Query Syntax (Operator)

Syntax Keywords provide a list of commonly used search syntax. Users can click directly on the syntax that they want to use, followed by their search query. To access this syntax box, simply type any known USPTO search syntax or a / in the search box and it will automatically appear. Click on the Syntax List to see the full list.

Please refer to the respective articles on Quick Search and Advanced Search to learn more about how to use syntax codes in each search type.

Syntax Operator

Example

Explanation

*

SPEC/app*

The * syntax operator is used as a multi-character variable.

In the following example, SPEC/app* will search for any word that begins with "app-," no matter how long the word is.

?

SPEC/app?

The ? Syntax operator is used as a single character variable.

In the following example, SPEC/app? will search for any word that begins with "app-" and will include only words with one additional character.

""

SPEC/"artificial"

The " " syntax operator will search for the exact words/characters enclosed by the quotation marks.

In the following example, SPEC/"artificial" will search for the exact word "artificial."

Note: When using NEAR, do not use quotation marks (“ “) in your query.

()

SPEC/(art OR paint) AND canvas

The ( ) syntax operator denotes the order of precedence when performing a search. Operations within the parentheses will be operated on first.

AND

SPEC/(art AND paint)

The AND syntax operator will search for both keywords on either side of the AND syntax operator. Results will be shown only if the results contain both keywords.

OR

SPEC/(art OR paint)

The OR syntax operator will search for both keywords on either side of the OR syntax operator. Results will be shown only if the results contain only one keyword, or the other keyword, or both keywords.

NOT

SPEC/(art AND NOT paint)

The NOT syntax operator will not search for the keyword after the NOT syntax operator.

In the following example, SPEC/(art AND NOT paint) will search for the word "art" in the description, but it will ignore any results which include both the keyword "art" and the keyword "paint" in the description.

WITH

 

 

AAN/(GOOGLE) WITH AAR/(EYEFLUENCE)

The WITH operator will search for data fields in a single transaction record.

For example, the search for GOOGLE as assignee WITH EYEFLUENCE as the assignor will result in the patents that were directly transferred to GOOGLE from EYEFLUENCE.

Take US8885877B2 as an example:

Q1: AAN/(google) AND AAR/(EYE-COM) AND pn/US8885877B2 → 1 result: wrong result for non-direct transfer

Q2: AAN/(google) WITH AAR/(EYE-COM) AND pn/US8885877B2 → 0 result: correct result for non-direct transfer

Q3: AAN/(google) WITH AAR/(EYEFLUENCE) AND pn/US8885877B2 → 1 result: correct result for direct transfer

The WITH syntax operator is used between assignment data fields (in a pair): Assignment assignee & assignor (AAN, AAR), Licensee & Licensor (LNE, LNO), Pledgee & Pledgor (PGE, PGO).

Note: Do not embrace the query with additional parenthesis, or the WITH syntax operator will not work well, such as (AAN/(GOOGLE)) WITH

AAR/(EYEFLUENCE)→ is the wrong result because a pair of parenthesis “()” separates AAN/ from WITH.

AAN/(GOOGLE) WITH DUR/2017*

AAN/(GOOGLE) WITH AAR/(EYEFLUENCE) WITH DUR/2017*

The DUR syntax keyword will search for transaction records that occurred during a specific time period.

Query Example:
Q4: AAN/(google) AND TRD/2013* AND pn/US8885877B2 → 1 result: wrong result because the transaction record of google as assignee in this patent is not in 2013 but in 2017
Q5: AAN/(google) WITH DUR/2013* AND pn/US8885877B2 → 0 result: correct result
Q6: AAN/(google) WITH DUR/2017* AND pn/US8885877B2 → 1 result: correct result

“ ” (Space)

FCLH/(G06F9 G06F3)

In Syntax Keyword search or Quick Search, space equals to “AND”. You can use space to separate two keywords. In Advanced Search, space will be converted to “OR” or “AND”, depending on your selection.

Title, Abstract, and Claim

 

TAC

 

TAC/(computer notebook)

This will simultaneously search for the patents with the keywords found together in either the title, or the abstract, or the claim sections.

e.g. TAC/(computer notebook) = TTL/(computer AND notebook) OR ABST/(computer AND notebook) OR ACLM/(computer AND notebook)

TAC/computer AND TAC/notebook

This will simultaneously search for the patents with the keywords that must be found in either the title, or the abstract or the claim sections.

e.g. (TTL/computer or ABST/computer or ACLM/computer) AND (TTL/notebook or ABST/notebook or ACLM/notebook)

Abstract and Claim

 

AC

 

AC/(computer notebook)

This will simultaneously search for the patents with the keywords found together in the abstract or the claim sections.

e.g. AC/(computer notebook) = ABST/(computer AND notebook) OR ACLM/(computer AND notebook)

AC/computer AND AC/notebook

This will simultaneously search for the patents with the keywords that must be found in either the abstract or the claim sections.

e.g. AC/computer AND AC/notebook = (ABST/computer or ACLM/computer) AND (ABST/notebook or ACLM/notebook)

Near

NEAR(?)

