Patent Bibliometrics Analysis on Biofuel Cell

Based on biofuel cell patents downloaded from Derwent Innovation Index database,the paper conducts a patent bibliometrics analysis on biofuel cell technologies from the perspective of parents date,technology fields,country and patent assignees,and draws collaboration networks by using Ucinet software to analyze cooperative RD on biofuel cell patents,thus providing support for government,research institutes and enterprises in making the science and technology development plans and RD projects,searching cooperative partners,as wellunderstanding the competition pattern and industrial development trend.
