Search Operators and Fields Cheat Sheet
Boolean Operators
| AND | All terms must be present | (boat AND propeller) |
| OR | At lest one of the terms is present | (car OR vehicle OR truck) |
| NOT | The term(s) following NOT is excluded | (bass NOT fish) |
Boolean operators can be used to combine or exclude results from multiple search lines in the timeline.
Example, the combination of lines 1-5 of the timeline: (1 OR 2 OR 3) AND 4 NOT 5
Proximity Operators
| nD | Order Non-Specific Proximity Terms are within n spaces of each other, in any order, & n must have a value of 1 or more. | (power 4D battery) |
| nW | Order Specific Proximity Terms are within n spaces of each other, in the order as written, & n must have a value of 1 or more. | (anti 1W aging) |
| nS | Sentence Proximity Terms are within n sentences of each other, in any order, & n must have a value of 1 or more. | (battery 1S charging) ((proportion? 2W solid?) 3S acid?) |
| nP | Paragraph Proximity Terms are within n paragraphs of each other, in any order, & n must have a value of 1 or more. | (cupped 1P jaw) ((insulat* 2w ring?) 1P (alkaline 2D dry)) ((batter* 2D charg*) 4P ( electric* 10D (car OR vehicle))) |
" " (Double Quotes) | Phrase Proximity without Wildcards Searches for exact text, exactly as written within double quotes, however, wildcard operators will not be recognized. Double quotes will prevent search operators and truncation limiters from operating – example, searching for 3D technology | "cell phone" (Results include: cell phone; cell-phone; & cell. Phone) |
' ' (Single quotes) | Phrase Proximity with Wildcards Searches for exact text, exactly as written within single quotes, however, wildcard operators will still be recognized. | '3D goggle?' (Results include: 3D goggle & 3D goggles) |
_
(Under-score) | Optional Space Proximity Text is searched as a single term and as two terms separated by a space or hyphen.
A maximum of 5 underscores may be used per word. | anti_lock (Results include: antilock, anti lock, & anti-lock)
Underscores do not require parenthesis around the words to function properly |
Hyphens are treated as spaces within Quartet.
Same sentence (nS) and same paragraph (nP) operators cannot be stacked. For example ((LAPTOP 1S SCREEN) 1P CHARGER) would not be an accepted input.
Wildcard Operators
| ⁎ | Unlimited Truncation Represents zero or any number of additional characters (letters or numbers). Can be used both at the beginning, middle or end of a word. | deploy⁎ (Results include: deploy, deploys, deployment, & deploying) |
| ? | Optional Single Character Truncation Represents zero to one additional character.
NOTE: Multiple ?s can be stacked to represent multiple characters ??? represents zero to three additional characters | phone? (Results include: phone & phones)
(Results include: computer, computes, computing, computed) |
| # | Single Character Truncation Represents exactly one character that must be present. | analy#e (Results include: analyze & analyse) |
| + | Class Code Stemming Operator Specific for IPC or CPC search fields. The operator returns results for the classification code queried and any of its subordinate classes. | IPC=G01N33/00+ (Results include: G01N33/00 and its subordinate class codes, i.e., G01N33/02 & G01N33/558) |
The asterisk ( * ) operator allows for end truncation. Its meaning and use are the same anywhere within Quartet.
The plus sign ( + ) operator is a unique wildcard that can only be used with classification code searching and is used for searching the hierarchy of a classification schedule. For example, whereas CPC=(G07F19/20*) will search for all classifications that start with G07F19/20, for example G07F19/201-209 will all be captured, but it will miss indented subgroups such as G07F19/21 that would be captured by CPC=(G07F19/20+).
Text Field
| 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 FT is equivalent to TI/AB/DES/CLM | FT=(short_cut AND project) |
| TA | Title and Abstract TA is equivalent to TI/AB | TA=translation |
| TAC | Title, Abstract, and Claims TAC is equivalent to TI/AB/CLM | TAC=(GPU OR processor) |
| None | If no field is given and a default field is not defined in settings, then the default field is FT. | (personal 2W computer) |
Fields may be combined using /, for example, TI/AB/CLM=(personal 2W computer)
Number Fields
| PNUM | Publication Number | PNUM=(US2001023123A1 OR KR20049312*) |
| ANUM | Application Number | ANUM=(US74094800A) |
| FNUM | Family Number (DOCDB Family Number) | FNUM=(3467725 OR 987542?) |
Date Fields
| PUBD | Publication Date | PUBD=2002-01-28 (Results include documents with a publication date of January 10, 2002) |
| APPD | Application Date | APPD<2001-03 (Results include documents with an application date before March 31, 2001) |
| PRID | Priority Date | PRID=<2003 (Results include documents with a priority date on or before December 31, 2003) |
Date formats accepted are YYYY, YYYY-MM, and YYYY-MM-DD
Date fields are searched using =, <, >, =<, and => followed by the desired date.
For "Greater than or equal to" and "Less than or equal to," the order of the equal sign and greater and less than signs are interchangeable.
Ex. PUBD=>2024-02-01 is the same as PUBD>=2024-02-01
Greater than ( > ) and less than (< ) are exclusive of the entered date while greater than or equal to ( => ) and less than or equal to ( =< ) are inclusive of the entered date.
When searching for a range, a colon ( : ) can be inserted between two dates in any of the accepted formats.
Ex. PUBD=2003-01-01:2008-12-31 searches documents published between 2003-01-01 to 2008-12-31.
Country and Kind Code Fields
| CC | Country Code | CC=(CN OR FR) |
| KC | Kind Code | KC=(B1) |
| CKC | Country code & kind code | CKC=(CNB? OR JPB2) |
Classification Fields
| IPC | International Patent Classification Codes | IPC=(C07K16/28 OR C07K16/42) |
| CPC | Cooperative Patent Classification Codes | CPC=(C07K16/2812 OR C07K16/4275) |
| USPC | United States Patent Classification Codes | USPC=(340/2.2) |
| JPFI | Japanese File Index Codes | JPFI=(G06F7/535_520 OR H04B7/26_109@M) |
| JPFT | Japanese F-Term Codes | JPFT=(5B016_FA05) |
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*' |
| IN | Inventors | IN=(Jane 2D Doe) |
Legal Status Fields
| LGL | Legal status Can take both short and long form of legal statuses (see table below) | LGL=Alive LGL=(alive OR rlaps) |
Searchable Legal Status Terms
The legal status terms are searchable in both a long and short form.
| Long form | Short form |
| alive | |

