Background: Medicinal plants are widely used in Asia. They have proven to be an invaluable asset in modern drug discovery and their demand has been steadily increasing across various industries. Methods and Results: Using 4,867 valid patents related to 12 oriental medicinal plants of 10 country groups, the growth and development potential of patents was evaluated. The cites per patent (CPP) and patent family size (PFS) indices were used to evaluate the market capability and technological level of the collected patents. Meanwhile, the patent impact index (PII) and technology strength (TS) were used to compare the technological competitiveness of patents among various technology types and markets. Both CPP and PFS indices showed that magnolia-vine and balloon flower have numerous core or original patents. Furthermore, an increase in both PII and TS indices was observed. A newly designed intellectual property multi-layer (IPM) model predicted that the medicine, genome and cosmetic categories have a high possibility of patent application growth. Conclusions: The IPM model can be used to provide the scope of particular technology fields for patent development. In addition, this study can assist patents to advance in the international market and guide the development of a national industrial strategy.

These days, firms are focusing on the improvement of relationships with business partners. The supply chain integrations are taking critical role in improving the relationships with business partners. In accordance with the development of the IT technology, it became possible for firms not only to integrate inner parts of the organization, but also to integrate the company with other organizations in the supply chain, which is open system. Therefore, in e-Biz environments, it is imperative for firms to strengthen the core capacity through the supply chain integration, and to precisely determine the components of the determinants of e-Business integration which impact the firm performance. This study analyzed determinants that have impacts on business integration in IT capacity perspectives in competetive environments. We analyzed 163 domestic companies to find out many significant suggestive points. First, IT management capacity, process innovation capacity are adopted as determinants of differentiation and competetive edges against competing firms. Second, it is analyzed that the more the companies are in intensified competetive environment, the more likley that the innovation capacity and partner management capacity become the determinants of the business integration of the companies and that they pursue new market development strategy. Third, it is analyzed that the more the companies are in high demand fluctuation, the more likley that the innovation capacity becomes the determinants of the business integration of the companies, and that they pursue new market development strategy and operation efficiency strategy. Last, it is analyzed that the more the companies are Technology dependent, the more likely that IT management capacity and process innovation capacity become the determinants of business integration, and that they pursue new market development strategy and operation efficiency strategy. These results provide us the foundation that the determinants that we have analyzed can impact the supply chain integration strategies which take into account the competetive environments.
