Thermoplastic Composite Aerostructures Patents: Leaders & White Space 2026
Thermoplastic Composite Aerostructures Patents: Who Holds the Ground
Concentrated at the top. The top 5 assignees hold 191 of 389 records in scope (49.1%), and the top 10 hold 269 (69.2%) — this field is not a wide-open field of small filers. Filings rose to a peak of 64 in 2019, then eased; the most recent complete comparison — 16 filings in 2021 against 15 in 2024 — is a -6% move, not a collapse. Treat 2025 and later years as still filling in.

Common questions on this landscape
Who holds the most patents in thermoplastic composite aerostructures?
One assignee leads the ranked field with 64 records, well ahead of the fifth-place company’s 18. The top 5 assignees together hold 191 of the 389 records in scope, 49.1%, and the top 10 hold 269, 69.2%. That is a concentrated field: a small number of companies, spanning an aerospace OEM, specialist materials suppliers and a defence prime, account for most of the documented filing activity, and any new filer should expect to be drafting around their existing claims rather than into open space.
Is patent filing in this field growing or shrinking?
Filing peaked at 64 records in 2019 and has since eased; comparing the two most recent complete years, 2021’s 16 filings fell to 15 in 2024, a -6% move. That is a modest pullback rather than a collapse, and it should not be read as the technology losing relevance. Because publication lags filing by roughly 18 months, the 2025 and 2026 figures in any chart are still incomplete and will rise as more records publish.
What manufacturing processes does this patent set actually cover?
The search scope combines thermoplastic material forms — PEEK composite, thermoplastic laminate, thermoplastic prepreg — with the processes used to consolidate and join them: consolidation temperature control, fusion bonding, in situ consolidation, crystallinity control, resistance welding and induction welding. In IPC terms that shows up as heavy weighting toward B29C (shaping of plastics, 56.3% of records) and B32B (layered products, 26.5%), with welding-specific claims under B23K a much narrower 5.9% of records.
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 Thermoplastic Composite Aerostructures 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.
