Patent Briefing of Dalian University of Technology in the first half of 2022

Recently, Dalian University of Technology Patent Briefing (January to June 2022) was released by Dalian University of Technology Intellectual Property Information Service Center (Library). Through the 2006 patents announced by the school in the first half of 2022, it revealed the patent situation from January to June 2022 from Dalian University of Technology.

Table 1: Patent Overview of Dalian University of Technology from January to June 2022

1. Overview of patent data

The report shows that incopat and Innography are used for patent retrieval, and the retrieval results are screened and sorted out to obtain the patent overview of Dalian University of Technology from January-June 2022. According to the information in the table, a total of 2006 patents were announced from January to June 2022. Among them, there are 1806 patents, 126 US patents, 43 patents of the World Intellectual Property Organization (WIPO), 11 Japanese patents, 6 Australian patents, 5 Patents of the European Patent Agency (EPO), 4 patents in South Africa, Canada and Canada and Canada and Canada and Canada and Canada and Canada and Canada and Canada and Canada and Canada and Canada and Canada and Canada Russian patents each and 1 Dutch patent. Among China's patents, 768 were invented, 937 applications for inventions, 97 practical new types, and 4 appearance design.

2. Analysis of the technical field (IPC classification)

The report pointed out that the analysis of the technical layout of the patent of Dalian University of Science and Technology from January to June 2022 is shown in Figure 1. The figure uses different colors to identify IPC classification (small category) and use the rectangular area to identify the number of patents. According to the information in the figure, the status of IPC categories that have more layouts from January to June 2022 from 2022 are as follows: 190 pieces of G06F (electric digital data processing), accounting for about 9.47%; Physical properties test or analyze materials) 171 pieces, accounting for about 8.52%; G06N (computer system based on specific computing models) 134 pieces, accounting for about 6.68%; 125 pieces, accounting for about 6.23%; G06K (data identification; data representative; record carrier; processing carrier processing) 95 pieces, accounting for about 4.74%.

3, 3D patented sand table

The report shows 3D patented sand tables (Figure 2-1, Figure 2-2). 3D patented sand table is a patented strategic analysis method, which can quickly focus on the hotspot of the patent layout. Through the clustering function of the 3D patented sand table, the patent technology competition situation can be displayed. Among them, the peak represents the technical dense area and the valley represents the blank point of technology. The analysis of the analysis of the patent 3D patent sand table from January to June 2022 of Dalian University of Technology is shown in the figure below. The figure uses different colors to identify the patented IPC classification (department), and use purple diamond to identify a high value patent. According to the information in the picture, it can be seen that from January to June of Dalian University of Science and Technology from January to June 2022, more than 200 research technologies were sorted according to the number of patents: "Visible light image/deep learning/loss function" (469 pieces), "sports skate/ Gradually open model/processing power "(294 pieces) and" catalyst/lithium sulfur battery/molecular sieve "(275). In addition, according to the 3D sandbox direction, it can be found that the patent layout of Dalian University of Science and Technology has a relatively obvious technical direction distinction, and the technical layout of each direction is densely dense and the peaks are obvious, showing a very obvious team advantage.

Patent is an important part of scientific research results. It is an important intangible asset. The number and quality of patents on the one hand reflect the innovation ability and scientific research level of scientific researchers, and it is also a manifestation of the function of serving the national science and technology, economic and social development. The Intellectual Property Information Service Center of Dalian University of Technology was officially established in June. As the internal institution of the library, since its establishment, relying on the rich literature resources of the Library of Dalian University of Technology, it is committed to serving teachers, teams, and college sciences Studies, provide patent literature search and analysis services to readers inside and outside the school.
