I didn't find anything ready to use. This one-liner finds all packages
not provided by Ubuntu (at least it does on my system):

 echo $(dpkg --get-selections|cut -f1|xargs apt-cache show| \
 egrep '^(Package|Origin):'|sed -e's/^\(Package: .*\)/\\n\1/')| \
 grep -v 'Origin: Ubuntu'

It uses the fact that all Ubuntu packages have a field "Origin: Ubuntu"
in their description (as shown by apt-cache show). If your 3rd party has
any uniq field you may do something similar.
