- Filing activity peaked in 2019 at 36 records and has fallen back toward single digits since, with the 2022 midpoint at just 3 — a technology that surged then cooled rather than one still climbing.
- Hydraulic conversion, not connectivity, dominates the claim space F03B hydraulic machines account for 47 of 98 records versus 16 for H04B transmission, meaning most filings still protect energy capture, not the telemetry layer.
- The most-cited record in the set is a 166-citation outlier US20120032876A1 sits far above the next tier (39 citations), signalling one foundational filing rather than a broad, contested core.

Overview
What this landscape covers
This dataset tracks patent families at the intersection of wave energy conversion and the wireless connectivity and remote condition monitoring systems used to operate them offshore — telemetry links, underwater connectors and data transmission architectures rather than the generator or hydraulic mechanisms alone. The search combines wave energy converter and ocean wave energy terms with remote condition monitoring, offshore telemetry and wireless data transmission, capturing filings where the two domains are claimed together.
Coverage runs from 2015 through the 2026-07-31 cut-off, across 98 published records and 98 tracked families. Because publication lags filing by roughly 18 months, the last one or two years in any trend chart will read lower than the true filing rate once those applications publish.

The data
Filing trend and technology mix
Two views of the same 98-family dataset: how filing activity has moved year over year, and which IPC subclasses carry the claims.
Filings rose to a 2019 peak, then flattened
Filings climbed from 4 in 2017 to a peak of 36 in 2019, then dropped sharply — the 2022 midpoint sits at just 3 filings, and the trend has stayed flat-to-declining through the most recent, still-partial year. This pattern is more consistent with a burst of early-stage speculative filing around 2018-2019 than with a technology still building momentum.
Hydraulic and hull claims outweigh connectivity claims
F03B (hydraulic machines & engines) leads with 47 records, followed by B63B (ships & marine vessels) at 29 and B63G (naval vessels) at 18. H04B (transmission) accounts for only 16, and G06F (digital data processing) trails at 7 — the connectivity and data-processing layers this search targets are present but consistently outnumbered by the core energy-capture hardware they connect to.
Shares are the percentage of the 98 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

The records shaping this space
Representative filing
Ocean wave energy converter and method of mooring thereof
AMES, P. FOERD
An apparatus for converting the kinetic energy of ocean waves into electricity is disclosed. The apparatus includes a main body member. A generator is located within the main body member. The generator includes an axle having a positive direction and a negative direction. An inner rotor is driven by the axle, wherein the inner rotor is driven only in the negative direction of the axle. An outer rotor surrounds the inner rotor and is also being driven by the axle, wherein the outer rotor is driven only in the positive direction of the driveshaft. A stationary ring is located between the inner rotor and the outer rotor, and a drive rod with an attached buoy is configured to move freely.Filed by AMES, P. FOERD, published 2013-03-21 as US20130069370A1.

What the numbers mean for a filing decision
Four read-throughs of the same corpus, aimed at where claim density and citation weight actually sit.
Filing momentum
36 → ~1
peak (2019) vs latest year
A 2019 surge that did not sustain
Filings hit 36 in 2019 before falling toward single digits, with the 2022 midpoint at only 3. That shape points to a wave of speculative or grant-funded filings around one commercialisation push rather than a steadily maturing field.
Read the partial final year as a floor, not a trend line.
Claim concentration
47 of 98
records tagged F03B
Energy capture still dominates the claim set
Nearly half the dataset sits in F03B hydraulic machines, while H04B transmission — the wireless layer this search is built around — holds only 16. Connectivity claims are being written as add-ons to hydraulic or hull patents more often than as standalone telemetry inventions.
Standalone connectivity claims remain the minority position.
Citation weight
166 citations
top record, US20120032876A1
One outlier, not a contested core
The leading record is cited more than four times as often as the second-placed filing (39 citations). A single foundational patent, rather than a densely cross-cited cluster, anchors the influence structure of this corpus.
Underwater connector filings form the next citation tier.
Filing geography
UK 31, US 21
top receiving offices
UK and US carry most of the filing volume
United Kingdom (31) and United States (21) receive more than half the tracked filings, with WIPO PCT (11), Australia (9), New Zealand (7) and EPO (5) trailing well behind — filing strategy here is concentrated in two national offices rather than spread through PCT routes.
A UK-heavy split suggests test-site proximity is driving venue choice.

