Application and Priority Kind Code Search Fields
Kind codes are not only available for patent numbers, but also for the application and priority numbers. They are searchable in the Application Kind Code (/AK) and Priority Kind Code (/PRK) fields, respectively.
Corresponding to the Patent Information Type (/PIT), the search and display fields Application Information Type (/AIT) and Priority Information Type (/PRAIT) provide information on the application and priority kind codes. There are usually more PRAIT-codes than AIT-codes available for a given patent authority.
The AIT-information is displayed next to the application number, application kind code and application date, the PRAIT-information next to the priority number, priority kind code and priority data. In addition, the entry date for the priority number (/EDPR) is displayed as well as the simple family indicator. This indicator is used by the EPO simple family definition for "active" and "non-active" for the priorities. A priority that does not add technical detail is marked as "non-active" by adding "N" in the priority information. "Active" priorities are marked by "Y".
