Abstract: Recently, research for network has been actively progressing. 
Internet, bio-metabolic, and coauthor networks of scientific thesis has a 
decreasing distribution to power law. However, researches on network 
utilizing patent information have not been very active. It suggests the 
method calculating large sparse matrix by supercomputer, examining patent 
network distribution by bibliographic coupling and co-citation, and 
identifying influential patents. The majority of studies, which are 
targeted to find Hub patents, are using the number of forward citation of 
patents. Yet the most recent technological convergences among different 
fields have been enforced, and the development of this fusion technology 
has been rapidly progressing. Therefore the forward citation of patent 
occurs in the applicable field of technologies as well as in other fields 
of technology; the method to find influential patents within the 
applicable field of technology is using only the number of forward 
citation of patents that may cause severe distortions. This study will 
explore three types of influential patents by minimizing the distortion 
phenomenon accompanied by the number of patent forward citation. To serve 
this purpose, the patent classification method is using bibliographic 
coupling and co-citation analysis used in knowledge search.
