Vaporizer Device With Variable Booster Circuit
Patent No. EP4147535 (titled "Vaporizer Device With Variable Booster Circuit") was filed by Juul Labs on May 7, 2021. The application was issued on Dec 10, 2025.
Patent Summary
A vaporizer device comprises a power source, a heating element for vaporizing material, a controller, and a variable boost circuit. The boost circuit operates in two modes: a bypass mode, delivering a first output voltage corresponding to the power source voltage, and a non-bypass mode, delivering a second output voltage exceeding the power source voltage. The controller determines the operational mode based on measurements associated with the heating element to reach a target temperature. Specifically, when the controller selects the bypass mode, it is configured to adjust the duty cycle at which the first output voltage is applied to the heating element. The device may further determine the mode based on duty cycle thresholds or target power levels derived from temperature differentials.

Patent Oppositions
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.
Dossier Documents
The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
