Google Patents Details API
Google Patents Details API allows you to scrape patent details or scholar details from Google Patents. The API is accessed through the following endpoint: /search?engine=google_patents_details. A user may query the following: https://serpapi.com/search?engine=google_patents_details utilizing a GET request. Head to the playground for a live and interactive demo.
API Parameters
Search Query
patent_id
Required
Parameter defines the ID of the patent you want to retrieve. You can get it from the results of our Google Patents API.
It can be:
- A patent ID: patent/<publication number>/<two-letter country code>, the country code can be omitted (e.g. patent/US11734097B1/en or patent/US11734097B1)
- A scholar ID: scholar/<scholar ID> (e.g. scholar/6497879044063343659)
Serpapi Parameters
engine
Required
Set parameter to google_patents_details to use the Google Patents Details API engine.
no_cache
Optional
Parameter will force SerpApi to fetch the Google Patents Details 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.
API Results
JSON Results
JSON output includes structured data for patents results.
A search status is accessible through search_metadata.status. It flows this way: Processing -> Success || Error. If a search has failed, the error will contain an error message. search_metadata.id is the search ID inside SerpApi.
HTML Results
HTML output is useful to debug JSON results or support features not supported yet by SerpApi.
HTML output gives you the raw HTML results from Google Patents Details.
