This feature analyzes the title, abstract, claims, and CAS indexing for your patent and uses multiple AI-powered algorithm streams to find similar relevant patents and non-patent literature. These documents will all have priority dates before that of your target patent, representing the state of the art before your patent established its priority.

On the home page, click the Prior Art Discovery tile.

Enter at least 200 characters of natural English text (e.g., claims or abstract text) relating to the novelty of the invention or topic of research.

You may edit the Priority Date, which is compared against the non-patent literature's publication date. If you want to see anything that has been published that may be relevant to your text, leave the priority date as 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.

You may also add a structure by clicking the Draw button. Adding a substance (via CAS Draw) 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.

Click the Search button to submit your query.
