For your business achievement.

Patentfield is the Patents Search and Analysis Platform is combined the Advenced Search, Data Visualization, AI Functions, etc. It's not only for Searching, it also has AI Semantic Search and AI classifications for screening patents faster.

The AI Semantic Search

For Similar Patents

AI has been learning word meanings from over 10 million data patents in order to find similar patents.

If you search for "Solar panel", you will find similar patents data which include "Photovoltaic power generation panel" etc.

Semantic Score

By scoring in descending order of similarity from any natural documents or specific documents you want to find, you can investigate immediately from the patent literature that is close to the technology you are looking for without preparing teacher data etc.

You can easily conduct surveys efficiently from nearby content technologies without altering the search results by inputting any sentences or numbers in the Advanced Search.

AI Classification

Make It Faster

AI sorts out patents based on Teacher Data quickly.

The AI learns over 10,000 teacher data in few seconds. It predicts and sorts 100,000 patents immediately.

Supervised AI Score

You can set binary or multiclass supervised labels with natural sentences or patent application numbers of the technology you want to search in the AI score settings. We can learn 10K supervised data with supervised machine learning within a few seconds to 10 seconds at high speed. With your own model machine-learned, you can predict up to 100K search results within a few seconds and add it to the score.

You can conduct research more efficiently by supervised learning. In addition, since it is possible to predict arbitrary search results, you can easily find out newly interesting patents.

Data Management

For Workflow

By signing up, you can use various data management functionalities such as pdf bulk download of original JPO PDF, Excel export of search result/aggregate result, save search conditions on our server, and email alerts.

PDF Bulk Download

You can download up to 100 original PDFs of publications from JPO in the search results. (JPO publications published since 1971 / USPTO publications published since 1976)

The download process is executed in the background on our server. To confirm process and download bulk files from My Account.

Excel/Graph exporting

Search results can be exported via an Excel file (up to 1000 records at once).

The Excel file includes not only search results but also aggregate results data. (Sample: )

Save search conditions

The complex search and analysis conditions set in Advanced Search can be saved Advanced Search to our server.

The search conditions can be named, and can be organized according to the application, by case or by customer.

Default settings can be used to customize the display count, sorting condition, scoring condition, etc.

Email Alert

Users can be notified weekly by email of search results based on the saved search conditions when new results are published or updated.

E-mail will be sent every Friday morning in JST(※) after updated the published/granted publications and the prosecution/appeal histories.

※Email notifications may be delayed due to update processing status.
