Abstract The importance of the patent market has increased in the high technology market due to open innovation and social efficiency. As most high-tech firms cannot rely on their own repository of technologies, they need to employ external technologies. These can be acquired through mergers and acquisitions (M&A) or from the patent markets, which is often referred to as open innovation. Because of insufficient comprehensive data and the complexity and contingency provision of the contract, there have been only a few empirical studies on patent transactions. This study seeks to understand the patenting activities of patent buyers after acquisition. By merging patent bibliographies and patent assignment information, the original dataset was prepared to investigate the patent acquisition activities of the patentees who were granted patents from 2007 to 2011 and their patent application activities from 2012 to 2016. The factors affecting patent production and acquisition and the relationship between patent acquisition and subsequent production were examined. The results show that the patent acquisition activity depends on the applicant type and technology field, and affects the future patent production of the applicant. Thus, observing a competitor's patent acquisition activities gives insights into the future direction of its technology development.

专利获取对后续专利申请活动的影响

摘要 由于开放式创新和社会效率，专利市场在高科技市场中的重要性日益增加。由于大多数高科技公司不能依赖自己的技术库，他们需要使用外部技术。这些可以通过并购 (M&A) 或从专利市场获得，这通常被称为开放式创新。由于综合数据不足以及合同的复杂性和意外性规定，对专利交易的实证研究较少。本研究旨在了解专利购买者在获得专利后的专利活动。通过合并专利书目和专利转让信息，原始数据集用于调查2007-2011年被授予专利的专利权人的专利获取活动及其2012-2016年的专利申请活动。考察影响专利生产和获取的因素以及专利获取与后续生产的关系. 结果表明，专利获取活动取决于申请人类型和技术领域，并影响申请人未来的专利生产。因此，观察竞争对手的专利收购活动可以洞察其技术发展的未来方向。考察了影响专利生产和获得的因素以及专利获得与后续生产的关系。结果表明，专利获取活动取决于申请人类型和技术领域，并影响申请人未来的专利生产。因此，观察竞争对手的专利收购活动可以洞察其技术发展的未来方向。考察了影响专利生产和获得的因素以及专利获得与后续生产的关系。结果表明，专利获取活动取决于申请人类型和技术领域，并影响申请人未来的专利生产。因此，观察竞争对手的专利收购活动可以洞察其技术发展的未来方向。
