Compostable Shelf-Life vs Compostability Patent Snapshot
This is a nascent, lightly contested field — just 30 patent families in scope — with Procter & Gamble leading a fragmented group of academic institutions and small innovators concentrated in India. Activity accelerated sharply from 2022 onward, and polymer-composition chemistry dominates the technical mix, leaving adjacent branches in additives, laminates, and food-packaging applications relatively sparse.
A nascent field led by Procter & Gamble, with activity dominated by Indian filers
Procter & Gamble is the single largest filer, holding 5 patent records, followed by a cluster of applicants — KG Ecoplast, Velammal Engineering College, DOST–Philippine Science High School System, and Global Patented Tech — each with 2 patent records.
The top five filers account for 20% of the combined total across the ranked applicants visible in this query, indicating low concentration overall. The field is populated mainly by academic institutions and small commercial entities rather than large incumbent material or packaging companies.

Procter & Gamble’s lead, focused on polymer compositions, suggests the tension between preserving product shelf life and ensuring end-of-life compostability is being addressed primarily through formulation chemistry. The absence of other major consumer-goods or packaging multinationals from the ranking is notable and points to significant open territory.
Filing activity in the most recent 18–24 months is subject to publication lag and likely understates true activity; conclusions about recent momentum should be treated as provisional. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Rapid acceleration since 2022, anchored in polymer-composition and packaging classes
The filing trend and technology composition together describe an early-stage field that activated in 2022 and built quickly, with its technical core sitting in polymer formulation and container design.
Annual filing trend
No filings appear before 2022; activity jumped to 2 records in that year, rose to 3 in 2023, and reached 9 in both 2024 and 2025, with 7 recorded so far in 2026. The 2025 and 2026 figures are subject to publication lag and almost certainly undercount actual activity — the apparent plateau should not be read as a real slowdown.

Polymer compositions (C08L) is the visible IPC class, followed by containers and packaging (B65D) and polymer processing (C08J). Use of additives in polymers (C08K), layered products (B32B), and food and beverage applications (A23L) each register materially lower counts, marking them as the most under-served adjacent branches in the current corpus.

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.
Procter & Gamble
Procter & Gamble holds 5 patent records — the largest share among all applicants — concentrated in polymer compositions (C08L 101 and C08L 67). This formulation-level focus reflects an effort to engineer compostability directly into material chemistry rather than through structural packaging design. No momentum data is available in the evidence base, so trajectory cannot be characterized.
5 patent recordsKG Ecoplast
KG Ecoplast holds 2 patent records and is a new entrant according to filing momentum data. Its technical emphasis spans containers and packaging (B65D 65) and polymer compositions (C08L 101 and C08L 23), positioning it at the intersection of material formulation and packaging format — a combination that could support broader commercial applications than formulation alone.
2 patent recordsFrequently asked questions
The corpus in scope contains 30 patent families. This is a small, early-stage corpus; the field only began generating filings in 2022.
Procter & Gamble is the leading filer with 5 patent records, focused on polymer compositions. No other single applicant holds more than 2 patent records.
India is by far the most active filing jurisdiction, accounting for 24 of the patent records in scope. WIPO (PCT) is the only other jurisdiction with more than one filing.
Polymer compositions (C08L), containers and packaging (B65D), and polymer processing and solutions (C08J) are the three leading classes. Use of additives (C08K) and layered products (B32B) are materially less represented.
Only one co-applicant relationship is recorded in the evidence: a single joint filing between Fascio Carlo and Global Patented Tech. The field is otherwise characterized by independent filing activity.
Filings rose from 2 records in 2022 to 9 in both 2024 and 2025. The 2025 and 2026 figures are subject to publication lag, so the apparent plateau in recent years should not be interpreted as a slowdown; true recent activity is likely higher than the recorded figures show.
