A technology is continuously developed in a rapidly changing global market. A company requires an appropriate R&D strategy for adapting to this environment. That is, the technologies owned by the company needs to be thoroughly analyzed to improve its competitiveness. Alternatively, technology classification using IPC codes is carried out recently in an objective and quantitative way. International Patent Classification, IPC is an internationally specified classification system, so it is helpful to conduct an objective and quantitative patent analysis of technology. In this study, all of the patents owned by company C are investigated and a matrix representing IPC codes of each patent is created. Then, a structured association map of the patents is made through association rules mining based on Confidence. The association map can be used to inspect the current situation of a company about patents. It also allows highly associated technologies to be clustered. Using the association map, this study analyzes the technologies of company C and how it changes with time. The strategy for future technologies is established based on the result.

Produced water from oil production processes is mostly composed of oily wastewater. So, it is important to extract and remove the oil components from the produced water environmentally and in utilizing water resources. Produced water treatment is classified as physical, biological and chemical method. The technology trend of oil treatment for produced water was analyzed based on patent application years, countries, main applicants, and each technologies.

It is very essential issue in industrial advancement and company survival for international standard body to adopt standards including ICT that domestic company or our country owns. Also, advanced countries fiercely contest in order to include domestic technology in international standard and make every effort to secure essential patent relating to core and basic technology in international standard. In this circumstances, it is necessary to develop standardization strategies and take systematic approaches in an attempt to upgrade our country to strongly knowledge-based country in 21th century and achieve a leading position in ICT market. Therefore, this paper will suggest systematic and comprehensive approaches from planning of technology development to securing essential patent of international standard and have the purpose of making standardization base as well as promoting international standardization of domestic technology.

In recent years, language model-based generative AI technologies have made remarkable progress. In particular, it has attracted a lot of attention due to its increasing potential in various fields such as summarization and code writing. As a reflection of this interest, the number of patent applications related to generative AI has been increasing rapidly. In order to understand these trends and develop strategies accordingly, future forecasting is key. Predictions can be used to better understand the future trends in the field of technology and develop more effective strategies. In this paper, we analyzed patents filed to date to identify the direction of development of language model-based generative AI. In particular, we took an in-depth look at research and invention activities in each country, focusing on application trends by year and detailed technology. Through this analysis, we tried to understand the detailed technologies contained in the core patents and predict the future development trends of generative AI.

Today, ubiquitous technology (e.g. computers or networked devices pervade everywhere we are) has enlarged by great advancement of information and communication technologies. If ubiquitous technologies is applied to, innovation of spatial information technology is expected. traditional spatial information technologies such as survey, GIS, GPS, LBS, and RS and ubiquitous technology gradual1y have been converged. The aim of this study is to create shared visions in spatial information technologies by scenario based roadmapping. So, we surveyed the state of the art in main spatial information technologies, market status and patent map. Consequently, prospects of spatial information technologies is suggested. The aim of 1st and 2nd NGIS project focused on map supplier was to develop digital map(e.g. framework data, various thematic map). As a result, the best technology of digital mapping is achieved in the world. But, there is not enough to develop GIS and LBS solution. Current market in GIS S/W and Telematics is about 384billon won and 250billion won. a patent is applied in the order, like a USA(1571case, 47%), Japan(883case, 26%), EU(478case, 14%), Korea(446case, 13%). In the future, spatial information technology fused on ubiquitous technology will be focused on user's demand and developing convenience context. The developing target will be realtime monitoring of 3D spatial data based on high resolution coordinate system, sharing and supplying multi-sensor data considered users demand, location service by ubiquitous technologies.

