Genomic Patent Claims & Prior Art Audit Agent with LangChain

Evaluating complex genomic liquid biopsy patents against prior art requires precise legal and technical analysis. Build a LangChain and LangGraph stateful auditing agent to extract patent claim vectors, compare sequencing assay methodologies, and produce structured patent novelty risk reports.

What you are building

Develop a stateful LangChain and LangGraph workflow to parse liquid biopsy genomic patent claims and evaluate prior art overlap.

How work is evaluated

Evaluation

Evaluates state graph claim extraction accuracy and prior art overlap similarity scoring.

Datasets

Public datasets, plus the private datasets you have access to.

How submissions are scored

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

Risk Level Classification Check

Verifies risk level output is assigned to Low, Medium, or High.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

Similarity Correlation

Pearson correlation between model similarity score and legal expert overlap scores. • target: 0.85 • range: -1-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

  • Construct stateful LLM computational graphs using LangChain and LangGraph.

  • Parse and vector-index complex patent claim legal text and genomic assay methods.

  • Implement similarity scoring algorithms to identify overlapping prior art in sequencing protocols.

  • Export structured patent infringement risk matrices.

Resources

Dataset notes
