The PITR (Patent Intelligence & Technology Report) service offers users the ability to create pivot tables of data using the SOLR Solr JSON facet API. This service is a thin layer exposing multi-dimensional reporting on appropriate fields within an IFI CLAIMS Direct specialized SOLR Solr index tst
/pitr/topn
This endpoint returns, at the least, a list of top assignees and corresponding publication counts per year and optionally, monthly within a year. Ranking is based on number of records within the most recent complete year.

Example: Filtering report on distinct criteria
This example will request requests the top 2 assignees who publish in the F16L CPC area (PIPES; JOINTS OR FITTINGS FOR PIPES; SUPPORTS FOR PIPES, CABLES OR PROTECTIVE TUBING; MEANS FOR THERMAL INSULATION IN GENERAL) concentrating on E03B (Water supply installations). Note, the @min parameter is reduced to 1 (default being 10) to satisfy this narrow search field.
