Worldwide Patent Search Scraper

Worldwide Patent Search Scraper

Search patents across Google Patents, USPTO, CNIPA, WIPO, CIPO, and India IPO with one query. Each result returns the title, inventors, assignee, abstract, status, and priority dates. Export to CSV, JSON, Excel, or XML.

Patent data is scattered across half a dozen national offices, each with its own search syntax and export limits. This Actor queries Google Patents, China's CNIPA, Canada's CIPO, USPTO PAIR, WIPO Patentscope, and India's IPO simultaneously from a single keyword search. It normalizes every match into one flat row so you can compare filings across jurisdictions without switching tools.

Filter by assignee, inventor, legal status, language, or priority date window before the run starts, and only the patents you need land in your dataset.

What it does

This Actor searches worldwide patent databases by free-text query and returns each patent as a flat row with its bibliographic details and legal status.

• 🌐 Multi-source search: query Google Patents, CNIPA, CIPO, USPTO PAIR, WIPO Patentscope, and India IPO in one run.
• 🔍 Free-text query with exact phrase support: use double quotes around "solar panel" to match the exact phrase.
• 🏢 Assignee and inventor filters: narrow results to a specific company or person before the data is collected.
• 📅 Priority date window: set a from-to range in YYYY-MM-DD format to study filings from a particular period.
• ⚖️ Legal status filter: collect only granted patents, only applications, or both.
• 🗣️ Language filter: restrict results to English, Chinese, German, French, Japanese, Korean, Spanish, or Russian.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

What you can do with Worldwide Patent Offices data

⚖️ Freedom-to-operate searches.

A patent attorney enters a client's technology keywords, filters by GRANT status and a date range, and reviews active patents that could block a product launch.

🏭 Competitor portfolio monitoring.

An R&D manager runs a weekly search filtered by a competitor's name in the assignee field to catch new filings as they publish.

📊 Cross-jurisdiction trend analysis.

A policy researcher collects all Chinese-language solar energy patents from CNIPA and WIPO over five years to compare filing velocity by country.

🔬 Prior art searches.

A patent examiner queries an exact phrase with all six sources enabled to find earlier publications that might invalidate a new application.

Troubleshooting

Why am I getting no results?

Check that your query is not too narrow. Remove the assignee, inventor, and status filters temporarily to see if the keyword alone returns matches. Also verify your date range is not excluding all filings.

Why are WIPO results missing assignee and status filters?

The assignee, inventor, status, and language filters are applied only to Google-Patents-backed sources. WIPO Patentscope is queried by keyword and date range only. This is a limitation of the WIPO search interface.

The run stopped before reaching my maxItems limit.

The Actor stops when the patent office returns no more results for your query. Try broadening your keywords, removing filters, or expanding the date range to find more patents.

Some fields are empty in my dataset.

Not every patent office publishes every field. For example, some jurisdictions may not provide an abstract or may list inventors differently. Empty cells mean the source office did not supply that data.

The run is taking a long time.

Searching multiple offices with a high maxItems value will take time because each office must be queried sequentially. Reduce the number of sources or lower maxItems for faster test runs.

FAQ

Question	Answer
Which patent offices does this Actor search?	It searches Google Patents (which covers over 100 jurisdictions), China's CNIPA, Canada's CIPO, USPTO PAIR, WIPO Patentscope, and India's IPO. You can enable all six or pick a subset in the Sources field.
Can I search by patent number instead of keywords?	The query field accepts free-text keywords. To find a specific patent by number, enter the number as your query. For exact matches, wrap it in double quotes.
What data fields does each patent row include?	Each row returns the patent title, abstract, inventors, assignee, application number, publication number, priority date, filing date, publication date, legal status, source office, and URL. The exact schema is shown in the sample output on the Actor's page.
Does the assignee filter work on all sources?	The assignee, inventor, status, and language filters are applied to Google-Patents-backed sources: Google Patents, CNIPA, CIPO, USPTO, and India IPO. WIPO Patentscope results are collected by keyword and date range only.
How do I search for an exact phrase?	Put the phrase in double quotes inside the query field. For example, "lithium ion battery" will match that exact phrase rather than each word separately.
What date format should I use for the priority date filters?	Use YYYY-MM-DD format. For example, 2020-01-01 for January 1st, 2020. Both dateFrom and dateTo are optional; leave one empty to search with an open start or end.
Can I export the results?	Yes. Apify supports exporting your dataset to CSV, JSON, Excel, XML, and several other formats directly from the run console.
Is there a limit on how many patents I can collect?	You set the limit with the maxItems field, up to 1,000,000 patents per run. The Actor stops when it reaches your number or when no more results match your query.
Does this Actor require API keys for the patent offices?	No. It reads the public search interfaces of each office. You do not need to register for any patent office API key.
Can I filter by legal status?	Yes. The status field lets you choose Granted patents only, Applications only, or Both. This filter applies to Google-Patents-backed sources.
