国内外钛材专利技术分析

Analyzing of Titanium Patents at Home and Abroad

结合定量和定性的专利分析方法,对全球钛材专利技术的整体趋势、技术构成和技术发展趋势做了统计分析。结果表明:2005年至今,全球钛材领域专利申请数量处于较快增长中,该类技术处于生长发展期。在全球的钛材专利数量中,中国钛材专利数量占据一半以上,国外重要钛材生产企业的钛材专利申请数量并不是最多的,与国外采取了技术保密措施维护其技术优势有关,国内院校钛材专利技术的申请数量较大。

The statistical analysis for rolled titanium＇ s the overall trend, technique construction and tech- nological tendency over the whole world has been processed combining with patent analyzing methods of quantitative analysis and qualitative analysis. The number of roiled titanium＇ s patent application over the whole world has been increasing fast from 2005 till now, and such technology is in the growth stage. The number of Chinese rolled titanium patents takes more than half a part in the world. The patent quantity of key foreign rolled titanium production enterprises doesn＇t taking the most part, implying they keep their technique secret to retain their technique advantage. The most rolled titanium patents are applied by colle- ges and universities in China.
