Patent Landscape · Oil, Gas, Coal & RefiningMethane Detection & Mitigation Patents: Who Leads and Where Filing Is Headed
- Concentrated at the top. The five most active filers account for 91 of 347 records in scope (26.2%), with the leader alone holding 25.
- Filing kept climbing through 2024. Filings rose from 28 in 2021 to 38 in 2024, a 36% increase, with a peak of 40 in 2022 — 2025 and 2026 figures are still filling in due to publication lag.
- Optical and laser sensing dominates the claim map. G01N material analysis and testing appears in 58.8% of records, more than double the next largest class, G01M testing/structure balance at 27.1%.

Filing growth compares 2021 (28 records) with 2024 (38) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 347 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
This landscape tracks 347 published patent records filed against methane leak detection and mitigation technology between 2015 and mid-2026, spanning optical and laser sensing, drone- and satellite-based scanning, wellbore and pipeline integrity monitoring, and the data pipelines used to quantify and report emissions. The search combines detection-method language with equipment-integrity and process-condition terms, so it captures both the sensing hardware and the operational contexts — wellbore systems, reservoir fluid handling, material degradation — where that hardware gets deployed.
Filing activity sits mostly with oilfield services and specialist sensing firms rather than diversified conglomerates, and the technology composition points to optical/spectroscopic detection as the dominant claim strategy, with pipeline transport and navigation/positioning classes appearing as secondary, connective technology rather than standalone cores.

The Data
Filing trend and technology composition
Two views of the same 347 records: how filing volume has moved year over year, and which IPC subclasses carry the claim weight. Because a single record can carry several IPC codes, the composition shares sum to well over 100% of the record total.
Filing trend, 2017–2026
Annual filings rose from 26 in 2017 to a peak of 40 in 2022, then eased to 38 in 2024 — still up 36% on 2021's 28. Treat 2025 and 2026 as undercounts: publication typically lags filing by around 18 months, so the most recent years will fill in as more records publish.
IPC subclass composition (share of 347 records)
G01N (material analysis and testing) touches 58.8% of records, reflecting the dominance of spectroscopic and sensor-based detection claims. G01M (testing/structure balance) at 27.1% and G01J (radiation and light measurement) at 14.4% follow, with E21B (wellbore drilling), H04N (pictorial communication), G06Q (data processing), G01C (navigation) and F17D (pipeline transport) each present in roughly 6-10% of records as supporting technology rather than the primary claim focus.
Shares are the percentage of the 347 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Algorithmic mission generation and interpretation for a drone-mounted methane detector
SCHLUMBERGER TECHNOLOGY CORPORATION
Systems and methods are described herein for methane leak detection. In an example, a computing device can determine site geometry of a location where a methane leak may occur. Using the site geometry and local wind data, the computing device can determine the location, orientation, and spatial extents of a scan plane. The scan plane can include scanning locations for the drone to scan for methane. The computing device can upload the flight plan to a drone that executes the flight plan, scanning for methane at the designated locations. The computing device can download data from the drone after the flight and calculate the concentration of any methane detected by the scan.Filed by Schlumberger Technology Corporation, published 2026-07-09 — illustrates the shift from fixed and handheld sensing toward autonomous, mission-planned aerial detection.

What the numbers mean for a filing decision
Three patterns worth acting on before drafting claims or scoping freedom-to-operate work in this space.
Concentration
26.2% of 347 records
held by the top 5 filers
Leadership is real but not exclusive
The top five assignees combined hold 91 of the 347 records in scope, with the leading filer alone at 25. That leaves close to three-quarters of the field spread across a long tail of single- and few-filing entrants, so a leadership position in laser or spectroscopic sensing does not foreclose adjacent approaches.
Ranking basis: 347 records, 100 ranked assignees
Momentum
+36%
2021 to 2024 filing growth
Growth held through the last complete filing year
Filings climbed from 28 in 2021 to 38 in 2024, a 36% increase, after peaking at 40 in 2022. 2025 and 2026 counts look lower only because publication lags filing by roughly 18 months — they are not evidence of a slowdown.
2024 is the most recent year treated as complete
Technology mix
58.8% vs 27.1%
G01N vs G01M share of records
Optical sensing claims dominate the field
Material analysis and testing (G01N) appears in well over half of all records, more than double the share of the next class, structure/testing balance (G01M). That gap suggests most competitive pressure sits on detection method claims rather than mechanical or structural integrity claims.
Shares exceed 100% combined because records carry multiple IPC codes

