Patent Analysis on Geophysical Prospecting Technologies
Correspondence to : Jung-Ho Kim
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.
