Patent No. EP3928646 (titled "Vaporization Device Systems And Methods") was filed by Juul Labs on Dec 23, 2014. The application was issued on Mar 26, 2025.
A device for producing inhalable aerosols through a combined heating and condensation process. The device comprises an oven chamber, a condenser chamber, an air inlet, and an aeration vent. The oven chamber contains a vaporizing medium heated to a pyrolytic temperature, while the condenser chamber contains a vapor that condenses into the aerosol. The aeration vent joins the first airflow path and allows air to join the vapor before condensation, forming a joined path that delivers the aerosol to the user.

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.
