Party Count Table

Return to USPTOAssigneesData.

Table Purpose

The Party Count Table records the number of parties involved in a transaction and specifies the patents involved in the given assignment. The table combines the Assignor and Assignee Count Tables in a more usable format. Additionally, the table illustrates a history of ownership of a patent, which may be considered as an indicator for patent litigation risk in the Little Guy Academic Paper.

Table Variables

Reel and frame give the location on the microfilm files where the particular transaction is recorded. The reel number and frame number are unique to a transaction between the assignee and assignor. The recdate is the date the assignment was recorded by the USPTO. Patent identifies the patent involved in the transaction. Numassignor and numassignee identify how many assignors and assignees were involved in the assignment. The table key is composite consisting of reel, frame, and recdate.
