Metamaterial and Frequency Selective Surface Patents
Filings grew 61% from 2021 to 2024 (33 → 53) the fastest sustained run in the dataset's decade of coverage, before the usual 18-month publication lag understates the last two years. Annual filings rose from 8 in 2017 to a peak of 53 in 2024, with the +61% run between 2021 and 2024 marking the steepest sustained climb in the window. 2025 and 2026 counts (including 14 so far in 2026) will revise upward as pending publications clear the pipeline.

Common questions on this landscape
How many companies actively file frequency selective surface and metamaterial absorber patents?
The assignee ranking in this dataset covers 100 companies, counted by patent records, and it is the full ranking the underlying data endpoint returns rather than a curated top list. The leader holds 23 records, fifth place holds 12, and tenth place holds 9 — a gradual taper rather than a sharp cliff. That distribution, combined with the fact that the top 5 assignees together hold only 20.0% of all 415 records in scope, indicates a field with room for new entrants rather than one locked up by a handful of incumbents.
Is filing activity in this field increasing or slowing down?
Filing activity has been accelerating, not slowing. Annual filings rose from 8 in 2017 to a peak of 53 in 2024, and the +61% growth recorded between 2021 and 2024 is the steepest sustained climb in the dataset's coverage window. The 2025 and 2026 figures look lower, but that reflects the roughly 18-month lag between filing and publication, not a genuine drop in activity — 2024 is the most recent year that can be treated as a complete signal.
Which patent classes dominate metamaterial and FSS filings?
H01Q, the antenna subclass, appears in 70.4% of the 415 records in scope, making it by far the dominant framing for this technology. G02B (optical elements, 16.1%) and H01P (waveguides and microwave elements, 14.5%) are the next most common, followed by H05K (printed circuits, 10.6%) and H04B (transmission, 8.4%). Because a single record can carry multiple IPC classes, these shares add up to well over 100% and should be read as overlapping technical framings rather than mutually exclusive categories.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Metamaterial and Frequency Selective Surfaces covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
