The leader’s depth in F03B hydraulic machines and engines — reinforced by secondary positions in electric motors and positive-displacement hydraulics — implies that point-absorber and hydraulic power-take-off architectures are the most heavily defended technical routes. Entrants seeking differentiation may need to address less-contested sub-routes.
Filing counts for 2024 and 2025 are incomplete due to standard patent publication delays; apparent volume reductions in those years should not be read as a real contraction of activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity peaked in 2017 and has since plateaued; hydraulic machines dominate the technology mix
The annual filing trend reveals a field that surged to a 2017 peak and has since settled at a lower but sustained plateau. Technology composition is heavily anchored in hydraulic machines and engines, with marine vessel structures, waterway engineering, and electric generators forming a secondary ring.
Annual filing trend
Annual patent records peaked at 325 in 2017 and have oscillated since, with a secondary rise to 322 in 2022 before settling in the 200–210 range through 2023–2024. The 2025 and 2026 counts are materially under-counted due to publication lag and should not be interpreted as real declines.

What the competitive structure means for R&D investment decisions
The combination of a mature lifecycle, a concentrated leader, a geographically US-led filing base, and measurable co-filing activity points to a field where incremental differentiation in adjacent technology routes is more accessible than head-on competition in the core hydraulic domain.
Field has reached a plateau after its 2017 peak
Annual filings have eased from the 2017 peak, and the lifecycle is assessed as mature. The multi-year window still shows positive growth of 20% in recent periods, indicating continued commercial interest rather than contraction. New entrants are more likely to find value in differentiated sub-routes than in re-litigating the core hydraulic machine space.
Mature · plateauedTop five hold 36% of the hundred largest filers’ combined records
Ocean Power Technologies holds a structurally distinct lead, with Lone Gull Holdings as the nearest challenger. The remaining top-ten applicants are closely bunched, suggesting the second and third tiers are still contestable. Firms outside the top five retain meaningful room to accumulate position in adjacent technical routes.
Moderate-high concentrationLimited co-filing detected; Novige AB is the primary co-filer on record
The evidence identifies one collaboration pair: Novige AB co-filing with its Chinese entity counterpart, with 2 joint records. Co-filing activity across the broader field appears sparse, suggesting that most participants develop IP independently rather than through formal joint-development arrangements. This may reflect the early-commercial stage of most wave energy ventures.
Low collaboration densityUnited States leads filing coverage; Europe and PCT routes follow
The United States is the lead jurisdiction with 1,087 patent records, followed by Europe (EPO) with 712, WIPO (PCT) with 662, and Australia with 466. The UK, Canada, Japan, India, and China round out the top ten jurisdictions, reflecting a broad but US-anchored protection strategy. Pacific and Atlantic coastal markets dominate, consistent with the resource geography of wave energy.

Ocean Power Technologies leads on volume; Lone Gull Holdings is the fastest-growing challenger
Two applicants stand clearly above the rest in patent record count. Their technology emphasis and recent filing trajectories differ in ways that matter for competitive positioning.
Ocean Power Technologies Inc
Ocean Power Technologies holds 442 patent records — the highest count in the field — with primary focus on F03B 13 (hydraulic machines and engines), secondary strength in H02K 7 (electric motors and generators), and a third position in F03C 1 (positive-displacement hydraulic engines). This breadth across the hydraulic and electrical power-take-off chain reflects a vertically integrated IP strategy. Recent momentum data is not separately available for this applicant in the evidence, but its accumulated depth positions it as the reference firm in point-absorber architectures.
patent records: 442Lone Gull Holdings Ltd
Lone Gull Holdings holds 322 patent records — second overall — with technical focus on F03B 13 (hydraulic machines and engines), B63B 35 (ships and marine vessels), and H02K 7 (electric motors and generators). Recent filing momentum stands at +19% versus the prior period, indicating active portfolio growth. The combination of marine-vessel and electrical-generator coverage alongside the dominant hydraulic route signals a broader system-level IP posture compared to some single-focus challengers.

Under-served branches adjacent to the hydraulic core
Several IPC branches appear in the corpus at notably lower shares relative to the dominant F03B class. Two stand out as technically adjacent and potentially under-served for wave energy converter innovation.
F16H · Gearing & transmissions
F16H (gearing and transmissions) accounts for 126 patent records and holds only a 1% share among the top IPC branches in this corpus — sparse relative to the hydraulic and marine vessel branches. Mechanical transmission solutions for wave energy systems, including variable-ratio and continuously variable gearboxes adapted to irregular ocean motion, represent a plausible technical direction. Firms with mechanical drivetrain expertise from wind or tidal energy could find an entry path by adapting existing transmission IP to wave-specific load profiles.
Search this in Eureka →H02P · Control of motors & generators
H02P (control of motors and generators) appears at 125 patent records, a share comparable to F16H and low relative to the volume of H02K (electric motors and generators) records in the same corpus. Advanced power electronics and real-time control strategies — including model predictive control and adaptive impedance matching — are increasingly important for maximising energy extraction from irregular wave inputs. The sparsity here, combined with growing interest in AI-assisted control (G06N appears at 12 records), suggests an accessible adjacent space for software and control-system specialists.
