Google Patents Scraper — Search Patents by Assignee, Inventor & Date (No API Key)

Search millions of patents on Google Patents and export them as structured data — no API key, no login. A single query can match hundreds of thousands of patents; this actor paginates up to Google's 10,000‑result window per query and returns clean bibliographic records.

Google Patents has no official API, and paid providers (SerpApi, Scrapingdog) charge for exactly this. This actor talks to the same public xhr/query endpoint the website uses.

⚠️ Google blocks datacenter IPs on this endpoint. The actor uses Residential proxy by default — keep it on.

Use cases

• Competitive & IP intelligence — monitor a competitor's entire patent portfolio.
• Prior‑art & freedom‑to‑operate — bulk pull a technology space for review.
• R&D and tech scouting — track filings by topic, assignee, or inventor over time.
• Datasets — build patent corpora for analytics or ML without a paid API.

FAQ

Do I need a Google/API key? No. It reads a public endpoint.

Why residential proxy? Google returns a block page to datacenter IPs on this endpoint. Residential is the default and is required.

How many patents per query? Up to 10,000 (Google's 100‑page × 100‑result window). Use date ranges or assignee filters to slice larger spaces into multiple runs and go beyond that.

Can I get the full patent text / claims? This actor returns the search record (title, abstract snippet, bibliographic data, PDF link). Open the pdfUrl for the full document.