우리나라 정부는 공공연구기관에서 개발된 기술을 민간부문에서 사용을 극대화하여 기업 및 국가경쟁력을 제고하기 위하여 기술이전과 기술평가 및 기술정보유통 등의 기반을 확충하여 산업전반의 기술경쟁력을 강화하고 있다(기술이전촉진법 제정(2000. 1. 28). 이와 같은 변화는 국가경쟁력의 무게중심이 산업기반경제에서 지식기반경제로의 이동을 나타내는 것이며, 미국을 비롯한 선진 국가들의 움직임은 우리나라보다 10년 이상 앞선 상태이다. 지식기반경제에서는 특허의 전략적 활용이 가장 중요하게 여겨지고 있으며 각 연구기관 및 기업은 특허의 포트폴리오에 총력을 기울이고 있다. 그러나 특허의 사업화 가능성을 판단하여 우수 특허군을 분류하거나 특허의 등록유지에 관한 결정을 내릴 때 현재 특허실사 맵, Risk-Return chart, 전문가 심의 방법을 범용하고 있으나 이와 같은 세 가지 방법은 평가자 개인의 주관적 입장이 강하게 작용하고 있어 문제점으로 지적된다. 본 고에서는 기존의 특허실사 방법론의 맹점인 평가의 주관성을 배제하기 위하여 객관적이고 표준화된 정보인 특허를 사용하여 고안된 두 가지 특허지수(CPP, TCT)를 사용하여 객관적인 특허실사 방법을 제안하고 실증분석을 통하여 사용 가능성을 고찰해 보았다.

Using 23 867 standard essential patents claimed for three different wireless telecommunication standards (GSM, WCDMA, and LTE), this research examined the difference in technological importance and breadth of patents between practicing and non-practicing entities. We discovered that compared to manufacturers and service providers, organizations who do not appropriate innovation-derived profits directly from product or service markets tended to have relatively low-quality but broadly scoped technologies for the claimed standard essential patents. These relationships between the characteristics of inventions and the organizational types were consistently held across different generations of wireless standards as indicated by regressions run for each sample split by generation. Furthermore, the theory and policy implications of our results and arguments are presented herein.

개인화 된 특허 분류 시스템은 기존의 자동 분류 및 특허 문서의 특성, 그리고 분류 체계의 개인화를 고려하여 접근해야 한다. 본 논문에서는 개인화 된 특허 분류 시스템을 구축하는데 있어 개인화된 분류 체계 및 모델의 구축, 특히 분류체계 구축에 있어서의 자동화에 초점을 두었다. 우리는 특히 분류체계 구축 자동화에 있어 특허 문서의 기존 분류체계인 IPC 및 문서 클러스터링을 활용하였다. 다음으로 이를 기반으로 한 구축 시스템 사례를 들었다. 구축 후 나타난 정성적 문제점을 분석해보고, 분석 결과를 향후 연구 방향으로 삼고자 한다.

This paper identifies GNSS education and training program under Geomatic field of study. GNSS education programs is evaluated $vis-{\grave{a}}-vis$ new-products. Data on Geomatic knowledge generation in the era of the GNSS derivatives over the 1975 - 2003 period are examined. The emerging trends and patterns; in particular for selected Asian nations will be dissected in detail. The knowledge indicator used in this study is the patent ownership against the background of emergence of new core technologies and innovations in the field of GNSS. Looking at the dismal performance of Geomatic professionals in terms of innovative activities in most part of Asian and Malaysia in particular, is it there is something that holding up these professionals from doing so? With our universities and numerous polytechnics offering Geomatic program, more is expected from them. Is it a problem of lack or inadequacy of skills? Or is it these professionals are too busy and being narrowly focused on doing something else?

지식과 정보의 중요성이 강조되는 지식기반사회에서는 지식재산권의 대표적인 유형인 특허의 중요성이 날로 높아지고 있고, 그 수 또한 급증하고 있다. 특허 문서의 효과적 검색과 이용을 위해서는 새롭게 출원되는 특허 문서의 체계적인 분류 작업이 선행되어야 하고, 따라서 방대한 양의 특허 문서를 자동으로 분류해주는 시스템이 필요하다. 본 연구에서는 Doc2Vec 모델을 이용하여 국내 특허 문서의 특징(feature)을 추출하고, 추출된 특징을 바탕으로 한 특허 문서의 자동 분류 모형을 제안한다. 먼저 국내에 등록된 31,495 건의 특허 문서의 IPC(International Patent Classification)와 요약정보를 바탕으로 Doc2Vec 모델을 구축하였다. 구축된 Doc2Vec 모델을 통하여 훈련데이터의 특징을 추출한 후, 이 특징 벡터를 이용하여 분류기를 학습하였다. 마지막으로 Doc2Vec 모델을 이용하여 실험데이터의 특징 벡터를 추출하고 분류기의 성능을 실험한 결과, 43%의 분류 정확도를 얻었다. 이를 통해, 특허 문서 분류 문제에 Doc2Vec 모델의 사용 가능성을 확인할 수 있었다.
