How to search full-text patents
Use the Basic Index (/BI) field to search the full text of the patent document, abstract, and title. You may also restrict your search to the claims only or abstract only.

 

Field	Field Code	Content
Basic Index	/BI (optional)	Single words from the title, abstract, claims, and description fields
Claims	/CLM	Single words from the claims
Abstract	/AB	Single words from the abstract

And, take advantage of the full power of the following proximity operators.

Proximity Operator	Function
(W)	Terms must be adjacent and in the order specified
(A)	Terms must be adjacent, but in any order
(S)	Terms must occur within the same sentence
If you do not include an operator between terms, the (W) operator is assumed.
