Geopolymer 3D Printing & Automation Patent Snapshot
The patent corpus for geopolymer 3D printing and automation is nascent, with only 2 families on record held by two separate academic and research institutions. The field is effectively open: concentration is absolute among the current filers, yet the minuscule absolute total signals a pre-assignee snapshot with substantial room for new entrants.
Two institutions define a near-empty field
Instituto Politécnico de Leiria and the Indian Institute of Science each hold 1 patent family, together accounting for all indexed activity in geopolymer 3D printing and automation. No corporate players appear in the current ranking.
The top five filers’ share of the ranked applicants visible in this query stands at 100%, but this figure reflects a corpus of just 2 patent families — concentration is technically absolute only because activity has barely started.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Instituto Politécnico de Leiria | 1 | |
| 2 | Indian Institute of Science | 1 |
The absence of large industrial assignees implies that the field has not yet attracted sustained corporate R&D investment; both leading positions are held by research institutions, suggesting the technology remains at an exploratory, proof-of-concept stage.
The most recent filing visible in the dataset (2025) is subject to standard publication lag and may undercount activity from the past 18–24 months; the true current corpus could be modestly larger than indexed. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sporadic filings and a core additive-manufacturing technology base
The annual filing trend and technology composition together characterise geopolymer 3D printing as an early-stage field with isolated activity spikes rather than sustained growth. The IPC class mix confirms that additive manufacturing is the defining technological framework, with adjacent materials and shaping classes in supporting roles.
Annual filing trend
Filings were zero from 2017 through 2021, with a single family appearing in 2022 and another in 2025; no year shows more than one filing. The 2025 data point is subject to publication lag and may not represent a trend. No multi-year growth trajectory can be inferred from two isolated data points.

B33Y (Additive manufacturing / 3D printing) is the only class present in both patent records, confirming it as the field’s technological anchor. B22F (Powder metallurgy), B28B (Shaping of clay and cement products), B29C (Shaping of plastics), and C04B (Ceramics, cement and refractories) each appear once, reflecting the materials-science breadth of geopolymer formulation work adjacent to the printing process.

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.
Instituto Politécnico de Leiria
Holds 1 patent family with technology emphasis on powder metallurgy process steps (B22F) and clay/cement product shaping (B28B), indicating a focus on the deposition and forming mechanics of geopolymer printing. Momentum is flagged as a new entrant, meaning the institution entered the indexed corpus for the first time in the recent period from a zero prior base.
families: 1Indian Institute of Science
Holds 1 patent family with emphasis on additive manufacturing output specifications (B33Y 80) and ceramics/cement chemistry (C04B 22, C04B 28), reflecting a materials-science approach centred on geopolymer binder composition and cured-product properties. No prior-period baseline is available for momentum comparison.
families: 1Frequently asked questions
The indexed corpus contains 2 patent families. This is an exceptionally small corpus, indicating the field is at a very early, pre-competitive stage.
Instituto Politécnico de Leiria and the Indian Institute of Science each hold 1 patent family. Both are academic or polytechnic research institutions; no commercial manufacturers appear in the current ranking.
Patent records have been filed in India and through the WIPO PCT system. No filings are indexed in the US, European, Chinese, or other major manufacturing jurisdictions based on the current evidence.
B33Y (Additive manufacturing / 3D printing) appears in both patent records and is the anchor class. B22F, B28B, B29C, and C04B each appear in one record, reflecting the materials-science and shaping-process dimensions of the technology.
No co-filed families or joint applicants are present in the dataset. Both active filers hold their families independently, and no collaboration activity has been detected in the indexed corpus.
A single filing appeared in 2022 and another in 2025; all other years between 2017 and 2026 show zero filings. Two isolated data points are insufficient to establish a growth trend. The 2025 filing is also subject to standard publication lag, so it may not yet be fully represented in search results.

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.
