==Data Cleanup Progress==
===Patent Number Cleanup===
The goal is to only have assignment records on utility patents. The patents in ptoproperty include alphanumerics which represent reissue and design patents as well as mistakes in the data input. Additionally, the documentids include application numbers or ids and publication numbers. The ptoproperty table stores the patent ids as character strings.
SELECT COUNT(*) FROM ptoproperty_cleaned;
--27266638
Next, the Reissue and Design patents were removed.
