An analysis of 146 patent families spanning network selection, 5G paging, mobility management, multi-SIM devices and emerging satellite connectivity.
The strongest signal in Kailash Kumar Jha’s patent portfolio is not the number of filings. It is how consistently those filings address what happens when a mobile connection becomes difficult to maintain: a network is congested, one SIM needs attention while another is active, a device moves between cells, or its usual operator becomes unavailable.
Across 529 patent publications grouped into 146 inventor-associated families, the three largest areas PLMN selection and network registration, core-network paging and signaling, and cell selection and handover account for 111 families. That is roughly 76% of the analyzed inventions. Rather than spanning every feature of a smartphone, the portfolio stays close to the decisions that determine whether a device can find, retain and recover network service.
The filings are associated with Samsung entities and cover more than a decade of invention activity. Their technical progression also tells a story: foundational multi-SIM and 5G coordination work is followed by inventions addressing disaster roaming, network slicing and terrestrial/non-terrestrial connectivity.

How Many Patents are Alive/Dead in Kailash Kumar Jha Portfolio?
Patent Filing Trend of Kailash Kumar Jha: The Portfolio Expanded Most Sharply in 2022–2023
The portfolio moves from only three application records in 2014 and eight in 2015 to 55 in 2018. Activity then remains substantial through 2021 before rising to 101 records in 2022 and 106 in 2023. Together, those two years account for 207 of the 529 publications approximately 39% of the full dataset when grouped by application year.
This rise is consistent with sustained invention activity around 5G network procedures, multi-SIM coordination and network-service continuity. It should not, however, be interpreted as a count of newly created inventions in each year: the chart counts publication records associated with application years, including corresponding filings from different offices.

