Depends how much change has been made, an Apache header should not added and the the original license keep unless there have been significant changes.

But I think you would agrees the patch file contains code that belongs to the original copyright owners and those license need be be respected. I just notice the patch actually removes the original license which is probably not a valid thing to do. (see above) Why not be on the safe side and mention it the source LICENSE (as there's no harm done if it ever turns out they were not needed)? By not mentioning them it’s probably a licensing error. Unless you really think it worth a delay in asking asking legal discuss for clarification. Thanks, Justin 1. http://www.apache.org/legal/src-headers.html#3party
