MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202621042871 A) filed by Yogesh Arjun Shinde; and Dr. Shrinivas K. Sonkar, Nashik, Maharashtra, on April 3, for 'blockchain base qr codes for detection of fake medicines.'
Inventor(s) include Yogesh Arjun Shinde; and Dr. Shrinivas K. Sonkar.
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: "The invention proposes a blockchain-based system to detect counterfeit medicines in the pharmaceutical supply chain. Each medicine unit is assigned a unique QR code at the manufacturing stage. The QR code is linked to verified product details such as manufacturer name, batch number, manufacturing date, expiry date, and distribution data. This information is stored securely on a blockchain ledger. Once stored, the data cannot be changed or deleted. As the medicine moves through distributors, wholesalers, and retailers, each transaction is recorded and validated on the blockchain. Every supply chain participant adds only authorized records. An authentication method is used to confirm the legitimacy of each transaction. When a consumer or pharmacist scans the QR code using a trusted application, the system checks the product details against blockchain records. If the data matches, the medicine is confirmed as genuine. If the QR code is missing, duplicated, or altered, the system flags the product as suspicious. This approach removes the need for a centralized database. It also improves transparency and traceability across the supply chain. The system helps regulatory authorities monitor medicine movement. It increases consumer trust and safety. The invention provides a practical, scalable, and reliable solution to reduce the circulation of fake medicines."
