Technological Profile of Microreactor Based on Patent Analysis

AbstractSince the concept of microreactor was first proposed in the 1980s, it has been entering the chemistry and chemical engineering fields at a high speed and is favored by both scientific and commercial fields. The development of microreactors has been extensively studied in the literature, but less analysis has been carried out from the perspective of industrial technology. This paper aims to identify, analyze, and map the technological profile of microreactors from the perspective of patents. Based on the text mining techniques, a quantitative analysis of 16,327 microreactor‐related patents in the Derwent Innovations Index database was conducted. The analysis reveals a consistent annual increase in the number of microreactor‐related patents from 1982 to 2021. Specifically, China emerges as the leading country in terms of patent disclosures, whereas the United States and the World Intellectual Property Organization (WIPO) play a crucial role in knowledge transfer. Moreover, this study identifies the technological evolution path for microreactors and analyzes in detail the key patents along this evolution path. Individuation, modularization, and greening are the developing directions of microreactor technology in the future. This research offers valuable guidance for researchers and industry professionals in decision‐making and driving advancements in microreactor technology.

Trace the evolution path of pharmaceutical wastewater treatment technology based on a patent perspective

ABSTRACT This paper discusses the research hotspots and future development trends of pharmaceutical wastewater treatment technology, in order to provide valuable reference and guidance to promote the development of technology. First, the search path counting (SPC) algorithm is utilized to identify the global main path to perform a preliminary analysis of the technology evolution path from a macro perspective. Second, according to the life cycle, S-curve divides the time windows of the temporal themes and uses the Latent Dirichlet Allocation (LDA) modeling to identify the themes under each time window. Then, a visualized Sankey diagram is generated to determine the evolutionary relationship, which can be supplemented with the paths of technological evolution from the micro point of view. Finally, six research hotspots of pharmaceutical wastewater treatment technology were found, which are compounding agents, advanced oxidation technology, nanomaterials, artificial intelligence (AI) technology, membrane pollution prevention, and various combinations of wastewater treatment technology. The study also predicted its future development direction.

Estimating patent value in the United States and Japan

Patents contribute to economic development; therefore, estimations of patent value are significant in measuring their impact on the economy. With this in mind, this article discusses estimations of patent value with the renewal model developed by several economists. Targeted patents are those issued in the United States and Japan from 1990 to 2010. In addition, the study examines patent values for several technology fields and considers which technology field should be the focus for the United States and Japan. Moreover, this article compares estimations based on the renewal model versus those based on other data such as sales, trade prices, or trials and analyzes how close this model's estimations are to the real values. This article's results demonstrate that the renewal model is useful for evaluating patents overall and analyzing technological trends from a patent perspective.

Research on the evolution of China's photovoltaic technology innovation network from the perspective of patents

Photovoltaic (PV) technology, as a low-carbon energy technology, is crucial to mitigating climate change and achieving sustainable development. China has the largest total number of PV technology patents in the world, but the lack of core technologies has restricted the further innovative development of China's PV industry. Therefore, it is necessary to clarify China's current PV technology accumulation to better catch up with key technology areas. To clearly describe the structural characteristics of China's PV technology innovation network, this study uses China's patent PV technology data over the past 20 years from the Incopat global patent database and analyses the structural characteristics of the network from the perspectives of one-mode and two-mode networks, using method of social network analysis (SNA). The results show that 1) the leading PV enterprises have basically formed relatively stable internal collaborations and that the scale of innovation network development has expanded rapidly, with very strong stamina; 2) with the development of China's PV industry, many innovative PV techniques have been developed by leading enterprises in the field of innovation and research and development (R&D) of PV technology, and among patent applicants with strong collaboration, kinship collaboration with investment relationships is dominant; 3) provinces participating in PV technology innovation are increasing significantly, the network is more influenced by leading nodes, and the eastern coastal provinces are pioneers in the innovation and R&D of PV technology; and 4) PV technological innovation collaboration between patent applicants and cities has changed from local collaboration to cross-regional collaboration, high-value areas are basically concentrated in the eastern coastal region of China, with scattered spatial characteristics, and cross-regional collaboration presents a “triangular” spatial structure, with the Yangtze River Delta, Pearl River Delta, and Beijing-Tianjin-Hebei as cores. The conclusions can provide patent information support for scientific research on energy conservation and emission reduction to achieve low-carbon goals, and can also provide reference for policy formulation of renewable energy development and green development strategies.

