To find the key IPR holders for the 5G NR (New Radio) Standard Essential Patents (SEPs) for the US market, patents in the lists of patents declared essential to 3GPP TS 38 Release 15 specification series (http://www.3gpp.org/DynaReport/38-series.htm) appear at the ETSI IPR Online website (https://ipr.etsi.org/) are searched. Total of 4935 5G NR declared SEPs (including 2110 pending & 930 published USPTO patent applications) are searched as of 2Q 2018.
Ericsson is the leader in 5G NR SEPs declaration followed by Samsung Electronics, Sharp, Huawei (including Futurewei Technology), Qualcomm, and LG Electronics. It is interesting to find the IPR leadership in 5G NR SEPs declaration of Sharp and Huawei. It is also interesting to find InterDigital’s small number of 5G NR SEPs declaration and Nokia’s no declarations, which are one of IPR leaders in 3G & 4G SEPs.
The top 6 most declared specifications for the 5G NR SEPs are TS 38.213 (Physical layer procedures for control), TS 38.214 (Physical layer procedures for data), TS 38.211 (Physical channels and modulation), TS 38.331 (Radio Resource Control (RRC); Protocol specification), TS 38.212 (Multiplexing and channel coding), and TS 38.321 (Medium Access Control (MAC) protocol specification).
