* 1: How to specify the date field

  • ・ If you want to search for patents from January 1, 2002 to January 1, 2003: "20020101: 20030101"
  • ・ If you want to search for patent documents after January 1, 2002: "20020101:"
  • -If you want to search for patent documents before January 1, 2003: ": 20030101"

Phrase search

When performing an exact match search for a compound word consisting of multiple words (for example, solar panel, Solar Panel) for text fields such as summaries and claims, double-width the compound word. Enter by enclosing the quotation "" ". 

Input example Hit document
"Solar cell panel" × The panel loaded with solar cells. .. .. 
○ Adjacent solar panel. .. .. 
“Solar Panel” × solar roof panel
○ with solar panel …

Search term weighting

Half-width hat "^" for input keywords for text fields such as summaries and claims By entering a numerical value after, you can weight the search term by the numerical value. The weighting for each search term is reflected in the relevance score when sorting by the relevance score when the search results are listed, and the patents that are more relevant to the weighted keyword are ranked higher. 

Input example Explanation
"Solar panel" Loading transport ^ 5 Keyword "transport" weighted 5 Set to double
“solar panel” stack transport ^ 5 Keyword " Set the weight of "transport" to 5 times.

Neighborhood search

Multiple search terms are separated by the specified number of words. It is a function to search for patent documents. For example, if you enter "solar panel", select neighborhood search from the pull-down menu on the right side of the input field, and enter 3 words as the number of words for neighborhood search, you can enter "solar panel", "solar panel", etc. Search for patents where the sun and panel appear within 3 words. It is used when the exact match condition by phrase search is too strict (too narrow) as the search condition. It is not possible to specify the application order for neighborhood search. 

Concept search

Invented in the input field for text fields such as summaries and claims. When you enter a document (summary, claims), a search query associated with that document is automatically generated and searched. It has the same function as the semantic search in Easy search. To perform a concept search, enter the invention document in the input field and select the concept search from the pull-down menu on the right side of the input field. Concept search results are reflected in the relevance score when the search results are listed, and patents with higher relevance are ranked higher. Concept search is a search method suitable for preliminary search performed before the main search using patent classification because it has notational fluctuations peculiar to natural language. 

Wildcard Search

Wild for fields such as patent classifications, summaries, and claims. You can use the card to perform a range search. The question mark "?" Indicates any one character, and the star "*" matches any character string of 0 or more characters. See the input example below. 

Input example Hit document
IPC: B4? Patent classification: B41, B44, etc.
IPC: B * Patent classification: B02, B41, etc.

Creating a patent search expression

You can create a search condition by combining multiple input fields with an operator. The available operators are listed below. If text fields such as summaries and claims are included in the search criteria, they will be reflected in the relevance score when listing the search results, and the more relevant patents will be ranked higher. 

Operator Explanation  Search set
+ It means the logical sum (OR) of each condition. 
* It means the logical product (AND) of each condition. 
- It means that the previous condition does not include the following condition (NOT). 
Notes on creating patent search formulas

Patents It should be noted that in integration, AND search (*) does not automatically take precedence over OR search (+). The search formula is interpreted in order from the left "that is, A + B * C + D * E is interpreted equally as (((A + B) * C) + D) * E". 

For example, the search formula X + Y * Z will be interpreted in order from the left side, and the union of X and Y and the logical product of Z will be obtained as the search result. (See the figure below). In other words, the result is different from the logical sum X + (Y * Z) of X and the logical product of Y and Z. Be careful about what kind of set you are trying to create, and use parentheses appropriately to construct the search formula. 

| X + Y * Z = (X + Y) * Z | X + (Y * Z) | | And the logical sum of it and X |
