For countries which contain IFI Snapshots, IFI calculates current legal status. This includes anticipated expiration dates, information about regulatory extensions, terminal disclaimers, and more. All of this information can be found in the ifi-patent-status container in the XML files, which can be retrieved using the Text service. For more information, see our documentation on the ifi-integrated-content.
How do you calculate the IFI standardized form of the current assignee?
IFI curates the current assignee only for those countries for which Snapshots are available. To calculate current assignee, we use legal event data along with other sources of information. For the US and AU, we receive additional data from the patent offices, which can be found in the assignment history section of the XML. We also do some of our own rules-based work: to identify "individual" (e.g., inventor matches assignee), to standardize the names (e.g., “co” vs “company”), and to create the probable assignee on an application where one isn't present. Our editorial team also creates relationships between names, which are then used in the calculation of the ifi-name-current. For example, when Facebook became Meta Platforms, the change was quickly identified by our editors and the ifi-name-current field was updated to reflect the new name.

The CLAIMS Direct index is created and maintained using Apache SOLR (http://lucene.apache.org/solr/) and hence, based on a schema definition, all of the functionality provided by SOLR is available through CLAIMS Direct, including the entire Apache Lucene query language, result set sorting, facet searching, grouping etc. For more information and examples, see the SOLR Solr Searching Guide.
The basic search syntax used in CLAIMS Direct is SOLR field name:value. For example:
...
Fields available for searching in CLAIMS Direct, along with tips and examples, can be seen in the SOLR Solr Search Fields section. The CLAIMS Direct SOLR index does not store all text. This means that although the entire index is searchable, only certain fields are available for inclusion in a result set. Retrievable fields are marked as "stored" in the SOLR Search Fields tables. You can also find them in the schema where @stored="true", or use the schema method of the Search service to inspect field attributes.

Before you conduct any searches, we recommend that you familiarize yourself with the searching options available in CLAIMS Direct using the SOLR Solr Searching Guide.
