Innovation Solution

Utilizing a Robustly optimized Bidirectional Encoder Representations from Transformers (RoBERTa) model with a sub-word approach and fuzzy matching algorithm to analyze subpoenas, extracting and linking relevant information, and generating reports for compliance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated processing systems are used to handle subpoenas, then processing speed and productivity are improved, but accuracy and completeness may deteriorate due to complexity of formats and diversity of authorities

Engineering Contradiction:

Improveprocessing speedVSAvoidaccuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system incorporates human review capabilities where professionals can correct and verify automated extractions. This feedback loop allows continuous improvement of the automated system's accuracy while maintaining high processing speeds through automation of routine tasks.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system uses universal templates and adaptive algorithms that can handle diverse subpoena formats from different authorities. The template-based approach with dynamic content areas allows a single system to accurately process various formats without sacrificing precision for any specific authority type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If comprehensive extraction of all information is performed, then completeness is improved, but processing time and complexity increase

Engineering Contradiction:

ImprovecompletenessVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system segments the subpoena processing into distinct modules: format detection, template matching, information extraction, validation, and review. This segmentation allows comprehensive extraction to be performed systematically through ordered steps rather than monolithic processing, improving completeness while managing time through efficient step execution.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by pre-loading appropriate templates and preparing extraction parameters before processing each subpoena. This preliminary preparation enables rapid comprehensive extraction without time-consuming on-the-fly decisions, as the framework and criteria are ready in advance.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the system handles diverse formats from multiple authorities, then adaptability is improved, but device complexity and difficulty of operation increase

Engineering Contradiction:

Improveformat flexibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system employs a universal template framework that can accommodate multiple subpoena formats through a single unified structure. This universality allows the system to handle diverse authorities and formats without increasing operational complexity, as all formats are processed through the same standardized template mechanism.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system creates standardized representations (copies) of subpoena information through templates, transforming diverse formats into uniform data structures. This copying approach simplifies complexity by converting varied input formats into a consistent internal representation, making the system easier to operate while maintaining adaptability.

Inventive Principle:

Principle #26Copying

4Reliability

If scanned documents are processed, then completeness of physical evidence is improved, but processing difficulty and time increase compared to digital documents

Engineering Contradiction:

ImprovecompletenessVSAvoidprocessing difficulty

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The system performs preliminary optical character recognition (OCR) processing to convert scanned documents into machine-readable text before extraction. This preliminary action transforms the difficult-to-process scanned format into an easier-to-process digital text format, maintaining completeness of scanned documents while significantly reducing processing difficulty and time.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method and a system for preparing a response to a subpoena by using an automated subpoena processing and handling model is provided. The method includes: receiving a first subpoena; extracting a set of informational requests from the first subpoena; retrieving a data set from a memory; analyzing the first data set with respect to the set of informational requests in order to identify items from within the data set that are responsive to items included within the set of informational requests; and generating a report that includes a result of the analysis. The analysis is performed by providing the first subpoena as an input to a Robustly optimized Bidirectional Encoder Representations from Transformers pre-training approach (RoBERTa) model that uses a sub-word approach to modeling words in a sequential format.
