The case of the day is Elsevier, Inc. v. Chew (S.D.N.Y. 2018). Elsevier, a publisher, sued twenty unknown defendants, alleging they were infringing its copyright by selling counterfeit textbooks on eBay. By way of subpoenas to eBay and PayPal, Elsevier was able to obtain the names and email addresses of the defendants, though not their physical addresses. Some of the defendants operated in Malaysia, some in China. Elsevier moved for leave to serve process by email under FRCP 4(f)(3). They proposed using Re@dNotify, a service that purports to be able to prove when an email recipient has read an email.
