Abstract: The goal of this report is to characterize the small world 
phenomenon in the patent citations network by analyzing the data of TFT-
LCDs patents. The empirical results suggest that the patent citation 
network can indeed be characterized as "small world". Additionally, the 
patent citation network resembles the power-law connectivity distribution 
and exhibits preferential connectivity behavior. Furthermore, as a patent 
with high betweenness centrality is removed from the citation network, 
50.6% of the patent knowledge communication will be limited. The result of 
this analysis will provide a specific way for managers to map their own 
patent networks and derive insight into the best ways to navigate within 
such networks.
