Design Patent Map as a Basis for Product Design Development in Creative Design Industry

Because a design patent is considered less definite than other patent categories such as an invention patent, it is difficult to create a design patent map for design strategy planning in the creative design industry. To solve this problem, this research uses two classification methodologies to provide an example of an innovative design patent map using multivariate analysis: multidimensional scaling (MDS) and cluster analysis. Thirty-eight chair design patents in Taiwan from 2010 to 2012 are selected as the sample cases for patent mapping. The findings reveal that the two design patent maps based on the MDS method and cluster analysis fall into similar design categories. The comparison study shows that the MDS-based design patent map is better at external environmental monitoring, including design trend analysis, selection of design hot zones, design forecasting, and evaluation of major competitors. Meanwhile, the cluster-based design patent map is useful in understanding the design patterns of all existing patents using the given clustering variables. Further design pattern analysis such as patent valuation, current design categorization, and self-positioning can also be easily performed using this approach.
