RO Membrane Material Supply Patent Snapshot 2026
The patent corpus for RO membrane material supply is currently represented by a single family, filed by the Council of Scientific & Industrial Research in India in 2023, indicating that this is an early-stage or narrowly scoped search space with minimal documented activity. The assignee snapshot is effectively pre-competitive, with no multi-party rivalry evident from the available evidence.
Council of Scientific & Industrial Research holds sole documented position
The applicant ranking contains one entry: the Council of Scientific & Industrial Research, which accounts for all 1 patent family in scope. This represents a maximally concentrated evidence snapshot by any measure.
With only one filer visible, there is no tier gap to characterize — the top five filers’ share of the ranked applicants visible in this query stands at 100%, reflecting the absence of any competing applicants in the current corpus.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | COUNCIL OF SCI & IND RES | 1 |
The sole applicant’s position implies either a very early-stage technology area, a narrowly defined search query, or both — making this corpus a starting signal rather than a mature competitive map.
Only one patent family appears in the data; results from 2024 onward should be treated as potentially undercounted due to standard patent publication lag of 18–24 months. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2023 filing defines the visible activity window
The annual filing trend shows no activity from 2017 through 2022, a single filing in 2023, and no recorded activity thereafter. The technology composition spans three IPC branches, reflecting the multidisciplinary nature of even this single family.
Annual filing trend
All visible activity is concentrated in 2023; years from 2024 onward are subject to publication lag and should not be read as confirmed zero activity. The pre-2023 absence may indicate the search scope is narrowly defined or that earlier work was filed under different classifications.

The present invention relates to an integrated membrane and resin system for the production of ultrapure methanol for pharmaceutical and electronic-grade applications. The process aids in the purification of laboratory-grade methanol using an indigenously developed Nanofiltration (NF; close to reverse osmosis) membrane and treating the product with Indion… (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.
Council of Scientific & Industrial Research
The Council of Scientific & Industrial Research (India) holds the single patent family in scope, filed in 2023, marking it as a new entrant in this defined search space. Its technical emphasis falls across B01D 61, B01D 67, and B01D 69 — all sub-branches of membrane separation processes — indicating focus on membrane fabrication and module design rather than upstream raw material chemistry alone.
patent families: 1No challenger identified
No second applicant appears in the corpus. A challenger profile cannot be constructed from the available evidence. Competitive entrants in RO membrane material supply IP are not yet visible in this dataset.
patent families: —Frequently asked questions
The current corpus contains 1 patent family, filed by the Council of Scientific & Industrial Research and recorded in India.
The Council of Scientific & Industrial Research is the sole and therefore leading applicant in the corpus, with 1 patent family filed in 2023.
India is the only jurisdiction of record in the current dataset, with 1 patent record filed there. No PCT or other national-phase entries are visible in the evidence.
The single family spans three IPC branches: B01D (separation processes including filtration), B82Y (nanotechnology applications), and C07C (acyclic and carbocyclic compounds), reflecting a multidisciplinary, nano-enhanced membrane chemistry approach.
No filings are recorded from 2017 through 2022. A single family appears in 2023. The years 2024 onward show zero recorded activity, but this should be treated with caution given the standard 18–24 month patent publication lag.
No co-applicant or collaborative filings are present in the current corpus. The collaboration dataset is empty, consistent with a corpus of one patent family from a single institution.

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. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
