MSR Instrumentation Patent Snapshot 2026
The patent corpus for MSR instrumentation contains a single family on record, filed by Saltfoss Energy APS through the PCT system in 2025, indicating this is an extremely nascent and open field. No established incumbents or co-filers are present, signalling that the assignee snapshot remains essentially uncontested.
Saltfoss Energy APS holds the sole recorded position in MSR instrumentation
A single patent family constitutes the current corpus, assigned entirely to Saltfoss Energy APS, which therefore accounts for the entirety of activity among the top-ranked filers in this space.
Concentration is absolute at this stage: Saltfoss Energy APS represents 100% of the top five filers’ combined share of the ranked applicants visible in this query, and no second-tier competitors appear in the ranking.
| # | Applicant | Patent families | Share |

Saltfoss Energy APS’s solitary position implies that no major industrial player or national laboratory has yet staked a formal patent position in MSR instrumentation, leaving the field open to first-movers willing to build a portfolio.
Filing data for the most recent 18–24 months is typically under-counted due to publication lag, so additional applications may be pending but not yet visible in this snapshot. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2025 filing marks the start of recorded activity in MSR instrumentation
The annual filing trend and technology composition both reflect an embryonic field with no meaningful historical volume before 2025. The technology mix is confined to nuclear reactor and nuclear power plant classifications.
Annual filing trend
No filings are recorded from 2017 through 2024; one family appears in 2025. The 2025 and 2026 bars should be treated as provisional given publication lag — additional applications may not yet be indexed.

The sole family is classified under both G21C (Nuclear reactors) and G21D (Nuclear power plants), reflecting the dual scope of instrumentation covering reactor design and plant-level operation. No adjacent IPC branches appear, underscoring the narrow technical footprint to date.

A method of operating a molten salt reactor
The present invention relates to a method of operating an MSR, said MSR comprising a reactor core, a fuel loop for molten fuel salt providing a flow path of molten fuel salt into the reactor core through a reactor core inlet and out of the reactor core through a reactor core outlet, said method comprising the steps of: providing at least one location mi on… (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.
Saltfoss Energy APS
Saltfoss Energy APS holds 1 patent family, filed in 2025 via PCT, covering nuclear reactor instrumentation classified under G21C 1, G21C 3, and G21C 17. Applicant momentum data is not available for a prior-period comparison, as this is the company’s first recorded filing. Their technology focus is squarely on reactor-level monitoring and control, with no diversification into adjacent branches yet visible.
families: 1No challenger on record
No second-ranked applicant exists in the current dataset. The challenger position is effectively vacant, representing a structurally open entry point for established nuclear instrumentation firms, national laboratories, or advanced-reactor start-ups that choose to file IP in this space.
families: 0Frequently asked questions
The current dataset contains 1 patent family in scope, filed in 2025 by Saltfoss Energy APS via the PCT system. This figure may under-count recent filings due to publication lag.
Saltfoss Energy APS is the sole identified filer, holding the single patent family on record. No other applicants appear in the ranking at this time.
The single family is filed through WIPO PCT, preserving national-phase entry options across member states. No granted national or regional rights are yet recorded in the evidence.
The existing family is classified under G21C (Nuclear reactors) and G21D (Nuclear power plants). Sub-classes G21C 1, G21C 3, and G21C 17 appear in the applicant technology profile, reflecting reactor design and monitoring scope.
Based on current evidence, the space is essentially open. One family from one applicant constitutes the entire corpus, meaning there is minimal prior-art density and no established incumbent portfolio to design around.
Citation data is not available in the current evidence set — no top-cited patents are recorded for this topic. This is consistent with a nascent field where the single existing family has had little time to accumulate forward citations.

Disclaimer. This page is generated from PatSnap Eureka data drawn from a limited snapshot of global patent and scientific-literature records, and is provided for general information and reference only.
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.
