The PITR (Patent Intelligence & Technology Report) service offers users the ability to create pivot tables of data using the Solr JSON facet API. This service is a thin layer exposing multi-dimensional reporting on appropriate fields within an IFI CLAIMS Direct specialized 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.
| Method(s) | GET | ||
|---|---|---|---|
| Path | /pitr/topn | ||
| Parameter | Values | Description | |
| @n | n=10 | Number of assignees to report, with precedence based on ranking (default: 10) | |
| @min | min=1 | Minimum number of documents worthy of counting (default: 10) | |
| @start | start=YYYY | Beginning year to filter (default: now() - 5 years) | |
| @end | end=YYYY | Ending year to filter (default: current year) | |
| @months | months=1|0 | Add monthly pivot values (default: 0) | |
| @apps | apps=1|0 | Report on pre-grant publications instead of grants (default: 0) | |
| @current | current=1|0 | Use current assignee instead of original (default: 0) | |
| @probable | probable=1|0 | Consider probable assignees as well (default: 0) | |
| @filter | filter=cpc:a61k | Any random Solr search to limit results | |
| @countries | countries=US,EP,DE | Comma-delimited list of countries to report on. Note: These are publication countries, not countries of assignee (default: US) | |
| @pivot | pivot=cpcl3 | Pivot field (any field from the PITR Solr index to generate pivot data for, computed per-assignee) | |
| @pivot.mincount | pivot.mincount=1 | Minimum number of values from pivot considered worthy of counting (default: 1) | |
| @pivot.limit | pivot.limit=5 | Maximum number of values to return, where precedence is given to most frequent values (default: 10) | |
| @pivot.embed | pivot.embed=1|0 | Embed pivot field with years, i.e., break pivot down by both assignee and year rather than just by assignee (default: 0) | |
Example: Top assignee assuming all default values

Example: Filtering report on distinct criteria
This example 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.
