CM-PATRACritical Minerals Patent and Technology Research Analytics
CM-PATRA / method
How CM-PATRA works, and what is measured
Software agents do the repetitive work; a person reviews exceptions. No language model sits in the publishing path, so the same input always gives the same output and every label can be traced.
Architecture
- Scout. Ingests Google Patents Public Data (BigQuery, CC BY 4.0) the SATYABHAMA ongoing-projects list and JNARDDC's ongoing and completed project lists, plus Indian Patent Office Journal issues (read by hand or ingested automatically).
- Classifier. CPC rules first, then title/abstract keyword rules, then reviewed overrides. Records the method on every label.
- Resolver. Merges applicant-name variants to one canonical organisation and tags country and type; keeps a project once when it appears on both the SATYABHAMA and JNARDDC lists.
- Auditor. Deterministic gate: identity present, id formats, date order. A failure blocks the build; odd source dates are flagged, not hidden.
- Analyst. Counts by mineral, stage, year and applicant; builds the technology-gap matrix against funded projects.
- Alerts. Fixed rules (empty minerals, funded-but-no-patent, recent Indian activity). Each alert states its rule.
Measured on this build (2026-10-16)
Coverage and provenance, computed from the data. Not classification accuracy: that needs a hand-labelled test set and has not been measured yet.
| Patent families kept / ingested | 371 / 606 | Classifier output vs scout input |
| Kept records with an English title | 58% | 215 of 371 |
| Kept records with a named applicant | 100% | 371 of 371 |
| Records with a specific mineral (not “general”) | 75% | Mineral resolved by CPC or text |
| Labels decided by CPC rules alone | 84% | Trace method = cpc-rules |
| Labels needing the text rules | 16% | Trace method = cpc-rules+text |
| Labels set by a reviewer override | 1 | Each carries its reason |
| Low-confidence records (no English text) | 30 | Flagged on the record page |
| Audit gate | Passed | 902 records checked |
| Journal publication to ingest (newest issue) | 0 day(s) | Issue 42/2026: published 2026-10-16, read 2026-10-16. A daily job checks for new issues. |
| R&D projects with a record-level candidate patent | 22 / 68 | Shared mineral plus a shared waste stream or two title words; by rule, not confirmed |
| Funded projects naming an India-list mineral | 68 / 296 | Title rules; SATYABHAMA ongoing list plus JNARDDC ongoing and completed lists |
Known-item check: does CM-PATRA find what it should?
5 Indian technologies named in public sources, each tested by a fixed rule. Found: 3 of 5. A miss is shown as a miss; five items measure recall on these items only, not overall recall.
| Item | Found | Rule |
|---|---|---|
| CSIR-IMMT and NALCO jointly patented process for coal fly ash (alumina and a rare-earth-enriched residue) (NALCO press release, 18 Aug 2026) | Not found | A kept patent family with both a CSIR and a NALCO applicant whose English text mentions fly ash. |
| CSIR-NML red mud technology recovering scandium, alumina, iron, TiO2 and a rare-earth concentrate (NALCO 10 t/day pilot) (SMM news, 9 Jan 2026 (agreement of 6 Jan 2026); does not say whether the process is patented) | Not found | A kept patent family with a CSIR applicant whose English text mentions red mud or bauxite residue together with scandium, rare earths or metal recovery. |
| CSIR process for recovery of gallium (Google Patents, CA-2480808-A1) | CA-2480808-A1 | A kept patent family with a CSIR applicant labelled gallium/germanium/indium. |
| JNARDDC 1000-litre Bayer liquor pilot plant for gallium recovery (S-58, Ministry of Mines) (JNARDDC Ongoing Projects page) | JNARDDC/S-58 | An R&D project whose title mentions gallium and Bayer liquor. |
| Red mud valorisation with scandium recovery (CSIR-AMPRI and JNARDDC, S&T Mines) (JNARDDC Projects Archive, S-38) | SNTMOM/108/2020 | An R&D project whose title mentions red mud and scandium. |
Classifier check on a random sample
40 kept patents were drawn at random. 15 of them have no English title in the source, so they could not be checked by reading and rest on classification codes alone. Of the 25 that could be checked, 21 had an acceptable mineral set (84%, 95% interval 65–94%). Random sample (seed 20261013) of 40 kept patents. Labels were assigned by the Claude build agent reading the title only; they are NOT independent of the classifier's author and NOT a domain-expert review. 'consistent' means the mineral set is acceptable given the title. This is a small, self-assessed sample: treat it as a smoke test, not as a precision claim.
