CNIPA Correction Notice (补正通知) — 30-Day Response Tracker

When your trademark application has a formal / paperwork defect (missing signature, wrong class number, unclear goods list), CNIPA sends a Correction Notice (补正通知), not a refusal. You have 30 calendar days from receipt to fix and resubmit — no official fee, but if you miss it the application is refused outright. Enter the receipt date below.

Do not confuse this with a refusal review. A correction notice is a paperwork fix: 30 days, no fee, and your filing date is preserved if you fix on time. A refusal (驳回通知) is a substantive rejection: only 15 days, CNY 675/750 review fee, and missing it means the mark is dead. Read the notice's Chinese title carefully before you act.

Date you / your Chinese agent actually received the correction notice (补正通知收到日) for electronic service, use the date shown as served in the CNIPA online system — not the date the notice was generated
