In order to produce a good, it is necessary to take several manufacturing processes sequentially applied. Each process includes a number of technologies such as material technology, process technology and equipment technology. Enterprises that produce identical components generally operate similar processes, but there are unique characterises of each enterprise when we look inside their processes closely. In this context, this paper tires to compare and explain technological differences of two enterprises - M, the leading enterprise, and S, the competing enterprise in the field of producing MLCC in recent years. For this analysis, this paper collects all patents data of two companies during 10 years (2004~2013), and examines the patent information(forward citation, family, apply) that is related to their main products. This paper looks closely into the contents that each patent contains. According to this method, patents, an enterprise holds are classified by series of manufacturing processes. In addition, this paper also tries to examine the relationship between patents and technologies of the enterprise. As a result, this paper finds the main processes and technologies that the enterprise focuses its capacity and the unique characteristics of the enterprise. With this method, this paper finds core processes of the leading enterprise. It would be possible for following or competing enterprises to decide the field that they should focus their capacity prior to other fields in order to occupy dominant position in the market.
