Solution Overview

Problem

Current e-discovery systems lack an efficient and accurate method for purging data based on business rules, leading to inefficient manual processes and potential errors in data retention and removal, especially in large corporate environments with diverse business entities and complex data storage requirements.

Innovation Solution

An automated file purge system that determines files eligible for purging based on predefined business rules, locates them within the e-discovery file system, and automatically removes the data, while also tracking the purge process and notifying relevant parties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual purging of data is implemented, then flexibility in applying business rules is improved, but accuracy and efficiency deteriorate due to human error and time consumption

Engineering Contradiction:
Improveflexibility in applying business rulesVSAvoidaccuracy of data purging
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system enables self-service automation where the purge application automatically evaluates files against stored business rules and criteria without human intervention. The system self-determines which files qualify for purging based on predefined policies, eliminating manual assessment while maintaining rule flexibility through programmable business logic that can be adjusted without manual reconfiguration of the entire system.

Inventive Principle:
Principle #25Self-service

2Productivity

If automated purging at case level is implemented, then efficiency is improved, but precision deteriorates because individual business rules for different entities cannot be applied

Engineering Contradiction:
Improveefficiency of data purgingVSAvoidprecision of purge criteria application
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system segments the purging process into hierarchical levels: case-level automation for efficiency and file-level precision for accuracy. Business rules are segmented into different scopes (case-level rules and file-level rules), allowing automated evaluation at both levels. The system processes files individually within cases, applying entity-specific rules to each file while maintaining overall case-level automation control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies local quality by allowing different business entities, lines of business, and file types to have customized purge rules and criteria. Each file can be evaluated against specific business rules relevant to its category, while the overall system maintains automated efficiency. This enables precise application of local business requirements without sacrificing global automation benefits.

Inventive Principle:
Principle #3Local quality

3Reliability

If data is permanently retained in storage, then compliance with retention policies is improved, but storage capacity requirements and security risks increase

Engineering Contradiction:
Improvecompliance with retention policiesVSAvoidstorage capacity requirement
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The system implements periodic action by automatically evaluating files at scheduled intervals against retention policies and business rules. Rather than permanent retention or one-time manual purging, the system continuously monitors file eligibility and automatically purges qualifying files when conditions are met, maintaining compliance while optimizing storage utilization over time.

Inventive Principle:
Principle #19Periodic action

4Quantity of substance

If extensive infrastructure for data storage is implemented, then data retention capability is improved, but cost and complexity increase

Engineering Contradiction:
Improvedata storage capacityVSAvoidinfrastructure complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The system implements feedback mechanisms that monitor storage conditions, file eligibility, and purge outcomes to dynamically adjust retention decisions. The automated evaluation system provides continuous feedback on which files qualify for purging based on business rules, enabling optimized storage utilization without requiring excessive infrastructure capacity or manual management complexity.

Inventive Principle:
Principle #23Feedback

AI summary

Embodiments of the invention relate to systems, methods, and computer program products for automated data purge in an e-discovery system. The automated data purge process determines files within an e-discovery file system that qualify for purging based on one or more purge policies, locates the files within the file system and automatically purges the data from the file system. Additional embodiments provide for automatically creating log entries that track the details of the purge and automatically generating and communicating alerts/messages that notify concerned parties of the data purge. As such the present invention is able to accurately and automatically purge data from an electronic discovery file system and provide for detailed purge data tracking, as well as, purge notification.