| SPUB: | Single Publication Modifier Terms appear within the same publication. | SPUB:TAC=(personal AND computer) (Results include publications where personal and computer both appear in the Title, Abstract, and/or Claims of the same publication)
SPUB can also be used across multiple fields. Enclose the fields using brackets [ ] SPUB:[CLM=(automobil*) AND PUBD=2020-01-01] (Results include families with automobile in the claims published on January 1, 2020) |
SFLD and SPUB must be combined with at least one of the text fields listed above.
Date Field Modifiers
| .L | Latest Date Searches the most recent date of a date field. Must be combined with a date field. | PUBD.L=2003:2008 (Results include families having a most recent publication date within the range of years from 2003 to 2008) |

| / | Combining two fields Allows the combination of two modified legal status fields | LGL.US/LGL.EP=Alive (Results include all US and EP publications that are live) |
Assignee Field Modifiers
Assignee field modifiers allow for searching original and current assignees. By default, Quartet would search both fields for an assignee match without current or original assignee being specified.

| .O | Original assignee | SPUB:[PA.O=(University 2D California) AND PUBD=2020] (Results include publications originally assigned to the University of California and published in the year 2020) |
Greek Letters
Greek letters may be searched by symbol (β) and by spelled out name (beta), as the system uses them interchangeably.
Examples:
ta='π/2'
ab='α β unsaturated'
ta=("α" and "β")
Symbols
| % | Percent |
| ‰ | Permille |
| ‱ | Permyriad |
| ° | Degree |
