Abstract
Purpose –This study aims to propose a visualized model of hot technology evolution to describe its
development.
Design/methodology/approach –The basic concept is to divide a technological field into a timeline
consisting of several patent clusters.Hot technology trajectories are then explored using their continuity,as
well as the point in time at which they occur.
Findings –Patents in orthopaedics between1999 and 2014 have been chosen as the research subjects and
the field is divided into several hot technology trajectories. A further step is taken by interpreting high-
frequency key terms. Three categories –spine-related materials, bone repairingmaterials and bone plates –
have been identified.
Practical implications –The trajectories presented by evolvingdiagrams allow readers to understand
the evolutionof hot technology and help analysts to planlayout and strategies to remain competitive.
Originality/value –Patent clusters reflect the knowledge context of technology development. Previous
studies havefocused on only new technology evolution andhave rarely explored the knowledge contextof hot
patents that have been frequently cited in recent years. Such patents often guide the development of
technology.

Introduction
During the development of new technology, government agencies, business organizations
and research institutes often invest large amounts of resources, hoping to make a
breakthrough in the field. However,without big data analytics of patent documents ahead of
time, the decision toinvest often relies on only expert opinion (Landeta,2006). It is becoming
increasingly difficult to provide technological insights using only expert opinion because
technological knowledge is growing so fast that there is no expert who can fully
comprehend the entire knowledge picture for a specific technological domain. The
development of policy without evidence is subjective and can result in misallocation of
resources and missed opportunities. A map is needed for guidance when engaging in a
