the address you provided; we suggest bookmarking it. If the link is lost or you did not receive it at a new address: ① return to the monitoring page and re-enter the same patent number and email — the system will resend the dashboard link; ② if it still does not arrive, check spam or email patent@zhihaiyida.com and we will resend it. The dashboard is accessed by link only — no account or password to remember.
When will annual-fee reminders stop?
Reminders pause or stop in two cases: ① legal status shows "rights maintained" — the annual fee has been paid and rights are valid, so there is no fee due and we will not remind again (you can still view it on the dashboard); ② legal status becomes "terminated", "invalidated", "rejected", "withdrawn" or similar — the rights no longer exist and monitoring stops automatically. You can also cancel monitoring for any patent at any time.
I missed a payment and it is overdue — what now?
We keep reminding you after lapse and clearly state whether you are in the surcharge period, the restorable window, or already lapsed, so you can act in time.
