Ship Propulsion Power/Thermal Interface Patent Snapshot
The patent corpus for ship propulsion power and thermal interface is extremely nascent, comprising just 1 patent family, with activity concentrated almost entirely in a single US-based applicant. The field shows no sustained annual filing pattern, signalling that defensible IP positions are wide open for entrants willing to invest.
Raider Outboards leads a near-empty field
Raider Outboards Inc holds the top-ranked position with 2 patent records, followed by Brunswick Corp with 1 patent record — together accounting for all activity among the largest filers in this space.
Concentration is absolute: the top five filers collectively represent 100% of the ranked applicants visible in this query’ combined total, reflecting a corpus so small that no meaningful tier gap exists beyond the lead applicant.
| # | Applicant | Patent records | Share |
|---|---|---|---|
| 1 | RAIDER OUTBOARDS INC | 2 | |
| 2 | Brunswick Corporation | 1 |
Raider Outboards’ position, while numerically visible, rests on a very thin base, meaning any new entrant filing even a handful of well-scoped patents could immediately become a co-leader in this technology area.
Filing counts for the most recent 18–24 months are subject to standard publication lag and likely under-represent actual activity; the true current state may differ from what the trend chart shows. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single filing event in 2022 defines the entire activity window
The annual filing trend and technology composition together reveal a field that has seen minimal sustained output; only one filing event is visible in 2022, with no recorded activity in surrounding years.
Annual filing trend
A single filing appears in 2022 against a baseline of zero across all other years from 2017 to 2026. Given publication lag, any activity from 2024 onward is likely under-counted and should not be read as confirmed absence.

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.
Raider Outboards Inc
Raider Outboards Inc leads with 2 patent records, concentrated in B63H21 (marine propulsion systems), B63H5 (propeller drives), and H02K7 (mechanical integration of electric motors). The named inventors — Gil, Loukusa, O’Brien, Omohundro, Rebele, and Schroeder — all share the same IPC focus profile, indicating a tightly coordinated team working a single technical concept. No momentum trend is available for this applicant from the evidence.
patent records: 2Brunswick Corp
Brunswick Corp holds 1 patent record, exclusively in B63H21 (marine propulsion and steering). The applicant momentum evidence flags Brunswick Corp as a new entrant in the recent period, suggesting the company has begun staking a position in this space from a previously zero base. Given Brunswick’s broader marine product portfolio, this could signal the start of a more systematic IP build-out.
patent records: 1Frequently asked questions
The corpus stands at 1 patent family in scope. This is an extremely small dataset, meaning any structural observations should be interpreted as indicative rather than statistically robust.
Raider Outboards Inc is the top-ranked applicant with 2 patent records, followed by Brunswick Corp with 1 patent record. These two entities account for all recorded activity among the largest filers.
Marine propulsion and steering (B63H) is the visible class with 4 patent records. Electric motors and generators (H02K) follows with 2 records, and electric vehicle propulsion (B60L) has 1 record.
The United States leads with 3 patent records, and China has 1 patent record. No other jurisdictions appear in the evidence, leaving major maritime markets in Europe, Japan, and South Korea currently uncontested at the patent level.
Annual filings show zero activity across most years from 2017 to 2026, with a single filing event recorded in 2022. Filing counts for the most recent 18–24 months may be under-counted due to publication lag.
Yes, the applicant momentum evidence flags Brunswick Corp as a new entrant in the recent period, recording 1 patent record from a previously zero base. This may signal the beginning of a broader IP strategy in marine electric propulsion for the company.

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.
