Metamaterials Patents: Who Leads, Where the Gaps Are 2026
- Concentrated but not locked up. the leading assignee alone accounts for 59 of 836 records, yet the top 5 combined hold only 25.4% of all filings — a long tail of single- and few-filing entrants still has room to move.
- Filing has cooled from its 2017 peak. the peak year of 92 filings has not been matched since, and the 2021–2024 window shows a 15% decline — though 2025–2026 figures are still filling in due to publication lag.
- Optics and antennas dominate, medicine and coatings trail. G02B (optical elements) and H01Q (antennas) each cover roughly 12% and 11.6% of the 836 records, while A61K and C23C sit closer to 7% — a gap that signals where claim space is thinner.
Filing growth compares 2021 (55 records) with 2024 (47) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 836 records in scope (CR5), not by the ranked leaders only.
What the metamaterials patent record actually shows
Metamaterials patenting spans structural, electromagnetic and acoustic engineering, and the 836 records in scope reflect that breadth: filings touch optics, antennas, additive manufacturing, semiconductor devices, nanotechnology, medicinal preparations and surface coatings. No single application dominates the way it might in a narrower field, which is itself informative — the underlying structural concepts are being adapted across industries faster than any one player can claim them outright. Patent families, not raw document counts, are the fairer unit here, and the assignee ranking in this dataset is already expressed in those terms.
Filing activity peaked in 2017 and has not returned to that level since, though the most recent one to two years are structurally undercounted because publication typically lags filing by around 18 months. Reading the trend as a definitive slowdown would be premature; reading it as evidence that no single wave of consolidation has yet occurred is safer and better supported by the concentration figures below.
Filing trends and technology composition
Two views of the same 836-record dataset: the pace of filing over time, and the IPC subclasses those filings fall into. Because a single record can carry several IPC classes, the composition shares add up to more than 100% of the record total.
Filing trend, 2017–2026
Filings peaked at 92 in 2017. The 2021-to-2024 window, the most recent period that can be treated as complete, shows a move from 55 to 47 filings — a 15% decline. Years beyond 2024 are still filling in as publications catch up to filing dates.
Technology composition by IPC subclass
Optical elements (G02B, 12.0% of the 836 records) and antennas (H01Q, 11.6%) lead the composition, followed by additive manufacturing (B33Y, 7.8%), semiconductor devices (H01L, 7.7%), material analysis (G01N, 7.3%), nanotechnology applications (B82Y, 7.2%), medicinal preparations (A61K, 7.1%) and coatings (C23C, 6.8%).
Shares are the percentage of the 836 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

EP4030420B1 — Acoustic metamaterial and method for its manufacture
Filed by Centre Internacional de Metodes Numerics a l'Enginyeria and granted in mid-2023, this filing addresses acoustic metamaterial structures and their manufacturing method — a domain that sits outside the optics- and antenna-heavy centre of gravity in this dataset.Original title filed in German: "Akustisches Metamaterial und Verfahren zu seiner Herstellung."

Three patterns stand out once the ranking, trend and IPC composition are read together: concentration is moderate rather than extreme, the field's growth curve is bending rather than climbing, and the technology mix skews heavily toward optics and RF applications relative to medical or coatings use.
No single assignee controls the field
The leading assignee holds 59 records, and the top 5 combined reach 212 records — 25.4% of the 836 in scope. That leaves roughly three-quarters of filings spread across the remaining ranked entrants, including many single-filing organisations.
Growth has not sustained its 2017 peak
Filings dropped from 55 in 2021 to 47 in 2024, a 15% decline over that span. The peak year of 92, in 2017, has not been revisited, though 2025-onward counts are still incomplete due to publication lag.
Optics and antennas anchor the field
G02B and H01Q together cover the largest shares of the 836 records, at 12.0% and 11.6% respectively. Additive manufacturing, semiconductor devices and nanotechnology applications each sit in the 7-8% range, with medicinal preparations and coatings trailing near 7%.
Filing is US-centred with strong PCT and EPO use
The United States receives 353 filings, well ahead of Europe (EPO, 139) and WIPO/PCT (139). India, Canada and Germany form a secondary tier at 40, 28 and 28 respectively.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to metamaterials patent landscape, with the prior art for and against each one.

