Abstract: Abstract This paper analyzes the international patent status of subsea production equipment via aspects of the general trend of patent, patent country distribution, IPC structure and main patent applicants, etc., and put recommendation of technology R&D and industry development of subsea production equipment under the patent analysis. The analysis results show that international patent technology of offshore oil equipment has already been maturing. The United States, the United Kingdom, WIPO and Canada are the power countries of the patented technology of subsea production equipment with much more accumulated patents and maintain growth trend of patent applications. In particular in recent years, patent applications of subsea production equipment have rapidly increasing trend which indicates the arrival of a new round of technological revolution.
