Thermoplastic Composite Process Automation Patent Landscape 2026
- Filing activity peaked in 2020 at 15 families and has since dropped back toward early-decade levels, with the 2022 midpoint at just 4 — this is a field that surged and cooled, not one still climbing.
- 69 families worldwide, concentrated in one office 38 of the tracked filings entered through the United States receiving office, more than three times the next largest route (Europe, 11).
- B32B lamination claims sit alongside B29C shaping in 21 records meaning a meaningful share of this art is being fought as much on layered-product structure as on process automation itself.
Filing growth compares 2021 (6 records) with 2024 (0) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 69 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This landscape tracks patent families at the intersection of thermoplastic composite materials and automated layup processes — automated fiber placement, automated tape laying and in-situ consolidation — filed under core shaping and lamination IPC classes (B29C70/38, B29C70/54, B29C70/32). It is a narrow, process-defined slice of composites manufacturing rather than a materials-only view: claims here typically bind a thermoplastic matrix to a specific machine step, tooling configuration or consolidation sequence.
The dataset spans 2015 through the 2026 cut-off, with publication lagging filing by roughly eighteen months, so the final one or two years will always look thinner than they eventually turn out to be once later filings publish.
69 published families is a small enough corpus that individual assignee moves and single well-cited documents carry disproportionate weight — a useful landscape for freedom-to-operate scoping, less useful for macro trend-spotting.
Filing trend and technology mix
Two views of the same 69 families: how filing pace has moved year over year, and which IPC subclasses the claims actually sit in.
A 2020 peak, then a pullback
Filings rose from 2 in 2017 to a peak of 15 in 2020, then fell back — the 2022 midpoint of 4 confirms this is a flat-to-declining trend rather than a technology still building momentum. Treat the final year or two as undercounted given publication lag.
Shaping and lamination dominate
Every record sits in B29C (shaping of plastics), and 21 of 69 also carry a B32B (layered products) tag — meaningful overlap between process claims and laminate-structure claims. Smaller counts in B29K, B29L, B29D and B29B reflect materials and article-index classifications riding alongside the core process claims, while B33Y (additive manufacturing) and F16C (bearings/couplings) mark small adjacent pockets — 5 records each — where thermoplastic composite automation is starting to touch 3D printing and structural mechanical parts.
Shares are the percentage of the 69 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Systems and methods of in-situ consolidation of AFP thermoplastic composites
A system and method for in-situ consolidation and secondary heating of automated fiber placement (AFP) thermoplastic composites is disclosed. The system employs a dual-stage process wherein thermoplastic composite material is first deposited onto a mold using an AFP machine with a first compaction tool and first heater optimized for layup operations, followed by a separate consolidation pass using a second compaction tool and second heater specifically configured for consolidation. During the consolidation pass, the mold is heated above the glass transition temperature (Tg) of the thermoplastic composite material to enhance consolidation effectiveness. The system allows independent optimizatAbstract truncated as published.

Citation counts inside this corpus skew toward earlier filings by construction — a 2015 or 2016 document has had a decade to accumulate citations that a 2024 filing has not. Read the table as a map of foundational, frequently-referenced claim language, not as a ranking of current importance.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register. Each row carries its publication number; clicking a row searches Eureka by that number.

