be developed prior to mass market release of a product implementing those technologies. At a higher level of capability,
5G specifies standards for enhanced Machine-Type Communication( eMTC), which provides higher data rates than for NB- IoT. Devices with eMTC functionality are suited to applications involving consumer devices such as wearables and security systems, which may have a need for voice capabilities and / or the ability to exchange more data.
As shown by Figure 2, a significant number of patent applications that mention e-MTC in their description are published each year, though the overall number is lower than for NB-IoT. The patent filing frequency for eMTC follows a very similar pattern as the patent filing frequency for NB-IoT, with a peak in publications again observed in 2021.
At the upper end of capability, 5G technologies include enhanced Mobile Broadband( eMBB) and Ultra-Reliable Low-Latency Communications( URLLC).
eMBB has use cases in high bandwidth consumer applications such as high-definition( HD) and ultra-HD video and extended reality applications. The patent publication data for eMBB is shown in Figure 3 and highlights that the publication peak occurs in 2022.
URLLC is important in mission-critical applications that require high dependability. Thus, URLLC has relevance in multiple applications that require superlative control and synchronization such as autonomous vehicles, electrical distribution, remote surgery and manufacturing. Figure 4 includes the patent publication data for URLLC, which demonstrates a very similar trend to that seen for eMBB.
As is apparent from a comparison of Figures 1 to 4, the overall number of patent filings has been highest for eMBB and URLLC-related applications, potentially
