Geopolymer Concrete Testing Patent Landscape 2026
The geopolymer concrete testing field has grown on a multi-year basis, with the top five filers holding a commanding share of activity among the hundred largest applicants, led by United States Gypsum Co and a cluster of Schlumberger entities. India is the dominant filing jurisdiction, and ceramics/cement chemistry accounts for the overwhelming majority of technology records, leaving adjacent branches such as standardised material analysis and additive manufacturing comparatively sparse.
United States Gypsum Co leads a moderately concentrated field anchored in cement chemistry
United States Gypsum Co ranks first with 68 patent families, followed closely by Schlumberger Technology BV at 66. The top five filers — United States Gypsum Co, Schlumberger Technology BV, Services Petroliers Schlumberger SA, Catholic University of America, and Entech Corp — together account for 37% of the combined output of the hundred largest applicants.
That 37% share is notable but not extreme, indicating a two-tier structure: a pair of dominant players (United States Gypsum Co and Schlumberger Technology BV are nearly level), a secondary tier of Schlumberger-affiliated entities and academic filers, and a long tail of smaller contributors. No single applicant holds an outright monopoly.

The co-presence of an oilfield-services cluster (multiple Schlumberger entities) and a building-materials leader (United States Gypsum Co) signals that geopolymer testing IP is being developed in parallel for well-cementing applications and for construction, creating two distinct but overlapping technology communities within one corpus.
The most recent filing years (2025–2026) are under-counted due to standard patent publication lag and should not be read as a plateau. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Multi-year growth with a 2023 peak; ceramics and cement chemistry dominate the technology mix
Annual filing volume and technology-class distribution together reveal a field that expanded strongly through 2023 and carries significant recent-window momentum, while the technology mix is heavily weighted toward core cement chemistry with scattered adjacent branches.
Annual filing trend
Filings rose from 22 in 2017 to a peak of 86 in 2023, reflecting a 42% uplift in the recent three-year window versus the prior three-year window. The 2024 and 2025 figures appear lower partly due to publication lag and should not be read as a structural decline. The field is still expanding on a multi-year basis, though annual volume has eased from its 2023 peak.

C04B (Ceramics, cement and refractories) is the dominant class by a wide margin, reflecting that most filings address binder chemistry and mixture formulation. C09K (Materials for miscellaneous applications, principally oilfield fluids) forms a secondary cluster driven by the Schlumberger entities, while E21B (earth and rock drilling), E01C (roads and pavements), and G01N (material analysis and testing) are present but at much lower counts, signalling under-served adjacent application spaces.

What the competitive structure means for R&D investment decisions
Four structural observations — maturity stage, concentration level, collaborative patterns, and geographic reach — frame the most consequential decisions for teams entering or expanding in this space.
Growth stage, past its 2023 peak on an annual basis but still expanding multi-year
The lifecycle assessment classifies this field as Growth: the recent three-year filing window sits 42% above the prior three-year window. Annual volume eased after the 2023 peak of 86 filings, but the multi-year trajectory remains positive. Teams entering now will encounter an active but not yet saturated competitive environment, with room to establish positions in adjacent sub-classes before consolidation sets in.
Growth stageModerate concentration with a dominant pair and a long academic tail
United States Gypsum Co and Schlumberger Technology BV are nearly level at the top, together with three other filers accounting for 37% of the top-hundred applicants’ combined output. Below this tier, activity disperses across academic institutions and small engineering firms, many filing single-digit family counts. This structure means the top pair can be monitored closely, but the long tail also contains differentiated niche approaches worth tracking.
Moderate concentrationCollaboration is dominated by intra-Schlumberger co-filing across affiliated entities
The most active co-filing pairs are all within the Schlumberger group: Schlumberger Technology BV with Services Petroliers Schlumberger SA (34 joint filings), each pairing with Schlumberger Canada Ltd (15 each), and Schlumberger Technology BV with Schlumberger Tech Corp (12). This pattern reflects coordinated IP portfolio management across legal entities rather than external partnership. No evidence of significant cross-industry or academic-industry co-filing is present in the top collaboration pairs.
Intra-group co-filingIndia leads filing activity, ahead of the United States and China
India is the top jurisdiction by patent records, followed by the United States and China, with Europe (EPO) and WIPO (PCT) providing additional international coverage. Australia and Canada also carry meaningful counts. The prominence of India — home to multiple academic and government filers in the ranking — suggests strong applied-research activity in construction and infrastructure testing. Teams seeking freedom-to-operate should prioritise India, the US, and China as primary clearance markets.

