Google Patents API
Google Patents API allows you to scrape patent and scholar results from Google Patents. The API is accessed through the following endpoint: /search?engine=google_patents. A user may query the following: https://serpapi.com/search?engine=google_patents utilizing a GET request. Head to the playground for a live and interactive demo.
API Parameters

List of supported values are:new - Newestold - Oldest
Patent results are sorted by filing_date while scholar results are sorted by publication_date for new and old values.
clustered
Optional
Parameter defines how the results should be grouped.
List of supported values are:true - Classification
dups
Optional
Parameter defines the method of deduplication. Either Family (default) or Publication.
List of supported values are:language - Publication
Date Range
Advanced Filters
country
Optional
Parameter filters patent results by countries. Split multiple country codes with , (comma).
List of supported country codes.
Example:WO,US.
language

Optional
Parameter filters patent results by status.
List of supported values are:GRANT - GrantAPPLICATION - Application
Serpapi Parameters
no_cache
Optional
Parameter will force SerpApi to fetch the Google Patents results even if a cached version is already present. A cache is served only if the query and all parameters are exactly the same. Cache expires after 1h. Cached searches are free, and are not counted towards your searches per month. It can be set to false (default) to allow results from the cache, or true to disallow results from the cache. no_cache and async parameters should not be used together.
async
Optional
Parameter defines the way you want to submit your search to SerpApi. It can be set to false (default) to open an HTTP connection and keep it open until you got your search results, or true to just submit your search to SerpApi and retrieve them later. In this case, you'll need to use our Searches Archive API to retrieve your results. async and no_cache parameters should not be used together. async should not be used on accounts with Ludicrous Speed enabled.
zero_trace
Optional
Enterprise only. Parameter enables ZeroTrace mode. It can be set to false (default) or true. Enable this mode to skip storing search parameters, search files, and search metadata on our servers. This may make debugging more difficult.
API Results
JSON Results
JSON output includes structured data for Organic Results and Summary.
A search status is accessible through search_metadata.status. It flows this way: Processing -> Success || Error. If a search has failed, error will contain an error message. search_metadata.id is the search ID inside SerpApi.
HTML Results
This API does not have html response, just a text. search_metadata.prettify_html_file contains prettified version of result. It is displayed in playground.
