SMR Simulation & Modeling Patent Snapshot 2026
The patent corpus for SMR simulation and modeling is nascent, with only 3 patent families on record, all appearing in 2025. Activity is split evenly across one South Korean company and two Chinese universities, with China accounting for the majority of filings by jurisdiction.
Three applicants share a nascent, highly concentrated field
The SMR simulation and modeling patent evidence snapshot contains just 3 patent families in scope, distributed equally among JC One Korea Co., Ltd., Changchun University, and Harbin Engineering University, each holding 1 patent family.
Concentration is absolute: the top five filers account for 100% of the combined output of the ranked applicants visible in this query, reflecting a field that has not yet attracted broad industrial participation.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | JC One Korea Co., Ltd. | 1 | |
| 2 | Changchun University | 1 | |
| 3 | Harbin Engineering University | 1 |
The presence of two Chinese academic institutions alongside a South Korean commercial entity suggests that early activity is being driven by university research rather than large industrial players, leaving significant room for established nuclear and simulation vendors to enter.
All three families appeared in 2025; publication lag means any additional filings from late 2024 onward may not yet be fully indexed, so the corpus should be treated as a floor rather than a ceiling. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
All activity concentrated in 2025; digital computing and AI dominate the technology mix
The filing trend and technology composition charts together reveal a field that emerged abruptly in a single year, anchored in digital data-processing and AI methodologies rather than purely nuclear-engineering classifications.
Annual filing trend
Zero filings appear in every year from 2017 through 2024; all 3 patent families are recorded in 2025. Because publication lag typically affects the most recent 18–24 months, it is too early to characterize whether 2025 represents a genuine inflection point or the leading edge of a larger cohort still in examination.

G06F (electric digital data processing) and G06N (computing based on AI models) each appear in 2 of the 3 families, indicating that simulation work in this space leans heavily on AI and numerical methods. G21C (nuclear reactors) and G21D (nuclear power plants) each appear once, confirming a nuclear application context but suggesting the computational methods are the primary claimed novelty.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
JC One Korea Co., Ltd.
JC One Korea Co., Ltd. holds 1 patent family focused on nuclear reactor (G21C) and nuclear power plant (G21D) classifications, indicating an application-layer emphasis on actual SMR plant operation rather than purely computational methods. Applicant momentum data is not available for this filer given the nascent filing history.
families: 1Harbin Engineering University
Harbin Engineering University holds 1 patent family concentrated in G06F digital data processing sub-classes, including G06F 113, G06F 119, and G06F 18, pointing to a numerical simulation and data-classification methodology. Changchun University holds an equal position with similar G06F coverage. Both institutions filed in 2025 with no prior-period baseline, so trajectory cannot be assessed.
families: 1Frequently asked questions
The corpus contains 3 patent families in scope, all recorded with a 2025 filing year. No families appear in any year from 2017 through 2024 within this query scope.
Three applicants each hold 1 patent family: JC One Korea Co., Ltd. (South Korea), Changchun University (China), and Harbin Engineering University (China). No single entity holds a plurality position.
China leads with 2 filing jurisdictions, followed by South Korea with 1. No filings are currently visible in the United States, European Patent Office, United Kingdom, or Japan.
G06F (electric digital data processing) and G06N (computing based on AI models) each appear in 2 of the 3 families. G21C (nuclear reactors) and G21D (nuclear power plants) each appear in 1 family, confirming a nuclear application context with computational methods as the primary novelty.
The field is nascent. All known filings appeared in 2025, there is no prior-year filing history in this corpus, and the lifecycle stage cannot be formally characterized. The small corpus and recency of filings suggest that the technology is at or near the very beginning of its patent lifecycle.
Thermal-hydraulic and safety-system simulation, and real-time digital-twin integration for SMR operational monitoring, are notable observations of sparsity. Neither branch is represented in the current 3-family corpus, and both have plausible technical and commercial relevance given active SMR development programs globally.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
