===Ptotracking Tables===
The purpose of the ptotracking tables is to track the ownership of patents based on the update date and filing dates of the assignment. These tables can be used to add missing information or track further refined tables such as ptoproperty_patent.
Ptotracking takes the reelno, frameno, and documentid key from the ptoproperty_cleaned table and joins the update dates and recorded dates corresponding to the transactions.