Co-filing pairs, ranked by the number of jointly-filed patent families.
United States Gypsum Co and Schlumberger Technology BV lead from distinct application angles
The two largest filers have near-identical family counts but serve different end markets — construction materials versus oilfield well cementing — creating parallel rather than directly competing patent portfolios.
United States Gypsum Co
The top-ranked filer with 68 patent families, focused on C04B 28 (cement binder formulations), C04B 12, and C04B 111 — all squarely within ceramics and refractories chemistry. Its portfolio is oriented toward construction-grade geopolymer performance and testing. Momentum data does not show a recent-window trend for this applicant, indicating its leadership position was built over a longer horizon rather than through a late surge.
families: 68Schlumberger Technology BV
The second-ranked filer with 66 patent families, and a new entrant in the recent filing window with 37 recent-period families — the strongest recent-window momentum of any tracked applicant. Its technology focus spans C04B 28, C09K 8 (oilfield fluid materials), and C04B 22, reflecting a deliberate strategy to deploy geopolymer chemistry in well-cementing and completion applications. Co-filed extensively with affiliated Schlumberger entities, amplifying its effective IP footprint.

Under-served branches in material testing, roads, and additive manufacturing
Several IPC classes appear at low counts relative to the dominant C04B core, suggesting areas where the existing corpus is sparse. These are observations of relative under-representation; whether each constitutes a genuine entry opportunity depends on technical fit and commercial context.
G01N · Material analysis and testing
With only 11 patent records against a corpus anchored in formulation chemistry, standardised physical and chemical testing protocols for geopolymer concrete are conspicuously under-represented. Given increasing regulatory interest in performance-based standards for low-carbon construction materials, filers focused on characterisation methods, durability testing, or in-situ monitoring could occupy a technically valuable and currently sparse sub-space. Entry could leverage existing laboratory-testing or sensing IP.
Search this in Eureka →B33Y · Additive manufacturing (3D printing)
Only 9 patent records sit in the B33Y class, indicating that the intersection of geopolymer binder systems and 3D-printed concrete testing is largely unexplored in the patent record. As additive manufacturing of cement-based structures scales up, testing protocols for layer adhesion, curing kinetics, and structural integrity of printed geopolymer parts represent an adjacent technical challenge with growing commercial relevance. Teams with concrete-printing process IP may find this a natural extension.

Frequently asked questions
The corpus contains 513 patent families in scope, spanning all major filing jurisdictions globally.
United States Gypsum Co leads with 68 patent families, narrowly ahead of Schlumberger Technology BV at 66 patent families.
India is the leading jurisdiction by patent record count, followed by the United States and China. The high Indian count reflects activity from academic institutions and government research bodies such as CSIR and multiple engineering colleges.
The field is classified as Growth: the recent three-year filing window is 42% above the prior three-year window on a multi-year basis. Annual volume peaked in 2023 and has eased since, and the most recent years are further understated by publication lag, so no structural decline should be inferred.
C04B (Ceramics, cement and refractories) is by far the largest class, reflecting emphasis on binder formulation, mixture chemistry, and material composition. C09K (oilfield fluid materials) forms a secondary cluster driven by Schlumberger-affiliated filers targeting well-cementing applications.
G01N (material analysis and testing) and B33Y (additive manufacturing) each have low record counts relative to the core, suggesting that standardised testing protocols and 3D-printed geopolymer concrete testing are comparatively sparse areas. E01C (roads and pavements) and B28C (mortar and concrete mixing) are similarly under-represented in the corpus.
