ABSTRACT This work investigates the relationship between proxies of innovation activities, such as patents and trademarks, and firm performance in terms of revenues, growth, and profitability. By resorting to the virtual universe of Italian manufacturing and service firms, this work provides a rather complete picture of the Intellectual Property (IP) strategies pursued by Italian firms, in terms of patents and trademarks, and studies whether the two instruments for protecting IP exhibit complementarity or substitutability. In addition, and to our knowledge novel, we propose a measure of concordance (or proximity) between the patents and trademarks owned by the same firm and we then investigate whether such concordance exerts any effect on performance. The results suggest that while patents and trademarks independently exert a relevant impact on firm performance, there is no convincing evidence in favour of a complementary role of IP.

知识产权文书的一致性和互补性

摘要 这项工作调查了创新活动的代理（例如专利和商标）与公司在收入、增长和盈利能力方面的绩效之间的关系。通过诉诸意大利制造和服务公司的虚拟世界，这项工作提供了意大利公司在专利和商标方面所追求的知识产权 (IP) 战略的相当完整的图景，并研究了保护知识产权的两种工具是否展示互补性或替代性。此外，据我们所知，我们提出了一种衡量同一公司拥有的专利和商标之间的一致性（或接近性）的方法，然后我们调查这种一致性是否对绩效产生任何影响。
