Inventor State Field (IS)

To query patents where at least one inventor is from a particular state, province, or geographical sub-division, use the IS field code.  Use the two letter postal code when querying the IS field.  

Note - outside of the US and Canada, this field is very sparsely populated.

Examples

  • IS:TX  -->  Finds patents where at least one inventor is from Texas, yee haw!
  • IS:BC -->  Finds patents where at least one inventor is from British Columbia, eh?
