PatentsView is phasing out our legacy API, making way for the more advanced and efficient PatentSearch API. In September 2024, we began the process of retiring the old API, with full discontinuation set for February 2025. 

We encourage all users to transition to the new PatentSearch API to ensure uninterrupted access to our services and to take advantage of the enhanced features and speed it offers.

About PatentSearch API

The new PatentSearch API is intended to inspire exploration and enhanced understanding of US intellectual property (IP) and innovation systems. The database for the PatentSearch API is updated regularly and features the best available tools for inventor disambiguation and data quality control.

Researchers and developers can use the API to uncover information about people and companies, and to visualize trends and patterns in the US innovation landscape.

The API offers seven unique endpoints that allow users to explore various questions, such as:

• Which companies hold patents in 3D printing? Discover their locations and the technologies they were innovating in before and after receiving 3D printing patents.
• What technology has been most commonly patented in the US in the last five years? Identify the top US and non-US cities producing these patents.
• Which US inventors earned the most patents in the last 30 years? Track their patenting activity, including the number and types of patents and their co-inventors.

Why Are We Switching APIs?

PatentsView has been offering an API since 2015, which has been widely used and valued by thousands of users. 

However, based on years of feedback and the evolving nature of patent data, PatentsView released the PatentSearch API in early 2024. This new API enhances the functionality and speed of the previous version.

Consolidating Names

Over time, the legacy API has been known by various names, including “PatentsView API,” “Swagger-based API,” and “MySQL API.” The new PatentSearch API has also been referred to as the “Elasticsearch API,” “Beta API,” and “Search API.” 

Moving forward, we will consolidate the naming to its official title – PatentSearch API.
