Overview
The USPTO API provides access to US patent data including full-text patents, patent grants, and trademark records. You can search patents by keyword, inventor, or filing date. It is a great resource for researchers and developers interested in intellectual property data.
Beginner Tip
Start with the Open Data Portal at developer.uspto.gov for cleaner REST endpoints. The main site URL points to documentation, so look for the PatentsView or BDSS API for programmatic access.
