Field Code Guide

TEXT FIELDS

Notes: 

1. You can enhance your design patent search by utilizing both wildcard (*) and proximity operators (w/wd/ws/wp) in your query. Wildcards help capture variations of a word, while proximity operators allow you to search for terms that are located within a specified range of each other, ensuring a more precise and comprehensive result. You can specify a number after *. For example *1 will match for 0 or 1 characters.
2. Wildcard (?) only stands for exactly one character. You can use this wildcard to cover word variations. For example t?re will search for tyre OR tire 
3. You can use underscore (_) to match all three types of combinations between words – single word, hyphenated word or exact match. So jet_engine will match jetengine, jet engine and jet-engine. 
4. Wildcard does not work within Double quotes. So “electric chair*” will give zero results. Since the default operator in PatSeer is an exact match, simply search for (electric chair*) to get the desired result set.
5. * VAC is an AI generated field that will give contextually similar design patents to the text entered. 
6. PatSeer Search system has no stopwords. To search for words AND, OR, NOT or syntax related words such as W, WD, WS, WP you can include them in double-quotes. 

      For example: T:"bottle and cap "  

                           INV:"john w" 

Using these words outside double-quote will make the system treat them as operators and not search terms.

DATES AND YEARS

Notes: 

In Field Search, there is a From - To date Range option for Application and Publication dates. You can enter only a year or year with month and date. 

• In the “From” field 2021 converts to 2021-01-01 and 2021-09 converts to 2021-09-01. So the first day in the year or the first day in the month is automatically assumed. 
• In the “To” field 2021 converts to 2021-12-31 and 2021-09 converts to 2021-09-30. So the last day in the year or the month is automatically assumed 

To search for an exact date, enter the same values in both From and To fields. 

Using BEG and NOW in date range 

You can use BEG and NOW in a range query as shown in the example below: 

APD:[2020-06-01 TO NOW] - matches all dates from June 1, 2020 to current date. 

APD:[BEG TO 2017-12-31] – matches all dates up to Dec 31, 2017 (including Dec 31, 2017) 

Using the Year fields 

Each date field also has a corresponding year field. So Application Date APD has APY, Publication Date PBD has PBY. So you can use these fields if you want to search for a year range. It’s simpler and avoids any confusion. So: 

APY:[2013 TO 2023] : matches all application dates in years 2013 to 2023 (both years included)

You cannot use NOW or BEG in the year fields

PARTIES (ASSIGNEES, INVENTORS, ATTORNEYS)

CLASSIFICATION

CITATIONS

Note: Using a kind code is optional when searching in citation fields.

COUNTRIES AND NUMBERS

OTHER

Notes:

1. Fields present in Other section (having *) from Shape to Components are AI generated. Searching in these fields will enhance design patent search by focusing on specific attributes. These codes enable more detailed and precise searches beyond traditional classification systems.
2. LSC or Current Legal Status is the current status of the record as calculated by PatSeer when going through its details. Every time new legal status data is received the LSC gets updated for all applicable records. For each record LSC can only one of the following values:
