The most important requirement seems to be that an entity must obtain a registered agent in the State of Delaware, which can either be a resident or a business entity that is legally allowed to do business in the state. However, it seems that if the name and address are all that’s required, it could easily be copied from another filing. In this case, the pretender appeared to do little more than copy/paste the registered agent – Daniel Schwieger, a managing director at BlackRock according to his LinkedIn profile – from the legitimate filing.
