What are the search operators used within PatSnap?

Here are some of the search operators you can find within PatSnap. You can also find them here

 

Parentheses

Parentheses are the underlying operator within a query. They can change the overall meaning of a search just by moving their placement. Just like in algebra, they change the order in which the system looks at your query. 

Operator Usage & Funtion Examples
() Parentheses can be used to define the order in which the system combines parts of your search.

vehicle AND (engine OR motor)

 

Basics

The basics are AND, OR, NOT. They allow you to say whether words must be returned, if they are optional, or if you don't want them.

 

Operator Usage & Function Examples
AND

Retrieves patents containing both keywords or criteria.

Either keyword or criteria may appear first

solar AND cell

TTL:computer AND AN:apple

OR

Retrieves patents containing either or both of the keywords or criteria.

battery OR cell

TTL:computer OR IPC: H01L

NOT

Retrieves patents containing the first keyword but not containing the second keyword.

Retrieves patents containing the first criteria but not containing the second criteria.

battery NOT "lead-acid"

AN:apple NOT ABST:screen

 

 

Wildcards

Then you have wildcards. These allow you to use a root word to cover a variety of different options. You can even put a wildcard in another kind of field, like a patent number. For example, writing PN:US* will ensure any publication number that is returned must start with "US...".

Operator Usage & Funtion Examples
*

Can be used to replace a string of characters at the end or in the middle of a word.

Can be used in all text and number fields.

Should be used with stemming OFF.

electr*

EP200*B2

?

Can be used to replace an individual character at the end or in the middle of a word.

Can be used multiple times.
Can be used in all text and number fields.

Should be used with stemming OFF.

gra???ne

US7654???

 

Position Connector

These operators allow you to specify where you want words to appear in relation to each-other. This might be for example when you have two words like "protein" and "analysis". You want to allow variations like "analysis of the protein", or "protein analysis" or "analysis conducted on this protein". In these 3 situations, a proximity of 3 would suffice, therefore a query of protein $W3 analysis would work well. 

Operator Usage & Funtion Examples
$Wn Search words will be within n words of each other, in any order.

data $W2 line

ABST:("solar cell" $W5 silicon)

$PREn Search words will be within n words of each other, in the order specified.

data $PRE2 line

ABST:("solar cell" $PRE5 silicon)

$WS

Search words will appear within 99 words of each other.

display $WS HDMI
