Pipeline Coatings Patents: Who Leads, Where the Gaps Are 2026
Pipeline Coatings and Cathodic Protection Patents
Ownership is concentrated fast: the top 5 assignees alone account for 51.1% of all 661 records in scope, and the top 10 reach 64.0%. Filings peaked at 48 in 2017 and declined through the early 2020s before recovering: 2021 to 2024 moved from 5 to 11 filings, a +120% increase across that span. 2025 and 2026 figures are still incomplete because publication typically lags filing by around 18 months, so the most recent two years understate real activity rather than signalling a slowdown.

Common questions about this landscape
Who holds the most patents in pipeline coating and cathodic protection technology?
One assignee leads the ranked list with 155 records, more than double the fifth-place holder’s 22. The top 5 assignees combined account for 51.1% of all 661 records in scope, and the top 10 reach 64.0%. Below that group, the remaining assignees in the 98-company ranking each hold comparatively small counts, so most freedom-to-operate risk outside the leader concentrates in a mid-tier of firms rather than a single competitor.
Is patent filing in this field growing or shrinking?
Filings peaked at 48 in 2017 and declined for several years before recovering: 2021 to 2024 moved from 5 to 11 records, a +120% increase. Because patent publication typically lags filing by around 18 months, the 2025 and 2026 counts in any dataset pulled today are still incomplete and should not be read as a renewed slowdown. The safest complete-year comparison currently available is the 2021-2024 span.
What technology areas dominate pipeline coating patent claims?
F16L (pipes and pipe fittings) appears in 52.5% of the 661 records, making it the most common claim class by a wide margin. B29C (shaping of plastics) follows at 31.2%, reflecting how coatings are applied and formed, while C23F (corrosion and metal removal) sits at 13.3% and C09D (coatings, paints and inks) at 8.8%. Because records can carry multiple IPC classes, these figures overlap rather than summing to 100%, showing that coating and pipe-fitting claims are frequently drafted together.
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 Pipeline Coatings and Cathodic Protection 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.
