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.

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.

Similar Image Search

Similar image search allows you to input image data and search for patents and design publications that have similar images, targeting the drawings disclosed in them.

The system also supports the input of multiple drawings, enabling similar image searches based on a set of six views for designs, or a combination of exterior and internal structure images for patents.

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.