Players
Who is filing, and where the field is open
Co-assignee activity is thin — only 4 pairs across the whole dataset — and recent-year momentum has gone flat across every named assignee tracked, including those with historical filing weight.
Filing pattern
4 co-assignee pairs
across 98 families
Mostly solo filers, with a few tight pairings
Co-filing is rare in this corpus. The strongest pairing, Ciamulski Tomasz and Bokenfohr Mark, appears three times; the next tier, Roberts Allan and Lu Weixing, twice. Most assignees file alone rather than through joint ventures or shared R&D agreements.
Sparse co-filing makes freedom-to-operate analysis assignee-by-assignee.
Recent momentum
0 in latest year
across every tracked assignee
No assignee shows current-year activity
Every assignee in the recent-momentum tracking, including WISUB and Ciamulski Tomasz, shows zero filings in the latest year, with one recording a -100% year-on-year drop. This is consistent with the broader flat-to-declining trend rather than a single company's retreat.
Momentum data should be read alongside the 18-month publication lag.
Underwater connectors
39 + 24 citations
two related connector filings
Underwater connector claims form a distinct sub-cluster
US20130321223A1 and WO2012113757A1, both titled around underwater connector arrangements, sit as the second-highest citation tier after the leading record. That pairing signals a recognisable sub-technology within the wider wireless-and-IoT search, worth tracking separately from generic telemetry claims.
Connector hardware claims may be easier to design around than protocol claims.

Where to take this analysis
The trend and citation data point to specific next steps for anyone deciding whether — and where — to file.
Map the connectivity sub-cluster in detail
H04B transmission and G06F data-processing filings are a minority of this dataset but are the parts most directly relevant to wireless and IoT claims; a closer read of just those subclasses will separate genuine telemetry inventions from add-on claims bolted onto hydraulic patents.
Explore the IPC breakdown in EurekaWatch the underwater connector sub-cluster
Two related connector filings sit in the second citation tier behind the corpus leader, suggesting a recognisable technical niche with room to differentiate rather than compete head-on.
Trace connector-family citations in EurekaTreat the 2019 peak as a historical marker, not a baseline
With the 2022 midpoint at only 3 filings and the latest tracked year showing zero activity across named assignees, any forecast should be built on the flat post-2019 trend rather than the peak year.

FAQ
Common questions about this landscape
The tracked dataset contains 98 published records and 98 patent families covering filings from 2015 through mid-2026. This counts filings where wave energy conversion terms are claimed together with remote condition monitoring, offshore telemetry or wireless data transmission language, not the broader wave energy field as a whole. Because publication lags filing by around 18 months, the true current filing rate is likely somewhat higher than the most recent partial year shows.
Filing activity peaked in 2019 at 36 records and has since fallen sharply, with the 2022 midpoint at only 3 filings and the most recent tracked year showing no activity across the named assignees in the momentum data. That pattern reads as a filing burst followed by a cooling period rather than sustained growth. Anyone using this data to justify a filing decision should weight the post-2019 trend more heavily than the peak year.
Hydraulic machinery (IPC class F03B) carries the most claims by a wide margin, at 47 of 98 records, followed by ships and marine vessel structures (B63B) at 29 and naval vessel classes (B63G) at 18. Wireless transmission (H04B) accounts for only 16 records and digital data processing (G06F) just 7, meaning the connectivity and IoT elements this search targets are usually claimed as features within a broader energy-capture or hull patent rather than as standalone inventions.
US20130069370A1, filed by Ames, P. Foerd and published 2013-03-21, discloses an ocean wave energy converter with a main body member housing a dual-rotor generator — an inner rotor driven only in the negative axle direction and an outer rotor driven only in the positive direction, separated by a stationary ring — plus a mooring method using a buoy-attached drive rod. It is a mechanical energy-capture and mooring patent, not a connectivity or telemetry patent, so it constrains generator and mooring architecture rather than any wireless data link built on top of it.
The clearest gaps sit in the connectivity layer itself: standalone claims around mesh telemetry linking multiple converters in an array, subsea wireless power-and-data coupling, buoy-mounted edge processing for predictive maintenance, and acoustic or optical underwater links all show some activity but far less claim density than the hydraulic and hull classes. A first claim in one of these areas would do best to tie a specific data-transport mechanism to a specific offshore failure mode or maintenance trigger, rather than claiming wireless monitoring generically.
