Abstract: Corporate scientists that are involved in scientific activities, often leading to research paper publications, are important for corporate innovation, since science-based innovation tends to be transformative, spanning the boundaries of existing R&D pipelines. Such scientists can also play a role as a bridge between academic researchers, injecting scientific knowledge from outside the firm. However, the publication of internal corporate scientific activities could benefit competitor firms, providing them with input towards their own transformative innovation. In this study, we analyze this trade-off using a linked dataset of research papers and patents (disambiguated by paper author and patent inventor information and patent citation in research papers) of Japanese firms. Specifically, we analyzed two aspects, (1) contribution of corporate scientist research papers to in-house innovation (patent) and (2) capacity of corporate scientists to absorb scientific findings from outside their firms to obtain high quality patents. Our findings indicate that corporate scientists contribute to both aspects of innovation in their firms.
