EXCLUSIVE: PAX warns retailers on Stiiizy vapes
San Francisco-based vape maker PAX sent a cease and desist letter to California distributors and retailers today, warning them that selling certain Stiiizy vape products exposed them to patent infringement claims.
Stiiizy has denied that third parties can be held liable for selling the products.
The letter is the latest development in a long-running intellectual property dispute between the two vape companies. Los Angeles-based Stiiizy is the largest retailer and best-selling vape brand . . .
