令人惊讶的是，很少有实证研究集中在从美国专利商标局（PTO）获得专利授权的过程中。本文档的目的是描述专利审查数据集（PatEX），使来自公共专利申请信息检索系统（Public PAIR）的大量信息更容易为研究人员所用。PatEX包括超过900万件美国专利申请的记录，截至2015年1月24日，所有申请日期在2015年1月1日之前的申请都在Public PAIR中完成。PatEX中的变量涵盖了与美国专利审查相关的大部分信息，包括发明、申请、申请人、律师和审查员的特征，以及申请人和审查员在整个审查过程中采取的所有行动的状态代码。本文档的重要部分描述了由于忽略“非公开”应用程序而产生的选择性问题。我们发现，选择的问题是更明显的申请之前收到的美国发明人保护法（AIPA）在2000年底实施。我们还发现，在任何特定的研究项目中，任何选择偏差的程度至少部分取决于感兴趣的亚群。
A surprisingly small amount of empirical research has been focused on the process of obtaining a patent grant from the United States Patent and Trademark Office (PTO). The purpose of this document is to describe the Patent Examination Dataset (PatEX), make a large amount of information from the Public Patent Application Information Retrieval system (Public PAIR) more readily available to researchers. PatEX includes records on over 9 million US patent applications, with information complete as of January 24, 2015 for all applications included in Public PAIR with filing dates prior to January 1, 2015. Variables in PatEX cover most of the relevant information related to US patent examination, including characteristics of inventions, applications, applicants, attorneys, and examiners, and status codes for all actions taken, by both the applicant and examiner, throughout the examination process. A significant section of this documentation describes the selectivity issues that arise from the omission of “nonpublic” applications. We find that the selection issues were much more pronounced for applications received prior to the implementation of the American Inventors Protection Act (AIPA) in late 2000. We also find that the extent of any selection bias will be at least partially determined by the sub-population of interest in any given research project.
