From 20 10 to 2020, the number of patent applicants and patent applications in the global blockchain industry are on the rise. Overall, global blockchain technology is in a period of rapid development.
Note: The life cycle stage of the current technology field is analyzed by the change of the number of patent applications and the number of patent applicants with time.
(2) The number of patent applications and authorizations: The number of patent applications and authorizations will decrease in 2020.
From 20 10 to 2020, the number of patent applications in the global blockchain industry is increasing year by year. In 2020, the number of patent applications in the global blockchain industry will be 14800.
In terms of patent authorization, the global blockchain industry patent authorization increased year by year from 20 10 to 20 18, and began to decline in 20 19. In 2020, the number of patents granted in the global blockchain industry is 20 17, and the proportion of patents granted is only 13.6%.
From 20021to1-August, the number of patent applications and the number of patents granted in the global blockchain industry were 4,537 and 324 respectively, accounting for 7.09% of the total amount granted. As of August 30, 20021year, the number of patent applications in the global blockchain industry was 43,000.
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: mainly "pending" patents.
At present, most of the global blockchain patents are in the status of "pending approval" and "valid", and the total number of blockchain patents is 310.2 million and10.05 million respectively, accounting for 73% and 24% of the global blockchain patents. The number of blockchain patents in the PCT formulation period is only 14 14, accounting for about 3% of the total blockchain patents in the world.
(4) Market value of patents: the total value exceeds 1 1 billion dollars, and there are many patents below $30,000.
At present, the total value of global blockchain industry patents is 1 1.3 1 billion dollars. Among them, the number of blockchain patent applications below $30,000 is the largest, with 32,800; The next is the blockchain patent of 300,000-300,000 US dollars, and the total number of patent applications is 38 10. The number of blockchain patent applications of $3 million is the least, with 50.
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. Types of patented technologies in the global blockchain industry
(1) Patent type: invention patents account for 96.67%.
From the perspective of patent types, there are currently 4 1.600 blockchain patents in the world as invention patents, accounting for the largest number of blockchain patent applications in the world, accounting for 96.67%. The number of utility model blockchain patents and design blockchain patents is 1279 and 153 respectively, accounting for 2.97% and 0.36% of the global blockchain patent applications respectively.
(2) Technical composition: the proportion of the first technology is nearly 15%.
In terms of technical composition, at present, the number of patent applications for "safety devices for protecting computers and their components, programs or data from unauthorized actions [8,2013.01] [2013.01]" is the largest, with104000. Followed by "devices, equipment, circuits and systems not included in H04L 1/00 to H04L27/00 [5] [2006.0 1]", the number of patent applications was 9,993, accounting for 14.05% of the total number of applications.
(3) Technical Focus: Ten Hot Spots
The top ten technical terms of global blockchain include smart contract, authentication method, power-saving equipment, integrity, database, computer, management system, blockchain network, digital signature and user terminal. Further subdivided, the hot words of blockchain technology include blockchain, blockchain technology, security, big data, management methods, computer equipment 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) Number of citations TOP patents: The top ten patents have been cited more than 1500 times.
Blockchain identity management system based on public identity book (patent number: US9635000B 1), asset trading platform and digital authentication and trading method of assets (patent number: CN 105956923A) are the two most cited blockchain patents, which were cited 262 times and 2 17 times respectively. The other ten patents cited are as follows:
3. Patent competition in global blockchain industry
(1) Distribution of technology source countries: China accounts for the highest proportion.
At present, China is the largest technology source country of blockchain in the world, and the number of blockchain patent applications in China accounts for 63.52% of the total blockchain patent applications in the world; Followed by the United States, the number of blockchain patent applications in the United States accounts for 15.44% of the total number of blockchain patent applications in the world. Although South Korea and China rank third and fourth, there is a big gap between them and China in the number of patent applications.
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 patent priority country, if there is no priority, it shall be calculated according to the country of acceptance. 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: Guangdong has the largest number.
In China, Guangdong is the province with the largest number of blockchain patent applications in China, with the cumulative number of blockchain patent applications reaching 848 1. The number of blockchain patents currently applied by Beijing also exceeds 6,000, and the number of blockchain patents currently applied by Zhejiang, Shanghai, Jiangsu and Shandong all exceeds 1 1,000. At present, Sichuan, Fujian, Hubei and Shaanxi are the ten provinces that apply for blockchain patents the most in China.
Description of statistical caliber: According to the address submitted by the patent applicant.
