⚖️ Puffco vs. Carta: A Vaporizer Lawsuit That Shaped the Industry

In the competitive world of portable vaporizers, innovation often walks a fine line with imitation. That line was tested in a high-profile legal battle between Puffco and SHO Products, the makers of the Carta vaporizer. The dispute centered on Puffco’s U.S. Patent No. 10,517,334, which covers key features of its flagship device, the Puffco Peak.

🔍 The Lawsuit at a Glance

Puffco filed suit against SHO Products and MasterMinded Inc., alleging that the Carta OG, Carta 2, and KandyPens Oura infringed on its patented vaporizer design. The patent specifically protects aspects of a portable electronic vaporizing device, including its airflow system and snap-on carb cap.

The defendants countered by challenging the validity of the patent. However, in April 2024, the court ruled in favor of Puffco, confirming infringement on multiple claims and issuing a permanent injunction. This barred the sale and import of the infringing devices in the U.S., solidifying Puffco’s position as a leader in vaporizer innovation.

🛠️ How Carta Sport Dodged the Patent

Rather than exit the market, Focus V (makers of Carta) pivoted with a redesigned device: the Carta Sport. This model was engineered to avoid the specific features protected by Puffco’s patent while still delivering a high-performance experience.

Key changes include:

• Bubble Carb Cap: Replacing the original “Control Stick” with a bubble-style carb cap that offers directional airflow without mimicking Puffco’s snap-on design.
• Removable Silicone Airpath: The Carta Connect system introduces a modular airpath that differs from Puffco’s integrated setup.
• Upgraded Electronics: Enhanced microchips and battery systems support Bluetooth connectivity and compatibility with Intelli-Core™ atomizers—distinct from Puffco’s heating technology.
• Legal Design Adjustments: Focus V’s engineers carefully reworked the Carta Sport’s design to steer clear of any patent-infringing elements, ensuring compliance while maintaining user appeal.

🚀 What This Means for the Industry

The Puffco vs. Carta case is a wake-up call for vaporizer brands: innovation must be both bold and legally sound. It also shows how smart design pivots—like those seen in the Carta Sport—can keep a brand competitive even after a legal setback.

For entrepreneurs and marketers in the cannabis accessories space, this case underscores the importance of IP awareness, agile product development, and the value of distinctive design.
