Compostability Testing (EN 13432) Patent Snapshot 2026
The patent corpus for compostability testing aligned with EN 13432 is currently minimal, comprising just 2 patent families, all held by a single applicant, KG Ecoplast Pte Ltd, filed in India in 2024. The field is effectively uncontested, presenting an open evidence snapshot for organisations seeking to establish IP positions in compostable packaging and polymer compliance testing.
KG Ecoplast holds the entirety of a nascent, single-applicant field
The ranked applicant list contains only one entity: KG Ecoplast Pte Ltd, holding all 2 patent families in scope. Concentration is absolute — no second-tier filer exists in this corpus.
With the top five filers’ share of the ranked applicants visible in this query at 100%, there is no observable tier gap because there is effectively no competitive field to stratify. The corpus represents a single organisation’s earliest IP moves rather than an established competitive market.
| # | Applicant | Patent families | Share |

KG Ecoplast’s position implies first-mover status in a very early-stage area. However, the absence of any other filers and the lack of cited prior art suggest that formal patent activity around EN 13432 compostability testing is either nascent or that practitioners have historically relied on trade secrets, regulatory compliance documents, or standards bodies rather than patents.
Note that filings from the most recent 18–24 months are typically under-counted due to publication lag; the 2024 entries may therefore understate actual recent activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
All activity concentrated in 2024 across two IPC branches
The annual filing trend shows zero activity from 2017 through 2023, with 2 patent families appearing in 2024 — the sole year of recorded activity. The technology composition is split evenly between packaging containers (B65D) and polymer compositions (C08L).
Annual filing trend
All recorded activity falls in 2024, with no filings detected in prior years or in 2025–2026. Because the 2024 entries are within the publication-lag window, it is premature to treat this as the definitive peak; additional filings may surface as applications publish.

The two IPC classes present — B65D (containers and packaging) and C08L (polymer compositions) — reflect the dual technical focus of compostability testing: physical packaging form and underlying polymer material behaviour under composting conditions. Neither branch is visible in; both carry equal weight in this corpus.

A method for preparing biodegradable packaging bag…
The present invention relates to a method for preparing biodegradable packaging bags from thermoplastic starch and composition thereof. The invention relates to preparation of an eco-friendly biodegradable film composition comprising 50-70 wt.% thermoplastic starch, 10-30 wt.% LDPE, and 10-20 wt.% EVOH copolymer. The thermoplastic starch is prepared by… (excerpt from the patent abstract)

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.
KG Ecoplast Pte Ltd
KG Ecoplast Pte Ltd holds all 2 patent families in this corpus, classified under both B65D 65 (containers and packaging) and C08L 101 / C08L 23 (polymer compositions). The applicant entered in 2024 with no prior filing history in this corpus, marked as a new entrant. Their dual-branch coverage suggests an integrated approach spanning material formulation and packaging application.
families: 2No challenger on record
No second applicant appears in the ranked corpus. The challenger position is vacant, meaning any organisation filing in this space now would immediately establish itself as the field’s second IP holder. Evidence for this position is pending until additional filings publish.

The current corpus contains 2 patent families in scope, both filed by KG Ecoplast Pte Ltd in India in 2024. This is a very small corpus and should be interpreted as an early snapshot rather than a mature field count.
KG Ecoplast Pte Ltd is the sole and therefore leading filer, holding all 2 patent families in the ranked corpus. No other applicant appears in the evidence.
The two IPC classes present are B65D (containers and packaging) and C08L (polymer compositions), each appearing in 2 patent families. Adjacent classes relevant to EN 13432 testing — such as C12Q for microbial assays and G01N for analytical methods — show no recorded filings in this corpus.
India is the only jurisdiction with recorded filings, accounting for both patent families in scope. No filings in the EU, US, China, or via PCT are present in the current evidence.
Filing activity was zero from 2017 through 2023, with 2 patent families appearing in 2024. No further filings appear in 2025 or 2026 in the current evidence, though filings from the past 18–24 months are typically under-counted due to publication lag. A meaningful growth trend cannot be established from the current data.
No co-applicant relationships are recorded in the corpus. All filings are attributed solely to KG Ecoplast Pte Ltd. The small corpus size means the absence of collaboration evidence is not conclusive for the broader field.

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.
