China CNIPA Patent Scraper

Scrape Chinese patent records from Google Patents with the CN jurisdiction filter applied. Returns bilingual data — English-translated titles and abstracts alongside the original Chinese — plus filing dates, assignees, inventors, CPC/IPC codes, legal event timelines, and patent family members.

Who Uses Chinese Patent Data?

• IP analysts — Track competitor filings, monitor classification clusters, build prior-art datasets
• Corporate R&D teams — Map who's filing what in China, and when. Useful before you spend a year on the same idea.
• Patent attorneys — Pull family members and legal-event histories for freedom-to-operate analysis
• Market intelligence — Detect filing surges in specific CPC codes as a leading indicator of where Chinese R&D money is going
• Academic researchers — Build longitudinal patent corpora filtered by date, assignee, or technology area

How the China CNIPA Patent Scraper Works

1. Pick a mode — Provide a search query, or paste specific patent URLs into startUrls. URLs win when both are set.
2. Search pagination — In search mode, the scraper hits Google Patents' JSON XHR endpoint with the country=CN filter and pages until it has enough patent IDs or hits Google's 1,000-result hard cap.
3. Detail extraction — Each patent's detail page is fetched through residential proxy and parsed for bibliographic data, classification codes, legal events, and the Chinese-source text.
4. Export — Records land in your Apify dataset as clean JSON, one record per patent.

FAQ

How do I scrape Chinese patents from CNIPA?

China CNIPA Patent Scraper handles it. Plug in a query, classification code, or assignee, set maxItems, and run. The scraper hits Google Patents with a CN-jurisdiction filter, which is the cleanest public surface for CNIPA data — and the only one that ships translated abstracts alongside the originals.

How much does this actor cost to run?

China CNIPA Patent Scraper uses pay-per-event pricing on the default_2603_basic profile at a 1.5x price coefficient. Residential proxy usage is included in the proxy tier. A 200-patent run typically costs a few cents in platform fees.

What data can I get for each patent?

China CNIPA Patent Scraper returns 20 fields per record: bilingual title and abstract, four key dates (filing, publication, grant, priority), inventors and assignees in both languages, CPC and IPC codes, legal event timeline, family members, and a direct PDF link. Enough to build prior-art datasets without scraping a second source.

Can I filter by date or classification code?

China CNIPA Patent Scraper accepts both. Use dateFrom/dateTo for priority date windows, and put a CPC or IPC code in the query field (e.g. H04L or G06F16/174). You can combine a classification code with a keyword if you want a narrower slice.

Does this actor need proxies?

China CNIPA Patent Scraper requires residential proxy. Google Patents returns a soft-block "Sorry" page to datacenter IPs, even on HTTP 200. The actor is preconfigured with Apify Residential — leave it alone unless you have a specific reason to override it.

Why Use China CNIPA Patent Scraper?

• Bilingual output — Returns both the Google-translated English and the original Chinese for titles and abstracts, so downstream tools can pick whichever they need.
• Search or seed — Run a broad keyword search across all CN patents, or paste a list of specific URLs when you already know which records you want. Both modes share the same parser.
• Structured legal events — Most patent scrapers give you a status string and call it done. This one ships the full event timeline (filings, grants, expirations) as JSON, which is what you actually need for due diligence.
