  • The Platycodon grandiflorum (balloon flower) has been used as food material and traditional medicine in Asia. The roots have been used in traditional medicine to treat coughs, upper respiratory infections, and sore throats. Using 1,603 valid patents from 6 countries, we analyzed the patent trend based on year, countries, applicants, and technology. The technologies are categorized into 6 groups which include material, additives, manufacture, cultivation, breeding and seed. The technology competitiveness of countries were analyzed with quantitative factors such as cites per patent, patent impact index, patent family size and technology strength. In comparison with other countries in the patent index, South Korea shows an increasing trend in patent numbers and total leverage ability, although the individual technology is lower than Japan and USA. Our study provides information on technical trend to support the performance of new projects on balloon flower.

  • Purpose The purpose of this study is to analyze the trend of patent technology in textile materials using text mining methodology based on Dynamic Embedded Topic Model and Structural Topic Model. It is expected that this study will have positive impact on revitalizing and developing textile materials industry as finding out technology trends. Design/methodology/approach The data used in this study is 866 domestic patent text data in textile material from 1974 to 2020. In order to analyze technology trends from various aspect, Dynamic Embedded Topic Model and Structural Topic Model mechanism were used. The word embedding technique used in DETM is the GloVe technique. For Stable learning of topic modeling, amortized variational inference was performed based on the Recurrent Neural Network. Findings As a result of this analysis, it was found that 'manufacture' topics had the largest share among the six topics. Keyword trend analysis found the fact that natural and nanotechnology have recently been attracting attention. The metadata analysis results showed that manufacture technologies could have a high probability of patent registration in entire time series, but the analysis results in recent years showed that the trend of elasticity and safety technology is increasing.

  • The purpose of this study was to analyze the patent application trend in the processing technology for medicinal herbs. Recently, in processing technology for medicinal herbs, experimental researches have frequently been published through papers in journals. However, the research results about the patent area were fewer than the others. We tried to analyze the patent application trend in nonthermal processing technologies for medicinal herbs by country as Korea, Japan, U.S.A. and Europe. The detailed technologies consisted of pulsed electric field, oscillatory magnetic field, intense pulsed light, ultrasonification, high hydrostatic pressure, microwave, radiation, Ohmic heating, and supercritical extraction. As a result we found that patents of nonthermal processing technologies has been growing steadily in quantity from 1980s and growing quickly since 2000s. The number of patent in Korea is larger than others as making up 70% in that whole. The number of patent in ultrasonification field was larger than others in portfolio analysis. Patent application trend in nonthermal processing technologies for ingestion occupies high share compared to other usage applications. In conclusion, patent trends of nonthermal processing technologies for medicinal herbs belong to the period in the development.
