Patent licensing company Kaddan Entertainment, Inc. has revived its sole litigation campaign with a new case against LG Electronics (LGE) (4:18-cv-00596). Kaddan accuses the company of infringing four patents through the provision of various LG Tone neckband headphones, each of which allows its earbuds to be secured magnetically to the device’s body. This is the plaintiff’s second lawsuit to date; its 2014 case against Monster (1:14-cv-05203), targeting magnetic earbuds that snap directly together, ended in an apparent settlement after less than a year of relatively uneventful litigation. Beyond that litigation, Kaddan has also licensed its magnetic earbud technology under the trademarked brand name “Quik Clik”, with licensed products currently sold by Harman subsidiary JBL.
