text: I thought it prudent to invest approx. US$1000 and register "EnronOnline" as 
  a trademark in Australia. My preference would be for Enron Australia Pty. 
  Ltd. to  register the trademark. But I note that the Enron logo is registered 
  in the name of Enron Corp. I assume this was done prior to the incorporation 
  of any Enron companies in Australia. Do you know of any practice (I couldn't 
  find a policy) to register trademarks in any particular Enron body corporate?
