BCS Software LLC (d/b/a Bluebonnet Consulting Services & Software) has kept active the litigation campaign that it began in April 2019 by filing suit against Facebook (6:20-cv-00695) in the Western District of Texas over the use of the Apache Zookeeper coordination service on its e-commerce website and platform. The plaintiff asserts a single patent, generally related to a system for using a server to monitor certain client applications and distributed components associated with those applications over a network, acquired as part of a larger deal completed with Intellectual Ventures LLC (IV) in August 2018. Each defendant in the last round in this campaign—Honeywell (Elster), Itron, Toshiba (Landis+Gyr Technologies), and Xylem (Sensus)—appears to have settled with Bluebonnet.
