The EPO traditionally grants at least 60% of all patent applications, the rest being either withdrawn (30-35 %) or refused (5%). This paper provides quantitative evidence suggesting that up to 54% of all patent withdrawals could be considered as induced by the work of EPO examiners, and hence...

The decision of firms to renew their patents is largely assumed to be the result of a careful valuation exercise to balance their expected revenues with renewal fees. This article extends this line of reasoning to all patent applications filed to the EPO over a 20 years period and analyzes with...

The renewal of patents and their geographical scope for protection constitute two essential dimensions in a patent’s life, and probably the most frequently used patent value indicators. The intertwining of these dimensions (the geographical scope of protection may vary over time) makes their...

This paper aims at contributing to the literature on the determinants of patent value. First, it puts forward a new potential class of value determinants in the form of filing strategies (encompassing filing routes and drafting styles). Second, it provides empirical evidence suggesting that...

This paper analyses the industrial and entrepreneurial value of 334 patent families applied for by six major Belgian universities. It identifies the value determinants underlying the patent documents and highlights the positive and significant impact of collaboration and tacit scientific...

Cet article propose une analyse de l’évolution et des déterminants des stratégies de dépôt de brevets et leur impact sur les systèmes de brevets. La motivation de cette recherche réside dans l’évolution des pratiques (rédaction et dépôt des demandes) au cours des 20 dernières...

The aim of this paper is to describe the patent systems of fast developing Asian countries (China, Indonesia, Philippines, Thailand and Vietnam) and understand the factors that drive the demand for patent in these countries. Patent systems in these countries have strengthened to a large extent,...

Given the growing size of patent databases and portfolios, scholars and practitioners alike need metrics to help them in weighting patent counts or in ranking patents to focus on the most important ones. The main objective of this paper is to help them in this task with a practical and...

This article reviews the literature on knowledge transfer mechanisms (KTMs) used in university-industry interactions. The literature may be articulated around four dimensions: (i) the relative importance of KTM as perceived by the involved stakeholders, (ii) the factors affecting the...
