I was only addressing one point from all the discussion above... just the issue of whether certain types of files would be copywritable (and the lack of necessity for P5 to address this in the EULA at all). You're right, I did not touch on the issue of ownership of a file FORMAT. That's because I don't feel I know enough about the issue to comment and am therefore following this threads with interest. But both topics are discussed above, so nyah! ;) Honestly, I am concerned about the File format rights claimed, but I think CL is largely trying to piss up a rope because they didn't say this in previous versions and the file formats are unchanged. I think that if they went to court on the issue, they'd be told they lost right to claim ownership by waiting far too long to do it. If you own P4 and do not upgrade and write programs that create or modify CR2s, you can not be bound to the P5 EULA. It's a contract you didn't "sign". Likewise, you could say, oh, it was a P4 CR2 that was reverse engineered because CL didn't claim ownership of those, and they can not legally retroactively apply a rule. And it's not my fault the file format has not changed from the previous unprotected one. Phoenix
