Daedalus Blue LLC has filed a District of Delaware complaint against Dropbox (1:24-cv-00998), alleging infringement of three former IBM patents through the provision of various products, including the Dropbox API, Magic Pocket storage system, and Nautilus search engine. At issue are features such as the support for file management and OAuth 2.0. The plaintiff pleads that the asserted patents have been licensed to “many companies”, including Amazon, Oracle, and Dropbox itself, but that “that license expired”.