TAC/((computer notebook tablet phone) NEAR3 (wireless communication transmission))

1. The "?" denotes the range of words within which to search for the keyword pairs. Range is unlimited.

2. The maximum number of keyword pairs to search for is 300.

3. The NEAR operator must be used together with a syntax keyword, as seen in the example.

4. Using two or more consecutive NEAR operators is NOT allowed. For example: TTL/((REFERENCE SIGNAL) NEAR1 device NEAR1 execution) is not allowed.

5. Only up to three NEAR operators (non-consecutive) can be used in a query. For example: TTL/((REFERENCE SIGNAL) NEAR1 device) AND TTL/(device NEAR1 transmitting) AND TTL/(device NEAR1 receiving) is allowed due to a total of three NEAR operators used in three different syntaxes. 

6. While using near operator in search query, quotation("") and asterisk(*) are not supported.

Note: When using NEAR, do not use quotation marks (“ “) in your query.

Notes

IPC (Hierarchy)

ICLH

ICLH/(G01N33/487)

When hierarchy syntax is used, the search results will include the patents in a lower classification as well. For example, a syntax parameter of  ICLH/(G01N33/487) will also search for patents in the subgroup of ICLH/(G01N33/49) because G01N33/49 is under the subgroup of G01N33/487.

More specifically, US20160136639A1 has an IPC of G01N33/49 as opposed to G01N33/487, and it should not be included as a result of ICL/(G01N33/487).  However, the subgroup of G01N33/49 is under G01N33/487, so US20160136639A1 will be included in the results of  ICLH/(G01N33/487).

Note: An asterisk “*” is not necessary when the hierarchy syntax is defined.

Patent Ranking

Data Field

Syntax

Example

Notes

Patent Quality

QRANK

QRANK/3->*

Our model for Quality takes into consideration (based on publication/issue information before it is published) :
- The qualifications and profile of the attorney.
- The qualifications and profile of the examiner.
- The number of the potential prior art.
- The structure of independent and dependent claims.

Each ranking is based on a score calculated using our model:
(5) AAA : Score is in the top 3%
(4) AA : 3% - 10%
(3) A : 10% - 25%
(2) B : 25% - 50%
(1) C : 50% - 75%
(0) D : Below 75%

E.g.: The value of 3 represents "A.” Therefore, 3->* represents values above "A.”

Patent Value

VRANK

VRANK/3->*

Our model for Value takes into consideration (based on publication/issue information before it is published):
- The qualifications and profile of the inventor.
- The qualifications and profile of the applicant.
- The stage of technology lifecycle citation(s).
- Citation(s).
- Pre-grant assignment and licensing.

Each ranking is based on a score calculated using our model:
(5) AAA : Score is in the top 3%
(4) AA : 3% - 10%
(3) A : 10% - 25%
(2) B : 25% - 50%
(1) C : 50% - 75%
(0) D : Below 75%

E..g.: The value of 3 represents "A.” Therefore, 3->* represents values above "A.”

(4) Abandoned: Patents abandoned, withdrawn, or not paid for by applicant or assignee.
(5) Expired: Patents expired because the patent term is due.
(6) Revoked ab initio: Patents invalidated after grant.
(7) PGPub - Granted: Application that has been issued.
(8) Reissued.
(9) PCT End - NP: The PCT stage ended, and the national phase (NP) was entered.
E.g.: The value of 3 represents "Active - Granted".

(Est.) Exp. Date

ESED

ESED/2025*

The estimated expiration date is based on the patent office, patent type, and application/issue date, and is only available for an active patent.

If the estimated expiration date is before the system updating date (e.g. today), or if any abandon event occurs, the estimated expiration date will no longer be searchable and an inactive date of the patent can be found.

If the patent type is “other”, it will be presumed to be “Utility Patent”. Otherwise certain parameter(s) (e.g. kind code) can help determine the date.

We don’t calculate the estimated exp. the date for SPC (Supplementary protection certificate).
