Innovation development trends of ceramic technology based on patent analysis

This study investigates the innovation development trends in ceramic technology through an extensive patent analysis. In response to the growing need for reliable data on technological activities across sectors, patent analysis has emergedas a powerful tool to track and measure innovation. The ceramic industry, known for its applications in manufacturing,electronics, and biomedicine, serves as the focal point of this research. Utilizing data from key patent databases, includingthe European Patent Office (EPO), the United States Patent and Trademark Office (USPTO), and the World IntellectualProperty Organization (WIPO), the study examines patent filings over the last two decades. Metrics such as patent filingtrends, technology clustering, geographical distribution, and top innovators are employed to reveal the dynamics of ceramictechnology advancements. In addition to patent data, the Literature-Based Innovation Output (LBIO) method is incorporated,which identifies innovations from technical and trade journals. This method captures innovations, particularly those nottypically patented, providing a broader perspective on the industry’s innovation output. Findings suggest a significantincrease in innovations, especially in structural ceramics, electronic ceramics, and bioceramics, with contributions fromleading firms and academic institutions worldwide. However, limitations in patent data, such as the focus on product overprocess innovations, are addressed. The research offers valuable insights into the evolving landscape of ceramic technology,highlighting key innovators, global trends, and the impact of emerging technologies such as nanotechnology. The study’sfindings contribute to a deeper understanding of ceramic innovation trends and inform strategic decision-making for industrystakeholders.
