Vaporizer Battle Ends with NJOY’s Final Victory at UPC Court of Appeal

The long-standing patent dispute between NJOY, VMR, and Juul Labs over vaping technology has reached its conclusion with a significant ruling from the Unified Patent Court (UPC) Court of Appeal. At the end of 2025, the court dismissed VMR’s appeal and revoked one of the key patents in question, EP 3 456 214, in its entirety. This decision marks a pivotal moment in the vaping industry’s intellectual property landscape, as the contested patent had previously survived opposition proceedings at the European Patent Office (EPO).

The patent EP 3 456 214 was central to VMR’s claims against NJOY and Juul Labs, as it covered critical aspects of vaporizer technology. Despite surviving initial challenges at the EPO, the UPC Court of Appeal found grounds to revoke the patent after a thorough review. This revocation effectively removes a significant barrier for NJOY, allowing the company to continue its operations without the looming threat of infringement claims based on this patent.

The legal battle between these companies highlights the complexities of patent enforcement in the rapidly evolving vaping sector. VMR’s initial success in obtaining and defending the patent had positioned it as a strong player in asserting control over certain vaping technologies. However, the final ruling underscores the importance of rigorous patent examination and the potential for appellate courts to overturn prior decisions when warranted.

For NJOY, the court’s decision is a major win that not only resolves a protracted dispute but also reinforces its position in the market. The ruling may also influence future patent strategies among vaping companies, encouraging more robust patent filings and defenses. Moreover, the case exemplifies the role of the UPC in harmonizing patent litigation across Europe, providing a centralized forum for resolving such disputes efficiently.

The outcome also sends a message to other players in the vaping industry about the challenges of securing and defending patents in a highly competitive and innovative field. As companies continue to develop new technologies, the balance between protecting intellectual property and fostering competition remains delicate. This case serves as a reminder that patent rights are subject to ongoing scrutiny and can be overturned if they do not meet legal standards.

In summary, the revocation of VMR’s patent by the UPC Court of Appeal concludes a significant chapter in vaping technology litigation. NJOY’s victory not only removes a legal obstacle but also highlights the dynamic nature of patent law in emerging industries. Stakeholders in the vaping market will likely watch closely for how this precedent influences future patent disputes and technological innovation.
