Tinder, widely known for its dating app, is suing a rival called “3nder”, that is focusing on a niche market in the dating world: people who are looking for threesomes. Match Group, the owner of Tinder, is suing for trademark infringement, claiming the app’s name is confusingly similar and gives “unfair advantage”. 3nder is an app for non-monogamous couples and their potential partners; couples who are looking for a threesome. The threesome-app’s founder, Dimo Trifonov, started to fight of Tinder in a bizarre social media offensive. He asked 3inder enthusiasts to post a copy of their socks with the hashtag “TinderSuckMySocks. Meanwhile Trifonov remained realistic: “If I’m realistic, they can bankrupt us. It’s not about that though, it’s about right or wrong. No one has a monopoly on love.” Although Trifonov is right about no one having a monopoly on love, Tinder will stick to the claim it does have a monopoly on the name. And at this point, according to Tinder, two’s company but three’s a crowd.
