High-Performance Polymers Patents: Top Companies & Trends 2026
- 20.3% sits with five companies. 982 of 4,842 records in scope belong to the top five ranked assignees, with a long tail of single- and few-filing entrants behind them.
- Filing activity has pulled back sharply from its 2017 peak. The peak year was 2017 at 285 filings, and 2021-to-2024 volume fell 66% (185 to 62) — though 2025 onward is still filling in as publications lag filing.
- Polymer composition and condensation chemistry dominate the claim space. C08L and C08G together touch roughly half of all records, while shaping and layered-product classes remain comparatively open.
Filing growth compares 2021 (185 records) with 2024 (62) — 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 4,842 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This dataset tracks 4,842 published records matching high-performance and engineering polymer terminology alongside processing, morphology and mechanical-property language — spanning filings from 2015 through the 2026 data cut-off. The scope favours documents that tie polymer composition claims to a measurable property or process step, rather than polymer chemistry in the abstract.
Reading the assignee ranking and IPC mix together shows a field where a handful of specialty-chemicals incumbents hold a meaningful share of the record count, but where most of the 100 ranked companies appear with only a handful of filings each. That combination — real concentration at the top, thin claims everywhere else — is what the sections below unpack.

Filing trend and technology composition
Two views of the same 4,842 records: how filing volume has moved year over year, and which IPC subclasses carry the claim density.
Filing trend, 2017 peak to present
Filings peaked at 285 in 2017. The 2021-to-2024 window shows a 66% decline, from 185 to 62 — the last span both years can be treated as essentially complete given the roughly 18-month publication lag. Years from 2025 onward will fill in further and should not yet be read as a continued slide.
IPC subclass distribution
C08L (polymer compositions) and C08G (condensation polymers) lead at 26.1% and 23.4% of the 4,842 records respectively, with C08K (additives) close behind at 18.4%. Processing and shaping classes — C08J, B29C — sit lower at 12.1% and 11.5%, and layered-product claims under B32B cover just 7.3%, suggesting composition claims are far more contested than downstream forming or lamination steps.
Shares are the percentage of the 4,842 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Three read-outs from the concentration, trend and citation figures above.
Real concentration, but not a lockout
The top five ranked assignees hold 982 of 4,842 records — a fifth of the field — while the tenth-ranked company sits at only 79. That gap between fifth and tenth place, and the long tail behind it, means composition space is contested at the top but still accessible for narrower, application-specific claims.
Volume has cooled from its 2017 high
Filing activity peaked at 285 in 2017 and had fallen to 62 by 2024, a 66% drop across the last fully comparable three-year span. Recent-year momentum by assignee shows several leading filers at zero or sharply down year-on-year, consistent with a maturing composition-claim base rather than a newly active one.
Composition claims outweigh processing claims
C08L and C08G together are the two most-populated IPC subclasses, well ahead of shaping (B29C, 11.5%) or layered products (B32B, 7.3%). Processing and lamination routes carry proportionally less claim density, which is where a well-drafted process or laminate claim has more room to stand apart.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to high-performance polymers patent landscape, with the prior art for and against each one.
Who is filing, and where activity has slowed
The ranking spans 100 companies by record count. A few incumbents hold double-digit shares; most of the ranked list files only occasionally.
One clear leader ahead of a tight next tier
The top-ranked assignee holds 280 records, well ahead of the fifth-place company at 144 and the tenth-place company at 79 — a steep early drop-off followed by a flatter tail across the rest of the ranking.
Several top filers have gone quiet recently
Recent-year momentum shows multiple previously active assignees, including specialty-polymer and petrochemical filers, at zero filings in the latest year, with year-on-year declines of 50% to 100% among those still filing at all.
Co-filing is limited and concentrated
Only ten co-assignee pairs appear in the dataset, and the strongest of them cluster around one research-arm assignee working with named individual inventors — a pattern of internal co-invention rather than cross-company joint filing.

| Lanxess | 2 | — |
| UOP LLC | 1 | -50% |

Where to take this analysis
The dataset points to specific next steps depending on whether you are clearing freedom-to-operate or scouting where to file.
Map claim scope against the leader's portfolio
With one assignee holding 280 records, checking claim scope against that portfolio before drafting composition claims avoids overlap with the densest single filer in the field.
Explore assignee portfolios in EurekaTrack the momentum shift
Several leading filers show zero filings in the latest year. Confirming whether that reflects licensing, acquisition, or a genuine pullback changes how much weight to put on their older claims.
Run a momentum check in EurekaTest white space in shaping and lamination
Processing and layered-product classes carry proportionally less claim density than composition classes. A targeted search in those subclasses can confirm how much room remains before drafting.

One assignee leads the ranked list with 280 records out of 4,842 in scope, well ahead of the fifth-ranked company at 144 and the tenth at 79. The top five combined hold 20.3% of all records, so while there is a clear leader, the remaining share is spread across a long tail of the other 95 ranked companies. This pattern points to real but not exclusive control of the claim space — smaller filers still have room to establish position with narrower claims.
Filing volume peaked in 2017 at 285 records and had fallen to 62 by 2024, a 66% decline across that comparable window. Because publication typically lags filing by around 18 months, the most recent one to two years in any such dataset always look artificially low and should not be read as proof of a continuing drop. The safest read is that activity has cooled meaningfully from its 2017 high, based on the years that are essentially complete.
Polymer compositions (IPC class C08L) and condensation polymers (C08G) are the two most heavily claimed areas, covering 26.1% and 23.4% of the 4,842 records respectively. Additives (C08K) follow at 18.4%. Processing, shaping and layered-product classes are claimed less densely, which typically means less prior art to search around when drafting in those areas.
US9102792B2, assigned to Ticona and granted in 2015, covers a polymer composition combining at least one high-performance polymer with an aromatic amide oligomer that acts as a flow aid, lowering melt viscosity under shear. It is a composition-plus-additive claim rather than a base-polymer claim, so it constrains formulations that use this specific oligomer-as-flow-aid approach rather than high-performance polymer processing generally. Anyone working with amide-oligomer flow modifiers in a similar polymer matrix should review its claim scope directly before finalizing a formulation.
Relative to the dense composition classes (C08L, C08G, C08K), processing and forming classes such as B29C (shaping of plastics) and B32B (layered products) show proportionally lower claim density — 11.5% and 7.3% of records respectively. Enzyme-mediated self-healing and melt-flow modifier systems also show fewer claims relative to core composition filings. These are reasonable areas to search first before assuming the field is fully occupied.
