Chinese patent application status

There are in Chinese patent database 209 patent application relates to materials and surface modification of medical grade titanium alloy body medical fields, including domestic applicants (including Hong Kong, Macao and Taiwan) 188 patent applications, foreign patent applicant patent applications 21. Development trends in the Chinese patent application, the number of applications for domestic applicants accounted for the majority of total applications, and the number of applications showed a rising trend, from 2008 to 2009 financial crisis did not cause the recession enterprises decreased emphasis on intellectual property rights, on the contrary, an increase in the number of applications proved enterprises to improve the degree of importance of intellectual property. China submitted a patent application to foreign companies, mainly from Sweden, the United States and Germany and other countries, of which 3% of the total filings in Sweden, 2% of the total US filings, relatively few applications in other countries. Foreign applicants have not carried out a medical patent portfolio in the field of China's titanium, domestic applicants should seize the opportunity to increase research and development in the field of medical titanium alloy, and make patent portfolio.

Global patent application status quo

A total of 1362 relates to the field of surface modification of medical materials and bulk titanium patent applications in European patent database. Medical Titanium appeared earlier patent applications, but the number of applications of slow growth, and in 1993, 2003, 2007 to 2009 peak emerged. The reason is mainly due to new technology at different stages of development will encounter bottlenecks in the development, to solve the bottleneck problem in the number of patent applications will surge. Overall, the number of patent applications increasing medical titanium alloy, titanium medical research institutions in the field of investment is also increasing. States have submitted a patent application in the field of medical titanium alloy, the number of applications for the top six countries were the United States, Sweden, China, Germany, Japan, Switzerland, but the gap between the former six small, indicating that various countries have research and development are very seriously. Chinese applicants filed patent applications accounted for 15% of total patent applications, ranked No. 3, and No. 1 in the United States and Sweden or less, indicating that China rapid development momentum in the field of medical titanium. Due to the presence of biocompatible titanium medical, biological activity, corrosion resistance, wear resistance, mechanical properties and other characteristics in practical applications, in order to improve the performance of the above medical titanium alloy, mainly from the material body of technical means to begin to develop excellent properties of the new titanium; starting from the surface of the material, the use of various surface treatment methods for surface modification of titanium alloy, making it more suitable for medical applications.
