MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202621030452 A) filed by Indian Institute Of Technology, Gandhinagar, Gujarat, on March 13, for 'system and method for controlled and verifiable multi-hop document retrieval.'
Inventor(s) include Hegde, Ravi Sadanand; Sarnaik, Tejas; and Shah, Manan.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to a computer-implemented retrieval control system (100) for controlled and verifiable multi-hop document retrieval from a corpus of digital documents. The system includes a graph memory (102) storing a symbolic entity-passage graph comprising entity nodes (102a), passage nodes (102b) and relational edges (102c). A policy engine (104) receives a query and generates a query-specific retrieval specification defining traversal constraints including seed entities, permissible edge types, traversal depth and resource limits. A compiler (106) converts the retrieval specification into a deterministic executable retrieval plan comprising a sequence of traversal operators. A traversal controller (108) executes the retrieval plan over the symbolic graph memory (102) to perform policy-guided multi-hop traversal, propagate relevance scores across entity nodes (102a) and identify relevant passage nodes (102b). The system outputs a response together with a verifiable evidence certificate characterizing the selected evidence passages and the executed traversal path."
