In terms of patent authorization, the global patent authorization for high-speed rail industry increased year by year from 20 10 to 20 19, and began to decline in 2020. In 2020, the number of patents granted in the global high-speed rail industry will be 1629, accounting for 57. 18%.
202 1,1-1,the number of patent applications and patents granted in the global high-speed rail industry are 798 and 138 respectively, and the proportion of patent grants is only 17.29%. By the end of 20021,1.3, the number of patent applications in the global high-speed rail industry was 1.33 million.
Note: ① Patent authorization rate indicates the efficiency of application and the success rate of final authorization application.
② Statistics: If the patent application of 20 12 is authorized on 20 14, the authorized patent will be displayed in the patent application of 20 12.
(3) the legal status of patents: the number of "effective" is high.
At present, the global high-speed rail patents are in the status of "pending trial" and "valid", and the total number of high-speed rail patents is 3,959 and 9,362 respectively, accounting for 30% and 70% of the global high-speed rail patents.
(4) Market value of patents: the total value is close to 400 million dollars, and the number of patents below 30,000 dollars is relatively large.
At present, the total patent value of the global high-speed rail industry is $395 million. Among them, the number of high-speed rail patent applications under $30,000 is the largest, with 1.400; Followed by 300,000-300,000 US dollars of high-speed rail patents, a total of 2,505 patents were applied. The number of high-speed rail patent applications above $3 million is the least, with 3 applications.
Statistical caliber: make statistics according to the duplication elimination rule of a patent representative in each simple family, and select any patent with patent value in the same family to display.
2. Patent technology types of global high-speed rail industry
(1) Patent type: invention patents account for more than half.
From the perspective of patent types, there are currently 7,605 high-speed rail patents in the world as invention patents, accounting for the largest number of high-speed rail patent applications in the world, accounting for 57%. The number of utility model high-speed rail patents granted is 57 16, accounting for 43% of the global high-speed rail patent applications.
(2) Technical composition: the first technology accounts for more than 20%.
From the technical composition, the current "E0 1D 19/00"
Bridge Parts [2006.0 1] "The largest number of patent applications is 4 15, accounting for 3. 12% of the top ten technology applications. Followed by "C02F 1/00"
The treatment of water, waste water or sewage takes precedence over C02F3/00 to C02F9/00) [3] [2006.05438+0] ",with 393 patent applications, accounting for 2.95% of the top ten technical applications.
(3) Technical Focus: Ten Hot Spots
The top ten technical terms of high-speed rail in the world include rail transit, fixed frame, graphene, platform door, assembly, control system, robot, connecting plate, measuring method and friction material. Further subdivided, the hot words of high-speed rail technology include high-speed railway, high-speed train, detection system, pantograph, fixed plate and so on. Details are as follows:
Note: The keywords in the inner layer of sunrise map are extracted from the recent 5,000 patents. The keywords in the outer layer are the further decomposition of the keywords in the inner layer.
(4) Top-level patents cited: The two major patents are cited less frequently.
Test Method for Noise Source Identification of High-speed EMU (patent number: CN 103630232A) and Pile-slab Structure of Four-line Ballastless Track Subgrade (patent number: CN204644799U) are two high-speed railway patents that have been cited the most times, both of which have been cited for more than 25 times. The other ten patents cited are as follows:
3. Patent competition of global high-speed rail industry
(1) Distribution of technology source countries: Most of them are from China.
At present, China is the world's largest source of high-speed rail technology, and the number of high-speed rail patent applications in China accounts for 99.52% of the total number of high-speed rail patent applications in the world; Followed by Japan, Japan's high-speed rail patent applications accounted for 0. 17% of the global high-speed rail patent applications. The United States and Germany account for 0. 13% and 0. 14% of the global high-speed rail patent applications, respectively, which is far from China.
Statistical description: ① Make statistics according to the rule that each application displays a public text, and select the latest text of the public date for calculation. (2) According to the statistics of the country with patent priority, if there is no priority, it shall be calculated according to the country where the patent is accepted. If there are more than one priority country, it shall be calculated according to the earliest priority country.
(2) Distribution of patent applications in China: Jiangsu has the largest number.
In China, Jiangsu is the province with the largest number of high-speed rail patent applications in China, and the total number of high-speed rail patent applications is 1876. At present, the number of high-speed rail patent applications in Beijing and Sichuan both exceeds 1 000. At present, the top ten provinces in China are Shandong, Guangdong, Hubei, Zhejiang, Shanghai, Hunan and Henan.
