Bumble, the popular dating app, announced its decision to “swipe left” on Tinder’s parent company, Match Group, by taking out a full-page New York Times ad Tuesday morning. The ad and accompanying blog post were prompted by the patent infringement lawsuit filed against them by Match Group on Friday.

The lawsuit claims that Bumble copied key features of the Tinder app in its design, including the swipe-left or swipe-right functionality, cards, blind opt-in features, and other UI displays. Bumble CEO Whitney Herd is no stranger to lawsuits involved the dating app. Her position as co-founder and VP of Marketing at Tinder ended in 2014 with Herd suing the company for sexual harassment and discrimination –- the case was later settled out of court.

Match Group, the owner of Tinder, OkCupid, Match.com and Plenty of Fish, made an offer to acquire Bumble for $450 million last year.

Bumble’s ad states that they “aren’t scared of aggressive corporate culture,” and that scare-tactics like Match Group’s aggressive lawsuit motivate them to work harder. They state that they will “always swipe right for empowered moves, and left on attempts to disempower us.”

In a blog post response, Bumble denounced the “bullying” tactics and proclaimed that their dating app will never be sold to Match Group, “no matter the price tag.”

We swipe left on you. We swipe left on your multiple attempts to buy us,copy us, and, now, to intimidate us. We’ll never be yours. No matter the price tag, we’ll never compromise our values. We swipe left on your attempted scare tactics, and on these endless games. We swipe left on your assumption that a baseless lawsuit would intimidate us. Given your enduring interest in our company, we expected you to know us a bit better by now. We — a woman-founded, women-led company — aren’t scared of aggressive corporate culture. That’s what we call bullying, and we swipe left on bullies.

The lawsuit and Bumble’s heated response come less than a year after Match Group reportedly offered to acquire the dating app at a valuation north of a billion dollars.
