HVDC Transmission for Industrial Plants Patent Landscape
HVDC Transmission for Industrial Plants Patent Landscape in 2026
The HVDC transmission for industrial plants patent space is small and highly concentrated, with CET GRP SA holding the leading position among a limited field of active filers. Activity has plateaued near its peak, signalling a mature niche where power conversion topology dominates and control, protection, and measurement sub-fields remain comparatively sparse.

The scale of CET GRP SA’s lead suggests it has built a broad positional portfolio in power conversion for HVDC applications; challengers are meaningfully smaller and will need differentiated technical positioning to compete directly.
Filing counts for 2024 and 2025 are subject to publication lag and likely under-represent actual recent activity; conclusions on trend direction should weight earlier years more heavily. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity plateaued; power conversion dominates the technology mix
Annual filing volume has been modest throughout the observed window, with a soft peak around 2020 and 2024 showing the highest recorded counts. The technology mix is heavily weighted toward power conversion circuits, with adjacent branches in grid systems, control, and protection occupying secondary roles.
Annual filing trend
Filing volume has been low and irregular across the observed period, reaching its highest recorded counts in 2020 and 2024. The 2024 and 2025 data points should be treated as provisional given standard publication lag; apparent zeros in 2025–2026 do not indicate a real cessation of activity.
↗ Hover for values · click a bar to ask EurekaTechnology composition
H02M (power conversion) accounts for the largest share of patent records by a wide margin, reflecting the centrality of converter topology in industrial HVDC design. H02J (power supply and grid systems) is a secondary cluster, while G05B (control), G06F (digital data processing), and H02H (protective circuits) each represent smaller but technically meaningful branches.

What the patent structure means for R&D investment
The combination of a mature lifecycle, high concentration, and a narrow technology mix shapes where new entrants can add value and where incumbents are entrenched.
Field has plateaued near peak activity
The lifecycle evidence places this field at maturity, with annual filings plateaued near their peak. This implies that foundational converter topologies are well-covered and incremental improvement patents are the norm. New entrants should target sub-domains with sparse coverage rather than trying to carve out space in heavily filed converter classes.
Lifecycle: MatureTop five filers dominate the competitive map
With the top five filers holding 58% of the hundred largest filers’ combined total, the field is heavily concentrated. CET GRP SA’s 16 patent records versus Ideal Power Inc’s 8 illustrates a clear leader-challenger gap. Organisations outside the top five face a structurally less crowded but also less validated space.
High concentrationNo co-applicant activity detected in this corpus
The collaboration evidence shows no recorded co-applicant relationships within this dataset. This absence may reflect the niche industrial scope or the proprietary nature of HVDC converter IP, where organisations prefer sole ownership. It also leaves open a potential differentiator for consortia or university-industry partnerships willing to publish jointly.
Evidence pendingUnited States is the primary filing jurisdiction
The United States leads all jurisdictions by patent record count, followed by Europe (EPO) and India. Germany, Austria, WIPO (PCT), Canada, and Norway round out the coverage, indicating that filing strategies are primarily anchored in North America and Western Europe. India’s presence, driven partly by academic filers, suggests growing technical interest in the region.

Co-filing pairs, ranked by the number of jointly-filed patent families.
CET GRP SA leads on conversion breadth; General Electric Co focuses on protection and grid
The top two tiers are separated by a meaningful gap in patent record counts. Technology emphasis diverges sharply between the conversion-focused leaders and the grid/protection-focused challenger.
CET GRP SA
CET GRP SA holds 16 patent records, the highest in the ranking. Its affiliate entity Ideal Power Converters (4 patent records) and related filer Ideal Power Inc (8 patent records) are both concentrated in H02M power conversion sub-classes, covering AC/DC, DC/DC, and related converter circuits across H02M7, H02M5, and H02M3. Momentum data does not flag a recent acceleration, consistent with an established portfolio rather than a fast-expanding one.
families: 16General Electric Co
General Electric Co holds 5 patent records and is the only top-ranked applicant with a primary focus outside power conversion: its portfolio centres on H02H (protective circuit arrangements) and H02J (power supply and grid systems), making it technically complementary rather than directly competitive with the conversion-focused leaders. No momentum signal was recorded for this applicant.

Under-served branches in control, protection, and measurement
Several IPC classes adjacent to the dominant H02M cluster carry low patent record counts, representing relative sparsity that may have technical value for organisations working on industrial HVDC reliability and automation.
H02H · Protective circuit arrangements
H02H accounts for only 5 patent records and a 6% share within this corpus, despite fault protection being a critical engineering challenge in industrial HVDC systems where DC fault clearance is more complex than in AC networks. The sparse coverage, combined with the known technical difficulty of DC protection, suggests this branch could reward targeted filing by organisations with fault-detection or solid-state breaker expertise. General Electric Co is the only top-ranked applicant with H02H emphasis, leaving the space open for challengers.
Search this in Eureka →G05B · Control & regulating systems
G05B holds 5 patent records and a 6% share, indicating that automated control and regulation of HVDC converter systems for industrial loads is relatively unclaimed. As industrial plants adopt more dynamic load profiles and demand-side management, control-layer IP becomes strategically valuable. Only one applicant in the ranked field shows a primary G05B focus, leaving room for control-systems specialists or industrial automation firms to establish a position.

Frequently asked questions
The corpus covers 7 patent families in scope. The applicant ranking and IPC composition data are reported at the patent-record level, which can exceed the family count when a single family is filed across multiple jurisdictions or classes.
CET GRP SA leads with 16 patent records, followed by Ideal Power Inc with 8 patent records and General Electric Co with 5 patent records.
H02M (power conversion, including AC/DC and DC/DC circuits) is the dominant IPC class by a wide margin. H02J (power supply and grid systems) is a secondary cluster, with control, protection, and measurement classes each representing much smaller shares.
The evidence places this field at maturity, with annual filings plateaued near their peak. This indicates that foundational IP in converter topology is well-established and the pace of new filings has not accelerated in recent years.
The United States leads all jurisdictions by patent record count, followed by Europe (EPO) and India. Germany, Austria, WIPO (PCT), Canada, and Norway also appear in the filing record.
Veerabhadra Elite Electrodynamic Solutions LLP is flagged as a new entrant with 2 recent patent records, focusing on H01F (magnets, inductors, and transformers) and H02M7 (power conversion). No other applicants in the ranking show a recorded recent-filing acceleration trend.

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.
