Geopolymer Low-Cost Precursor/Activator Patent Snapshot
The geopolymer low-cost precursor/activator space is a nascent, fragmented field: 16 patent families are distributed across academic institutions, engineering firms, and one clear commercial leader — Sika Technology AG. The field is still expanding on a multi-year basis, with recent-window growth well above the prior period, though annual volume has eased from its 2018 peak and the most recent years are further understated by publication lag.
Sika leads a fragmented field dominated by Indian and academic filers
Sika Technology AG holds the top position among all applicants, followed by Thiagarajar College of Engineering and the University of South Carolina, each with two patent families. The field is spread thin: fourteen distinct applicants share 16 patent families, with no single player commanding a commanding share.
The top five filers account for half of the combined output of the ranked applicants visible in this query — a moderate concentration level for so small a corpus, indicating that no single entity has established deep portfolio dominance. The gap between the leader (three patent families) and the rest of the field is narrow, leaving the visible assignee structure highly contestable.

Sika’s position as the sole established commercial materials company among the top filers signals early-stage commercial interest, while the prominence of Indian academic institutions and individual inventor applicants reflects the field’s pre-commercial research character. Entry by additional industry players could rapidly reshape the ranking.
Filings from the most recent 18–24 months are subject to publication lag and are likely under-counted; the apparent concentration of recent activity should be interpreted with that caveat. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Multi-year growth is positive, with ceramics/cement class dominating the technology mix
Two charts below capture the pace of filing activity over time and the IPC class distribution across the corpus — together they reveal both the field’s growth trajectory and its near-total concentration in a single technical domain.
Annual filing trend
Annual filings were sparse and irregular from 2017 through 2023, with a pronounced cluster appearing in 2025. The three-year recent window sits 200% above the prior three-year window, confirming multi-year growth — though 2025 and 2026 figures are likely understated due to publication lag, and the early 2018 activity represents a prior local peak. Do not read the 2025–2026 counts as a definitive plateau or peak.

C04B (Ceramics, cement and refractories) accounts for all 16 patent families in the corpus, confirming that virtually all IP activity is anchored in cementitious binder formulation. C02F (water and wastewater treatment) and C09D (coatings, paints and inks) each appear once, marking them as adjacent but sparsely covered branches.

Fly ash-based geopolymer binders and activating solutions for use in forming a concrete as well as methods for forming concrete including the binders are described. The fly ash-based geopolymer binders include a combination of fly ash, silica fume, and sodium hydroxide as well as an amount of Portland cement.

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.
Sika Technology AG
Sika Technology AG holds three patent families — the largest single portfolio in the corpus — concentrated entirely within C04B sub-classes covering ceramics, cement and refractories (C04B 18, C04B 22, and C04B 28). Their applicant momentum is flagged as a new entrant, indicating recent entry into this specific space. Sika’s co-filing with Kobe Steel suggests an interest in industrial-scale formulation collaboration.
families: 3Thiagarajar College of Engineering
Thiagarajar College of Engineering holds two patent families, with technical focus spanning C04B 12, C04B 28, and a single record in C02F 1 (water treatment) — the only top-tier applicant with documented presence outside pure cementitious chemistry. This cross-domain footprint is notable given the otherwise uniform C04B concentration across the field.
families: 2Frequently asked questions
The corpus contains 16 patent families in scope, distributed across 14 distinct applicants including commercial firms, academic institutions, and individual inventors.
Sika Technology AG holds the largest portfolio with three patent families, making it the top-ranked applicant. Thiagarajar College of Engineering and the University of South Carolina each hold two patent families.
India leads all filing jurisdictions with nine patent records, followed by China and the United States with two each. The UAE, Europe (EPO), and WIPO (PCT) each account for one record, indicating limited international protection coverage so far.
The field is assessed as Growth stage: the recent three-year filing window is substantially above the prior three-year window (200% growth), though annual volume has eased from the 2018 peak and recent filings are likely under-counted due to publication lag.
Two co-filing pairs have been identified. Sika Technology AG and Kobe Steel Ltd. have jointly filed one family, representing the only industry-to-industry collaboration in the corpus. China Railway Tunnel Group and China Railway Tunnel Survey and Design Research Institute have also co-filed one family.
C02F (water and wastewater treatment) and C09D (coatings, paints and inks) each account for only one patent record apiece, making them the sparsest adjacent branches. Both have plausible technical connections to geopolymer chemistry but remain essentially unclaimed relative to the visible C04B domain.
