Patent No. EP3831227 (titled "Aerosol Generating Device And Method And Program For Operating This") was filed by Japan Tobacco on Jul 30, 2018. The application was issued on Feb 19, 2025.
Aerosol generating device that enables early detection of aerosol source depletion through temperature monitoring. The device employs a sensor to measure temperature changes during the device's power cycles, with specific focus on temperature fluctuations after the device reaches a steady state. When the sensor indicates a significant deviation from the steady-state temperature, it triggers an alarm for potential depletion of the aerosol source in both the storage and holding units. This enables proactive management of the aerosol supply chain, allowing for timely intervention before the source depletes.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
