Roughly one month after the voluntary dismissal of its only active case, against Microsoft, Rosebud LMS, Inc. has filed suit against Oracle (1:16-cv-00656). The complaint asserts the most recently issued patent (8,578,280) in a family of three generally related to real-time collaboration over a computer network. The collaborative project management tools provided by Oracle Primavera Prime are accused of meeting the limitations of the ‘280 patent’s claims.
