Formally Verified Patent Analysis via Dependent Type Theory: Machine-Checkable Certificates from a Hybrid AI + Lean 4 Pipeline
A Lean 4 system models patent claims as DAGs with match scores in a verified complete lattice and supplies kernel-checked certificates for coverage calculations and five IP use cases, conditional on unverified ML inputs.