Three cuts on the same 69-family dataset, aimed at where to file next and where not to bother.
The surge has already happened
Filing activity peaked in 2020 and has not returned to that level since. A field that peaked several years ago and cooled is not necessarily dead, but a new entrant should not assume they are arriving early.
Protection is US-centric
More than half of tracked families entered through the United States receiving office, with Europe a distant second at 11. Applicants defending only a US position may be leaving Canadian, Chinese and Australian filing gaps genuinely open rather than merely under-filed.
Process claims lean on laminate structure
Nearly a third of records combine a B29C process claim with a B32B layered-product claim, suggesting the strongest filing strategy in this space pairs a process step with a specific laminate architecture rather than claiming the process alone.
Additive manufacturing and structural parts are minor, not absent
Small but nonzero overlap with additive manufacturing (B33Y) and bearings/couplings (F16C) IPC classes shows this process automation art is starting to bleed into 3D-printed composite structures and load-bearing mechanical parts, at low volume so far.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to thermoplastic composite process automation, with the prior art for and against each one.
Who is filing, and who has slowed down
Recent-year momentum tells a different story from historical citation counts: several of the most cited or best-known names show no new filings in the latest tracked year, while activity has thinned across the board.
Flat, low-volume activity at the front
ArianeGroup SAS (ArianeGroup) and Wichita State University each logged a single filing in the latest year with no year-on-year change — steady but not accelerating.
A visible pullback
Spirit AeroSystems, Inc. shows zero filings in the latest year against a prior positive base, a full year-on-year drop that is worth checking against that assignee's broader portfolio before reading too much into it.
Established names have gone quiet
Cytec Industries Inc. (Cytec Industries), Trelleborg Sealing Solutions US, Inc. and The Boeing Company (Boeing) all show zero filings in the latest tracked year. For a corpus this size, that is consistent with the broader post-2020 pullback rather than exit from the field.

| ArianeGroup SAS | 1 | 0% |
| Wichita State University | 1 | 0% |
| Cytec Industries Inc. | 0 | — |

Where to take this
Two directions to go from here, depending on whether the question is technical scoping or freedom-to-operate.
Map the white space precisely
The gate chips above point to sub-areas with thin filing density inside a small, process-defined corpus. Before designing around them, run the specific claim language against the full family set rather than the citation table alone.

The core process claims sit under B29C70/38, B29C70/54 and B29C70/32, all within the broader B29C class for shaping plastics. A substantial share of records — 21 of 69 in this dataset — also carry a B32B layered-products classification, because automated fiber placement and tape laying claims often specify the resulting laminate structure alongside the process steps. Smaller counts appear in B29K and B29L, which are material and article index classes rather than standalone process claims, and in B33Y where additive manufacturing overlaps with thermoplastic composite layup.
Not currently, based on this corpus. Filing activity rose from 2 families in 2017 to a peak of 15 in 2020, then declined to 4 by the 2022 midpoint — a flat-to-declining pattern rather than sustained growth. The most recent one or two years will read artificially low because publication typically lags filing by around eighteen months, so some 2025-2026 activity has not surfaced yet. Even accounting for that lag, the trend since 2020 points to a cooling rather than an accelerating field.
The United States receiving office accounts for 38 of the 69 tracked families, more than three times the next largest route, Europe at 11. Canada and the WIPO PCT route each carry 4, with China at 3 and Australia at 2. That imbalance suggests US filing is close to a baseline expectation in this field, while Canadian, Chinese and Australian coverage may be genuinely thinner rather than simply under-tracked, worth checking directly against your own competitive set before assuming they are open.
The published abstract describes a dual-stage automated fiber placement process: a first pass with a compaction tool and heater tuned for layup, followed by a separate consolidation pass with its own compaction tool and heater that heats the mold above the thermoplastic's glass transition temperature. Because it separates layup and consolidation into independently optimized stages, any process that follows the same two-stage sequence with independently tuned tooling should have its claim scope checked directly rather than assumed clear. Filed by Wichita State University and published 2026-01-29, it is the most recent addition to this landscape and sits inside the in-situ consolidation sub-area flagged as active in the underlying data.
Citation counts accumulate over time within a searched corpus, so a document published in 2015 or 2016 has had roughly a decade longer to be cited than one published in 2024 or 2025. The most-cited records in this dataset are concentrated in the 2015-2018 range for exactly this reason — it reflects age and visibility, not necessarily present-day relevance. Use the citation table to identify foundational claim language that later filings had to design around, and use the filing-trend and IPC data separately to judge what is currently active.
