Poppers are little bottles of liquid you sniff (not drink). People use them to feel relaxed, excited, or just a bit looser when partying or during sex. The trademark was registered for, among other things, chemical preparations and scents that stimulate sexual activity, not intended for medical or pharmaceutical use (for products in classes 1 and 3). I suspect a competitor tried to torpedo the brand, as a procedure was started claiming the trademark wasn’t being used genuinely. Funline provided plenty of evidence of use for poppers. However, poppers actually fall under class 5 (medical and pharmaceutical products), and the trademark wasn’t registered for that. Result: the JUNGLE PREMIUM trademark was cancelled. Lesson learned: always have your trademarks filed by a certified trademark attorney. They’re trained for years to know how to file the best claim. Don’t risk ending up empty-handed.
