Pipeline Integrity Monitoring Patents: Leaders & Trends 2026
- Filing accelerated sharply after 2022, climbing from 4 families at the midpoint to a peak of 53 in 2025 — the steepest run in this dataset's history.
- Measurement and vibration/sound IPC classes dominate, with G01D, G01N and G01H together outweighing the AI-specific G06N class by roughly 4 to 1, showing sensing hardware still outpaces analytics claims.
- The United States receives the majority of filings, 126 of 224 families, more than triple the WIPO/PCT count and six times India's, concentrating enforcement risk in one jurisdiction.
What this landscape covers
This landscape tracks patent families at the intersection of pipeline integrity monitoring — inspection, corrosion detection, encroachment sensing — and real-time condition monitoring techniques such as structural health monitoring and acoustic emission sensing. The 224 families captured span 2015 through the 2026 cut-off, with the most recent year necessarily undercounted because publication typically lags filing by around eighteen months.
The technology mix leans toward physical sensing and signal acquisition — general measurement, material testing, vibration and acoustic detection — rather than pure software analytics, though AI-based computing classes are present and growing from a small base.
Filing trends and technology composition
Two views of the same 224-family corpus: how filing volume has moved year over year, and which IPC subclasses carry the claim density.
Filing trend, 2017-2026
Filings held near single digits through the late 2010s, sat at 4 families at the 2022 midpoint, then rose steeply to a peak of 53 in 2025 before the partial, undercounted 2026 figure. That shape points to a technology that only recently became commercially urgent enough to justify sustained claim-building, rather than one in gradual, steady expansion.
IPC subclass composition
G01D (measuring and recording, 67 records) and G01N (material analysis and testing, 66) lead, closely trailed by G01H (vibration and sound measurement, 54) and G01M (structural testing, 41). Temperature sensing (G01K) and communications classes (H04B, H04L) form a supporting layer, while AI-based computing (G06N, 18 records) is present but still a minority claim area relative to the sensing hardware classes.
Shares are the percentage of the 224 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Method and apparatus for analysis and detection of encroachment and impact upon underground structures (US11609148B2)
A structural health monitoring system pairs a first set of sensors coupled to a buried structure, configured to detect impacts while underground, with a second set of sensors positioned at or near the surface to detect audible events at a distance. The system stores audio signatures that can be matched against detected events to identify encroachment or impact activity.Assignee: Acellent Technologies, Inc. · Published 2023-03-21

Citation counts favour older filings simply by virtue of longer exposure time; treat them as a measure of influence on later filers, not of present-day importance.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register.

Three signals stand out once the filing curve, technology mix and jurisdiction split are read together.
Growth is recent and steep
The move from 4 families at the 2022 midpoint to 53 in 2025 is not gradual drift — it is a step change concentrated in the last few years, consistent with condition-monitoring sensors becoming cheap and reliable enough for wide pipeline deployment.
Sensing hardware still leads analytics
Measurement, material testing and vibration/acoustic classes together account for far more filings than AI-based computing (G06N, 18). Claim space is still being built around how signals are captured, not only how they are interpreted.
Filing risk concentrates in the US
More than half of all families in this dataset were received by the United States, well ahead of WIPO/PCT (41), India (20) and Europe (15). Freedom-to-operate work should weight US prior art heavily before other jurisdictions.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to pipeline integrity monitoring condition monitoring, with the prior art for and against each one.
Who is filing and what is still open
Assignee activity in this corpus shows a small set of recent filers with modest year-on-year volume rather than one dominant incumbent, alongside a long tail of single- or few-filing entrants — a structure that still leaves room for new claims in adjacent sub-areas.
No single runaway leader
The most active assignee in the latest year filed only 2 families, with several others dropping to zero after prior activity. That is a fragmented field, not one locked up by an incumbent's claim thicket.
Wide participation, thin repeat filing
With 224 families spread across the full assignee ranking and most recent-year figures at zero or near-zero, repeat filing is rare. Most participants appear to file once or twice rather than build a sustained portfolio.
US filing is the practical gate
Any competitive assessment has to start with US-received filings, which outnumber the next four receiving offices combined. Entrants skipping US filing risk missing the office where most prior art and most future competitors will register.

Where to take this analysis
The filing curve and technology mix point to specific next steps for teams deciding where to file or partner.
Map claims against the sensing-hardware classes
With G01D, G01N and G01H carrying the bulk of filings, a freedom-to-operate review should start there rather than in AI/software classes, where claim density is still comparatively low.
Explore IPC breakdowns in Eureka →Watch US filings first
Because 126 of 224 families were received by the United States, competitive monitoring and clearance searches should treat US filings as the primary signal, with WIPO and India as secondary checks.
Run a jurisdiction search in Eureka →Track the post-2022 acceleration
The jump from single-digit to peak-year filing suggests new entrants are still arriving; a standing watch on recent publications will catch them before they mature into granted claims.
Set up a filing alert in Eureka →Common questions on pipeline integrity monitoring patents
This dataset captures 224 patent families published between 2015 and the 2026 cut-off that combine pipeline integrity or inspection terms with real-time condition monitoring, structural health monitoring or acoustic emission monitoring terms. Because publication typically lags filing by about eighteen months, the true count for the most recent year is understated. Family counts, rather than raw document counts, are used here because they neutralise duplicate continuation and multi-jurisdiction filings for the same invention.
No single assignee dominates this corpus; the most active filer in the latest year recorded only 2 families, and several previously active assignees dropped to zero year-on-year. That pattern indicates a fragmented competitive field with a long tail of entrants filing once or twice rather than building sustained portfolios. Anyone assessing competitive risk should look at the full assignee ranking rather than assume a clear incumbent leader.
General measurement and recording (G01D) and material analysis and testing (G01N) lead the IPC composition with 67 and 66 records respectively, followed closely by vibration and sound measurement (G01H) at 54. Structural testing (G01M) and temperature measurement (G01K) form a supporting tier, while AI-based computing (G06N) and digital transmission classes (H04B, H04L) are present but comparatively thin. This suggests claim space is still concentrated on sensing hardware and signal acquisition rather than purely on software analytics.
Comparatively thin IPC density around AI-based signal fusion, distributed fibre-optic strain sensing and cross-jurisdiction filing outside the US, WIPO and India suggests these are less claim-dense branches relative to the core measurement and acoustic-sensing classes. A first claim combining acoustic emission detection with an AI classification step for corrosion or encroachment, tied to a specific sensor placement, would sit in less-crowded territory than a pure hardware claim. Confirming this requires a targeted freedom-to-operate search against the specific sub-claims, not just the IPC-level counts shown here.
The United States receives the largest share of filings in this corpus at 126 of 224 families, more than three times the WIPO/PCT total of 41 and six times India's 20. Europe, Canada and Austria account for smaller shares. Competitive monitoring, clearance searches and enforcement strategy should treat US-received filings as the primary dataset, with PCT and India filings as secondary indicators of international intent.
