Composite Wing Spar and Rib Assembly Patents: Leaders & Trends 2026
Composite Wing Spar and Rib Assembly Patents
A single leader holds 32 families while the next four ranked assignees sit far behind at fifth place with just 4 — a steep drop-off rather than a gradual tail. Filings rose from 2 in 2017 to a peak of 11 in 2021, then fell to 3 by 2024 — a 73% drop across that three-year window. 2025 and 2026 counts are still incomplete due to publication lag and should not be treated as confirming a further slowdown.

Common questions about this landscape
Who holds the most patents on composite wing spar and rib assembly?
One assignee leads the ranked field with 32 families, well ahead of the fifth-ranked company at 4. The ranking covers 13 companies total returned by the dataset, so it should be read as the full set of ranked filers in scope rather than a top-50 or top-100 list. This gap between the leader and everyone else suggests a long-running, deliberate filing programme rather than sporadic activity.
Is patent filing in this area still growing?
No — filings peaked at 11 in 2021 and had fallen to 3 by 2024, a 73% decline over that three-year window, which is the most recent period that can be treated as complete. Counts for 2025 and 2026 look lower still, but that reflects the roughly 18-month lag between filing and publication rather than a confirmed further drop. Anyone tracking this space should expect the 2025-2026 figures to revise upward as more records publish.
What technology areas are most heavily claimed?
B64C, the aeroplane and helicopter structures classification, appears on 53.2% of the 79 records in scope, making it by far the densest single class. B64F, covering ground installations for aircraft, follows at 24.1%. Polymer chemistry classes and machine-tooling classes each stay under 15%, meaning claim density there is comparatively lower even though those areas are directly relevant to bonded joints and liquid shim processes.
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.
