The innovative activities by firms are considered to be the main driving force of the economic growth. The patent data has been widely used to investigate the relationship between R&D and patents which are taken as an output indicator of the new invention or innovation. On the other hand, empirical evidence supports that teamwork of inventors fosters innovation and technological progress. Motivated by the importance of understanding the patenting behavior of firms and collaboration of inventors, we exploit the continuing applications of patents, examine the R&D and patents relationship, and investigate the effects of teamwork on innovation output.

520 $a The innovative activities by firms are considered to be the main driving force of the economic growth. The patent data has been widely used to investigate the relationship between R&D and patents which are taken as an output indicator of the new invention or innovation. On the other hand, empirical evidence supports that teamwork of inventors fosters innovation and technological progress. Motivated by the importance of understanding the patenting behavior of firms and collaboration of inventors, we exploit the continuing applications of patents, examine the R&D and patents relationship, and investigate the effects of teamwork on innovation output.
520 $a Chapter 1 studies the role of continuing patent applications across six main technological fields in the United States during 1976-2012. The research represents the first effort of which we are aware to analyze patent application data on continuing histories, providing information on the effects of 1995 GATT legislation changes in the US patent law intended to curb "submarine patenting". We employ novel data on filings of three types of continuing applications - the continuations, the continuation in part, and divisions to distinguish among the motives for continuing patents. We find that the GATT legislation reduced continuing applications overall and mitigated submarine patenting. The disparate impact of the GATT change will be most acute on pharmaceutical and chemical industries.
520 $a Chapter 2 studies the relationship between R&D expenditures and patenting in the context of the U.S. chemical and pharmaceutical industries during the 1981-2003 period. Our empirical analysis differs from previous work that investigates the patents- R&D relationship in two main aspects. First, we substitute priority date of a patent for application date as a proxy for the invention date which ties the timing of innovation to patenting. Our estimation results exhibit the change of marginal effect on R&D by using priority date compared to application date. Second, we develop a new transformation of the quasi-differenced GMM estimator that allows for endogenous regressors with the dynamic linear feedback model. Our empirical results from various count panel data models show that the correlation between R&D and patents is higher by using priority date than application date for the pre-GATT period and lower for the post-GATT period. This implies that the 1995 legislation change in patent term has reduced continuing patent applications and effectively alleviated the submarine patent problems particularly in the chemical and pharmaceutical industries.
520 $a Chapter 3 studies the impact of inventor team characteristics on the quality of innovation outputs. We investigate the impact of two attributes of teamwork - team composition and persistence on the quality of patentable inventions, using the number of claims and forward citations as proxy for patent quality. The analysis on team composition is conducted at inventor-team level and we show that both the skillset diversity of team members and the presence of generalist inventors have positive impacts on the quality of patents. We also conduct a firm level analysis on team persistence and use firm dissolution as an instrumental variable to control for endogeneity in our estimation. We show that the team persistence has a positive impact on patent quality.
