Anyone have a current address or other contact to serve a grand jury subpoena on hotels.com or Expedia?

Every corporation doing business in Texas should have a registered agent for service of civil process on file with the secretary of states office. Not sure if that applies to a subpoena but don't know why it wouldn't. Probably a fee to search the SOS website but might be able to call them in your capacity as an investigator, LE etc., and get it.
