Must be legal issues day for me. LOL Q's for US based photographers:

Do you register your rights with the US gov't?

More importantly if you do, have you prevailed in court against an infringement within the last five years?

If anyone here can answer 'yes' to both of the above, I would be interested in speaking with your attorney(s).

TIA

P.S. I'm not really interested in opinions or case history from cases in which the work was not registered.
