Patra, an outcome-focused operating partner for the insurance sector, has been granted a US patent for the technology that powers its Policy Checking AI. The patent, issued on May 26, 2026, covers a method for automatically extracting values from insurance documents and guiding human reviewers to the details that need attention - a process that predates the recent surge in generative and agentic AI.
The United States Patent and Trademark Office issued US Patent No. 12,639,972, titled "Systems and Methods for Value Extraction and Guided Review." Patra chief technology officer Tony Li and senior director of AI engineering Juan Cristian Martinez Vega are named as inventors, with Patra Corporation as the sole assignee.
How the patented technology works
The protected invention scans a file, maps where each word sits on the page, and pinpoints the items a user wants to extract. It then determines the value most likely linked to each item and prompts the user to verify the result. A feedback loop built around expert review means the system's accuracy improves over time.
A human-in-the-loop design that predates the AI boom
In daily use, the technology enables quicker and more precise policy checking. The AI handles search and extraction across long policy documents while a Patra specialist retains authority over the final decision. The patent carries a priority date of February 2022, meaning the approach was developed well before the wave of generative and agentic AI reshaped the market.
Patra's position in insurance operations
Patra works exclusively with the insurance industry, drawing on 20 years of domain knowledge and ongoing investment in AI for Insurance. The company partners with agencies, brokers, MGAs, MGUs and carriers to reshape insurance operations, pairing an agentic platform and process intelligence with expert teams to deliver measurable results.
Patra CEO Pratap Sarker said, "We were building governed, expert-supervised AI with real review at the center of the process before that became the industry's accepted position. That same conviction guides the agentic platform we're building now: capable, inspectable, and governed by design, with a person able to step in at any time."
That platform, which combines process intelligence with expert oversight, is part of the company's push into AI Agents & Automation. Patra senior director of AI engineering Cristian Vega said, "This patent illustrates the foundation of the AI and human-in-the-loop mechanisms that are still at the core of what Policy Checking AI is today. More importantly, it supports the needs of our clients and the carriers and regulators who increasingly expect explainable, documented AI use with meaningful human oversight."
Why this matters for insurance professionals
The patent formalizes a practical, expert-supervised approach to AI that aligns with regulatory expectations for transparency and human oversight. For insurance professionals, the technology behind Patra's Policy Checking AI offers a model for how automated document review can speed up policy checking without removing the specialist from the decision loop - a balance that regulators and carriers are demanding as AI adoption accelerates.
