A Study on Technology Competition of Graphene Biomedical Technology Based on Patent Analysis

Abstract

Graphene, with high biocompatibility, physiological solubility and stability, has been reported as an emerging material for biomedical applications such as biosensors, drug delivery, and tissue engineering. Recently, identifying the technological competition (TC) of graphene biomedical technology has received worldwide attention from stakeholders. However, few studies have attached great importance to review the TC of this field by the analysis of patents. The main objective of this study is to develop a new and comprehensive method to investigate TC in a given technology field by conducting a patent review and then employing a patent roadmap to dig out the technology opportunity. The effectiveness of the approach is verified with the case study on graphene biomedical technology. Compared to previous research, this study makes the following important contributions. First, this study provides a new and systematic framework for the dynamic analysis of TC in a given technology field. It also extends the research perspectives of TC for industry, assignees, and technology, employs a patent roadmap to dig out technology opportunities, and enables stakeholders to understand TC from a dynamic perspective. Second, this study integrates patent analysis with a patent roadmap that has not appeared in existing methodologies of patent review. Third, it first introduces indicators (e.g., high value patent and competition position of top assignees) to the previous patent roadmap and provides a new methodology for patent roadmaps from a country level and assignee level. Finally, this study provides useful information for stakeholders interested in graphene biomedical technology, helps them to find new technology opportunities in this field, encourages them to determine the direction of future research, and has important significance for its application to diverse other emerging technologies.

Technology Development Roadmaps: A Bibliometric Analysis of Scientific Literature

“…The names of clusters were proposed, which made it possible to identify research sub-areas and main research issues, in which the authors of the publications used technology development roadmaps (Table 1). Analysis of patent development patterns (Jeong and Yoon, 2015;Yu and Zhang, 2019;Trappey et al, 2019;Zhou et al, 2019;Yang et al, 2019);…”

Effective Identification of Technological Opportunities for Radical Inventions Using International Patent Classification: Application of Patent Data Mining

“…Patents are considered one of the most reliable data resources for technological opportunity identification [9][10][11], due to their integrity of technical information, standardization of document management, and availability of data. Studies have suggested methods of identifying technological opportunities through drawing patent citation networks, to identify core patents as technological opportunities [12][13][14], establishing a morphological matrix to identify prioritized combinations of patents as technological opportunities [15], and constructing semantic patent maps, to identify patents hotspots and outlier patents as technological opportunities [16][17][18].…”
