Patent analysis for guiding technology transfer from EU/EEA to China: The case of CO2 compressor in CCUS cooperation

Carbon Capture, Utilization and Storage (CCUS) technology is believed as an effective approach to control and reduce CO₂ emission in China. We take CO₂ compressor in CCUS as object of research and technological backgrounds to build up a patent analysis model in both statistics and bibliometrics approaches for guiding patent technology transfer. Patent bibliometrics analysis is more progressive compared with statistics analysis and goes further from the shallower to the deeper depth in technology analysis. We find patent analysis and technology transfer have internal theoretical relations and realistic relevance since patent analysis can play an unsubstitutable role in the preliminary stage of technology transfer in identifying IP ownership, technology gap, sources, distributions, characteristics and application domains. We compare these aspects on CO₂ compressor in CCUS between EU/EEA and China from patent analysis view and define the necessities for technology transfer in clean energy context. Finally, we summarize IP policy implications and suggest patent technology transfer mechanisms based on the patent analysis model so as to ensure substantial achievements in future mutually beneficial cross-border clean energy technology transfer.
