Methanol Marine Propulsion Patent Snapshot 2026
The patent corpus for methanol marine propulsion is currently represented by a single family filed in 2024, with Air Products & Chemicals holding the only identified position via a PCT application. The field is at an embryonic stage, leaving broad technology space unoccupied and the competitive structure entirely open.
Air Products & Chemicals holds the sole identified position in a nascent field
The current corpus contains 1 patent family in scope, filed by Air Products & Chemicals — making it the top-ranked and only applicant in the dataset. With a top-five share of 100% of the ranked applicants visible in this query’ combined total, concentration is absolute by construction at this corpus size.
There is no tier structure to describe: a single applicant occupies the entire identified evidence snapshot. This is a meaningful signal that systematic patent prosecution in methanol marine propulsion has not yet begun at scale among the broader shipping, fuel-supply, or engine-control industries.

Air Products & Chemicals’ position — rooted in gas separation, inorganic chemistry, and fuel-supply technology — suggests the filing originates from the fuel-production and supply-chain side of the value chain rather than from a shipbuilder or engine OEM. Adjacent sectors have not yet staked visible patent claims in this specific intersection.
The sole family was filed in 2024 and published via PCT; given standard 18-month publication lag, any filings from late 2024 onward may not yet be visible in the corpus. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2024 filing marks the visible start of patent activity in this intersection
The annual filing trend and technology composition together characterize methanol marine propulsion as a field with no recorded activity from 2017 through 2023, followed by one filing in 2024 across six IPC branches. The technology mix reflects the multi-disciplinary nature of the topic.
Annual filing trend
No filings appear from 2017 to 2023; one family was recorded in 2024. Zero counts in 2025 and 2026 are expected given publication lag and should not be read as absence of current activity.

The single family maps across six IPC branches — separation processes (B01D), marine propulsion and steering (B63H), non-metallic elements and inorganic compounds (C01B), engine control (F02D), fuel supply and carburettors (F02M), and gas liquefaction and separation (F25J) — illustrating the cross-disciplinary scope of a methanol marine fuel-system invention.

Apparatus and method for nitrogen generation for m…
An apparatus for nitrogen generation for methanol powered maritime vehicles can include a compression system for compressing air and feeding compressed air to a separation unit for separation of nitrogen and oxygen from the compressed air. The nitrogen can be output from the separation unit for storage at an elevated pre-selected pressure suitable for… (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.
Air Products & Chemicals
Air Products & Chemicals holds 1 patent family in scope, filed in 2024 via PCT — marking it as a new entrant (trend: new entrant) in this specific intersection. Its technology emphasis spans separation processes (B01D), marine propulsion and steering (B63H), and non-metallic elements and inorganic compounds (C01B), pointing to a fuel-production and supply-chain orientation rather than a propulsion-hardware focus.
patent families: 1No second applicant identified
No challenger-tier applicant is present in the current corpus. The second player card cannot be populated from available evidence. Researchers should monitor new PCT publications and national filings from engine OEMs, shipbuilders, and alternative-fuel technology companies as the field develops.
patent families: —Frequently asked questions
The current corpus contains 1 patent family in scope. This reflects the very early stage of formal patent prosecution in this specific intersection of methanol fuel technology and marine propulsion.
Air Products & Chemicals is the only identified applicant, holding 1 patent family filed in 2024 via PCT. No other applicant appears in the ranking dataset.
The sole family was filed through WIPO (PCT). National-phase elections — which would confirm target commercial jurisdictions — are not yet visible in the corpus.
The single family is classified across six branches: B01D (separation processes), B63H (marine propulsion and steering), C01B (non-metallic elements and inorganic compounds), F02D (engine control), F02M (fuel supply and carburettors), and F25J (gas liquefaction and separation).
It is consistent with the evidence available, but the corpus is narrow in scope. Broader searches across related IPC classes or alternative fuel marine technology may reveal prior activity. The zero counts from 2025 and 2026 reflect publication lag and do not indicate no current filing activity.
Based on co-classified branches on the existing family, engine control (F02D) and fuel supply hardware (F02M) for marine methanol duty cycles appear sparsely prosecuted relative to their technical complexity. These represent adjacent branches worth monitoring, though the sparse corpus means any white-space reading should be validated with a broader search before informing an follow-up research decisions.

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.
