The National Academy of Sciences' 2005 report "Asking the Right Questions About Electronic Voting," stated:
"A vendor may uncover a potentially problematic issue in software that has been previously certified and address the issue in a program patch... [A patch] is any change to a software program."
Ellen Theisen, CEO of the Vote-PAD Company, stated in her May 12, 2004 paper "Voter-Verified Paper Ballots Are Not Enough to Fix DRE Problems," available at the VotersUnite! website:
"'Patch' is an innocuous word, like 'glitch.' But a patch means that the code has been changed to fix a bug."
