Does the second schematic sheet title block need all the same information as the first sheet. To me it seems kind of redundant to keep the signoffs and proprietary statement...
Absolutely. All information should be on all sheets. Consider that the schematic could be printed, and the sheets separated. A copyright notice on page one is not much use when someone copies page two.
Put it another way, why not have all info on all sheets?
If it's space - you're already doing it wrong.
