The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "An immutable graph data structure for concurrent query processing comprises a graph repository (101), a version anchor (102), a vertex catalog (103), an edge segment store (104), a relationship index (105), a query admission manager (106), a version publication controller (107), and a retirement tracker (108). A published graph version is exposed through the version anchor (102) and remains immutable during query execution. Revised versions are assembled using structural sharing and atomically published. Query sessions receive version tokens for stable traversal, while superseded versions are retired only after dependent sessions complete."
