Microreactor Passive Safety Patent Snapshot 2026
The patent corpus for microreactor passive safety is extremely small, comprising 2 patent families entirely held by a single applicant filing exclusively in the United States. Activity peaked in 2020 and has since eased, leaving this niche technically open but with very limited established prior art.
Single-applicant dominance in an embryonic niche
Global Energy Research Associates LLC holds all 2 patent families in scope, ranking first and only among identifiable filers — an absolute monopoly within the current corpus.
The top five filers account for 100% of the ranked applicants visible in this query’ combined total, reflecting a corpus so small that no meaningful tier structure has formed. There is no second-tier challenger visible in the data.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Global Energy Research Associates LLC | 2 |
The sole leader’s position implies that any new entrant would face minimal blocking density, but also that the space lacks the broad cross-institutional validation that typically signals commercial momentum.
The corpus covers filings visible in available records; the most recent 18–24 months may be under-counted due to publication lag, so the absence of post-2020 activity should be interpreted cautiously. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single filing cohort in 2020 defines the entire activity profile
Both the annual trend and the technology composition are shaped entirely by a single burst of activity in 2020. The IPC class mix reflects a dual nuclear-plus-gas-turbine framing for passive safety.
Annual filing trend
All 2 patent families were filed in 2020; no filings appear in any other year of the visible window. Years after 2022 should be treated as potentially under-counted due to publication lag, but the gap from 2021 onward is notable regardless.

The IPC branches F02C (gas-turbine plants), G21C (nuclear reactors), and G21D (nuclear power plants) each carry 2 records, indicating that the existing filings span all three classes simultaneously — consistent with a hybrid microreactor concept integrating passive nuclear and gas-turbine safety.

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.
Global Energy Research Associates LLC
Holds all 2 patent families in scope, filed in 2020 and covering F02C gas-turbine plants, G21C nuclear reactors, and G21D nuclear power plants simultaneously. No momentum data is available for subsequent periods, consistent with the single-cohort filing pattern. The technology emphasis on hybrid gas-turbine/nuclear passive safety is distinctive within the corpus.
families: 2Adams Mark Lloyd
Listed as a named applicant in the route data and shares the same IPC focus — F02C, G21C, and G21D — with 2 records each. The overlap with Global Energy Research Associates LLC suggests an individual inventor and associated LLC filing structure rather than two independent competitors. No challenger from outside this entity pair is visible in the evidence.
families: 2Frequently asked questions
The current corpus contains 2 patent families in scope, all filed in the United States and all attributed to Global Energy Research Associates LLC.
Global Energy Research Associates LLC is the sole ranked applicant, holding all 2 patent families. Adams Mark Lloyd appears as a named applicant in the same filings, suggesting an individual inventor and associated LLC structure.
Both patent records are filed exclusively in the United States. No international or regional patent-office filings appear in the available data.
The corpus spans three IPC classes: F02C (gas-turbine plants), G21C (nuclear reactors), and G21D (nuclear power plants), each with 2 records. The overlap suggests a hybrid gas-turbine/nuclear passive safety concept.
The evidence places the field in a decline stage, with annual filings easing back from a 2020 peak and no subsequent activity in the visible record. Publication lag means very recent filings may not yet appear, but the post-2020 gap is notable.
The thin corpus and single-jurisdiction footprint mean blocking density is extremely low. However, the absence of institutional co-filers and the post-peak trajectory suggest the space has not yet attracted broad R&D investment. New entrants would encounter minimal prior-art conflict but would need to build IP foundations substantially from scratch.

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.
