UHPC Facade & Envelope Patent Snapshot 2026
The UHPC facade and envelope patent space is small and highly concentrated, with Roman Cement LLC holding the largest single-applicant position among a corpus of 13 patent families. The field is in a multi-year growth phase, though annual volume has eased from its 2018 peak and recent years remain understated by publication lag.
Roman Cement LLC leads a tightly held, nascent space
Roman Cement LLC ranks first in patent records among all applicants in scope, followed by TAKTL LLC in second place. The top five filers together account for 63% of the ranked applicants visible in this query’ combined total, signalling a highly concentrated visible assignee structure with limited mid-tier presence.
The gap between the leader and the rest of the field is pronounced: Roman Cement LLC holds 5 patent records while nine of the eleven ranked applicants each hold a single record. This near-absence of a challenger tier suggests the space has not yet attracted broad institutional investment.

Roman Cement LLC’s position reflects a sustained, formulation-level IP strategy anchored in cementitious composition patents. TAKTL LLC, the nearest challenger, is a new entrant whose recent activity signals emerging commercial intent. The thin ranks below these two leave substantial room for well-targeted entrants.
The most recent 18–24 months of filings are subject to publication lag and will appear understated until records are published; conclusions on very recent momentum should be treated accordingly. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2018 activity spike, a quiet mid-period, and renewed recent filings
The annual filing trend and technology composition together reveal a field that burst briefly in 2018, contracted sharply, and is now registering renewed activity — while cementitious composition work remains the visible technical branch.
Annual filing trend
A spike to 4 records in 2018 was followed by two years of zero activity, then a gradual recovery reaching 3 records in 2024. The most recent years (2025–2026) carry publication lag and should not be read as indicative of the true current pace. On a multi-year basis the field is still expanding relative to its prior three-year window, consistent with the growth lifecycle stage.

C04B (ceramics, cement and refractories) is visible in with 9 records, reflecting the formulation-intensive nature of UHPC. B28B (shaping clay and cement products) and E04F (building finishing) are the next most active branches. Lower-count branches — including E04B, B28C, and several outliers — point to adjacencies that remain lightly explored.

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.
Roman Cement LLC
Roman Cement LLC holds 5 patent records — the largest position in the corpus — concentrated in C04B subclasses covering cementitious binders, aggregate composition, and concrete mixing (B28C). The most-cited records in the corpus are Roman Cement’s white cementitious composition patents, one of which carries 20 citations. No momentum signal is required here: the applicant predates the recent-entrant window and established its position primarily around the 2018 peak.
5 patent recordsTAKTL LLC
TAKTL LLC holds 2 patent records and is classified as a new entrant in the recent filing window, signalling that its IP activity falls entirely within the most recent period. Its technical focus spans C04B subclasses covering aggregate, binder, and admixture chemistry — overlapping directly with Roman Cement LLC’s visible branch, which will create claim-proximity considerations for both parties.
2 patent recordsFrequently asked questions
The corpus in scope contains 13 patent families. This is a small corpus, consistent with an early-growth field where commercial deployment is ahead of broad IP activity.
Roman Cement LLC is the leading filer with 5 patent records, more than double the next-ranked applicant, TAKTL LLC, which holds 2 records. All other ranked applicants hold a single record each.
The evidence places the field in a Growth stage: the recent three-year filing window is well above the prior three-year window. Annual volume has eased from its 2018 peak, and the most recent years are understated by publication lag, so the true current pace is likely higher than the raw counts suggest.
China and the United States each have 5 and 4 records respectively, followed by Canada with 3 and India with 1. European and other Asia-Pacific jurisdictions are not represented in the current corpus.
C04B (ceramics, cement and refractories) is the visible branch with 9 records, reflecting the formulation-intensive nature of UHPC. B28B (shaping clay and cement products) and E04F (building finishing) are secondary branches. Structural integration and mixing-process branches remain sparsely populated.
Only one co-applicant relationship is recorded: Shanghai Dijiang Building Technology Co. and Shanghai Dijiang Group, which appears to be a parent-affiliate pairing. No cross-sector or university-industry co-filings are evident, suggesting the ecosystem has not yet formed research partnerships despite two universities holding individual records.

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.
