Recent history has repeated itself, with M2M Solutions LLC filing a third District of Delaware suit against Amazon (1:20-cv-01781) in the wake of a setbacks in the prior case. The latest complaint asserts the most recent member to issue in the family providing the patents asserted in the other two suits. The inventor-controlled NPE again accuses Amazon of infringement through the provision of its Kindle e-reader “ecosystem”, including the company’s e-readers and the Whispernet content delivery network. Multiple inter partes reviews (IPRs) have halted district court litigation in each of the prior suits, permanently with respect to the first.
