Abstract
Study of patent literature helps in understanding technological developments, on-going research and emerging trends in the area of geothermal energy. This paper makes use of the various patent quality indicators to obtain insightful information on the technology development. Patent searches were conducted covering patents filed in 71 countries using a combination of keywords related to geothermal energy and appropriate International Patent Classification (IPC) codes over the entire period through 2010. The screening of the search results helped identify patent records describing different value chain segments in geothermal energy. Patent value indicators and analytics were used to obtain key insights on technology developments in geothermal energy.
