Redesign Assignment and Patent Database (view source)

The paper mentions that there will errors in patent number stored in DOCUMENT_INFO under grant_doc_num so a separate table called DOCUMENT_INFO_ADMIN was constructed to determine how prevalent errors were. They queried the patent number from for the appno_doc_num from administrative data. The "appno_doc_num" is the Application Document USPTO number from DOCUMENT_INFO. On further investigation into the paper, it became clear that "administrative data" refers to internal USPTO data that was available to the authors of the paper, but that we might not have. However, in 99% of cases the grant_doc_num and the queried patent number based on the appno_doc_num were the same, so we can probably rely on grant_doc
Also in the paper, they mentioned the Assignments on the Web for Patents (AOTW-P), a searchable database of individual USPTO assignment records keyed on reel-frame identification, patent number, and assignor or assignee name (https://assignment.uspto.gov/patent/index.html#/patent/search). Obviously it would not be possible to individually use this tool to query all the patent numbers, but if it would be possible to write a script to somehow query each patent number using the rf_id and parse the response, this could potentially be very usefulto check the patent numbers, but might not be any more accurate than what will already be in DOCUMENT_INFO.
