| Summary/Abstract |
Improved understanding of the innovative pathways of renewable energy technologies is vital if we are to make the transition to a low carbon economy. This study presents new evidence on innovation and industry dynamics in concentrating solar power (CSP) technologies. Though CSP is undergoing a renaissance, existing innovation studies have explored innovative activity in solar technologies in general, ignoring the major differences between solar photovoltaic and CSP technologies. This study, based on patent data, examines the level and dynamics of innovative activity in CSP between 1978 and 2004.
Our unique contribution, based on engineering expertise and detailed datawork, is a classification system mapping CSP technologies to the International Patent Classification (IPC) system. The innovation performance of CSP is found to be surprisingly weak compared to the patent boom in other green technologies. Performance was strong around 1980 before falling dramatically, and has only recently begun to show signs of recovery. Innovation and R&D are concentrated in high-tech countries; the US, Germany and Japan, which do not necessarily have high domestic CSP potential. Large CSP potential is, therefore, not a sufficient condition for innovation. Innovators must possess economic and scientific capabilities.

| Summary/Abstract |
This study compares the innovation process of Huawei and ZTE in China using their patent data. By using patent statistics and raw data, this study provides more detailed findings than what statistics alone can provide. Huawei and ZTE were selected for this study mainly because they were the only Chinese firms that ranked among the top 100 PCT applicants in 2011. This study investigates the difference in the innovation process in R&D between Huawei and ZTE by analyzing (1) domestic and international patent application patterns, (2) granted patents, (3) co-applicants and inventors, (4) knowledge accumulation inside Huawei and ZTE, and (5) knowledge spillover to domestic and foreign firms.

| Summary/Abstract |
Biofuel policies are motivated by a plethora of political concerns related to energy security, environmental damages, and support of the agricultural sector. In response to this, much scientific work has chiefly focussed on analysing the biofuel domain and on giving policy advice and recommendations. Although innovation has been acknowledged as one of the key factors in sustainable and cost-effective biofuel development, there is an urgent need to investigate technological trajectories in the biofuel sector by starting from consistent data and appropriate methodological tools. To do so, this work proposes a procedure to select patent data unequivocally related to the investigated sector, it uses co-occurrence of technological terms to compute patent similarity and highlights content and interdependencies of biofuels technological trajectories by revealing hidden topics from unstructured patent text fields. The analysis suggests that there is a breaking trend towards modern generation biofuels and that innovators seem to focus increasingly on the ability of alternative energy sources to adapt to the transport/industrial sector.
