Compostable Film Quality Control Patent Snapshot 2026
The formal patent evidence snapshot for compostable film quality control is at its earliest possible stage, with a single patent family on record filed in 2026 by one academic institution in India. The field is effectively open: no established corporate block, no competing prior art, and broad adjacent technology branches that remain unaddressed.
One academic filer holds every family currently on record
Swami Vivekananda Subharti University is the sole ranked applicant, holding the single patent family in scope. Concentration is absolute at this scale: the top five filers’ share of the ranked applicants visible in this query stands at 100%, reflecting the absence of any competing corporate or institutional presence in the formal record.
There is no second-tier or challenger group to observe. The entire corpus is a single data point, which means no tier gap can be measured — the gap is the entirety of the field.

The leader’s position implies an unchallenged first-mover advantage for the filing institution, but it equally signals that industry has not yet chosen to protect innovations in this specific intersection of compostable materials and quality-control methodology.
The single family was filed in 2026 and is subject to normal publication lag; additional filings from the same or other applicants may not yet be visible in the corpus. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A field that emerged on record only in 2026, spanning packaging and materials-analysis branches
The annual filing trend shows zero activity from 2017 through 2025, with the single family appearing in 2026. The technology composition splits evenly across containers-and-packaging and material-analysis-and-testing branches.
Annual filing trend
No filings are recorded from 2017 to 2025; the sole family entered the corpus in 2026. Because 2026 is within the publication-lag window, the true volume for that year may be higher than currently visible.

The single family touches two IPC classes with equal weight: B65D (containers and packaging) and G01N (material analysis and testing). This dual classification suggests the invention bridges physical packaging form and analytical test methodology — a combination that is sparse across the broader patent record.

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.
Swami Vivekananda Subharti University
The university holds 1 patent family in scope, classified across B65D 65 (containers and packaging), G01N 21 (optical material analysis), and G01N 31 (chemical analysis). No momentum data is available given the single-year filing record; the 2026 entry represents a new entrant establishing a first position in the field. Protection is currently limited to India.
families: 1No challenger identified
No second applicant appears in the corpus. The challenger tier is vacant, meaning any organisation — academic, corporate, or governmental — that files in this technology space would immediately become the second-largest holder of record. The absence of a challenger is itself a meaningful signal of how early this field is.
families: 0Frequently asked questions
The current corpus contains 1 patent family in scope. This is an exceptionally small corpus, indicating the topic is either very new to formal IP protection or sits at a niche intersection that has not yet attracted broad filing activity.
Swami Vivekananda Subharti University is the sole applicant on record, holding the single patent family filed in 2026 and protected in India.
India is the only jurisdiction covered by the single family on record. No US, European, Chinese, or other national filings have been identified in the current corpus for this specific topic.
The single family is classified under B65D (containers and packaging) and G01N (material analysis and testing), specifically sub-classes covering optical analysis (G01N 21) and chemical analysis (G01N 31). These reflect the dual nature of the invention — packaging form combined with analytical quality-control method.
A formal lifecycle stage cannot be determined from a single data point. No filings were recorded from 2017 through 2025; the sole family appeared in 2026. The 2026 filing is within the standard publication-lag window, so additional families from that year may not yet be visible.
Given only one family exists, nearly all adjacent sub-branches are unaddressed. Particularly sparse areas include inline optical or spectroscopic testing during film manufacture (G01N 21 extensions) and standardised accelerated-composting degradation-rate protocols (G01N 31 extensions). Both have plausible commercial rationale tied to tightening compostability certification regulations globally.

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.
