Abstract: The valuation of intangible assets, such as patents, has 
recently been considered an important technique for RD strategies. This 
paper proposes a citation analysis as a method of valuation on patent 
clusters having patent networks. A citation analysis is a method that 
examines the value of a patent on the basis of the number of citations of 
references. In particular, a co-citation analysis is used for coupling 
patents as the patent cluster and valuating the patent cluster. While the 
co-citation analysis is of great interest as a method of valuation, this 
analysis has not been fully examined and does not define any framework for 
a technology transition and patent strategy. Therefore, in this paper, the 
conventional co-citation analysis for evaluating the patent clusters is 
enhanced and frameworks for the technology transition and patent strategy 
are proposed by analysing citation routes in a co-citation analysis.
