| Abstract | Compared with the numbers of paten applications and patent granted, the numbers of valid patents and their maintenance times can better embody one country's technological innovation capability. In this paper, 2921 patents, which granted by the State Intellectual Property Office in China in 1994 and up to April 30, 2007 terminated due to unpaid fees, are analyzed based on the patent information perspective by multivariate linear regression using SPSS software (11.5). The results show that the average maintenance time of patents, which granted by the State Intellectual Property Office, is shorter and the terminated speed quicker. The effecting degrees of a nationality of applicants, a examination time, a types of patentees, a number of inventors and a claims number of patents on the paten maintenance time followed by weakening. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
