Abstract

Recently, patent forecasting and planning has been emphasized as an essential process in the strategic management of technology because well-planned patents will make larger profits and occupy dominant positions first. Thus, this paper aims to suggest the concept and process of a patent roadmap based on a technology roadmap and patterns of patent development. For this, first, ontology of technology is generated to structure the characteristics of technology based on the existing technology roadmap and then patents are collected from a patent database. Second, collected patents are grouped by similarities based on vectors of extracted keywords and grouping results are classified by TEMPEST. In this step, keywords extracted from the previous phase are matched with TEMPEST individually and patent groups are categorized in accordance with high relevance between representative keywords in patent groups and core keywords in each category of TEMPEST. Third, the patterns of patent development are identified for each patent group and categorized by two types - structural and temporal patterns. Consequently, extracted patterns serve as evidence of patent planning, and the patent roadmap is drawn with the technology layer composed of the technology roadmap and the patent layer that each group is mapped on. The proposed approach is illustrated by the case of the transparent AMOLED display. The patent roadmap will enable managers to establish patenting strategies in order to achieve a valuable core patent that has the potential to become a business model, yielding good returns in the long term.
