PDTW150K: A Dataset for Patent Drawing Retrieval

We introduce a new large-scale patent dataset termed PDTW150K for patent drawing retrieval. The dataset contains more than 150,000 patents associated with text metadata and over 850,000 patent drawings. We also provide a set of bounding box positions of individual drawing views to support constructing object detection models. We design some experiments to demonstrate the possible ways of using PDTW150K, including image retrieval, cross-modal retrieval, and object detection tasks. PDTW150K is available for download on GitHub [1].
