Abstract

Literature retrieval

data extraction and quantitative analysis on patent documents in the field of global titanium alloy precision casting were carried out

aiming at understanding the status of intellectual property rights in the field. From the perspective of overall overview

technology analysis

key patent analysis and patent legal status analysis

the patent of global titanium alloy precision casting was revealed

presenting the development trend of global titanium alloy precision technology. The results show that China and Japan have a large number of patent applications

and attention should be paid to the technological progress of Chinese and overseas enterprises. Patent protection need to focus on technical topics such as oxide ceramic shell

centrifugal casting and investment casting.
