The client was developing a personalized BRCA gene panel designed to support breast cancer analysis by combining genomic information from multiple biological and clinical sources. The objective was to identify potentially relevant patent rights across the United States, India and WIPO jurisdictions that could overlap with key elements of the invention.

The investigation focused on understanding whether existing patent claims covered critical technical components, including AI-assisted genetic information processing, biomarker prioritization, custom panel generation and genomic database management.

The invention primarily involved:

- Aggregation of genetic information from multiple sources, including genomic databases, clinical trial data and commercial gene panels.
- Application of a rank aggregation algorithm to prioritize genes for inclusion in a customized breast cancer genomic panel.
- Generation and storage of a customized BRCA gene panel within a genomic database for subsequent analysis and integration.
- Continuous updating of the genomic database with newly available genetic and clinical information to maintain the relevance of the customized panel.
- Evaluation of HRR and pharmacogenomic (PGx) genes and mutations to support personalized assessment of treatment responsiveness.

CLIENT’S OBJECTIVE

Identify potentially relevant patent claims that could overlap with the customized BRCA testing panel and its underlying genomic data-processing workflow across the US, India and WIPO jurisdictions.

Identify potential patent constraints early enough to support technology refinement and informed product-development decisions before commercialization.

Traditional FTO Investigation Approach

The investigation initially followed a conventional Freedom-to-Operate (FTO) search methodology, focusing on identifying active and pending patent rights that could potentially overlap with the customized BRCA testing panel.

The search examined disclosures across standard patent and technical sources, including:

Conventional Investigation Strategy

Patent claims and specifications

IPC/CPC classification-based searches

AI-based genetic analysis disclosures

Breast cancer biomarker and testing panel references

Patent citations and similar patent documents

The search identified several references covering AI-based genomic analysis, cancer biomarkers, genetic scoring, diagnostic panels and genomic databases. However, the relevant disclosures were often fragmented.

Limitations of Traditional Approaches

Broad AI and genomic patents lacked specific disclosures on gene ranking and customized BRCA panel generation.
Cancer diagnostic patents emphasized biomarker scoring and genetic analysis, rather than pre-panel genetic prioritization.
Individual references rarely connected somatic/germline mutations, HRR, pharmacogenomics and treatment-response relationships.
Genomic database patents lacked clear connections between continuous updates, biomarker prioritization and customized panel generation.
Relevant technical features were distributed across references, requiring cross-comparison to assess potential overlap.

As a result, relying exclusively on conventional keyword-driven FTO searching risked overlooking patents that used different terminology to disclose technically relevant components of the customized BRCA panel workflow.

Wissen's Out-of-the-Box Approach

Technology-Centric FTO Through Patent Architecture Analysis

Recognizing the limitations of conventional keyword-driven FTO searching, the investigation evolved toward a technology-centric analysis of the complete genomic panel workflow.
To develop a broader and more precise assessment of potential patent overlap, the investigation expanded beyond isolated BRCA or cancer-testing terms to examine the underlying technical processes that were:

Used to aggregate genetic information from multiple sources
Applied to rank and prioritize genes before panel generation
Used to construct customized genomic panels

Identifying Relevant Patent Families

A focused technical investigation was conducted on patent references addressing genomic data processing, biomarker prioritization, cancer-specific panel generation and genetic analysis.
However, conventional searches frequently identified patents covering individual components rather than the complete customized BRCA panel workflow.

To overcome this limitation, targeted assignee-based searches were combined with technical keywords, classifications, citation analysis and claim-level review to uncover references with stronger overlap with the client’s technology.

Technical Challenges Addressed Through Technology-Centric FTO Analysis

Challenge 1: Identifying Gene Prioritization Before Customized Panel Generation

One of the key technical questions involved determining whether existing patents disclosed the ranking and prioritization of genetic information before creating a customized breast cancer gene panel, rather than merely scoring genetic variants after panel generation.

Solution

A detailed patent investigation was conducted across genomic analysis, cancer diagnostics, biomarker selection, and AI-based genetic data processing. The analysis examined how genetic information from different sources was processed and prioritized for panel construction.

The analysis revealed:

Gene ranking based on cancer relevance
Alteration frequency-based prioritization
Integration of commercial panel information
Algorithmic biomarker selection
Customized genomic panel formation

These findings helped distinguish patents addressing pre-panel gene prioritization from references focused primarily on downstream genetic scoring or diagnostic interpretation.

Challenge 2: Connecting Genomic Database Updates With Customized Panel Development

Another important technical question involved determining whether existing patent disclosures connected continuously updated genomic databases with the generation and maintenance of customized cancer testing panels.

Solution

The investigation examined patent references describing genomic databases, genetic information processing, biomarker repositories, and cancer diagnostic systems. Particular attention was given to how newly available genetic information was incorporated into databases and subsequently used within diagnostic workflows.

The analysis revealed:

Continuously updated genomic databases
Integration of new genetic findings
Database-driven biomarker evaluation
Genetic marker storage and retrieval
Panel information maintenance mechanisms

These findings helped assess the potential overlap between existing database technologies and the client’s proposed workflow for maintaining an evolving customized BRCA testing panel.
