Digital Verification Systems asserts that airSlate infringes its U.S. Patent o. 9,054,860, which covers methods for verifying or authenticating the identify of an entity associated with an electronic file, such as an e-signature. DVS says that airSlate’s Signnow product directly infringes at least claim 1 of the ‘860 patent. DVS appears to be a non-practicing entity, and has filed 23 different lawsuits alleging infringement of this patent, including a separate suit filed the same day in Delaware against dotloop, Inc.
