Changes

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. Assignor gives the name of the assignor in the transaction. The execdate is when the legal motions were executed for the transaction.
