MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511113776 A) filed by Chandigarh University, Mohali, Punjab, on Nov. 19, 2025, for 'anti-theft sim locking mechanism to prevent deactivation of device tracking.'
Inventor(s) include Annanya Nayar; Ramit Chaturvedi; Laksh Kapoor; Kulvinder Singh; and Aleem Ali.
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: "The present invention relates to a hardware-based anti-theft SIM locking mechanism for mobile communication devices that prevents unauthorized removal of the Subscriber Identity Module (SIM) card, thereby maintaining continuous device traceability. The system comprises a microcontroller, an actuator and a metal locking tooth integrated within the SIM tray assembly. The microcontroller governs the actuator to control the position of the metal tooth, which mechanically locks or unlocks the SIM tray based on authentication input from the user. When an authorized user enters a valid password, PIN or biometric data, the actuator retracts the locking tooth, allowing the SIM tray to open. Unauthorized attempts to eject the SIM tray keep the mechanism locked, preventing SIM removal. This ensures that the device remains connected to cellular networks and can be tracked using existing services such as "Find My Phone" or IMEI-based tower registration, thereby safeguarding user data and improving device recoverability."
