Technology Mapping of the Underwater Sensor Networks by Patent Documents Using Two Commercial Software

- In order to evaluate the technologies related to underwater sensor networks were used two commercial software: PatBaseMR (MinesoftMR) and Matheo Patent XEMR. These technologies are essential to collect oceanographic data, with various applications, e.g., seismic predictions, offshore oil and gas, control of water quality and studies of the interactions between the oceans and atmosphere. There were selected 85 patent documents related to underwater sensor networks between 2000 and 2011. The temporal evolution revealed a strong growth from 2006. Further, it was observed that the main offices where the patent documents have been deposited are: (a) of China (SIPO), (b) of South Korea (KIPO), and (c) of the United States (USPTO).
