Thermoplastic Composite Design Optimization Patent Landscape 2026
A narrow, still-forming claim space
The intersection of thermoplastic composite materials with computational design optimization — layup optimization, topology optimization, draping simulation, structural optimization — is claimed in only two published patent families as of this cut-off. That is not a sign the underlying engineering problem is small; thermoplastic composite layup and topology work is active across aerospace, automotive and satellite hardware programs. It is a sign that very few filers have chosen to claim the optimization method itself alongside the material system, rather than claiming the resulting part or the material composition on its own.
Both records in scope classify under B64G (cosmonautics and spacecraft) and G06F (electric digital data processing), which points to a specific use case — structural optimization of composite spacecraft hardware — rather than a general-purpose design tool. Publication lags filing by roughly eighteen months, so any 2025–2026 filings that exist are not yet visible here.
Filing trend and technology mix
Two records, one filing spike, and a technology footprint concentrated in spacecraft structures rather than general composite manufacturing.
Flat trend with a single peak
Filings were at zero through 2017 and stayed there for most of the window; the only activity recorded is a peak of two records in 2023, with the 2022 midpoint still at zero. There is no visible acceleration into the most recent, still-incomplete year.
Two codes, one application context
Every record in scope carries both B64G (cosmonautics and spacecraft) and G06F (electric digital data processing) codes, indicating the optimization claims here are anchored to spacecraft structural hardware rather than to composites design tooling in general.
Shares are the percentage of the 2 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Vibration isolation/damping satellite mount made of chopped carbon fiber reinforced thermoplastic composite material
A vibration isolation/damping satellite mount of a chopped carbon fiber reinforced thermoplastic composite material mainly includes two parts, connected through bolts. Considering the limitation of the molding process, the mount configuration is further optimized, and the mount structure is prepared using an injection molding process. The mount is designed for large loads and complex working conditions, with attention to connectivity, overall strength stability, vibration isolation performance and service life.Abstract condensed from the granted filing; see the full text for claim language.

With only two records in scope, citation counts here reflect a single comparison, not a competitive ranking.
Publication numbers are shown where the record carries one (1 of 1 rows); clicking a row searches Eureka by that number.

A dataset this small still carries signal — it tells you the claim space is essentially open, and where the one active filer has staked ground.
The claim space is effectively unclaimed
Two families across an eleven-year window means most layup, topology and draping-simulation approaches applied to thermoplastic composites have not been claimed as such. A freedom-to-operate search here will find little to clear, but that also means there is little precedent to build a claim strategy against.
One filing burst, not a trend
All recorded activity clusters in a single year. A midpoint of zero in 2022 and no visible follow-through means this looks like an isolated filing event tied to one program rather than the start of a sustained wave.
Spacecraft structures, not general manufacturing
Both records carry spacecraft-cosmonautics and digital-processing codes together, which suggests the optimization claims here were built for satellite hardware design specifically, not for thermoplastic composite manufacturing broadly.
US-only filing so far
Every record in scope was filed through the United States receiving office. There is no visible parallel filing in other jurisdictions, which either reflects the scope of this search or a genuinely US-centric filing strategy by the one active assignee.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to thermoplastic composite design optimization, with the prior art for and against each one.
Where to look next
With only two families in scope, the next useful step is widening the search rather than ranking within it.
Broaden beyond spacecraft codes
Searching without the B64G constraint would surface thermoplastic composite optimization claims filed for automotive, wind-energy or general aerospace structures, which are likely classified differently but may use identical simulation methods.
Explore adjacent IPC codesTrack the lead assignee's other filings
Dalian University of Technology's broader composite materials portfolio, outside this narrow claim intersection, may reveal whether the design-optimization approach here extends into other part types.
Review assignee portfolioRe-run after the lag window closes
Filings from 2024 onward are still working through the roughly eighteen-month publication lag; revisiting this search in a year will show whether 2023's burst had any follow-through.
Set a monitoring alertCommon questions
Within the specific claim intersection tracked here — thermoplastic or thermoplastic-matrix composites claimed together with layup, topology, draping-simulation or structural optimization language, under IPC codes B29C70, B32B5 or G06F30 — there are only two published patent families as of the 2026-07-31 cut-off. This is a narrow, deliberately bounded search rather than a measure of all composite optimization activity; broader searches without the optimization-language requirement would return far more records. Treat the two-family count as evidence that few filers have chosen to claim the design method itself alongside the material system.
Dalian University of Technology is the only assignee identified in this dataset, holding both of the two published families in scope. Its most-cited record covers a vibration isolation and damping satellite mount made of chopped carbon fiber reinforced thermoplastic composite material, optimized for an injection molding process. No other assignee has filed within this exact claim intersection during the coverage window, and recent-year data shows no new activity from Dalian University of Technology either.
US11878821B2, assigned to Dalian University of Technology and granted in January 2024, claims a vibration isolation and damping satellite mount built from chopped carbon fiber reinforced thermoplastic composite material, formed from two bolted parts and shaped by an injection molding process with the mount configuration optimized for that process. Its scope is tied to a specific structural application — spacecraft mounting hardware under large loads and complex working conditions — rather than to composite design optimization methods in general. Someone working on injection-molded thermoplastic composite brackets for non-spacecraft use would need to review the claim language closely, but the application context here is narrow.
Not on the evidence available. Filing was at zero for most of the tracked window, reached a single peak of two records in 2023, and the 2022 midpoint sits at zero, meaning the trend line is flat rather than climbing. This looks like an isolated filing event rather than the start of a sustained wave, though the most recent one to two years are always undercounted because publication typically lags filing by around eighteen months.
Because only two families occupy this intersection and both are anchored to spacecraft structural hardware, adjacent branches such as draping simulation for thermoplastic tape layup, topology optimization of injection-molded composite brackets outside aerospace, and layup-path optimization tied to automated fiber placement show no dedicated claims in this dataset. That does not guarantee freedom to operate — broader material or part-level patents may still apply — but within this specific method-plus-material claim style, the space is largely unclaimed. A first mover claiming a specific optimization algorithm applied to a named thermoplastic composite process would be filing into largely open ground.

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.
