Patent Landscape · Updated 2026Recycling of Multilayer and Multi-Material Packaging: Patents, Leaders and Open Claim Space
- Concentrated at the top. The five leading assignees together hold 60.9% of all 276 records in scope, and the top ten hold 79.0% — this is a field with a narrow set of controlling filers, not a fragmented one.
- Filing activity has cooled. Filings peaked in 2018 at 7 in a year and have since flattened, with the 2022 midpoint back down to 1 — a pattern of early staking-out rather than sustained acceleration (the most recent year is always undercounted due to publication lag).
- Claims cluster around specific mechanisms. Layered products and laminates (B32B) and material analysis and testing (G01N) sit well behind the dominant medicinal-preparation and glass-composition classes, pointing to where multilayer-packaging-specific claim language is comparatively thin.

Overview
What this dataset covers
This landscape tracks patent activity at the intersection of layer separation and multi-material packaging recovery — filings that claim solvent-based or enzyme-mediated delamination, aluminum layer recovery, or sorting-detectability methods for multilayer structures. The search spans 276 published records filed between 2015 and the 2026 cut-off, ranked across 72 assignees. Because the underlying corpus draws on adjacent fields such as pharmaceutical glass and medical laminates, the technology composition below reflects cross-domain filing behaviour, not a packaging-only view.
Publication lags filing by roughly 18 months, so 2025 and 2026 figures in any trend line will look thinner than they eventually turn out to be. Read the concentration and composition figures as a snapshot of claim space already staked out, not a forecast of where filing is heading next.

The Numbers
Filing trends and technology composition
Two views of the same 276-record corpus: how filing volume has moved year over year, and which IPC subclasses carry the claims.
A peak in 2018, then a flat line
Filings rose to a peak of 7 in 2018, then declined toward a 2022 midpoint of just 1 — a growth curve that is flat or declining rather than accelerating. Treat the final one to two years as understated given publication lag, but the multi-year trend before that is not an artifact of lag.
Medicinal and glass classes dominate the composition
A61K (medicinal preparations) appears on 35.9% of the 276 records and C03C (glass and enamel compositions) on 31.2%, both ahead of B32B (layered products and laminates) at 11.6% — the subclass most directly tied to multilayer packaging structure. Because records can carry multiple IPC codes, these shares sum past 100% and should be read as overlap, not as a breakdown of the whole.
Shares are the percentage of the 276 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

A recent filing worth reading in full
Filed 2026-03-05 · BASF SE
Enzyme mediated delamination on demand of multilayer packaging materials (WO2026046755A1)
BASF SE
A laminate is described comprising at least two substrate layers of different materials bonded together by an adhesive layer comprising one or more enzymes capable of degrading polyester-polyurethanes. The laminate can be delaminated by contacting with a delamination liquid at delamination conditions.The claim structure ties delamination triggerability to the adhesive layer itself rather than to a separate treatment step, which is the detail worth checking against any adjacent filing before designing a competing laminate.

What the data means for filing strategy
Four read-outs from the concentration, trend and citation figures above.
Concentration
60.9% of 276 records
held by top 5 assignees
A narrow set of filers controls most of the claim space
With the five leading assignees together holding 60.9% of all 276 records and the top ten at 79.0%, new entrants are filing into territory already substantially claimed by a small group. This is not a fragmented field where a novel angle is easy to find by volume alone.
Top 10 = 218 of 276 records
Momentum
Peak year 2018 at 7
filings, since flattened
Early staking-out, not sustained growth
The filing trend rose to its peak in 2018 and has not returned to that level since, with the 2022 midpoint at just 1. Combined with publication lag understating the last one to two years, the honest read is a field that saw an early wave of claims rather than one still building.
2022 midpoint = 1 filing
Citation influence
241 citations
on the top-cited record
Older delamination-resistant glass filings anchor the citation graph
The most-cited records in this corpus are delamination-resistant pharmaceutical glass container filings, cited well above the rest of the set. That reflects their age and adjacency to a heavily cited disc-repair filing rather than current commercial weight in multilayer packaging specifically.
Citation counts favour older filings
Structure
10 co-assignee pairs
identified in the dataset
Collaboration is concentrated in a few recurring teams
Only 10 co-assignee pairs appear in the dataset, and the strongest three all involve the same three individuals filing together repeatedly at a co-occurrence of 21. That points to a small number of stable inventing teams rather than a broad collaborative network.
Strongest pairs co-occur at 21

