CFRP Surface Coating & Film Patent Snapshot 2026
The CFRP surface coating and film space is a compact, mature field led by aerospace and materials incumbents, with Boeing and Toray Industries holding the top two positions and the top five filers accounting for 39% of the hundred largest filers’ combined output. Annual filing volume has plateaued near its 2019 peak, signalling a field that is consolidating around established technical routes rather than expanding into new ones.
Boeing leads a concentrated field anchored by aerospace and advanced materials players
Boeing holds the top position in this space, followed by Toray Industries and Hewlett Packard Development Company, establishing a clear three-tier hierarchy at the top of the applicant ranking.
The top five filers account for 39% of the ranked applicants visible in this query’ combined patent records, indicating moderate-to-high concentration with a meaningful gap between the leading trio and the broader group of smaller applicants below them.

Boeing’s dominance reflects its deep integration of coating and surface treatment into aircraft structural design, while Toray’s position underscores the materials science angle of the field; together they define the two primary technical orientations — aerospace application and composite laminate engineering.
Filings from approximately 2024 onward are subject to publication lag and may be under-represented; the apparent plateau in recent years should be interpreted with that constraint in mind. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filings plateaued after a 2019 peak; layered-product and coating-process classes dominate the technology mix
The annual filing trend reveals a field that surged briefly around 2019 and has since settled into a lower, steady cadence, while the technology composition chart shows a clear concentration in laminate and coating-process classes with a long tail of adjacent application areas.
Annual filing trend
Filings peaked in 2019 and have held at a reduced, near-flat level since; the most recent one to two years are likely under-counted due to publication lag and should not be read as a further decline. Growth over the measured window is flat at zero percent.

B32B (layered products and laminates) is the visible IPC class, followed by B05D (coating processes) and C09D (coatings, paints and inks); together these three classes account for the majority of classified records. Aerospace-specific classes B64D and B64C appear at lower but meaningful shares, confirming the field’s primary end-use orientation. A long tail of classes spanning pipes, lighting, motor vehicles, and armour reflects diverse secondary applications.

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. Treat this section as citation context, not as a curated list of the most topic-specific patents. 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.
The Boeing Company
Boeing holds 12 patent records, the highest in the corpus, concentrated in B05D coating processes and B64D aircraft equipment — a consistent focus on applying surface coatings directly to airframe structures. No recent momentum data is available beyond the existing base, placing Boeing as an established incumbent defending a mature position rather than a high-velocity filer.
families: 12Toray Industries Inc.
Toray holds 9 patent records, focused on B32B layered products and laminates and B29C shaping of plastics — a materials-engineering orientation distinct from Boeing’s application focus. This laminate-first approach positions Toray as the leading upstream materials supplier in the corpus, with IP covering how CFRP layers are structured rather than how they are coated in-service.
families: 9Frequently asked questions
The corpus covers 15 patent families. This is a relatively compact dataset, so rankings and concentration figures reflect a specialist sub-field rather than a broad technology category.
The Boeing Company is the leading applicant with 12 patent records, concentrated in B05D coating processes and B64D aircraft equipment classes, reflecting a focus on protective and functional coatings applied directly to airframe structures.
China is the lead filing jurisdiction with 27 patent records, ahead of Europe via the EPO with 9 and the United States with 7. WIPO PCT filings stand at 5, indicating some applicants are pursuing broad international protection.
The field is at a mature stage, with annual filings having plateaued near the 2019 peak. Zero percent growth over the measured window confirms that the core technical routes are well-established and that the field is not in an expansionary phase.
Two co-applicant pairs are identified. Shenzhen Oceans King Lighting Engineering and Oceans King Lighting Science & Technology have co-filed on 2 records, and BYK-Chemie Japan and Toyota Motor Corporation have co-filed on 2 records. Neither pairing involves the aerospace leaders Boeing or Airbus.
B64C (aeroplanes and helicopters, 4 records, 3% share) and C08K (use of additives in polymers, 6 records, 4% share) are among the lower-density classes adjacent to the visible B32B and B05D branches, representing areas where existing IP density is relatively low.

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.
