  • Patentometric analysis of the process technologies of Companhia Siderúrgica Nacional (CSN)

    This article aims at profiling the technological development of production processes of Companhia Siderúrgica Nacional (CSN). It analyzes the deposits of patent of CSN between the years of 1971 and 2009, classifying them in product technologies and process technologies. It was concluded that the CSN has made more deposit of patent for process technology than…

  • 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…

  • Text mining to gain technical intelligence for acquired target selection: A case study for China’s computer numerical control machine tools industry

    Technology strategy plays an increasingly important role in today’s Mergers and Acquisitions (M&A) activities. Informing that strategy with empirical intelligence offers great potential value to R&D managers and technology policy makers. This paper proposes a methodology, based on patent analysis, to extract technical intelligence to identify M&A target technologies and evaluate relevant target companies to…

  • Building a View of the Future of Antibiotics Through the Analysis of Primary Patents

    The primary patent application of a new drug is the application that claims the chemical structure of that new compound and is usually the first patent filled regarding that new drug. Therefore, the analysis of the recent primary patents in a therapeutic group reflects the results of the research toward finding new compounds and allows…

  • Technological forecasting of hydrogen storage materials using patent indicators

    Hydrogen is a promising future energy carrier due to its high energetic content and sustainable appeal when produced via clean manufacturing processes. One of the technological challenges concerns its storage in a safe, compact, low mass and high gravimetric capacity manner. In this sense, many Hydrogen Storage Materials (HSM) have been investigated to house this…

  • Monitoring emerging technologies for technology planning using technical keyword based analysis from patent data

    This paper proposes technical keyword-based analysis of patents to monitor emerging technologies, and uses a keyword-based model in contents-based patent analysis. This study also presents methods to automatically select keywords and to identify the relatedness among them. After using text-mining tools and techniques to identify technical keywords, a technical keyword-context matrix is constructed. The relatedness…

  • Case study of patents related to captopril, Squibb’s first blockbuster

    Arterial hypertension affects over one billion people around the world, making the prevention and treatment of this disease vital. Despite the efforts made to develop new antihypertensive drugs, few new therapies have become available. Angiotensin-converting enzyme (ACE) inhibitors have heralded major steps forward in the treatment of arterial hypertension and cardiovascular diseases since the first…
