Solid-State Transformer for Agricultural Irrigation Patent Landscape
The defined intersection of solid-state transformer technology and agricultural irrigation is an exceptionally nascent space, with a single patent family on record filed in 2021 and concentrated in the H02J power-supply class. No established corporate leaders have staked positions, leaving the field almost entirely open for structured R&D entry.
A single-applicant field with no incumbent concentration
The corpus covers 1 patent family in scope, attributed jointly to four individual co-inventors — Shivpal Ramtirth Verma, Makarand Sudhakar Ballal, Rohit Rajkumar Deshmukh, and Sarvesh Ashok Wakode — who together represent the entirety of documented activity in this technology intersection.
The top five filers’ share of the hundred largest filers stands at 100%, which in practice reflects a field so early-stage that a single cooperative filing constitutes the full documented record. There is no discernible tier gap between incumbents and challengers because no second tier exists yet.

The absence of corporate or institutional assignees implies that the technology has not yet attracted organized R&D investment; the field is shaped by individual inventor activity rather than strategic portfolio building.
Filings from the most recent 18–24 months are subject to publication lag and may undercount actual activity; the corpus should be treated as a minimum bound rather than a complete picture. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2021 filing defines the entire trend; technology is tightly focused on H02J
The annual filing trend and technology composition together describe a field that has not yet developed momentum or breadth. Both charts reflect a single data point rather than an evolving pattern.
Annual filing trend
Activity is confined to a single filing in 2021, with zero recorded filings in all other years from 2017 through 2026. The apparent post-2021 absence should be read cautiously given publication lag affecting recent years, but the overall volume signal is unambiguous: sustained filing activity has not yet emerged.

All documented activity falls under H02J (Power supply and grid systems), with no representation in adjacent IPC classes such as power electronics conversion (H02M), agricultural machinery controls (A01), or sensor and control systems. The single-branch concentration is consistent with an early, proof-of-concept stage.

What the structural evidence means for R&D positioning
With one patent family on record and no corporate incumbents, the strategic reads are necessarily constrained. The following cards summarize what the available evidence does and does not support.
Nascent / pre-competitive stage
The lifecycle stage is classified as Decline by annual filing metrics, reflecting that the sole filing peak occurred in 2021 and no subsequent filings have been recorded. In practical terms this signals a pre-competitive field that never reached sustained growth, not a maturing one. Engineers entering now would face minimal prior-art density.
Pre-competitiveNo incumbent blocking positions
The top five filers’ share of the hundred largest filers is 100%, attributable entirely to one cooperative filing by four individual inventors. No corporate entity holds a blocking portfolio. This creates unusual freedom to operate but also signals that the technology’s commercial viability has not yet been validated by organized R&D investment.
Open fieldFour co-inventors; no institutional co-filers on record
The single patent record (AU2021103175A4) lists four individual co-inventors — Shivpal Ramtirth Verma, Makarand Sudhakar Ballal, Rohit Rajkumar Deshmukh, and Sarvesh Ashok Wakode — filing cooperatively. No university, research institute, or corporate co-applicant appears in the collaboration data. The ecosystem of potential partners remains uncharted at this stage.
Individual inventorsAustralia is the sole jurisdiction on record
The only jurisdiction with documented activity is Australia, with one patent record. Major agricultural economies — the United States, India, Brazil, the European Union, and China — show no filings in this intersection. This geographic sparsity means national patent offices in key irrigation markets represent entirely uncontested filing territory.

Four individual co-inventors share the only filing on record
There are no corporate leaders or institutional assignees in this field. The ranked applicants are individual inventors who co-filed the single documented patent, each credited with 1 patent record.
Shivpal Ramtirth Verma
Credited with 1 patent record (AU2021103175A4, filed 2021 in Australia), with technology focus spanning H02J3, H02J7, and H02J9 sub-classes within power supply and grid systems. Applicant momentum data is not available in evidence.
patent records: 1Makarand Sudhakar Ballal
Co-listed on the same single filing with an identical technology focus across H02J3, H02J7, and H02J9. At the current corpus scale, all four co-inventors are functionally co-equal; no differentiated portfolio trajectory can be inferred. Applicant momentum data is not available in evidence.
patent records: 1Under-served IPC branches adjacent to the documented activity
Given that the entire corpus sits within H02J, several technically relevant IPC branches have no recorded filings at this intersection and represent observations of relative sparsity worth monitoring.
H02M · Power conversion electronics
H02M covers AC-DC and DC-DC converters, inverters, and rectifiers — the core power-electronics building blocks of any solid-state transformer implementation. No filings in this sub-class appear in the corpus. For engineers developing hardware architectures for irrigation-load solid-state transformers, H02M is the most technically proximate unoccupied branch, and entry here would directly protect converter topology choices.
Search this in Eureka →A01G · Horticulture and irrigation methods
A01G encompasses irrigation system design, scheduling, and plant-growth controls — the application-side counterpart to the power-supply claims in H02J. No filings linking solid-state transformer technology to A01G irrigation methods appear in evidence. Claims bridging power delivery efficiency to irrigation scheduling or soil-moisture feedback could occupy this gap and differentiate from purely electrical approaches.

Frequently asked questions
The corpus contains 1 patent family in scope, represented by a single Australian patent record (AU2021103175A4) filed in 2021. This reflects either a genuinely nascent application space or the use of search parameters that have not yet captured broader adjacent filings.
The only documented filers are four individual co-inventors: Shivpal Ramtirth Verma, Makarand Sudhakar Ballal, Rohit Rajkumar Deshmukh, and Sarvesh Ashok Wakode. Each is credited with 1 patent record. No corporate or institutional assignees appear in the ranking.
Australia is the only jurisdiction with recorded activity, holding the single patent record in scope. Major agricultural markets including the United States, India, Brazil, China, and the EU show no documented filings at this intersection.
All documented activity falls under H02J (Power supply and grid systems), specifically sub-classes H02J3, H02J7, and H02J9. Adjacent classes such as H02M (power conversion) and A01G (irrigation methods) are unrepresented in the current corpus.
Based on the annual filing trend, activity peaked at a single filing in 2021 and has not recurred through 2026 in the recorded data. The lifecycle stage is classified as Decline. However, given publication lag affecting the most recent 18–24 months and the minimal corpus size, this should not be read as evidence of a formerly active field contracting — it reflects a technology intersection that has not yet developed sustained filing activity.
The evidence identifies no white-space candidates explicitly, given the corpus size. Based on the IPC composition, H02M (power conversion electronics) and A01G (irrigation and horticulture methods) are the most technically proximate unoccupied branches. These are observations of sparsity rather than validated commercial opportunities; feasibility would need to be assessed independently.
