The day after EveryMD LLC’s short-lived case against LinkedIn was dismissed with prejudice, the NPE filed a new case against Airbnb (2:16-cv-03729). EveryMD’s complaint asserts two patents (8,499,047; 8,504,631) from a family of five that generally concern sending messages through an intermediary that may or may not be online. Each of these patents has been asserted by EveryMD in prior cases in its sole litigation campaign; past defendants include Alphabet (Google), eBay, Facebook, and Twitter. With the exception of this week’s case against Airbnb, all of the NPE’s cases have been dismissed, most following apparent settlements.
