Conveyance Table

Return to USPTOAssigneesData.

Table Purpose

Each assignment includes conveyance text describing what type of transaction occurred. The assignment records and documents are exchanged with the USPTO typically through a company representative or an attorney representing the company involved. The Conveyance Table records the both the type of transaction that occurred and the correspondent in charge of the assignment records. The conveyance text may be extremely relevant in tracking a firm's interactions with other IP firms, the historical context for a firm's asserted entity status with the UPSTO, and potentially the effects of patent case settlements and resolutions.

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. The recdate is when the assignment was recorded in the USPTO. Lastupdatedate is the last date the assignment record was updated. If the assignment record has been erased from the assignment database, the purge indicator will have a Y entry. The corrname is the person or organization dealing with the documentation of the assignment. Typically, the correspondent will be part of a firm involved in the transaction or an attorney. The correspondent's address is given in the four subsequent columns. The conveyance text describes what kind of transaction occurred in the assignment, meaning in what form the intellectual property was assigned. There are 162,613 distinct types of conveyance text included in the table.

SELECT COUNT(DISTINCT conveyancetext) FROM conveyance;
                     count  
                    -------
                    162613

The entries will often only vary a little given the addition of "(SEE DOCUMENT FOR DETAILS)" at the end of entries. The top ten entries are:

• Assignment of Assignors Interest (See document for details).
• Assignment of Assignors Interest.
• Change of Name (See document for details).
• Confirmatory License (See document for details).
• Merger (See document for details).
• Security Agreement.
