Easy discovery of suitable patents using semantic search and 100+ searchable fields inlcluding prosecution/appeal histories in Japan, making full use of machine learning technology without the need for expert knowledge.
Search results contain aggregate results of patent attribute information such as applicants and patent classifications on sidebar, and you can easily add filter conditions simply by clicking on them.
You can search with logical set operations as with general search engines.
In the main search field, you can :
AND search by separating the queries with a space such as 'neural network',
OR search by connecting "OR" between queries such as 'neural OR network',
NOT search by connecting "-" between queries such as 'neural -network',
Phrease search by enclosing multiple words separated by space with double quotation marks(") such as '"neural network"'.
In Advanced Search's Filters(Details), by default the space separator operates as the OR search (including any). You can change the behavior of the space separator with the right select box.
You can search documents where multiple words appear close together.
In the main search field, you can
Near search by inputting '*Nx"word1 word2 ... word N"' (x is numerical value) such as '*N5"neural network"'.
You can filter by how many additional words can appear in the search results.
In Advanced Search's Filters(Details),
you can Near search
to select "Including within x" of the right select box and enter a numerical value in the x field and input multiple words separated by blank.
Near search can not be used for any search fields that do not support near search, such as application number and filing date.
Fuzzy search can return results where some characters may be different from the search query. For example, if you enter "GOOGLE" for applicants of US, you can also see results with misspellings such as GOOGEL OR GOOGOLE.
Fuzzy search is available for some search fields in the Advanced Search's Filters(Details). adding a filter condition, to select "Fuzzy match" of the right select box and entering a numerical value up to 5 in the x field you can hit attributes whose changed within x characters from search query.
Similarity search with the potential semantic meaning based on machine learning technology. For example, the keywords "SOLAR PANELS" and "PHOTOVOLTAIC PANELS" have similar potential semantic meanings. Searching with a keyword "SOLAR PANELS" or sentence including the keyword will return similar concept documents including "SOLAR PANELS" or "PHOTOVOLTAIC PANELS".
By specifying the patent or publication number, it is possible to search similar concept documents. You can also semantic search by clicking the link of the search result list or details page.
If your search is not returning relevant results, please input exact keywords appearing in documents to second field of Advanced Search.
You can extract similar concept keywords by clicking button in Advanced Search after inputting the keyword in the main search field.
When you click on the similar keyword, the selected keyword is added to the end of the main search field.
