According to the latest reports from Zhizhi, we can see that among the companies and institutions with a global number of TOP20 patents in the Internet, there are six in China, among which ZTE is in the forefront, but from the perspective of patent quality, it is not optimistic. .
In 2016, consulting firm LexInnova released a survey report related to IoT patents. Qualcomm ranked first in the Internet of Things with a patented technology of up to 724. In particular, it is worth mentioning that the number of patents in the Internet of Things is growing rapidly in 2016. Several companies, the first is Qualcomm, which has grown 157 patents. The total number of patents of the Chinese Legion represented by ZTE and Huawei is 879, accounting for more than 20% of the total number of Top20 patents.
Market value
As for the market potential of the Internet of Things, let's see what everyone says.
Cisco's forecast is that the global Internet of Things market will reach $14.4 trillion in 2022. The specific distribution is: $3.7 trillion from improving user experience, $3 trillion from shortening time to market, $2.7 trillion from supply chain links and logistics, $2.5 trillion from cuts in expenses, and $2.5 trillion from improving employee productivity .
Juniper Research predicts that global connected devices will reach 38.5 billion units by 2020, an increase of 285% from the 13.4 billion units in 2015.
Patent segmentation
IoT technology is classified from the perspective of patents, mainly in the categories of network, computing, and basic equipment (the fourth block in the above table can be understood as other). Among them, the network-wired-communication protocol sub-category achieved the highest number of patent applications, reaching 5009; the second place was the network-wireless-specific adaptation service/equipment classification, and the number of patent applications reached 3,747. The third place is the calculation-encryption-data security classification, with 3,198 patent applications.
Generally speaking, the patent reserves in network communication are huge, and there are many patents in information processing and retrieval, while the patents on optical acoustics have huge gaps.
However, in addition to the number of patent applications, the quality of patents under each category is also examined. The industry measures the quality of the parameters as patent strength.
In fact, there are several evaluation indicators for patent quality. In this paper, LexInnova cites the patent strength analysis method published by Mark A. Lemley, Kimberly A. Moore, John R. Allison, and R. Derek Trunkey. The high-strength patents reorganized the classifications in the table below.
Under the high-intensity patent classification, the most frequently applied application is information retrieval technology, with a total of 309 patent applications, but this figure only accounts for 9.72% of the total number of patent applications in the field. Acoustic-related high-strength patents are still the least, with only three. The highest proportion of high-intensity patents in their respective fields is the direction of character recognition, accounting for 11.76%; the lowest proportion is e-commerce, with a ratio of only 0.65%.
LexInnova counts the year-to-year changes in the number of patent publications in the Internet of Things from 1997 to 2015. Basically from 1997 to 2002, the first growth period of the Internet of Things patent from scratch. The number from 2002 to 2010 showed a steady accumulation after a small decline, and the overall number was below 1000. It was not until 2010 that there was an explosive growth. In 2015, the number of calendar years was the highest, reaching 6,810. (Note that this patent quantity trend does not include forecasts for 2016.)
