# Search Fields

The search fields define what is to be searched. Using search fields, the search can be focused to different text fields, limit the search to specific classification areas, and define specific date ranges for the search query.

Search fields can be defined using the Fielded search form and via search commands in the Command Line.

There are 6 different types of search fields, each containing different types of content. The 6 types of search fields are:

-   Text Fields
-   Number Fields
-   Date Fields
-   Country & Kind Codes Fields
-   Classification Fields
-   Party Fields
-   Legal Status Fields

When using the command line, search fields are written on the left-hand side of the query.

Search fields of the same type can be combined together using forward slash ( / ).

**TI/AB/CLM=(personal 2W computer)**

is the same as

 **TI=(personal 2W computer) OR AB=(personal 2W computer) OR CLM=(personal 2W computer)** 

### Text Fields

| **TI** | Title | **TI**\=(personal 2W computer) |
| --- | --- | --- |
| **AB** | Abstract | **AB**\=flow? |
| **DES** | Description | **DES**\=(laptop OR tablet OR notebook) |
| **CLM** | Claims | **CLM**\=(plane 3W (engine OR motor)) |
| **FT** | Full Text<br>FT is equivalent to **TI/AB/DES/CLM** | **FT**\=(short\_cut AND project) |
| **TA** | Title and Abstract<br>TA is equivalent to **TI/AB** | **TA**\=translation |
| **TAC** | Title, Abstract, and Claims<br>TAC is equivalent to **TI/AB/CLM** | **TAC**\=(GPU OR processor) |
| *none* | If no field is given and a default field in not specified in settings, then the default field is **FT**. | (personal 2W computer) |

### Number Fields

| **PNUM** | Publication Number | **PNUM**\=(US2001023123A1 OR KR20049312??) |
| --- | --- | --- |
| **ANUM** | Application Number | **ANUM**\=(US60423099) |
| **FNUM** | Family Number (DOCDB Family Number) | **FNUM**\=(3467725 OR 987542) |

### Date Fields

Date fields are searched using =, <, >, =<, and => followed by the desired date.

Greater than ( > ) and less than (< ) exclude the entered date, while greater than or equal to ( => ) and less than or equal to ( =< ) include the entered date.

| **PUBD** | Publication Date | **PUBD**\=2002-01-28<br>*(Results include documents with a publication date of January 10, 2002)* |
| --- | --- | --- |
| **APPD** | Application Date | **APPD**<2001-03<br>*(Results include documents with an application date before March 31, 2001)* |
| **PRID** | Priority Date | **PRID=<**2003<br>*(Results include documents with a priority date on or before December 31, 2003)* |

Date formats accepted are YYYY, YYYY-MM, and YYYY-MM-DD

When searching for a range, a colon ( : ) can be inserted between two dates in any of the accepted formats.

 Ex. 2003:2008 *includes documents with a publication date in the range of years from 2003-01-01 to 2008-12-31)*

### Country & Kind Codes Fields

| **CC** | Country Code | **CC=**(CN OR FR) |
| --- | --- | --- |
| **KC** | Kind Code | **KC**\=(B1) |
| **CKC** | Country code & kind code | **CKC**\=(CNB? OR JPB2) |

  
 For limiting by dates specifically within a jurisdiction, see either [**SPUB** or **Date** **Field Modifiers**](https://help.quartet.pro/en/article/field-modifiers)

A table of country names and country codes can be found in the [country code table](https://help.quartet.pro/en/article/detailed-patent-coverage).

### Classification Fields

| **IPC** | IPC Classification Codes | **IPC**\=(C07K16/28 OR C07K16/42) |
| --- | --- | --- |
| **CPC** | CPC Classification Codes | **CPC**\=(C07K16/2812 OR C07K16/4275) |

| **JPFT** | Japanese F-Term Codes | **JPFT**\=(5B016\_FA05) |

In addition to using asterisk ( \* ) for truncating a classification code, the plus sign ( + ) can also be used to search a classification code and all subordinate subgroups.

Classification systems can be combined in one command if a code is common to multiple systems. Here are some examples:

-   CPC/IPC=G06F1/03
-   IPC/CPC/JPFI=G06F1/03

### Party Fields

| **PA** | Applicants and assignees | **PA**\='Intel Corp⁎' |
