Patent valuation has historically relied on manual expert analysis, with assessment times averaging 12-15 hours per patent and significant variability between evaluators. Modern portfolios can contain thousands of assets, making comprehensive evaluation both time-intensive and inconsistent when relying solely on human analysis.

The fundamental challenge lies in developing objective, scalable methods to evaluate technical, legal, and commercial patent strength while maintaining accuracy across diverse technology domains.

This page brings together solutions from recent research—including machine learning approaches for claim analysis, natural language processing systems for technical depth assessment, and blockchain-based platforms for decentralized valuation. These and other approaches focus on creating reproducible scoring methods that can handle large patent portfolios while maintaining assessment quality.
