Abstract

Geophysical prospecting technologies are employed to environmental site assessments and monitoring, subsurface investigation, geologic hazard monitoring since they are able to provide information and imaging regarding the subsurface. In this study, we carried out several analysis on patent documents for the geophysical prospecting technologies. The patents including abstracts, claims and drawings from 1976 up to 2005 were surveyed and 904 patents were collected finally. The patents were investigated as to countries, years, assignees and technologies. Furthermore, we carried out the comparative analysis for technological level of assignee countries with United States patents. The top 5 assignee countries are United States, United Kingdom, Japan, Norway and France. Especially United States and United Kingdom play important role in this area as holding 663 patents.

물리탐사는 측정점에 대한 정보에만 국한하는 다른 조사방법과는 달리 지반내부에 대한 영상 및 정보를 제공할 수 있으므로 환경오염부지 평가 및 감시, 지반조사, 지질재해 등에서 중요한 기술로 활용되고 있다. 본 연구에서는 상기물리탐사 요소기술에 관한 특허분석을 실시하였다. 1976년부터 2005년까지 출원된 특허의 요약문, 청구항, 도면 검색 등을 통해 총 904건의 관련 특허를 추출하였다. 추출된 특허를 대상으로 국가별, 연도별, 출원인별, 그리고 기술 분야별 출원동향을 분석하였다. 또한 미국특허 분석을 통해 국가별 기술수준을 비교 분석하였다. 상위 5위의 출원국가는 미국, 영국, 일본, 노르웨이 그리고 프랑스 순이었으며, 특히 미국과 영국 출원인의 특허건수가 663건(73.3%)으로 이 분야 기술개발을 주도하고 있는 것으로 파악되었다.
