MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202621029495 A) filed by Indian Institute Of Technology, Maharashtra, on March 12, for 'a system and method for lifecycle traceability of physical entities using a time-aware digital thread.'
Inventor(s) include Ogale, Amogh Sharadchandra Anuradha; and Kulkarni, Makarand S.
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: "A system and method provide lifecycle traceability of physical entities in complex industrial environments by establishing a persistent, time-aware digital thread for each lifecycle-bearing physical entity. A persistent global identity is assigned to the physical entity independent of equipment hierarchy and independent of local identifiers of heterogeneous stakeholder systems. Lifecycle data is obtained from manufacturing, operational, maintenance, and logistics systems without modifying the source systems. A separate integration knowledge structure is constructed to represent the physical entity and a sequence of discrete lifecycle events, each event having explicit temporal validity and a source reference to an originating stakeholder record. The lifecycle events are temporally ordered to form a continuous digital thread that remains intact across removal, repair, storage, cannibalisation, and redeployment. Time-aware queries reconstruct the entity's state and context at a selected time, and the digital thread supports deterministic traceability, explainability, and reliability computation using cumulative exposure."
