New suits have been filed against Microsoft (LinkedIn) (1:18-cv-01484) and Quotient Technology (1:18-cv-01485) and come as the deadline to answer or otherwise respond to the complaint in the first case, filed against Twitter earlier this year, has been moved to late October. Infringement allegations focus on the defendants’ use of targeted advertising on their respective platforms.