- Process for Recovery of Battery Cathode Metal Oxides And Copper From The Wastes · lithium, nickel, copper · Cobalt is likely present in battery cathode oxides but was not labelled; incomplete.
- Process for manufacturing lower chlorides of titanium · titanium, aluminium · 'aluminium' added from CPC although the title is about titanium chlorides; over-inclusive.
- System and method for enhancing the efficiency of froth floation process for coal beneficiation · general · Coal beneficiation is not a mineral on the list; kept as 'general' but arguably out of scope.
- Green process for the preparation of pure iron · general · Pure iron labelled 'general'; should be iron-steel (not on India list, so no effect on in-scope counts).
Research papers beside patents and projects (OpenAlex, 2016-2025)
Papers with a mineral term and a processing term (extraction, recovery, leaching and similar) in the title or abstract, from the OpenAlex API on 2026-10-14. “India” means at least one author is affiliated with an Indian institution. This is a proxy for research activity, not a census: affiliation data is incomplete, a paper can count under several minerals, and broad words such as “processing” pull in materials-science papers. Patent families and funded projects are shown for comparison and are not merged into these counts.
| Mineral | India papers | World papers | India share | Patent families | Funded projects |
|---|---|---|---|---|---|
| Copper | 8,682 | 1,08,186 | 8.0% | 33 | 10 |
| Titanium | 5,994 | 66,995 | 8.9% | 22 | 4 |

| Niobium / Tantalum | 459 | 8,298 | 5.5% | 0 | 2 |
| Tin | 19 | 1,099 | 1.7% | 5 | 4 |
Tin is searched only as “tin ore”, cassiterite, “tin recovery” and “tin slag”, so its small count reflects a narrow query. Exact queries and request URLs are stored in data/patra/raw/openalex-2026-10-14.json. Source: OpenAlex (CC0).
Recent filings: Indian Patent Office Journal, issues 23/2026 to 42/2026
20 weekly journal(s), 2026-06-05 to 2026-10-16, list 41,572 newly published applications. A broad filter on classification and title words flagged 1151. Issues 41/2026, 40/2026, 39/2026, 38/2026, 37/2026 were read by hand; 15 issue(s) were ingested automatically, where a candidate is kept only if it carries an extraction, separation or recycling class (IPC C22B, C25C, B03, B09B, H01M10/54 or H01M6/52; 824 dropped on that rule) and its IPC class or title names a mineral in the ontology (87 dropped on that rule). 82 records are mineral-processing or recycling technology and 36 have an Indian applicant (name list or an Indian address). 17 further candidates were excluded with a written reason, mostly iron and steel making. Recall of the filter has not been measured, so these are a floor, not a census. The records are kept out of the main patent counts.

Limitations and risks
- Google Patents has few Indian-office filings for 2016–2026, so recent Indian filings are under-counted. Only 20 IPO Journal issues (23/2026 to 42/2026) are ingested; earlier issues are not.
- R&D coverage is two public lists (Ministry of Mines S&T projects on SATYABHAMA; JNARDDC projects) with titles, status and, for JNARDDC ongoing projects, sponsors. No outcomes, and other funders (ANRF, CSIR labs, DST) are not yet covered.
- Keyword and CPC rules can mislabel; overrides exist but the accuracy figure is not yet measured.
- Counts are lower bounds and are not legal advice or a freedom-to-operate opinion.
Roadmap to 30 October
- Ingest more IPO Patent Journal issues (one issue is piloted above).
- Research-paper outputs (OpenAlex): ingested, shown above. Next: link papers to the patent and project records.
- Hand-labelled test set and a measured accuracy figure.
- MCP tools so AI assistants can query the tracker.
- Watchlist alerts by mineral or applicant.
Cost to run: the dataset is a static file served with the site, so there is no per-query cost. Refreshing it from BigQuery costs per scan (the seed extract scanned about 258 GB per wide query).
