This article discloses and describes a new research dataset representing the Canadian Intellectual Property Office's historical archive of trademark applications. This individual-application-level dataset includes all applications since approximately 1980, and many preserved applications and registrations dating back to the beginning of Canada's trademark registry in 1865, totaling over 1.6 million application records. It includes comprehensive bibliographic and lifecycle data; trademark characteristics; goods and services claims; identification of applicants, attorneys, and other interested parties (including address data); detailed prosecution history event data; and data on application, registration, and use claims in countries other than Canada. Both the dataset and the code used to build and analyze it are presented for public use on open-access terms at https://doi.org/10.5281/zenodo.4999655. This article uses the dataset to generate novel descriptive analyses of the performance of Canada's trademark registration system and the behavior of applicants for registration, both independently and in comparison to the United States and Australia. These analyses suggest that Canada's trademark registration system is substantially underperforming other nations with respect to efficiency of examination, and that recent statutory and regulatory changes in Canadian trademark law may have the effect of masking or even exacerbating this underperformance while decreasing the reliability of the Canadian trademark registry as an authoritative guide to trademarks used in Canadian commerce.

加拿大商标数据集

本文公开并描述了一个新的研究数据集，该数据集代表了加拿大知识产权局的商标申请历史档案。这个个人申请级别的数据集包括大约自 1980 年以来的所有申请，以及许多可追溯到 1865 年加拿大商标注册开始时的保存申请和注册，总计超过 160 万条申请记录。它包括全面的书目和生命周期数据；商标特征；商品和服务索赔；申请人、律师和其他相关方的身份（包括地址数据）；详细的起诉历史事件数据；以及在加拿大以外的国家/地区的申请、注册和使用声明的数据。数据集和用于构建和分析它的代码都在 https://doi.org/10.5281/zenodo.4999655 上以开放访问条款提供给公众使用。本文使用该数据集对加拿大商标注册系统的表现和注册申请人的行为进行了新颖的描述性分析，无论是独立的还是与美国和澳大利亚的比较。这些分析表明，加拿大的商标注册系统在审查效率方面的表现远逊于其他国家，而加拿大商标法最近的法律法规变化可能会掩盖甚至加剧这种低劣表现，同时降低加拿大商标的可靠性注册作为加拿大商业中使用商标的权威指南。
