Generally patent strategies are derived through quantitative and qualitative analysis of data collected from
patent databases in related fields. In areas where customer needs are important, changes in technology are
sensitive to user needs and strategies for securing customer-centric technologies are established. In this
paper, we study how a user survey result, which is mainly used as a method to grasp the customer 's
demand can be combined with quantitative patent data analysis, which is a traditional approach, in order to develop patent strategy. Establish various patent strategies based on the similarities or differences between
the survey results and the patent quantitative analysis results. In a case study of smartphone camera, we
show that our patent strategies proposed in 2013 are alined with the trends of actual products developed
later. Also, we propose guidelines how to design survey questionaries and how to analyze the survey result
for developing patent strategy.
