Google Patents API

Google Patents API allows you to get the inventor's name, filing date, assignee & publication number with a simple API request. The API manages proxies and all corner cases to get patents data at scale.

Scrapingdog vs Manual Google Patents Scraping

Without a Google Patents API

Scraping Google Patents by hand means wrestling patent PDFs and figure images, reconciling filing dates, and normalizing assignee and inventor names across languages.

  • Patent PDFs & Figure Images Locked Away

    Full-text claims, drawings, and figures live in scanned PDFs and image files, so extracting them for prior-art review is slow OCR work.

  • Inconsistent Assignee & Inventor Names

    The same applicant appears as different strings across jurisdictions and in non-Latin scripts, breaking ownership analytics.

  • Tangled Dates & Country Status

    Priority, filing, grant, and publication dates plus per-country legal status must be reconciled before any FTO or expiry call.

  • Pagination, Sorting & Citation Crawling

    Boolean queries, pagination, date and status filters, and citation links each need their own crawler logic for a complete set.

  • I got the free trial and in less than a minute I already integrated with their API to scrape Google. As a matter of fact they had all the plug-and-play codes ready for me, it was seamless. I am about to upgrade as I have used up my trial credits.
