(Its also important to people subject to FTC investigations to determine whether they are obligated to respond to particular things that purport to be a particular form of administrative subpoena, but, I mean, at the point that your business is subject to an FTC investigation in which they are issuing things that look like administrative subpoenas, you probably ought to be engaging counsel to guide you in that process for more reasons than just "is this something we need to obey", and the substantive law being investigated is going to be a much more complicated thing that the one page order adopting compulsory process for a particular domain of investigations.)
