This is the Swagger Demo matching the example shown in this article.

Click "Try it Out" below then scroll down and press "Execute" to send a pre loaded request to the API and receive actual responses from the API!

The full Swagger 3.0/OpenAPI version is at https://mustberuss.github.io/Patentsview-Swagger/patentsviewswagger3.html

Note that this is the Swagger-UI page for the original version of the Patentsview API. The new version of the API requires an API key which isn't so handy for a quick demo.
