Abstract
|
|
|
|
In this study, we analyzed the patent trends for chitin derivatives to reveal the main R&D directions, focusing on patents applied for and registered in Korea, the USA, japan, and Europe. A total of 9,286 patents were retrieved and 6,270 patents were selected for final effective analysis by data de-duplication and filtering. We classified the chitin derivatives applications into five categories and perform quantitative and qualitative analysis. And a port-folio analysis using the correlation between the number of patents and the applicants for each patents revealed a ‘medical and health-care’ as the key application with greatest growth potential. From an analysis of the barriers to patents being granted, we emphasize the need to avoid similar topics existing patents or patents applications and to develop differential technology. As a result, we can understand domestic technical level and research trends of advanced countries. And we provided objective patent information and we proposed the direction of the development and the way of the securing patent right.
