Use <code>assignments_longform.last_update_date</code> to find current/latest (or first/earliest) date of assignment. Then match with <code>properties.docid</code> on <code>reelno, frameno</code> to find patent application id. With this mapping to granted patents, we can discover the details of the original granted patent. And with the right date and reelno and frameno, we can match to the <code>assignees</code> table and get fine granularity addresses.