Players
Who is filing, and where the claim space still has room
Oilfield services and specialist sensing firms lead the ranked assignees, with co-filing patterns showing tight collaboration inside a small number of corporate families rather than broad industry-wide partnering.
Leader
25 records
leading assignee
A single leader well ahead of fifth place
The top-ranked assignee holds 25 records against 14 for the fifth-place filer and 9 for tenth place, a steep drop-off that marks this as a leader-plus-field structure rather than an even spread.
Based on the 100 ranked assignees in this dataset
Collaboration
10 co-assignee pairs
strongest pair: 10 shared records
Co-filing stays inside corporate families
The strongest co-assignee link, at 10 shared records, sits between entities within the same corporate group, and the next two strongest pairs (7 each) follow the same pattern. This points to internal cross-entity filing rather than cross-company joint development.
10 co-assignee pairs identified across the dataset
Momentum
0 in latest year
for several previously active filers
Recent-year activity has gone quiet across several names
A number of previously active assignees, including specialist photonics and oilfield-services filers, show zero filings in the latest year and a -100% year-on-year change. Given the roughly 18-month publication lag, this likely reflects filings still working through the pipeline rather than firms exiting the space.

What's Next
Where to take this analysis
The dataset points to specific next steps depending on whether you are drafting, clearing, or scouting.
Run a freedom-to-operate check on optical sensing claims
With 58.8% of records touching G01N, any new laser- or spectroscopy-based detection method is likely to sit close to existing claims. A targeted clearance search on the specific wavelength, optical path, or calibration method is worth doing before drafting.
Explore G01N filings in EurekaTrack the quiet filers for renewed activity
Several previously active assignees show zero filings in the latest year, which the publication lag makes ambiguous. Setting an alert on these names catches renewed filing before it becomes visible in aggregate trend data.
Set up assignee alerts in EurekaScope claims in the under-claimed branches
Drone mission planning, satellite quantification, and continuous pipeline-integrated monitoring show up as supporting technology but not as dense claim clusters. A first claim drafted specifically in one of these branches has more room to stand alone.

FAQ
Common questions on the methane detection patent landscape
Filings are concentrated among oilfield services and specialist sensing companies, with the leading assignee holding 25 of the 347 records in scope and the top five combined holding 91 records, or 26.2% of the field. That leaves close to three-quarters of the dataset spread across a long tail of smaller and single-filing entrants, so no single company controls the field outright. Anyone assessing competitive position should look at both the leader's portfolio and the density of the surrounding tail before concluding a space is closed.
Yes, through the last complete filing year: filings rose from 28 in 2021 to 38 in 2024, a 36% increase, after peaking at 40 in 2022. Counts for 2025 and 2026 appear lower in the data, but that reflects the roughly 18-month lag between filing and publication rather than an actual slowdown. Treat any year within the last two as understated rather than as evidence of declining interest.
Material analysis and testing (IPC class G01N) is the dominant category, appearing in 58.8% of the 347 records in scope, well ahead of testing/structure balance (G01M) at 27.1% and radiation/light measurement (G01J) at 14.4%. This points to optical and spectroscopic detection methods as the primary battleground for claims, with wellbore, pipeline, navigation, and data-processing classes appearing as supporting rather than core technology. A record can carry more than one class, so these figures do not sum to 100%.
Sub-areas such as drone flight-path planning for leak surveys, satellite-based emissions quantification, and pipeline-integrated continuous monitoring show up as supporting technology in the IPC mix but lack the dense claim clusters seen in optical sensing. These branches touch classes like G01C, F17D, and G06Q at single-digit percentages of the record total, suggesting the claim space there is still forming. A first claim drafted specifically for one of these use cases has more room to stand on its own than a new optical detection method would.
Patent publication typically lags the actual filing date by around 18 months, so any patent landscape's most recent one to two years will always undercount true filing activity. In this dataset, 2024 is the most recent year that can be treated as complete, and the visible drop-off in 2025 and 2026 reflects records still working through the publication pipeline rather than a real decline in filing. Analysts should anchor growth statements to 2024 or earlier and treat later years as provisional.
