Abstract： Through the professional retrieval, data extraction and classification analysis of the global shape control patents
of titanium cast titanium alloy, the overall situation of the global shape control patents of titanium cast titanium alloy was
discussed. The patent application time and geographical distribution of shape control of cast titanium alloy, patent
application institutions and technology composition, key patents, highly cited patents and congener patents were analyzed,
and the global patent trend of shape control of cast titanium alloy was revealed. The results show that there are a large
number of patent applications for shape control technology of cast titanium alloy in China, patent application institutions
are concentrated in research institutes, and technical topics are focused on bio-titanium alloy, golf ball head, titanium alloy
blade, etc.
