Design Patent Image Classification Challenge

1. The purpose and significance of the competition

Design patent search can help users find the design patent they need based on requirements. Especially when companies are developing new products, they can avoid duplication of development through design patent search. At the same time, they must also use patent search to circumvent essential patents. An important part of patent search includes the classification of images. Therefore, strengthen the classification of design patent images is the research of intelligent retrieval system, which has strong practical value in the field of intellectual property rights. At present, the research on image classification and retrieval is developing rapidly, and there are many domestic and foreign researchers, and the article methods are constantly emerging. However, most of the research is mainly focused on the algorithm level, trying to solve the problems of low accuracy, recall and slow query speed faced in image classification and retrieval models. However, there is currently a lack of publicly available data on design patents, because patent data are generally held by official agencies and cannot be easily obtained by people.
In view of the above situation, this competition will provide a benchmark for the performance evaluation of the classification of clothing design patent images for the general public. The benchmark can be used to test and evaluate classification-related algorithms as a benchmark for public standards. At the same time, it can also promote research in the field of intellectual property and promote the application of artificial intelligence and big data technology in the field of intellectual property.

Organizer: Guangdong Provincial Key Laboratory of Intellectual Property and Big Data
Guidance: The 4th Chinese Conference on Pattern Recognition and Computer Vision (PRCV 2021)

3. Task introduction

The main task of this competition is to classify the design patent images. The participating teams design related algorithms according to the characteristics of the design patent images, use the clothing design patent image data set given by the organizer for model training, and finally the F1-score is used as an evaluation index to measure the performance of the participating team's algorithm model.
