In order to restructure the current patent dataset, the data requires rigorous cleaning. The primary areas for improvement are:

1. Clean ptoassignment table to unique keys.
2. Clean ptoproperties to remove nonutility patents. The patent numbers currently include:
  • 7 digit patent numbers
  • application numbers
  • unknown numbers that cannot be matched to patent numbers in the patent table
20090108066
20100007288
20090108066
20100110022
  • Design and Reissue patents ('%D%' or '%RE%')
  • alphanumeric character strings
3. Restructure address information in ptoassignee table to extract meaningful information
4. Verify that cleaned patent documentids correspond to patent numbers or application numbers in the patent table
5. Restructure address information in ptoassignment table
6. Transform structure of the dataset
