We investigate how a deferred patent examination system promotes ex-ante screening of patent applications, which reduces both the number of granted patents and the use of economic resources for examinations, without reducing the return from R&D. Based on a real option theory, we develop a model...

This paper examines what drives author ordering in scientific research. We first discussa theoretical framework for the choice between alphabetical ordering and relative-contribution-based ordering and develop hypotheses, focusing on the nature of research, in particular, the importance of...

How to design and manage a research team has become an increasingly important issue in knowledge creation in science. This paper aims to understand how young scholars contribute to scientific research in the context of a research team. We have found that the likelihood of the involvement of...

This paper examines the structure and the evolution of the patents declared as essential for three major technical standards in information technology (MPEG2, DVD and W-CDMA). These standards have many essential patents, which are owned by many firms with different interests. Many patents have...
