OBSERVER - Aug 5 - David Yarus, founder of JSwipe, launched a crowdfunding campaign on Indiegogo to raise $180K to protect itself against a suit by Spark Networks, the parent company of JDate. Supporters have committed $12K so far. JDate claims that JSwipe has violated its trademark, using the letter J. It also claims that JSwipe has violated its patent on an “apparatus for detection of reciprocal interests or feelings and subsequent notification.” JSwipe is a ten month-old startup, similar to Tinder. "Our case against JSwipe is about their theft of our technology and their brazen attempt to build a business on the back of JDate,” said Michael Egan, CEO of Spark Networks.
