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
/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.
