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. Patent gives the patent number of the patent involved in a specific transaction. Numassignors is the number of assignors involved in the transaction. The table has a composite key consisting of reel number, frame number, and recdate.
