Highlights • Technological routes demonstrate that flow of knowledge is concentrated in patents developed in the same country • Strong presence of independent assignees (individuals) instead of firms • Major interest in technology development exclusively on each R&D without any collaborative efforts. • Most promising and emerging technologies for GVP systems are identified • A new taxonomy to technology innovators can be explored based on patent development.
