SMR HALEU Materials Supply Patent Snapshot 2026
The formal patent record for SMR HALEU / Materials Supply is currently limited to a single family filed in 2025 by one applicant, signalling that IP activity in this space is at a nascent, pre-competitive stage. The United States is the sole jurisdiction of record, and no co-filing or citation network has yet developed around this topic.
A single applicant holds all recorded IP in this nascent field
The corpus stands at 1 patent family, filed in 2025, with Prodigy Clean Energy Ltd as the sole ranked applicant. At this scale, concentration is absolute: the top filer accounts for the entirety of the retrieved portfolio.
There is no tier structure to analyse — one applicant occupies the entire top-100 ranking. This is consistent with a field where IP formalisation has only just begun, and most relevant know-how likely remains in trade secrets, regulatory filings, or pre-patent R&D.

Prodigy Clean Energy Ltd’s early filing establishes a first-mover position on record in this specific intersection of small modular reactor technology and HALEU materials supply. Whether this represents an isolated commercial bet or the leading edge of a broader wave cannot yet be determined from the evidence.
Because the only filing appeared in 2025 and patent applications typically publish 18 months after filing, additional families covering similar subject matter may exist but remain unpublished. The current corpus should be read as a floor, not a ceiling.
Filing activity emerged in 2025 with a technology focus on reactor and plant design
The annual trend chart shows zero activity across 2017–2024, followed by a single filing in 2025. The technology composition chart reflects IPC classes G21C (Nuclear reactors) and G21D (Nuclear power plants) each represented once.
Annual filing trend
No filings were recorded between 2017 and 2024; the sole patent family appeared in 2025. Because publication lag typically spans 18 months, the 2025 bar should be treated as a minimum — filings made in late 2024 or 2025 may not yet be visible. The 2026 bar shows zero, consistent with lag, not absence of activity.

The single family is classified under both G21C (Nuclear reactors) and G21D (Nuclear power plants), indicating that the claim scope spans reactor design and power-plant integration simultaneously. No other IPC branches are represented, leaving adjacent areas such as fuel fabrication, enrichment process chemistry, or materials handling without any recorded IP in this corpus.

A system for manufacturing, installing, operating, and maintaining at least first and second transportable nuclear power plants. The system includes a first deployment site adapted to receive placement of the first transportable nuclear power plant therein and a second deployment site adapted to receive placement of the second transportable nuclear power… (excerpt from the patent abstract)
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.
Prodigy Clean Energy Ltd
Prodigy Clean Energy Ltd holds the only retrieved patent family in this corpus (1 patent family, filed 2025). Their technology emphasis spans G21C (Nuclear reactors) sub-classes covering reactor design and G21D (Nuclear power plants), suggesting a system-level claim strategy rather than a narrow materials-only focus. No momentum comparison is available given no prior-period activity.
families: 1No challenger identified
No second applicant appears in the retrieved corpus. The challenger position is vacant at this stage of the field’s development. Organisations active in HALEU enrichment (such as Centrus Energy) or SMR development more broadly may file in adjacent IPC classes not captured in this specific search.
families: —Frequently asked questions
The retrieved corpus contains 1 patent family, filed in 2025. This figure reflects patents that have been published as of the search date; additional families filed in the past 18 months may not yet be publicly visible due to standard publication lag.
Prodigy Clean Energy Ltd is the sole applicant in the retrieved corpus, holding the only patent family on record in this specific intersection of SMR technology and HALEU materials supply.
The United States is the only jurisdiction represented, with one patent application (US20250385017A1) on record. No counterpart filings in other countries appear in the corpus.
The single family is classified under G21C (Nuclear reactors) and G21D (Nuclear power plants), indicating a system-level scope spanning both reactor design and power-plant integration.
No cited prior art or co-applicant relationships appear in the current corpus. The field is too nascent to have generated an observable citation or collaboration network within this dataset.
Zero filings between 2017 and 2024 in this specific corpus does not confirm freedom to operate. Relevant IP may exist under broader SMR, uranium enrichment, or nuclear fuel IPC classifications not captured in this search. A comprehensive freedom-to-operate analysis should extend to those adjacent classes.

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.
