Development of a patent roadmap through the Generative Topographic Mapping and Bass diffusion model

This paper aims to present a novel concept roadmap the patent roadmap and suggest an advanced patent roadmapping process, based on the Generative Topographic Mapping (GTM) and Bass diffusion model. The process for patent roadmapping is composed of two modules: Developing the GTM-based patent map and determining the appearance time of the emerging patent through Bass model. The result of this research is meaningful knowledge from analyzing a vast store of patent data with quantitative methods and automated tools. It can serve as an effective patent planning tool, and proposes a strategic Research and Business Development (R&BD) for both firms and governments. (c) 2015 Elsevier B.V. All rights reserved.
