In this research, we propose a method for searching for new application of invention. The proposed method consists of two steps. The first step is to extract technical features and their effects from patents. The second step is to search for patents with similar technical features and dissimilar effect to a specific query. This method was demonstrated to be useful in searching for new application of invention.
