ABSTRACT

The invalid patents associated with schistosomiasis control were retrieved in the Chinese Patent Database of China National Intellectual Property Administration, the Baiten database and the incoPat database, and the overall trends, legal status, types, patent indexing and technical fields of all retrieved invalid patents were analyzed. As of December 30, 2020, there were totally 859 patents relating to schistosomiasis control, and 512 were invalid patents, with an invalid rate of 59.6%. The number of patent applications and invalid patents peaked in 2018, including 71 patent applications and 53 invalid patents. Among the 511 schistosomiasis control-related invalid patents with complete records, there were 425 invention patents, 81 utility model patents and 5 design patents, and 219 patents (42.9%) were invalid due to the termination of the patented right and 292 (57.1%) due to loss of the right for patent applications. The major technical points included medicines (chemicals), basic research, devices and detections, and the specialized fields were mainly concentrated in A61P33, G01N33, C12N15, C07K14 and A01N65. Our data demonstrate a high invalid rate of patents relating to schistosomiasis control in China. Secondary development and mining of the invalid patents in relation to schistosomiasis are recommended to make use of their values in the national schistosomiasis elimination program of China.

ABSTRACT

Objective To understand the knowledge,usage,applicability of the standard and the suggestions on the imple-mentation of Criteria for Control and Elimination of Malaria(GB 26345-2010)among malaria prevention and control staff of disease control and medical institutions at all levels in Yunnan Province,so as to provide the evidence for the implementation and revision of the standard.Methods Malaria prevention and control workers at 192 institutions in 16 prefectures and cities of Yunnan Province were surveyed.The malaria prevention and treatment workers at county-level center for disease control and pre-vention(CDCs),county-level medical institutions and township hospitals in Tengchong City and Yingjiang County of Yunnan Province were investigated on the spot.The knowledge and usage,problems and recommendations encountered in the implemen-tation of the standard were collected.Results Totally 444 questionnaires were collected,of which 428 were valid and the valid rate of questionnaires was 96.4%.Among them,the proportion of those who knew the standard was 86.7%(371/428),and the channel of knowledge acquirement was mainly the education and training,accounting for 50.7%(188/371).The total awareness rate of objective indicators in the standard content was 65.9%(282/428).Among the frequency of utilization,the "occasional use" of this standard was the majority,accounting for 33.6%(144/428).Among the applications,the highest proportion of ap-plying to the "regular malaria prevention and control work" was 59.3%(191/322),and only 19.3%(62/322)applied to the "as-sessment for malaria elimination".In the standard suitability assessment,the proportion of considering the standard to be fully applicable was 91.3%(391/428),and the proportion of considering the standard to be revised was 8.7%(37/428).The agen-cies where the respondents were located have taken corresponding measures to promote the implementation of the standard.A to-tal of 43 proposals for the implementation of the standard were collected,relating to personnel and supporting conditions.Con-clusions Combined with the actual situation,the standard should be strengthened practically.At the same time,the standard learning,training,and publicity should be strengthened to raise the implementation level.Its implementation in Yunnan Prov-ince should be sequentially consolidated and steadily promoted.
