Objectives : We have examined and analyzed patents regarding acupuncture point stimulating methods in order to understand the stimulation technology and research trends of acupuncture points. Methods : We searched and analyzed the total of 135 on-line DB based patents under time limit of Dec, 2010. Results : According to the analyzed results, non-invasive method is used more than invasive method. Electric stimulation is used more than any other method, such as magnetic, ionic, laser, light, ultrasonic, water, Far IR and thermal stimulation. There are numbers of cases such as rejected during screening procedure, waived before the screening, of failed to renew its registrational status which outnumber those patents registered and maintained. Conclusions : These data suggest that we need to move away from using one side method such as non-invasive and electrical method. Thus follow-up service is recommended.

A patent contains detailed information of the developed technology and is published to the public. Thus, patents can be used to overcome the limitations of traditional technology trend research and prediction techniques. Recently, due to the advantages of patented analytical methodology, IP R&D is carried out worldwide. The patent is big data and has a huge amount, various domains, and structured and unstructured data characteristics. For this reason, there are many difficulties in collecting and researching patent information. Patent research generally writes the Search formula to collect patent documents from DB. The collected patent documents contain some noise patents that are irrelevant to the purpose of analysis, so they are removed. However, eliminating noise patents is a manual task of reading and classifying technology, which is time consuming and expensive. In this study, we propose a model that automatically classifies The Noise patent for efficient patent information research. The proposed method performs Patent Embedding using Word2Vec and generates Noise seed label. In addition, noise patent classification is performed using the Random forest. The experimental data is published and registered with the USPTO among the patents related to Ocean Surveillance & Tracking Network technology. As a result of experimenting with the proposed model, it showed 73% accuracy with the label actually given by experts.

This study deals with the analysis of a technology convergence of the IoT(Internet of Things) which is the key technology of the fourth industrial revolution. For this purpose, 77 patents with the Main Category CPC code G06Q50/10(Electronic Commerce Service) among the IoT patents filed after 2014 were analyzed. As a result of the Main-Sub Category analysis of CPC codes, the IoT has a strong relationship between "Electronic Commerce Service (G06Q50/10)" and G06Q(49 cases), H04L(40 cases), G08B(24 cases), G05B(21 cases), H04W(21 cases), H04N(16 cases), and so on. By using the methodology in this study, we can contribute the establishment of technology strategy and new value creation from the prediction of the possibility of the combination of technologies and to develop new patents among various new technologies.

As the fact that science is the driving force behind technological development and that technological innovation contributes to economic development has been proved empirically convincing, the interaction between science and technology is highly emphasized in advanced countries. But, Korea has not been active in conducting research on science-based technological development and on the scientific fields that have strong relationships with Korean technology. This study attempts to explore the influence of scientific research papers cited in US patents by Koreans on other US patents and identify the interactions between scientific research papers and patents, by examining the scientific references cited in the Korean-originated US patents.

Native plants thrive naturally in specific areas without human intervention, offering significant potential as genetic resources and biotechnological assets across multiple sectors. To harness this potential, our focus was on analyzing domestic patents related to native plants, investigating their uses, effectiveness, active components, and extraction methods. Using the Korea Forest Service's National Standard Plant List, we gathered data from 988 patents on native plants and 430 patents on the use of native plant seeds. This comprehensive patent analysis aimed to reveal research patterns, technology levels, and emerging trends. The goal is to identify research trends, current technology levels, and provide insights for future patent applications involving native plants.

Very closely related to technologies, patents, standards, and licensing interact with them, cores of technology innovation, as the technology diffusion media for technology innovation. Todays it is usually impressed that no one can face to international technology competetion environment without the strategy of patent, standardization, and licensing. In this paper, the whole configuration of technology innovation is represented including the patent, standard, licensing as these media, their basic characteristics and how they roles as technology diffusion media interacting with the technology, core of the technology innovation configuration are analyzed, and some related practical cases to be understood as the applications of these three media for technology innovation are also explained : such as IMT-2000 and CDMA technology which have been international issues currently involved in patents and standardization together, the advent of Linux operating system being the new event in the field of computer technology. Finally this paper intends to have the implicated meanings needed for national policy improvement, through appreciating the importance and the mechanism of roles of three media factors for technology innovation.

Patent classification is becoming more critical as patent filings have been increasing over the years. Despite comprehensive studies in the area, there remain several issues in classifying patents on IPC hierarchical levels. Not only structural complexity but also shortage of patents in the lower level of the hierarchy causes the decline in classification performance. Therefore, we propose a new method of classification based on different criteria that are categories defined by the domain's experts mentioned in trend analysis reports, i.e. Patent Landscape Report (PLR). Several experiments were conducted with the purpose of identifying type of features and weighting methods that lead to the best classification performance using Support Vector Machine (SVM). Two types of features (noun and noun phrases) and five different weighting schemes (TF-idf, TF-rf, TF-icf, TF-icf-based, and TF-idcef-based) were experimented on.

This study proposes a method for investigating current patents related to information communication technology and smart mobility to provide insights into future technology trends. The method is based on text mining clustering analysis. The method consists of two stages, which are data preparation and clustering analysis, respectively. In the first stage, tokenizing, filtering, stemming, and feature selection are implemented to transform the data into a usable format (structured data) and to extract useful information for the next stage. In the second stage, the structured data is partitioned into groups. The K-medoids algorithm is selected over the K-means algorithm for this analysis owing to its advantages in dealing with noise and outliers. The results of the analysis indicate that most current patents focus mainly on smart connectivity and smart guide systems, which play a major role in the development of smart mobility.

We investigated and analyzed the technological landscape of the global pet food industry, focusing on related industries in Korea and abroad. This industry accounts for the largest share of the rapidly growing global pet market. We aimed to identify and develop technologies that can strengthen Korea's position in this market. Our study employed various quantitative methods, including time series analysis, country and applicant analysis, and International Patent Classification (IPC) technology analysis. These analyses allowed us to objectively assess the current technological status, patent application distribution, and technological trends in the pet food industry. Our findings revealed that the United States currently holds the leading position in terms of patent applications within the pet food industry. This suggests that to establish a differentiated competitive edge in this field, it's crucial to develop technologies with high usability and target specific segments within related industries. Additionally, focusing on interdisciplinary research that combines Korea's existing advanced technologies with other relevant fields is essential.
