I can't believe that you have not been asked to provide annual review information, but if the terms of your proposal do not require annual reviews then the IP is probably acting appropriately.
Read through your documents to be sure, as if you are required to produce information the onus is on you to produce rather than your IP to chase up. And it is probably worth a call, as Nicola has suggested, to your IP to find out why they are not asking for this. Presumably you have been receiving copies of the IP's annual reports?
