What is included in the LexisNexis PatentAdvisor® API dataset?
The LexisNexis PatentAdvisor® API provides structured access to U.S. patent prosecution data, enabling you to analyze examiner behavior, prosecution patterns, and application outcomes.
The dataset includes more than 10.5 million USPTO patent applications dating back to 2001, along with detailed information on office actions, examiner activity, and prosecution history.
PatentAdvisor® API captures the full lifecycle of patent prosecution, including application filings, examiner interactions, office actions, and appeal outcomes. It enables you to assess how applications are examined and identify patterns that influence grant likelihood and prosecution timelines.
The dataset is designed for integration into internal systems and analytics platforms, allowing you to embed prosecution intelligence directly into your workflows.
What U.S. prosecution data coverage does PatentAdvisor® API provide?
PatentAdvisor® API provides comprehensive coverage of USPTO patent prosecution data, including:
10.5M+ patent applications
Historical coverage from 2001 to present
Examiner-level data across USPTO art units
Office actions and appeal-related information
The dataset focuses specifically on the U.S. patent system, providing deep insight into examiner behavior and prosecution outcomes within the USPTO.
This coverage enables you to analyze trends across examiners, technology areas, and application types, supporting data-driven prosecution strategies.
How is the prosecution data structured and delivered?
PatentAdvisor® API provides data structured around key prosecution entities, enabling flexible analysis and integration.
The dataset is organized around:
Applications (patent filings and prosecution history)
Examiners (behavior, decisions, and patterns)
Office actions (communications and examination steps)
Appeals and outcomes (decisions and prosecution results)
Common structured data elements include:
Application identifiers and filing details
Examiner and art unit information
Office action history and timelines
Allowance rates and prosecution outcomes
Appeal and decision data
This structure allows you to:
Analyze examiner behavior and decision patterns
Track prosecution timelines and outcomes
Compare performance across examiners and art units
Build custom analytics models and dashboards
Data is delivered via a real-time API, enabling direct integration into internal systems, applications, and analytics environments.
What additional data enrichments are included?
PatentAdvisor® API includes proprietary analytics and derived metrics designed to enhance prosecution analysis.
These include:
Examiner Time Allocation (ETA) – predicts the likelihood and timing of patent grant based on examiner behavior
Examiner performance metrics and allowance rates
Historical analysis of office actions and prosecution outcomes
Structured normalization of prosecution data for consistent analysis
These enrichments enable you to move beyond raw prosecution data and generate predictive insights into examiner behavior and filing strategy outcomes.
How frequently is the dataset updated?
PatentAdvisor® API provides real-time access to prosecution data, allowing you to retrieve the most up-to-date information available.
As new prosecution events occur (such as office actions or application updates), the dataset reflects these changes, enabling near real-time analysis of patent prosecution activity.
Can I customize or select the data I receive?
PatentAdvisor® API enables flexible data access through programmatic queries, allowing you to retrieve and analyze only the data relevant to your needs.
You can:
Filter data by examiner, art unit, or application characteristics
Retrieve specific subsets of prosecution data
Integrate data into internal systems and workflows
Combine prosecution data with internal business or portfolio data
This flexibility allows you to tailor prosecution analysis to your specific use cases, including filing strategy optimization and outcome prediction.
Summary
The LexisNexis PatentAdvisor® API provides comprehensive, structured access to U.S. patent prosecution data, enriched with proprietary analytics and predictive metrics.
By combining large-scale application coverage with examiner-level insights and real-time API delivery, PatentAdvisor® API enables you to analyze prosecution behavior, optimize filing strategies, and integrate prosecution intelligence into your internal analytics environments.
This makes it a powerful solution for organizations seeking data-driven insights into patent prosecution and examiner behavior.
