Recent setbacks before the Patent Trial and Appeal Board (PTAB) have not dissuaded ChriMar Systems, Inc. and ChriMar Holding Company, LLC (collectively, “ChriMar”) from continuing to file new lawsuits. Last week, the affiliated NPEs sued Polycom (6:19-cv-00015) in the Western District of Texas and USA Vision Systems (3:19-cv-00114) in the Northern District of Texas. Among the four patents asserted across these new complaints (all four against USA Vision; two, against Polycom) are three patents that were successfully challenged in inter partes reviews (IPRs), the invalidations arising from which have been appealed to the Federal Circuit. As it has throughout this campaign, ChriMar accuses the defendants of infringement through the provision of “Power over Ethernet powered devices and/or power sourcing equipment”, both complaints targeting “powered devices” (IP phones for Polycom and IP cameras for USA Vision Systems) but only the USA Vision Systems complaint targeting “power sourcing equipment” (“switches, midspans/injectors, and network video recorders”).
