Boolean Operators

AND	All terms must be present	boat AND propeller
OR	At least 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

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)

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)

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?)

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)

comput???

(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 the user has not specified a default field in their 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

Searchable Legal Status Terms

The legal status terms are searchable in both a long and short form.

Long form	Short form
alive
dead
pending	pend

lapsed	laps
recentlylapsed	rlaps
longlapsed	llaps
revoked	rev
expired	exp

Examples:

LGL=Alive

Text Field Modifiers

SFLD:

Single Field Modifier

Terms appear within the same field within a family.

SFLD:TAC=(personal AND computer)

(Results include families where personal and computer both appear in the Title, Abstract, or Claims)

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

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)

ta=("α" and "β")

Symbols

%	Percent
‰	Permille
‱	Permyriad
°	Degree
