Landscape Analysis of Declared 5G Patent Families (as of May 17, 2020)
5G is the fifth-generation of mobile technologies, following the previous generations (4G, 3G and2G). 5G is set to offer faster speeds and more reliable connections with lower latency on
smartphones and other devices than ever before. A range of applications such as smart homes
and buildings, smart factories, remote healthcare, and self-driving vehicles will be supported by
the emergence of 5G.
We, NGB Corporation, have conducted a landscape analysis of the patent families having at least
one patent application or patent that has been declared by a patent holder to the standardization
organizations like ETSI (European Telecommunications Standard Institute) as standard essential
patents (SEPs) to 5G (herein we call as “declared 5G patent families”). The main purposes of thisanalysis include (1) to figure out that the number of declared 5G patent families of each patent
holder is still increasing, and (2) to figure out the current situation of the number of 5G declaredpatent families that were also declared to 4G, 3G or 2G (herein we call as “patent families declaredboth to 5G and 4G/3G/2G”), and the number of 5G declared patent families that have not been
declared to 4G, 3G or 2G (i.e., declared 5G patent families where all of Technical
Specification(s)/Technical Report(s) (TS/TR(s)) only relate to 5G without any combination with 4G,
3G or 2G, herein we call as “patent families only declared to 5G”), of each patent holder. The
information of the declared patent families is still useful to capture the overall trend of 5G
standardization activities. The results are reported as below.
We collected the declared 5G patent family data to be analyzed, which was available as of May17, 2020 from the IPlytics Platform in view of TS/TR(s) related to 5G. More specifically, we
collected the declared 5G patent family data using the IPlytics Platform by selecting “5G”, “5G/4G”,“5G/4G/3G”, or “5G/4G/3G/2G” as Technology Generation, and also determined whether thedeclared patent families has another generation like “4G”, “4G/3G”, “4G/3G/2G”, “3G”, “3G/2G”,“2G”, to have a data set of the declared 5G patent families. With respect to the “patent families
only declared to 5G”, we extracted the patent families wherein all of the TS/TR(s) relate to “5G”
only, without “5G/4G”, “5G/4G/3G”, “5G/4G/3G/2G”, “4G”, “4G/3G”, “4G/3G/2G”, “3G”, “3G/2G”,
or “2G”.
Figure 1 shows a trend of cumulative number of each patent family over months. The blue areashows a cumulative number of the 5G declared patent families in terms of declaration month.
The red line shows a cumulative number of “5G granted patent families” that have at least one

1NGB IP Research Institutegranted patent as of May 17, 2020. Some of the patent application(s) in the “declared 5G patentfamilies” as of the declaration month become granted patent(s) over times. In each dot in the redline, we determined whether the declared 5G patent families in each declaration month have atleast one granted patent as of May 17, 2020, rather than as of each declaration month.
The substantial rise in the declared 5G patent families started from around December, 2017, andthe declared 5G patent families keep continuous growth since then.

Table 1 shows the ranking of the top 15 companies in terms of the number of the “declared 5Gpatent families” (see column A) and the proportion of each company’s patent families based on
the total number of the declared 5G patent families (see column B and Figure 2). We integrated
Nokia’s data with Alcatel-Lucent’s data as Nokia group’s data.
As of May 17, 2020, the total number of the “declared 5G patent families” is 29,586. Huawei(5,947 patent families) is first placed in the ranking and accounts for 20.1% of the total. Othercompanies having more than 2,000 declared 5G patent families are Samsung (3,392 patentfamilies, 11.5%), QUALCOMM (2,755 patent families, 9.3%), ZTE (2,606 patent families, 8.8%),LG (2,588 patent families, 8.7%), and Nokia Group (2,442 patent families, 8.3%).

We
can see that Huawei has nearly a quarter of the total number of the patent families only declared
to 5G. Comparing with Table 1, Table 2 shows that the proportion of Huawei is increased by 4.1
points and the proportion of Samsung is decreased by 3.3 points. This indicates that Samsung
has more patent families declared both to 5G and 4G/3G/2G.
We used the same order of the top 15 companies in Table 1 and Figure 2, when generating Tables
2 to 4 and Figures 3 to 5, respectively.

number of the 5G granted patent families (see column F and Figure 4). While Huawei (2,796
granted patent families) is still first placed in the ranking, Samsung (2,134 granted patent families)
in second place closes the gap with Huawei compared with the situation in Table 1 (Huawei: 5947
patent families, Samsung: 3,392 patent families). Comparing with Table 1, Table 3 shows that theproportion of Huawei is decreased by 0.4 points and the proportion of Samsung is increased by
3.6 points. ZTE, Catt, Oppo, Intel, Vivo, and Lenovo have a less proportion of the 5G granted
patent families when compared with the situation in Table 1. It is likely that these companies havemore patent families having pending application under examination.

number of granted patent families only declared to 5G (see column H and Figure 5, i.e.,
G/Total(6,863)[%]). The “granted patent families only declared to 5G” means the “patent families
only declared to 5G” having at least one granted patent as of May 17, 2020. We can see thatHuawei has more than 30% of the total number of the granted patent families only declared to5G. Comparing with Table 1, Table 4 shows that the proportion of Huawei is increased by 11.4
points, which is the largest increase among all companies.

7NGB IP Research InstituteAs shown in above, we can see a remarkable increase in the number of declared 5G patentfamilies, and would expect that more and more patent families show up in the record if we takedata in the future so that it may possibly change the current trend significantly. We would update
this report especially when we see such a significant trend change.
