HVDC Transmission for Agricultural Irrigation Patent Landscape
HVDC Transmission for Agricultural Irrigation Patent Landscape in 2026
The corpus of 20 patent families covering HVDC transmission for agricultural irrigation is extremely concentrated, with two applicants — Cilag GmbH International and Ethicon Inc — together accounting for the entire top tier. Filing activity peaked in 2022 and has since eased, placing the field in a post-peak phase with limited new entrants visible.
Two applicants dominate an early-stage, highly concentrated field
Cilag GmbH International leads with 13 patent families, followed by Ethicon Inc with 7 patent families. Together these two filers represent the entirety of the top-ranked applicants in scope, indicating an exceptionally narrow competitive field.
The top five filers account for 100% of the hundred largest filers’ combined total, a concentration level that signals a duopoly rather than a broad ecosystem. There is no meaningful second tier of challengers visible in the evidence.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Cilag GmbH International | 13 | |
| 2 | Ethicon Inc | 7 |
The leaders’ positions imply that any new entrant would face a significant prior-art density from these two entities, particularly in power-supply and grid-systems classifications. The absence of collaboration activity further suggests the field has developed in closed, proprietary silos.
Filings from the most recent 18–24 months are subject to publication lag and are likely under-represented; the apparent drop-off in 2023–2026 should not be read as a definitive indication of withdrawal. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity peaked in 2022; power-supply systems dominate the technology mix
The annual filing trend and technology-composition charts together reveal a field that surged in 2019–2022 and has since contracted, while remaining structurally anchored in power-supply and grid-systems patents.
Annual filing trend
Filings were negligible before 2019, rose to a peak of 7 families in 2022, and fell sharply to 1 in both 2023 and 2024. The 2023–2026 period is subject to publication lag, so the near-zero readings for 2025–2026 are not reliable indicators of field exit. The field’s multi-year recent-window growth is negative at –18%, consistent with a post-peak phase.

H02J (power supply and grid systems) is the dominant IPC branch, reflecting the core infrastructure claims. A61B (diagnosis and surgery) appears prominently, which is atypical for an irrigation-focused corpus and may reflect applicant portfolio breadth rather than direct irrigation relevance. Smaller branches including H03F, G16H, H05K, G06F, H03M, and H04L account for the remaining share, none individually exceeding the leading branch.

What the patent structure means for R&D investment decisions
The combination of high concentration, post-peak filings, and an unusual IPC mix warrants careful interpretation before committing R&D resources to this space.
Post-peak field with declining annual volume
The lifecycle stage is classified as Decline: annual filings have eased back from the 2022 peak of 7 families, and the recent-window growth rate stands at –18%. This does not necessarily signal commercial obsolescence, but it does indicate that the burst of activity from 2019–2022 has not been sustained. Engineers should assess whether the core claims have been resolved or whether applicant strategy has simply shifted.
Declining activityDuopoly with no visible second tier
Cilag GmbH International and Ethicon Inc together hold all ranked positions among the top 100 filers, with the top five collectively holding 100% of that group’s combined total. This extreme concentration means that freedom-to-operate assessments must focus tightly on these two entities’ portfolios. New entrants face a high prior-art barrier within the current scope but would also benefit from the absence of a broad, multi-player prior-art landscape.
High concentrationNo co-filing activity detected
The collaboration evidence shows no co-applicant filings within this corpus. The field has developed entirely through independent proprietary filing by individual entities, with no evidence of joint development agreements, university partnerships, or cross-industry consortia. This leaves open the possibility that collaboration-based entry — particularly with agricultural technology institutions — could differentiate a new applicant.
No collaborationEurope and the United States are the primary filing jurisdictions
Europe (EPO) leads with 8 patent records, followed by the United States with 5, WIPO (PCT) with 4, India with 2, and Germany with 1. The presence of India as a jurisdiction is notable given its large agricultural irrigation sector. The relatively thin PCT and Indian coverage could represent a strategic gap for applicants seeking protection in high-irrigation-demand markets.

Cilag GmbH International leads; Ethicon Inc is the sole challenger
The two ranked applicants share overlapping IPC focus areas, particularly in power-supply systems and surgical/diagnostic classifications, suggesting their portfolios may be strategically linked rather than independently positioned.
Cilag GmbH International
Cilag GmbH International holds 13 patent families, the largest position in scope. Its technology emphasis is led by H02J 3 (power supply and grid systems) with 11 filings, followed by A61B 18 (diagnosis and surgery) with 8, and H03F 1 (amplifiers) with 8. Applicant momentum is flagged as a new entrant on a recent basis, suggesting the bulk of activity is recent rather than accumulated over many years.
families: 13Ethicon Inc
Ethicon Inc holds 7 patent families. Its technology focus is split across A61B 18 (diagnosis and surgery) with 8 records, H02J 3 (power supply and grid systems) with 8, and A61B 34 (diagnosis and surgery) with 7, indicating a heavier emphasis on surgical classifications relative to Cilag. No momentum trend data beyond the ranking was available for Ethicon in the evidence.

Under-served IPC branches adjacent to the dominant power-systems core
Several lower-share IPC classes appear in the corpus at modest levels relative to H02J. These represent observations of relative sparsity; technical value and entry feasibility should be evaluated independently before treating them as investment targets.
H04L · Digital information transmission
H04L accounts for only 4 patent records in the corpus — the smallest branch by count among the identified adjacent classes. For HVDC irrigation applications, digital communication overlays (e.g., supervisory control and real-time telemetry for remote irrigation infrastructure) represent a plausible extension of grid-systems patents. The sparse prior art in this branch means a focused applicant with expertise in industrial IoT or SCADA communications could establish early positions with limited crowding.
Search this in Eureka →H03M · Coding & code conversion
H03M (coding and code conversion) appears with 5 patent records and a share of 7% among the adjacent branches. In a power-systems context, coding and modulation techniques are relevant to signal integrity over long HVDC transmission lines, including error-correction for control signals managing irrigation pump stations. Entry into this branch would likely require collaboration between power-electronics engineers and communications specialists, and the thin prior art suggests the combination has not been systematically pursued.

Frequently asked questions
The corpus contains 20 patent families in scope. This is a very small corpus, and conclusions about competitive dynamics should be weighted accordingly.
Cilag GmbH International leads with 13 patent families, followed by Ethicon Inc with 7 patent families. These two entities account for the entirety of the ranked applicant list in the evidence.
Filings peaked at 7 families in 2022 and fell to 1 each in 2023 and 2024. The recent-window growth rate is –18%, indicating a post-peak phase. Filings from 2023 onward are subject to publication lag and may be under-counted.
Europe (EPO) has 8 patent records, the United States has 5, WIPO (PCT) has 4, India has 2, and Germany has 1. Europe is the primary filing office, with India notable given its large irrigation sector.
H02J (power supply and grid systems) is the dominant IPC branch with 20 patent records, followed by A61B (diagnosis and surgery) with 18. The prominence of A61B is atypical for an irrigation-focused topic and may reflect the applicants’ broader portfolio strategies.
No co-applicant filings were detected in the evidence. All activity has been filed independently by individual entities, with no visible joint development agreements or cross-sector partnerships.
