收藏资源简介:
PatSnap Design FTO Bench 是一个用于评估设计专利自由实施(FTO)检索系统的基准数据集,专注于跨模态图像搜索。该数据集基于真实专利无效程序构建,包含91个样本,覆盖中国(CN)管辖区域。每个样本提供一个查询产品图像(或设计专利图)以及一组真实标注的目标设计专利,这些专利通过专利无效程序被确认为构成侵权风险。数据模态为PNG图像(产品照片与专利线条图/照片),图像目录结构为data/image/<管辖区域>/<类别>/<子类>/<专利号>/<文件>.png。真实标注是基于专利无效程序确认的侵权等效专利对。数据集覆盖所有26个一级洛迦诺(Locarno)分类类别,采用CC BY-NC 4.0许可证,仅用于研究和非商业评估目的。该基准旨在评估检索系统在返回相关设计专利以支持FTO审查方面的性能,使用命中率@K和PRES@N等指标进行评分。
PatSnap Design FTO Bench is a benchmark dataset for evaluating design patent freedom to operate (FTO) retrieval systems, with a focus on cross-modal image search. This dataset is constructed based on real patent invalidation proceedings, containing 91 samples and covering the jurisdiction of China (CN). Each sample provides a query product image (or design patent drawing) and a set of ground-truth target design patents, which have been confirmed to pose infringement risks through patent invalidation proceedings. The data modality consists of PNG images (product photos and patent line drawings/photos), and the image directory structure follows the pattern: data/image/<jurisdiction>/<category>/<subcategory>/<patent_number>/<file_name>.png. The ground-truth annotations are pairs of infringing equivalent patents confirmed via patent invalidation proceedings. The dataset covers all 26 top-level Locarno classification categories, is licensed under CC BY-NC 4.0, and is intended solely for research and non-commercial evaluation purposes. This benchmark aims to evaluate the performance of retrieval systems in returning relevant design patents to support FTO review, with metrics such as Hit Rate@K and PRES@N used for scoring.
