Exploratory Search is an AI-enhanced search option that helps users find the most relevant patent and non-patent literature references without the use of traditional STN search commands. This new feature set is designed to complement (not replace) the robust search capabilities available in STNext.

Using the Search

Search Text

Enter at least 200 characters of natural English text (not Boolean operators) relating to the novelty of your invention or topic of research. For best results, provide a clear, concise description and avoid the use of abbreviations and short-hand notation.

Notes:

  • The text entry field accepts up to 10,000 characters.
  • All user-entered text is handled as plain text.

Priority Date

If you want to see anything that has been published that may be relevant to your text, leave the Priority Date at the current day default. If you only want to see results before a certain date, set the priority date accordingly (documents newer than your priority date will not be shown). The system will also use this date as one of many factors in determining result relevance; documents with priority dates close to the priority date that you designate may be determined to be of higher relevance than older documents.

Adding a Substance Structure (Additional Criteria to Emphasize)

Add an optional substance structure from My Files > Structures, or draw your own. Note: Adding a substance (via the Structure Editor tool) to include with your search text provides input to the system to find and boost the relevance of documents that involve your substance and/or substances that are structurally similar to your structure of emphasis.
