Nano-Additive Geopolymer Patent Snapshot 2026
Nano-additive geopolymer patenting is in a confirmed growth phase, with India and China leading filing activity and academia dominating the applicant roster. The field remains fragmented, with the top five filers accounting for only 23% of the hundred largest filers’ combined total, leaving substantial space for new entrants.
Academic institutions lead a fragmented, early-stage field
Zhejiang University holds the leading position with 4 patent records, followed by Tirupathi Venu Madhav and Saudi Arabian Oil Company, each with 2 patent records. The applicant roster mixes Chinese universities, Indian independent inventors, and one major oil-and-gas company, reflecting the technology’s cross-sector relevance.
The top five filers account for 23% of the ranked applicants visible in this query’ combined total, indicating a genuinely fragmented visible assignee structure with no single visible force. The gap between the leader and the second tier is narrow — only 2 patent records — which means the ranking is easily disrupted by a single new filing campaign.

The academic dominance signals that commercialization pathways remain open. Industrial players such as Saudi Arabian Oil Company and Aramco Services Company are present but individually hold small positions, suggesting that corporate entry at scale has not yet occurred.
Filings from the most recent 18–24 months are likely under-counted due to standard patent publication lag and should be interpreted cautiously. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filings are rising and overwhelmingly concentrated in ceramics and cement chemistry
Two signals define the field’s current structure: an upward filing trend across the recent multi-year window, and a technology mix dominated by a single IPC branch, with four adjacent branches each holding only marginal shares.
Annual filing trend
Annual filings grew 60% in the recent window, with 2024 and 2025 each reaching 4 filings and 2026 already at 3 — though those two years are likely under-counted due to publication lag. The 2020–2021 trough appears to be a temporary dip rather than a structural shift. The overall multi-year trajectory remains upward.

C04B (Ceramics, cement and refractories) accounts for 26 patent records, establishing it as the field’s core branch by a wide margin. C01B (Non-metallic elements and inorganic compounds) and C09K (Materials for miscellaneous applications) each hold 2 records. E01C (Roads and pavements) and G01N (Material analysis and testing) each hold 1 record, marking them as sparse adjacent areas.

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.
Zhejiang University
Zhejiang University holds 4 patent records, the largest position in the field. Its filings concentrate on C04B 28 (hydraulic binders and geopolymer matrix chemistry) and C04B 12 (alumino-silicate systems), reflecting a focused research agenda on the fundamental cementitious reaction. No momentum data places it among recent new entrants, suggesting its position was built over multiple filing cycles.
4 patent recordsShenzhen University
Shenzhen University enters as a new entrant with 2 patent records and a notably broader technology footprint, spanning C01B 33 (silica and silicon compounds), C04B 14 (mineral aggregates), and C04B 18 (industrial by-products as raw materials). This multi-branch approach suggests an interest in nano-silica sourcing and aggregate engineering alongside binder chemistry — a differentiated angle relative to the field leader.
2 patent recordsFrequently asked questions
The corpus contains 24 patent families in scope. This is a relatively small corpus, reflecting the field’s early-growth status rather than a mature technology domain.
Zhejiang University leads with 4 patent records, followed by Tirupathi Venu Madhav and Saudi Arabian Oil Company, each with 2 patent records. The ranking is narrow and could shift with a single focused filing campaign by any second-tier applicant.
India leads with 9 patent records, followed closely by China with 8. The United States follows with 4 records. Australia, Germany, South Korea, Bulgaria, and WIPO (PCT) each account for 1 record, indicating that broad international protection has not yet been pursued by most applicants.
The field is in a Growth stage. Annual filings increased 60% in the recent window. The most recent years (2025–2026) are likely under-counted due to publication lag, so the true pace of growth may be faster than the raw trend data suggests.
C04B (Ceramics, cement and refractories) accounts for 26 patent records, far exceeding all other IPC branches. This reflects the field’s core focus on geopolymer binder and matrix chemistry. Adjacent branches such as E01C (Roads and pavements) and G01N (Material analysis and testing) each hold only 1 record.
Three co-filing pairs are identified: Saudi Arabian Oil Company with Aramco Services Company; Guangxi University with Guangxi Dapu Highway Company; and Jiangxi Tenda Electric Power Design Institute with State Grid Jiangxi Economic and Technical Research Institute. Each pair reflects a specific applied sector — oil well cementing, road infrastructure, and power grid infrastructure respectively.
