Patents have long been regarded as the 'gold standard' of intellectual property protection. In 'Little patents and big secrets: managing intellectual property', Anton and Yao (2004) call this traditional view into question by finding that firms keep their most important innovations secret. This...

Traditionally patents are seen as the gold standard for intellectual property protection. But, in line with empirical findings that secrecy is considered more important for appropriating returns, recent theories predict that firms keep their most important inventions secret. This article...

Technological change is often hypothesized as one of the main drivers of merger activities. This paper analyzes the role of technology in mergers and acquisitions (M&As) at the firm level. Based on a newly created data set that combines financial information and patent data for public limited...

This paper presents an empirical analysis of the determinants of patent litigation in Germany, based on information from suits filed during the period from 1993 to 1995 at two of the three most important district courts. A control group was formed by selecting a random sample from the population...

In the 1990s, patenting schemes changed in many respects: upcoming new technologies accelerated the shift from price competition towards competition based on technical inventions, a worldwide surge in patenting took place, and the ?patent thicket? arose as a consequence of strategic patenting....

Through a survey, economic value estimates were obtained on 962 inventions made in the United States and Germany and on which German patent renewal fees were paid to full-term expiration in 1995. A search of subsequent U.S. and German patents yielded a count of citations to those patents....

We explore the tail of patented invention value distributions by using value estimates obtained directly from patent holders. The paper focuses on those full-term German patents of the application year 1977 which were held by West German and U.S. residents. The most valuable patents in our data...

Over the last few years, worldwide mergers and acquisitions (M&A) have increased sharply both in terms of value and volume. This development has not only been driven by corporate acquirers but also to an increasing extent by private equity investors. In this paper, we analyze differences in...

Gaining access to technological assets and patents, in particular, has long been a major motive and objective for firm acquisitions. On the one hand, patents are used as a building instrument for the acquirer's technology portfolio. On the other hand, patents can be attractive because of their...

The knowledge produced by academic scientists has been identified as a potential key driver of technological progress. Recent policies in Europe aim at increasing commercially orientated activities in academe. Based on a sample of German scientists across all fields of science we investigate the...
