In terms of patent authorization, the number of patents granted in the global CPU industry increased year by year from 20 1 1-20 17, and began to decline in 20 19. In 2020, the number of patents granted in the global CPU industry is137.44 million, and the proportion of patents granted is only 48.35%.
From 20021to1-September, the number of patent applications and patents granted in the global CPU industry were 5657 and 776 respectively, accounting for 13.72%. By September 7th, 2002 1,1,the number of patent applications for CPU industry in the world was 2 1.04 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) Legal status of patents: the number of "valid" patents accounts for more than 75%.
At present, most CPU patents in the world are in the status of "pending approval" and "valid", and the total number of CPU patents is 5 1 10000 and 157800 respectively, accounting for 24.3% and 75.0 1% of the total number of CPU patents in the world. The number of CPU patents in the PCT formulation period is 1452, accounting for about 0.69% of the total CPU patents in the world.
(4) Market value of patents: the total value is as high as10 billion US dollars, and there are many patents below 30,000 US dollars.
At present, the total patent value of the global CPU industry is $28.254 billion. Among them, the number of CPU patent applications under $30,000 is the largest, with123,300; Followed by 300,000-300,000 US dollars of CPU patents, with a total of 57,700 patent applications. The number of CPU patent applications above $3 million is the least, which is 1399.
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. Patented technology types in the global CPU industry
(1) Patent type: invention patents account for 69.27%.
In terms of patent types, there are currently 144700 CPU patents in the world as invention patents, accounting for the largest number of CPU patent applications in the world, accounting for 69.27%. The number of utility model CPU patents and design CPU patents is 63,700 and 52 1 piece respectively, accounting for 30.48% and 0.25% of the global CPU patent applications respectively.
(2) Technical composition: the first technology accounts for more than 20%.
From the technical composition, at present, "Take G06F9 program control device as an example, the control unit (program control of external equipment G 01310) [2018.01]" has the largest number of patent applications, accounting for1300. Secondly, "devices, equipment, circuits and systems not included in the single group H04L29 H04L 1/00 to H04L27/00 [5] [2006.0 1]", and the patent application amount is12/KLOC-0.
(3) Technical Focus: Ten Hot Spots
The top ten technical terms of CPU in the world include output terminal, portable, terminal equipment, electronic equipment, radiator, computing system, central processing module, detection system, robot and input terminal. Subdivided, CPU technology buzzwords include sensors, servers, controllers, CPU, memory 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 patents cited: Oracle Bone Inscriptions's patents have been cited more than 1,000 times.
The system and method for managing virtual server applied by Oracle Bone Inscriptions Company (patent number: US20050120160a1) is the most cited CPU patent, exceeding 1000 times. The other ten patents cited are as follows:
3. Patent competition in the global CPU industry
(1) Distribution of technology source countries: China accounts for the highest proportion.
At present, China is the largest source of CPU technology in the world, and the number of CPU patent applications in China accounts for 58.32% of the total number of CPU patent applications in the world. Followed by the United States, the number of CPU patent applications in the United States accounts for 15.99% of the total number of CPU patent applications in the world. Although Japan and South Korea rank third and fourth, they are far behind China, which ranks first.
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.