Competitive Landscape
Who holds the claims, and where the gate sits
The ranking below covers all 72 assignees the data endpoint returns for this search — it is not a top-50 or top-100 cut, so absence from it means absence from the corpus, not a ranking cutoff.
Leader
93 records
held by the top assignee
One filer well ahead of the field
The leading assignee holds 93 of the 276 records in scope, more than seven times the fifth-place count of 13. That gap is unusually wide and suggests a single filer treating this as core claim territory rather than an opportunistic sideline.
Fifth place holds 13 records
Mid-tier
8 records
held by tenth place
A steep drop-off after the leaders
By tenth place, holdings fall to 8 records — a steep decline from the leader's 93. The top ten together still account for 79.0% of the 276 records, leaving comparatively little volume spread across the remaining 62 ranked assignees.
Top 10 = 218 of 276 records
Filing venues
87 filings
at the USPTO
US and EPO dominate receiving offices
The United States receives the largest share of filings at 87, with Europe (EPO) close behind at 70 and WIPO PCT filings at 28. Australia, China and Canada each sit in single-digit-to-low-teens territory, indicating this is primarily a US/EU prosecution story rather than a China-first one.

FAQ
Common questions about this landscape
One assignee leads with 93 of the 276 records in this dataset, well ahead of the fifth-place holder at 13 records. The top five assignees combined hold 60.9% of all records in scope, and the top ten hold 79.0%, so filing activity is concentrated in a small group rather than spread evenly across the 72 ranked assignees. Anyone assessing freedom to operate here should look closely at the leader's claim scope first, since it accounts for such a disproportionate share of the corpus.
Filing activity peaked in 2018 at 7 filings in that year and has not returned to that level since, with the 2022 midpoint sitting at just 1. That is a flat-to-declining trend rather than an accelerating one. The most recent one to two years will look artificially thin because publication typically lags filing by around 18 months, so treat 2025-2026 figures as provisional rather than as evidence the field has stopped.
By IPC subclass, medicinal preparations (A61K) appear on 35.9% of the 276 records and glass and enamel compositions (C03C) on 31.2%, both ahead of layered products and laminates (B32B) at 11.6%, which is the class most directly tied to multilayer packaging structure. Because a single record can carry several IPC codes, these percentages overlap and do not sum to 100%. The prominence of medicinal and glass classes reflects that this search pulls in adjacent pharmaceutical-packaging delamination work alongside packaging-specific filings.
WO2026046755A1, filed by BASF SE and published 2026-03-05, describes a laminate with substrate layers bonded by an adhesive layer containing enzymes that degrade polyester-polyurethanes, delaminated on demand by a delamination liquid under specified conditions. The claim ties triggerable delamination to the adhesive layer composition itself rather than to a separate post-processing step. Anyone designing a competing enzyme-triggered laminate should check whether their adhesive-layer chemistry and trigger mechanism fall inside this specific structure before proceeding.
Relative to the dominant medicinal-preparation and glass-composition classes, subclasses tied to sorting-detectability additives, solvent-free aluminum layer recovery, and multi-material curbside sortation show thinner representation in this corpus. That does not guarantee those areas are unclaimed elsewhere, but within this dataset's IPC composition they carry noticeably less density than the core classes. A first claim in these branches would need to specify the trigger mechanism or detection method precisely, since generic delamination-liquid claims are already well populated.
