Supported patent fields
Patent documents are structured into well-defined sections, called patent fields. To narrow your patent search results, focus your query statement on specific patent fields.
Alphabetical list of patent field codes
Description of tables
The tables in this topic describe patent fields using the following table columns:
- Patent Field Name. This is the full name of the patent field.
- Patent Field Code. The patent field code is an abbreviation of the full patent field name, used when entering directly into the query box. For example, Jane Smith <IN> AGT will select all patents that have Jane Smith as the Patent Agent. Here, AGT is the patent field code for Patent Agent.
- Text Field (Yes/No). "Yes" or "No" indicates whether a patent field is treated as a Text field in searches. If yes, then this field is targeted when you search All available text fields. Bibliographic patent fields, such as Publication Number and Application Date, are nontext fields.
- Column is included in Patent List results table (Yes/No). "Yes" or "No" indicates if the information for the corresponding patent field can be displayed as a column in the Patent List table. Also see customizing Patent List columns.
- Can be selected from the patent field list (Yes/No). "Yes" or "No" indicates whether you can select a patent field. If you cannot select it from the list, you can always type it directly into the query box as a code.