Identification of Product Innovation Path Incorporating the FOS and BERTopic Model from the Perspective of Invalid Patents

Under the premise of resource constraint, it is crucial to identify the product innovation opportunities contained in failed patents through external search in order to compensate for the shortcomings of enterprises’ own technology. Due to the cost of patent research and development and the risk of infringement, this paper constructs a product innovation identification path that integrates the FOS and BERTopic model from the perspective of invalid patents. The path consists of three stages, including the identification of the problem to be solved by the product based on functional analysis, the extraction of the subject matter elements based on the core failed patent technology, and the generation and evaluation of innovative solutions based on TRIZ theory and the best- worst method (BWM). Finally, the feasibility of the path constructed in this paper is verified by taking a slurry pump as an example. The application results show that the product innovation identification path constructed in this paper can provide theoretical support for enterprises to carry out technological innovation activities efficiently.

Development Pattern of Medical Device Technology and Regulatory Evolution of Cataract Treatment

To prevent regulation from becoming an obstacle to healthcare technological innovation, regulation should evolve as new healthcare technologies are developed. Although regulation is closely related to healthcare technology development, there are few studies that view healthcare technological advances from the multi-layered perspective of papers, patents, and clinical research and link this with regulatory evolution. Therefore, this study tried to develop a new method from a multi-layer perspective and draw regulatory implications based on it. This study applied this method to intraocular lens (IOLs) for cataract treatment and detected four major healthcare technologies and two recent healthcare technologies. Moreover, it discussed how current regulations evaluate these technologies. The findings provide implications for healthcare technological advances and the evolutionary direction of regulation through the example of IOLs for cataract treatment. This study contributes to the development of theoretical methods for co-evolution with regulations based on healthcare technology innovation.

Low-carbon spatial differences of renewable energy technologies: Empirical evidence from the Yangtze River Economic Belt

Under the “double carbon” target, renewable energy technologies offer a new low-carbon development path for human society. This paper selects the Yangtze River Economic Belt as the research area, introduces the classification of the renewable energy technologies from the perspective of patents and uses the Super-SBM model, entropy TOPSIS method and spatial Durbin model to empirically analyze the spatial spillover effects of the renewable energy technologies on carbon emission efficiency (CEE) and optimal development range. The analysis conclusions are as follows: First, there are differences in geographical location and geographic distance between the eastern and the western regions. The CEE is spatially correlated, but the permeability is weak, which specifically reflects the stepwise difference in the eastern, central and western regions of the spatial dimension and the path correlation in the time dimension. Then, the effects of the renewable energy technologies on CEE are all positive, showing continuous and effective positive promotion effects, but the performance of technology diffusion is poor, the spillover effect on the adjacent regions is not obvious. And finally, the positive promotion effect of the renewable energy technologies on CEE is affected by the interval of its double threshold effect.

Classification of FinTech Patents by Machine Learning and Deep Learning Reveals Trends of FinTech Development in China

The development of the financial industry and its integration with information technology have promoted FinTech innovation. China is a major contributor to FinTech innovation, but few studies have systematically summarized FinTech innovation and development in China from the perspective of patents. This lacuna is attributable to the lack of a generally accepted classification of FinTech patents and the unavailability of classified Chinese FinTech patent text data. To fill this research gap, we developed a classification of Chinese FinTech patents and manually annotated a set of patent texts to train machine learning and deep learning models to classify massive Chinese patent application data and identify different types of FinTech innovations. Among the evaluated models, the character-level convolutional neural network (CNN) model and BERT model classified FinTech innovation most accurately. We used the character-level CNN to classify 20,529 Chinese FinTech patent applications from 2013 to 2020. The classified dataset was used to briefly analyze the history of FinTech innovation development in China and its future prospects.

Examining Key Technologies Among Academic Patents Through an Analysis of Standard-Essential Patents

With the growing focus and development on the industrialization of the research and development (R&D) outcomes of universities, academic patents have witnessed significant growth in recent years. However, previous development directions for the technologies of academic patents have mostly focused on patents approved by or applied for with major patent offices; few have examined from the perspective of standard-essential patents (SEPs). This study examined key technologies of academic SEPs through network analysis. The findings revealed that most of the key technologies of academic SEPs are involved in wireless communication networks and the transmission of digital information, electric digital data processing, control or regulating systems, and secret communication systems. Among these, secret communication systems are key technologies in academia, and more scientific research resources should be invested in secret communication R&D in the future. In addition, the key technologies of academic SEPs have changed; specifically, image coding technology has undergone major developments. Accordingly, this study developed a key technology network model for academic standard-essential patents to verify those academic technologies that are vital to industrial applications.
