MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511117687 A) filed by Delhi Technical Campus, Greater Noida, Uttar Pradesh, on Nov. 26, 2025, for 'retrieval-augmented generation system.'
Inventor(s) include Dr. Upasna Joshi; Aman Kumar; and Uditanshu Pandey.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "A retrieval-augmented generation system, comprising a large language model 101 configured to generate natural language outputs using context from external documents. The system includes a document indexing subsystem 102 employing text embeddings and a vector database to store and retrieve heterogeneous formats such as PDF, TXT, DOCX, and webpages. A dynamic retrieval engine 103 selects relevant context based on real-time user queries, while a conversational processing module 104 maintains query history for multi-turn interactions. The system supports document summarization, question answering, and knowledge synthesis. The large language model 101 may be a Llama-4-Scout-17B model. The document indexing subsystem 102 may utilize Hugging Face embeddings with Chroma DB. A Streamlit-based user interface facilitates interaction. The system may include a debug mode for transparency and supports modular upgrades of key components, including the large language model 101, vector database, or interface."
