How this service works
Google Patents: Google Patents results, returned as JSON. Structured JSON, USD 0.05 per call in USDC — no API key, no account, no subscription, no minimum. Not affiliated with, endorsed by or an official channel of any of the services the results come from. All trademarks and copyright remain the property of their respective owners.
Output
A structured JSON object containing a list of patent results, each with fields such as patent title, patent number, link, assignee, inventor(s), filing date, priority date, publication date, patent status (grant or application), country, abstract snippet, and optionally Google Scholar results if enabled.
Example use cases
Competitor patent landscape research
“Search Google Patents for any patents assigned to Tesla related to 'battery thermal management', filter to granted patents only, sort by newest, and give me the first 20 results.”
Prior art search before filing
“I'm about to file a patent — can you search Google Patents for 'transformer-based speech synthesis' to find prior art, show applications and grants from the US and WO, sorted by relevance, 20 results?”
Inventor portfolio lookup
“Find all Google Patents invented by Geoffrey Hinton related to 'neural network', sorted by newest filing date, 25 results per page.”
Technical details
Endpoint
POSThttps://serp402.com/api/v1/google-patents?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable Google Patents search results via a pay-per-call model with no API key or subscription required. It is ideal for agents that need to search patents programmatically, filter by assignee, inventor, country, status, or date range, and paginate through results. Prefer this over scraping Google Patents directly (which risks blocks) or over SerpAPI/Bright Data if you want a low-commitment per-call USDC micropayment model without account setup.
Side effects
- Invalid or missing query parameter returns an error response
- Unsupported country code causes filtering to fail or return empty results
- Date format not matching type:YYYYMMDD pattern causes parameter rejection
- Requesting num outside 10-100 range may return an error or be clamped
- No results found for highly specific queries returns empty results array
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
