Copyright claim after application but before issuance?

I have always understood that registration was an absolute prerequisite for copyright infringement claims by US authors in US courts. A colleague has suggested that there is a trend away from this requirement, and that it might be permissible to file an infringement claim after filing an application but before issuance of a registration. Does anyone agree or know of any authority supporting this? Many thanks. Received on Mon Oct 24 2005 - 22:00:01 GMT
