Markush structures are molecular skeletons containing not only specific atoms but also placeholders to represent broad sets of chemical (sub)structures. As genus claims, they allow a vast number of compounds to be claimed in a patent application without having to specify every single chemical...

Firms pursue a number of strategies to appropriate value, including patenting. In this paper I study patent fencing, a specific filing strategy to use multiple related patents to further enhance value appropriation. The paper addresses the pharmaceutical industry, which shows a high patenting...

Achieving patent protection for an invention is a costly procedure. The patenting process in front of the patent office itself is frequently associated with substantial uncertainty about the outcome. This paper aims to identify measures to reduce this uncertainty and increase efficiency in...

The present paper reviews the literature on social network analysis with applications to bibliometric data, and in particular, patent information. Several approaches of network analysis are conducted in the field of optoelectronics to exemplify the power of network analysis tools. Cooperation...

The aim of this paper is to provide an overview of different statistical analyses from patent and literature databases that in combination are helpful for a variety of mostly strategic decision settings in firms. For the case of optoelectronics we assess the patenting and publishing activity of...

Exemplifying the case of PATON, a large patent information centre in Germany, this paper describes a wide range of services PATLIB centres can offer today. The expansion of its scope of products and services beyond classical patent information in order to become a regional patent centre is also...

This paper investigates different types of innovations (from radical to incremental) in the pharmaceutical industry by studying bibliometric data of drugs approved by the United States Food and Drug Administration (FDA), looking at time-to-market aspects, knowledge sources of these innovations,...
