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.

Current Problems

The patentid table has many entries that do not consist of only integers.

SELECT COUNT(*) FROM patentid WHERE patentid ~ '[A-Z]'; 
 count  
-------
775982

SELECT COUNT(*) FROM patentid WHERE patentid ~ '[^A-Z]';
 count   
--------
27294418

There are duplicate entries for certain judges that may be dropped once data on patent litigation has been added.
