“…With the overall maintenance time of invention patents remaining relatively stable, longer examination time will limit the practical application of invention patents by patentees and is not conducive to the survival of invention patents. In addition, the examination time reflects a certain extent the examination efficiency of the examination authority on the uniqueness, novelty, and utility of the patent [21]. In the study of the number of inventors on the quality of patents, foreign scholar M.reitzing found that the number of inventors has a positive impact on the value of patents; while certain domestic scholars found that for various reasons, there are discrepancies between the actual inventors of patents in China and the inventors listed in the literature [22].…”

Based on the fact that the granted amount of patents in Chinese universities have increased significantly, we took the invention patents applied by universities in Sichuan Province from 2001 to 2015 as a sample and adopted Kaplan-Meier survival analysis and Cox proportional hazards model. We found significant differences in the survival time of invention patents in the three types of universities Based on this, we conducted an empirical study and comparative analysis on the factors influencing the survival time of the three types of universities. It was found that the number of citations and the number of patent families have different effects on the survival time of invention patents in the three types of universities; the examination time and the number of inventors have negative effects on the survival time of invention patents in the three types of universities; the number of claims, the number of IPCs and the number of forward citations have positive effects on the survival time of invention patents in the three types of universities. This paper can provide some reference for universities to cultivate high-value patents.

“…Agricultural patents ensure the rights of and innovators and applicants to exclusive, use and disposal of inventions and achievements in agricultural sectors for a certain period (Baumgartner 2006;Blakeney 2016). Such intellectual property institution not only facilitate the progress of agricultural science and technology innovation (Liu et al 2014;Song et al 2022), but also promote agricultural development (Schimmelpfennig and Thirtle 1994;Baumgartner 2006; Ang et al 2013). China filed 628,300 patents for agricultural inventions in 2017-2021, ranking first among 22 agriculturally advanced countries and accounting for 55.4% of the total number of inventions filed .…”

Development of science and technology is one of the vital driven forces for the Chinese agricultural development. Based on 2,513 valid potato invention patents from 1986–2019 in China, a social network analysis is applied to investigate the effects of network changes of potato patents on the innovation activities and potato production. The results show that China has formed a status quo of separation between potato producing areas and patent invention places. Collaborative relationships of potato patents mainly distribute in the non-main production areas. Most of the collaborations are intra-provincial rather than inter-provincial. The correlation relationship between potato innovation and potato yield is positive. But the density and cluster coefficient of collaborative networks in potato research affect the potato innovations differently. Considering the variation of collaborative network and different technology progress in potato production across regions, a cross-regional exchange platform is needed to promote the dissemination and promotion of potato patents in the main potato producing areas.

“…Patents often contain huge technical and commercial values. According to the statistics of the World Intellectual Property Organization, 80% of global inventions and technical knowledge can be traced back to patent literature, and more than 90% of the world's innovation information originates from patents [9,10]. In recent years, more and more experts and scholars have analyzed the capacity, efficiency, and status of scientific and technological innovation and transformation based on patent indicators and data.…”

In the process of responding to major public health emergencies, the transformation of emergency scientific research results often faces many unfavourable factors such as limited resources, tight time, changes in needs, and lack of results. It is necessary to evaluate and analyze the ability to transform emergency scientific research results under public health emergencies, so as to rationally allocate emergency scientific research resources between subjects and regions, improve the efficiency of emergency results transformation, enhance emergency scientific research capabilities, and efficiently support incident prevention, control, and treatment. Starting from the patent level, this paper constructs an indicator system to evaluate the transformation ability of emergency scientific research results under major public health emergencies. It improves the minimum distance-maximum entropy combination weighting method to realize the static evaluation of transformation ability for emergency scientific research results from the perspective of patents, then constructs the dynamic evaluation model of transformation ability for emergency scientific research results in public health emergencies from the perspective of patents, and carries out the dynamic evaluation of the emergency scientific research achievements transformation ability of different subjects and different regions. We also improve the ER index, measure the static polarization effect of the transformation ability for regional emergency scientific research results, and consider the time factor to construct a dynamic polarization effect measurement model for the transformation ability of emergency scientific research achievement. Furthermore, this paper improves the measurement model of contribution degree to the polarization effect, and analyzes the contribution degree to polarization of the transformation ability for regional emergency scientific research results.
