Return to USPTOAssigneesData.

Table Purpose

In a transaction, multiple assignees and assignors may be involved. The Assignee Count Table gives the number of assignees involved in a given assignment. The table was made using the Assignee Table and counting the number of rows per each distinct group of reel number, frame number, and recdate. The table was used to create the Party Count Table.

The recdate is the date the assignment was recorded. Patent gives the patent number of the patent involved in a specific transaction. Numassignees is the number of assignees involved in the transaction. The table has a composite key consisting of reel number, frame number, and recdate.