Ten co-assignee pairs appear in the dataset. The strongest pairing spans a US research institution and a nanotechnology company, with weaker pairs linking a university and a nanotechnology firm, and an energy company with an individual inventor — evidence of applied, cross-organisation development rather than isolated academic filing.
Who is filing, and where the gaps sit
The ranked leaders span universities, research foundations and materials or energy companies rather than a single industry vertical. Recent-year momentum across several of the top-ranked assignees shows zero new filings in the latest year, consistent with the broader 2021-2024 decline and the publication lag affecting the most recent period.
Universities and research foundations set the pace
Medical research foundations and university research corporations occupy several of the top ranked positions, reflecting metamaterials' roots in fundamental electromagnetic and acoustic research before commercial application.
Company-university pairs push toward application
The strongest co-assignee pairing in the dataset links a university research corporation with a nanotechnology company, suggesting joint development moving lab-scale metamaterial structures toward manufacturable form.
Most of the field sits outside the ranked leaders
With the top 10 combined holding 36.6% of the 836 records, the majority of filings belong to organisations outside that group — a fragmented landscape where a well-drafted claim can still find open ground.

Where to take this analysis
The dataset points to specific next steps depending on whether the goal is freedom-to-operate, licensing or new filing strategy.
Check claim scope against the most-cited records
The highest-citation filings, several from the late 2000s and early 2010s, still anchor foundational claim language in optics and waveguide structures. Any new filing in those areas should be checked against them before drafting.
Explore citation network in EurekaModel the under-claimed branches
Acoustic structures, medicinal applications and coating-focused claims show thinner IPC coverage than optics or antennas. A first claim drafted around one of these branches has more room to establish novel scope.

Among the 836 records in this dataset, a single research foundation leads with 59 records, ahead of a field of universities, research corporations and materials or energy companies. The top 5 assignees combined hold 212 records, or 25.4% of all 836 records in scope, which means the field is led but not dominated by any one organisation. The remaining three-quarters of filings are spread across a long tail of 100 ranked entrants, many with only a handful of filings each.
Filing activity peaked in 2017 at 92 records and has not returned to that level since. Looking at the most recent complete window, filings fell from 55 in 2021 to 47 in 2024, a 15% decline. It would be a mistake to read the years after 2024 as confirming further decline, however, because patent publication typically lags filing by around 18 months, so the most recent one to two years in any dataset are always undercounted.
Optical elements and systems (IPC class G02B) lead at 12.0% of the 836 records, closely followed by antennas (H01Q) at 11.6%. Additive manufacturing, semiconductor devices, material analysis, nanotechnology applications, medicinal preparations and surface coatings each account for roughly 7-8% of records. Because a single patent can be tagged with multiple IPC classes, these shares add up to more than 100% of the record total, reflecting how metamaterials concepts get applied across several downstream fields simultaneously.
Relative to the optics- and antenna-heavy core of the field, sub-areas like acoustic metamaterial waveguide structures, drug delivery scaffolds built on metamaterial principles, and additive-manufactured negative-index lattices show thinner IPC coverage. A first claim in one of these branches has more open ground to work with than a claim filed against the dense optics or antenna prior art. That said, thinner coverage in a given IPC class does not guarantee an easy grant — it simply means fewer competing claims to design around.
EP4030420B1, granted in mid-2023 to Centre Internacional de Metodes Numerics a l'Enginyeria, covers an acoustic metamaterial structure and its method of manufacture. It is a useful reference point because it sits in the acoustic branch of the field rather than the more heavily filed optical or antenna branches, and its granted claims illustrate how manufacturing-method language can be used to secure protection even in a comparatively less crowded sub-area.
