      abstract     = {Patent documents provide knowledge about which countries
                      are investing in certain technologies and make it possible
                      to identify potential innovation trends. The aim of this
                      article is to analyze trends in patenting that might result
                      in innovations for three energy technologies: thermochemical
                      conversion of biomass (Bioenergy), lithium-ion battery
                      storage, and hydrogen production by alkaline water
                      electrolysis. Based on different patent indicators, the most
                      active countries are compared to provide insights into the
                      global market position of a country, particularly Germany
                      which is used as a reference here. In line with this, a
                      freely available patent analysis software tool was developed
                      directly using the European Patent Office database through
                      their Open Patent Services. The results for named
                      technologies show that patenting activity of Germany is low
                      in comparison to other countries such as Japan, China, and
                      the US. Whereas the position of Germany for batteries and
                      hydrogen is comparable, bioenergy shows different results
                      regarding the identified countries and the number of patents
                      found. However, a broader context beyond patenting is
                      suggested for consideration to make robust statements about
                      particular technology trends. The presented tool and
                      methodology in this study can serve as a blueprint for
                      explorative assessments in any technological domain.},
