  • Assessing technological developments in amorphous/glassy metallic alloys using patent indicators

    Alloys with an amorphous structure represent a class of advanced metallic materials which have great potential for industrial applications and technological innovations as a consequence of their interesting chemical, mechanical and magnetic properties. Considerable effort has been devoted to investigating scientific issues concerning these alloys, but less attention has been paid to assessing the impact…

  • A hybrid similarity measure method for patent portfolio analysis

    Similarity measures are fundamental tools for identifying relationships within or across patent portfolios. Many bibliometric indicators are used to determine similarity measures; for example, bibliographic coupling, citation and co-citation, and co-word distribution. This paper aims to construct a hybrid similarity measure method based on multiple indicators to analyze patent portfolios. Two models are proposed: categorical…

  • Patent information retrieval: approaching a method and analysing nanotechnology patent collaborations

    Many challenges still remain in the processing of explicit technological knowledge documents such as patents. Given the limitations and drawbacks of the existing approaches, this research sets out to develop an improved method for searching patent databases and extracting patent information to increase the efficiency and reliability of nanotechnology patent information retrieval process and to…

  • International Collaboration Patterns and Effecting Factors of Emerging Technologies

    With the globalization of the world economy, international innovation collaboration has taken place all over the world. This study selects three emerging technologies (3D printing, big data and carbon nanotubes and graphene technology) among 20 countries as the research objects, using three patent-based indicators and network relationship analysis to reflect international collaboration patterns. Then we…
