Viscosity Modifying Agents Patents: Who Leads, Where the Gaps Are 2026
Viscosity modifying agent patents for self compacting concrete
48.5% concentration at the top. The five leading assignees account for 228 of the 470 records in scope — filing here means competing directly with a small, entrenched group rather than a fragmented field. Filings rose from 5 in 2017 to a peak of 37 in 2021, then fell to 14 by 2024 — a 62% decline across that three-year span. Because publication lags filing by around 18 months, the 2025-2026 counts are still filling in and should not be read as a continuation of the decline.

Common questions about this landscape
What is a viscosity modifying admixture used for in self compacting concrete?
A viscosity modifying admixture (VMA) adjusts the rheology of fresh concrete so it flows readily enough to self-consolidate without vibration, while still resisting segregation of aggregate from paste. It works alongside superplasticisers to keep slump flow and passing ability within a target range, particularly when the water content or aggregate grading varies batch to batch. Welan gum is one of the most commonly referenced biopolymer-based VMAs in the patent literature, valued for stabilising mixes against bleeding and segregation.
Who are the leading patent filers in viscosity modifying agents for self compacting concrete?
Filing in this field is concentrated: the top five assignees together hold 228 of the 470 records in scope, or 48.5% of the total, and the leading single assignee alone holds 137 records against 18 for the fifth-ranked filer. That is a steep drop-off rather than a gradual one, meaning a small number of established construction-chemicals companies control most of the documented claim space. The ranking covers 100 companies in total, drawn directly from the dataset rather than a curated top-50 or top-100 list.
Is patent filing activity in this field growing or shrinking?
Filing volume peaked at 37 records in 2021 and had fallen to 14 by 2024, a 62% decline over that three-year window using the most recent year that can be treated as complete. Because patent publication typically lags actual filing by around 18 months, the lower counts recorded for 2025 and 2026 are still filling in and should not yet be read as evidence of continued decline. On the data available through 2024, however, the field’s most active filing period has passed.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Viscosity Modifying Agents for Self Compacting Concrete covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
