Priority Number Field (PRIN)

To query a patent by its priority number, use the PRIN field code.


  • PRIN:83711 --> Finds all priority numbers with this exact string (except for the year.  In some jurisdictions, such as the example above the year is at the end after the number. In some it is in the front).  
  • PRIN:837* --> Finds all priority numbers starting with 837.  Without the asterisk it would be the same idea as the above search.

Note - The example with the asterisk (PRIN:837*) would pull up the 83711 as well, since 83711 starts with 837.
