Patent properties have a many-to-one relationship : one patent can have more than one properties.

Note: We are not sure what documents with kind 'X0' say

==== Patent Assignment ====

Every XML file download has some fields associated with it, in addition to a number of patent assignment nodes.

Here are the columns in the table:

* reel_no

* frame_no

* action_key_code

* USPTO_Transaction_Date

* USPTO_Date_Produced

* version

Here is what the XML in a downloaded file looks like:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE us-patent-assignments>

-<us-patent-assignments date-produced="20131101" dtd-version="1.0">

<action-key-code>DA</action-key-code>

-<transaction-date>

</transaction-date>

-<patent-assignments>

+<patent-assignment>

.

</patent-assignments>

</us-patent-assignments>
