  • uspc_subclass.uspc_mainclass
  • pg_claim.claim_dependent
  • location.location_place_type
  • location.location_num_assignees
  • location.location_num_inventors

Nested Hyperlinked fields​

the nested fields {patent/publication}.uspc_at_issue and patent.wipo have been updated to include links to their respective classification lookup endpoints.
