This paper analyses the impacts of the recent discussion to extend patentability to computer-implemented inventions, i.e. to allow software patents, in Europe. Based on two surveys among the German software sector referring to the use and importance of IPR in the year 2000 and 2004, the analysis finds that the share of companies using patents in the software sector remains constant, but the relevance of this instrument increased significantly for the active users of patents. Based on a set of hypotheses on the determinants for the use of patents, we also find changes. The size bias of patent use increased, whereas there is a dichotomy between using patents and following the open source model in the software sector and not a convergence, as has been suggested by the anecdotal evidence of some large multinationals. These changes in the software sector generate several new challenges for policy makers responsible for the IPR regime relevant for software in addition to the still unsolved question of extending patentability to software in Europe.