Patent Technology Area
The leading areas are network selection/registration (44), paging/signaling (36), and cell selection/handover (31), together accounting for 111 of 146 families.
1. PLMN Selection and Network Registration: Staying Connected When the Preferred Network Cannot Serve the Device
This is the largest category, with 44 families. The applications address how user equipment discovers, chooses and registers with available Public Land Mobile Networks (PLMNs). Several records focus on disaster conditions, roaming eligibility and transitions between ordinary service and alternative-network access.
For example, US12593268B2 concerns PLMN selection under disaster conditions, while US12538219B2 addresses switching from disaster roaming back to normal service. Together, the examples show a recurring concern with two directions of the same problem: finding a usable network when service is disrupted and restoring the preferred connection afterward.
Why it matters: reliable connectivity depends on more than radio coverage. A handset must also navigate network identity, access rules, registration state and exceptional operating conditions. These patents sit at that control-plane layer rather than at a consumer-facing feature.
2. Core-Network Paging and Signaling: Keeping Devices Reachable Without Unnecessary Network Activity
The second-largest category contains 36 families. Paging allows a network to alert a device to incoming activity even when the device is not continuously exchanging user data. In multi-SIM and 5G environments, deciding which network’s page should be handled and how can be difficult.
WO2020209620A1, the most-cited publication in the provided list, describes paging management for multi-SIM user equipment. Another prominent filing, WO2019074347A1, focuses on signaling a network-slice congestion condition, including a reject indication and back-off interval so a device can avoid immediate repeat requests.
Why it matters: the inventions address a practical balance between reachability, signaling load and user experience. Avoiding repeated access attempts or missed paging events can matter as much as maximizing raw radio throughput when several services or network identities compete for device attention.
3. Cell Selection, Handover and Measurement: Maintaining Service as Coverage Changes
Cell selection and handover account for 31 families; a related measurement-and-reselection category contains another 12. The inventions deal with how a device evaluates candidate cells, chooses where to connect and preserves communication while moving or when radio conditions change.
US12732879B2 describes selection of a non-terrestrial network (NTN) cell, and US12739745B2 concerns measurement in an NTN communication system. Other filings address conditional handover, early measurements, service continuity during cell transition and avoiding call drops.
Why it matters: network continuity increasingly involves more than a conventional move between neighboring terrestrial cell towers. The presence of satellite-related examples shows these established mobility problems being considered under new coverage patterns and network conditions. It does not, by itself, establish adoption in any commercial device or network.
4. Multi-SIM and Personal IoT Networks: Coordinating More Than One Connection
Ten families are classified under multi-SIM and radio-resource management, with another eight focused on Personal IoT Network (PIN) management and joining. Earlier filings address simultaneous voice and data, dual-SIM service switching and resource use when two networks need attention. Later PIN inventions cover how nearby devices discover one another, join a personal network and negotiate services.
WO2020209641A1 provides a concrete example of the multi-SIM problem: the device may need to leave one operator network to initiate an active session on another. Personal IoT work, such as IN577596B on PIN discovery and communication, extends the connectivity theme beyond a single handset’s cellular registration.
Why it matters: the portfolio repeatedly treats connectivity as a coordination task. The question is not simply whether a device can connect, but which connection, SIM, service or peer should receive attention at a given moment.
5. Smaller Themes: Power, AI/ML and Antenna Behavior
The remaining areas are limited in size: thermal mitigation and radio-access switching (two families), AI/ML model management and prioritization (two), and adaptive antenna configuration (one). Their small counts do not support labeling AI or antenna hardware as core portfolio strengths.
These examples are still relevant because they introduce another constraint into the same network-management problem: radio decisions must coexist with battery use, device temperature, model execution and hardware configuration. In the present dataset, however, these are supporting threads rather than the main body of work.
The Most-Cited Patents Reveal Earlier Technical Foundations
The following are the ten leading publication records in the supplied forward-citation list.
| Publication Number | Citation Count | Technology Area |
| WO2020209620A1 | 75 | Core Network Paging & Signaling |
| WO2019074347A1 | 55 | Core Network Paging & Signaling |
| WO2020209641A1 | 37 | Core Network Paging & Signaling |
| WO2020045952A1 | 35 | Cell Selection & Handover |
| WO2017135702A1 | 23 | Core Network Paging & Signaling |
| WO2018203713A1 | 19 | Core Network Paging & Signaling |
| WO2020222531A1 | 17 | Core Network Paging & Signaling |
| US20230012328A1 | 16 | Core Network Paging & Signaling |
| WO2021261843A1 | 14 | Cell Selection & Handover |
| US20240147207A1 | 13 | PLMN Selection & Network Registration |
The distribution is revealing. Eight of the ten examples directly concern paging, network traffic management or multiple SIM/network interactions. This mirrors the portfolio’s category breakdown rather than pointing to an unrelated, one-off area of citation activity.
WO2019074347A1 is particularly illustrative: it does not simply aim to increase network capacity. It proposes how a network can communicate congestion to the device and regulate retries using signaling and timing. That is a different kind of wireless invention improving network behavior when capacity is constrained rather than increasing peak link speed.
Worldwide Patent Filing of Kailash Kumar Jha’s Portfolio
India and the United States are the two largest publication jurisdictions in the source table. Europe follows through EPO filings, while national records also appear in Germany, Austria and several smaller jurisdictions. This is evidence of geographic filing coverage—not a count of distinct inventions independently originating in each country.
The source also contains 95 WO publications. These represent international PCT publication records and are not displayed as a country in the supplied geographic chart. Adding them to the 434 country/regional records reconciles the 529-publication total. A WO publication should not be interpreted as a separate grant of enforceable rights in a worldwide jurisdiction.

The family-origin view is even more concentrated than the filing geography. In the inventor-level category sheet, 142 of 146 families are associated with Indian priority records and four with US priority records. This points to the source of the early application filings behind many global publication families, not necessarily to the physical location of all research or to the inventor’s residence.
How This Portfolio Fits the Competitive Wireless Landscape
Network selection, paging, mobility and radio resource management are common engineering concerns across mobile-device makers, chipset suppliers and network equipment providers. What distinguishes the portfolio analyzed here is the unusually consistent grouping of one inventor’s filings around these device–network control procedures.
The data does not include a comparable inventor-by-inventor or company-by-company dataset for Nokia, Ericsson, Huawei, Qualcomm or other participants. Accordingly, it would be misleading to assign relative leadership, claim a stronger portfolio than those competitors or treat citation counts as evidence of standards-essential status. A valid comparison would need a common search scope, deduplicated families, filing-period controls and matched technology categories.
