Bumble, launched in 2014, has become a fierce competitor to Tinder. The move has always been the differentiating factor between Tinder and competitor Bumble.
"This case is not about feminism or a business marketed based on feminist themes; Match applauds Bumble's efforts at empowering women, both in its app and offline, and Match cares deeply both about its women users and about women's issues generally". The service uses a similar swipe-to-match feature as Tinder, but requires women to send the first message.
The company that owns Tinder says this is the first time it's enforcing its patents on swiping and double opt-ins for dating matches on Tinder.
Tinder and Bumble have had a complicated history. Wolfe had earlier sued Tinder alleging sexual harassment. The case was eventually settled. The lawsuit from Tinder accuses former employees Chris Gulczynski and Sarah Mick, who now work for Bumble, of copying design elements.
Gulczynski and Mick are at the center of the stolen secret allegations. In addition, they took the idea for a feature that allows users to go back if they accidentally skipped someone while going through potential matches. The suit also claims that Gulczynski and Mick implemented photo messaging at Bumble after Gulczynski had designed the feature for Tinder.
In a statement, a Match Group spokesperson said the company is "committed to protecting the intellectual property and proprietary data that defines our business".
Match also claimed that Bumble has infringed United States design patent D798,314, which covers the aesthetic element relating to Tinder's swiping of cards.
The lawsuit comes amid reports that Match is actually trying to buy Bumble.
Most recently, Match made an offer to buy Bumble last summer for $450 million, according to TechCrunch. Last Friday, Recode quoted sources saying Match was still interested in acquiring Bumble.
Match Group said it doesn't comment on mergers and acquisitions speculation.
