HEA Standardization Patent Snapshot 2026
The patent corpus for HEA standardization is extremely nascent, with only 3 patent families in scope spread across a small group of individual inventors and academic institutions. Activity is highly fragmented, with no single dominant route or corporate leader, and the field remains largely open to early-mover positioning.
A nascent field with no dominant applicant
The leading filer, Dr. Bommana Shravan Kumar, holds 1 patent record — the same count as every other applicant in the ranking. No single organization has established a meaningful lead in this space.
The top five filers collectively account for 83% of the combined total among the ranked applicants visible in this query, yet in absolute terms this reflects a very thin corpus. The apparent concentration is an artifact of the field’s early stage rather than a sign of entrenched incumbents.

The absence of large corporate assignees and the presence of individual inventors and regional universities signals that HEA standardization, as a distinct patent category, has not yet attracted sustained institutional R&D investment. This leaves the assignee snapshot structurally open.
The most recent filings (2025–2026) are subject to normal publication lag and likely under-represent current activity; the true scope of recent filing may be higher than the corpus currently reflects. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sparse filing history with a broad but shallow technology mix
The annual filing trend reveals isolated activity rather than a sustained wave, and the technology composition spans six IPC classes with equal weight — indicating exploratory, multi-directional research rather than a converging technical consensus.
Annual filing trend
Filing was absent from 2017 through 2021, with a single record appearing in 2022, a gap in 2023–2024, and single records in both 2025 and 2026. The 2025–2026 data points are subject to publication lag and should not be read as a peak or trough. No sustained upward trend is established.

Six IPC branches each hold exactly one patent record: powder metallurgy (B22F), non-metallic elements and inorganic compounds (C01B), alloys (C22C), coating and surface deposition (C23C), nuclear reactors (G21C), and nuclear power plants (G21D). The even distribution confirms that no single technical route has yet attracted concentrated investment.

A laser cladding dual-phase high-entropy alloy coating and a preparation method thereof are provided. The laser cladding dual-phase high-entropy alloy coating includes the following raw materials in atomic percentage: 9 to 16 percent (%) of aluminum (Al), 11 to 17% of chromium (Cr), 11 to 18% of iron (Fe), 13 to 20% of titanium (Ti), 10 to 15% of vanadium… (excerpt from the patent abstract)

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Dr. Bommana Shravan Kumar
The top-ranked applicant by name in the corpus, with 1 patent record focused on non-metallic elements and inorganic compounds (C01B), nuclear reactors (G21C), and nuclear power plants (G21D). This technical orientation suggests HEA-related work directed at nuclear materials applications. No momentum data is available for this applicant beyond their single filing.
patent records: 1Institute of Metal Research, Chinese Academy of Sciences
The most notable momentum signal in the corpus belongs to the Institute of Metal Research under the Chinese Academy of Sciences, flagged as a new entrant with 1 patent record in the recent period. Their technical focus is squarely on alloys (C22C 1 and C22C 30), which represents the most direct alignment with conventional HEA materials science. Their entry warrants monitoring as a potential indicator of broader institutional interest from China.
patent records: 1Frequently asked questions
The current corpus contains 3 patent families in scope. This is an extremely small base and should be interpreted as evidence that HEA standardization is not yet an established patent category attracting systematic filings.
Dr. Bommana Shravan Kumar is the top-ranked applicant with 1 patent record. Every other applicant in the ranking also holds 1 patent record, so the ranking reflects alphabetical or indexing order rather than a meaningful portfolio gap.
Patent records have been filed in three jurisdictions: China, India, and the United States, with one record each. China is the lead office. Coverage is minimal and does not constitute broad international protection by any applicant.
The six IPC classes represented are powder metallurgy (B22F), non-metallic elements and inorganic compounds (C01B), alloys (C22C), coating and surface deposition (C23C), nuclear reactors (G21C), and nuclear power plants (G21D). Each holds exactly one patent record, indicating broad but shallow technical coverage.
No co-filed or jointly assigned patents appear in the corpus. All filings are attributed to individual inventors or single institutions acting independently. Collaborative R&D in this area, if it exists, has not yet produced co-assigned patent filings.
There were zero filings from 2017 through 2021, a single record in 2022, no records in 2023–2024, and single records in 2025 and 2026. The 2025–2026 data are subject to publication lag. The pattern is consistent with isolated, exploratory work rather than a developing growth 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. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
