Thermoplastic Composite Coating Patent Snapshot 2026
The thermoplastic composite coating patent space is moderately concentrated, with Azdel Inc holding a clear lead among the top hundred filers and layered-product laminates dominating the technology mix. Filing volume peaked in 2021 and has since eased, signalling a field in decline where differentiated process and formulation claims still offer selective entry points.
Azdel leads a field with a visible tier gap below the top two
Azdel Inc ranks first among the ranked applicants visible in this query, followed by Intercontinental Great Brands LLC and EI du Pont de Nemours & Co. The top five together account for 35% of the combined patent records held by the ranked applicants visible in this query, indicating moderate-to-high concentration at the top.
A clear tier gap separates the top two applicants from the rest of the ranked field. Below the top five, holdings drop off gradually across a long tail of smaller corporate and individual filers, suggesting limited second-tier pressure on the leaders.

Azdel’s position, grounded in layered-product and plastics-shaping classes, reflects sustained investment in glass-mat and structural composite technology. Intercontinental Great Brands’ presence highlights that thermoplastic composite coating extends into food-contact and packaging substrates, a distinct application segment from the structural materials held by the industrial leaders.
Patent records filed in approximately the last 18–24 months are subject to publication lag and likely under-represent current activity; the most recent annual figures should be treated as provisional. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing volume peaked in 2021; laminates dominate technology mix
Annual filing activity and the IPC class breakdown together reveal where the field has matured and where thinner coverage persists. Both charts draw from the same 30-family corpus supplemented by multi-jurisdiction patent records.
Annual filing trend
Recorded filings were negligible in 2017–2018, rose to a peak of 11 records in 2021, then fell back to low single digits in 2022–2025. The 2024–2026 bars are subject to publication lag and should not be read as a confirmed trough; the field’s lifecycle is characterised as declining from its 2021 peak.

B32B (layered products and laminates) accounts for the largest share of IPC class references by a wide margin, followed at a distance by B29C (shaping of plastics) and C08J (polymer processing and solutions). Coating-specific classes B05D and C09D each carry notably lower record counts, pointing to relative sparsity in pure coating-process and paint-formulation claims compared with the structural laminate core.

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.

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.
Azdel Inc
Azdel Inc ranks first with 15 patent records, concentrating its claims in B32B 27 (layered products), B32B 5, and B29C 31 (shaping of plastics). This focus on glass-mat thermoplastic composite substrates and structural laminates reflects deep, long-standing coverage of the field’s foundational technology. No momentum trend data is available for Azdel in the evidence.
patent records: 15The Boeing Company
The Boeing Company holds 8 patent records and is identified as a new entrant in the recent filing window, with 4 recent records against a negligible prior base. Boeing’s technology emphasis sits in B32B 27, B32B 37, and B32B 7 — laminate construction and bonding methods — consistent with aerospace structural panel applications. The new-entrant trajectory warrants monitoring for continued build-out in aerospace composite coating.
patent records: 8Frequently asked questions
The corpus covers 30 patent families. Jurisdiction and IPC class reference counts are at the patent-record level and can exceed the family total because a single family is typically filed across multiple offices and assigned multiple class codes.
Azdel Inc is the top-ranked applicant with 15 patent records among the ranked applicants visible in this query, ahead of Intercontinental Great Brands LLC at 10 records and EI du Pont de Nemours & Co at 9 records.
The field is assessed as being in Decline, with annual filing volume having eased back from its 2021 peak of 11 records. The most recent years (2024–2026) carry under-counted records due to publication lag and should not be interpreted as a further acceleration of the decline.
B32B (layered products and laminates) is visible in with 106 IPC class references across the corpus, well ahead of B29C (shaping of plastics) at 40 references. Coating-specific classes B05D and C09D each carry 14 and 12 references respectively, indicating relatively thin coverage in pure coating-process claims.
The United States leads with 36 patent records, followed by Europe (EPO) with 30 records and WIPO (PCT) with 20 records. Australia and Canada hold secondary coverage at 11 and 8 records respectively. China holds only 2 records despite being a major composites manufacturing base.
Yes. The most active co-filing pairs each share 6 jointly filed records: Kosen Composite Materials with Bayer MaterialScience LLC, Kosen Composite Materials with Covestro (Taiwan) Ltd, and Bayer MaterialScience LLC with Covestro (Taiwan) Ltd. These three pairs form a single Covestro-family cluster. Boeing and CSIRO represent the only cross-industry/academic pairing, with 1 co-filed record.

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.
