China Patent Search — CN Publications (CNIPA Records via Google Patents Index)

Data source: this actor queries the Google Patents index (patents.google.com) filtered to CN publications, i.e. patents filed at CNIPA as Google indexes them. It does not call CNIPA's own search service.

Search China CNIPA patents with abstracts, claims and citations. Built for analysts, quants, fintech builders and AI agents.

💰 Pricing

Event	Price (USD)	When it is charged
Actor Start (apify-actor-start)	$5e-05	Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event).
Patent (apify-default-dataset-item)	$0.05	Charged per CNIPA patent record returned

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.05 = $5.00 plus the start fee.
