What is the LexisNexis® Patent Prosecution API?
The LexisNexis® Patent Prosecution API provides structured access to U.S. patent prosecution data, enabling you to integrate examiner analytics and prosecution insights directly into your internal systems, analytics platforms, and workflows.
The dataset covers more than 10.5 million USPTO patent applications dating back to 2001, providing detailed insights into examiner behavior, office actions, and prosecution outcomes. It includes proprietary analytics designed to help you understand how patent applications are reviewed and how likely they are to be granted.
A key feature of the dataset is the Examiner Time Allocation (ETA) metric, which predicts both the likelihood and timing of patent approval based on historical examiner behavior.
The Patent Prosecution API is used to forecast prosecution outcomes, optimize filing strategies, evaluate examiner behavior, and analyze office actions and appeals.
It is typically used by patent attorneys, in-house IP and R&D teams, law firms, and enterprise data and analytics teams integrating prosecution insights into internal systems.

By providing structured, analytics-ready data, LexisNexis® Patent Prosecution API enables more informed decision-making throughout the patent filing process.
How does it differ from the LexisNexis PatentAdvisor® platform?
The LexisNexis PatentAdvisor® platform is a SaaS application that provides interactive tools, dashboards, and visualizations for analyzing patent prosecution and examiner behavior.
The LexisNexis® Patent Prosecution API, by contrast, provides direct access to the underlying prosecution dataset, allowing you to integrate this data into your own tools, workflows, and analytics environments.
This allows you to:
Combine prosecution data with internal business or portfolio data
Build custom dashboards and reporting tools
Automate prosecution analysis workflows
Integrate insights into internal systems and applications
Many organizations use both solutions together involving the use of the PatentAdvisor platform for interactive analysis, while leveraging the API for deeper integration and automation.
Data Delivery Options
The Patent Prosecution API is delivered through a real-time API, enabling you to retrieve and integrate prosecution data directly into your systems.
API Access
The API provides:
Real-time access to USPTO prosecution data
Structured application and examiner-level data
Integration into internal tools, applications, and analytics platforms
Ability to filter and monitor applications by examiner, art unit, and other criteria
This allows you to embed prosecution insights directly into your workflows and automate data retrieval and analysis.

Summary
The LexisNexis® Patent Prosecution API provides direct access to one of the most comprehensive U.S. patent prosecution datasets available.
By delivering structured examiner analytics, prosecution data, and predictive metrics such as ETA through a real-time API, it enables you to integrate prosecution intelligence directly into your systems and workflows.
This makes the Patent Prosecution API an ideal solution for organizations seeking data-driven prosecution strategy, improved filing outcomes, and deeper integration of patent insights into their analytics environments.
