China recently surpassed the USA as the greatest global source of patent applications. However, without internationally comparable measures of patent quality it remains questionable whether China's patent expansion constitutes the rise of a new technological superpower. Our novel quality index...

Although merger and acquisitions (M&As) are acknowledged as an important means to access innovative assets and know-how, firms' inventive output often declines in the post-M&A period. Financial, managerial and organizational constraints related to the M&A event contribute to inventive output...

We investigate the causal effect of patent rights on cumulative innovation, using large-scale data that approximate the patent universe in its technological and economic variety. We introduce a novel instrumental variable for patent invalidation that exploits personnel scarcity in post-grant...

This paper analyzes the use and effectiveness of patents and trade secrets designed to protect innovation. While previous studies have usually considered patents and trade secrets as substitutes for one another, we investigate to what extent and in what situations the two protection methods are...

Patents are widely used in the literature as a measure of firm-level innovation. It is regarded that patents improve a firm’s operational environment and ultimately increase the value of the firm. However, the relationship between patents and firm value in Korea is under-explored in the...

The positive effect of public research on industrial innovations is beyond controversy: public research institutions produce knowledge that is subsequently transferred into product and process innovations by private businesses. Besides this rather passive role in commercializing inventions,...

Previous research has expressed concerns about firms engaging less in basic research. We contribute to this debate by studying trends in the scientific publishing activities of firms located in Germany. Our results do not confirm a declining trend in raw numbers with numbers indicating that...

Herbert Zech, Humboldt-Universität zu Berlin, fällt insgesamt ein positives Urteil zum Patentschutz: Er ermögliche technische Innovation in Bereichen, in denen sich Entwicklungsaktivitäten wegen leichter Nachahmbarkeit und hohen Investitionsbedarfs ansonsten nicht lohnen würden....

Firms use a variety of practices to disclose the knowledge generated by their R&D activities, including, but not limited to, publishing findings in scientific journals, patenting new technologies, and contributing to developing standards. While the individual effects of engaging in the listed...

In this article, we explore the Covid-19 crisis through the lens of innovation. We focus on the threat and opportunity drivers of innovation, and some of their product/service and process outcomes. We contribute to crisis innovation theory and practice by suggesting that there are two categories...
