Fields of Interest

In order to satisfy the data model, the following fields were of particular interest when extracting the data from the XML files and placing them in tables.

  • type
  • applicationnumber
  • filingdate

For priority, if there is more than 1, we want sequence 01

  • prioritydate
  • prioritycountry (should use ISO country codes - may need a lookup table)
  • prioritypatentnumber

Classification IPC Classification CPC - we only need the main one

CPC is a classification scheme set up by the USPTO and the European Patent Office (EPO). The first classification codes rolled out on November 9, 2012.[1] Full implementation of the CPC classification system occurred on January 2015, at the same time of version 4.5 of the USPTO patent bulk data.[2]

  • Section, Class, Subclass
  • Main Group, Subgroup

Classification National: Note that the one below comes out to 2/2.11 (http://www.google.com/patents/US8925112#classifications)

  • Country
  • Class

Title of the patent Number of Claims Primary examiner:

  • FirstName, LastName, Department

PCT/Regional Patent Number:

Patent Citations (we need all of them):

  • CitingPatentNumber (from the patent)
  • CitingPatentCountry (from the patent)
  • CitedPatentNumber
  • CitedPatentCountry

For non-patent references, we are just going to count them:

  • NoNonPatRefs
  • PatentNumber (and country) to build a key
  • We need a standard name and address object for each inventor

Assignees

  • PatentNumber (and country) to build a key
  • We need a "standard" name and address object for each assignee
