Wearable ECG Patents: Who Leads, Where the Gaps Are 2026
- Filings are accelerating, not maturing. annual publications climbed from 2 in 2017 to 6 in 2026, with a flat midpoint in 2022 — the field went quiet, then restarted.
- India now outpaces the US as a filing venue. 12 receiving-office filings from India versus 11 from the United States signals a second, academically-driven filing centre alongside the traditional device-maker base.
- The dataset is thin and fragmented. 23 total families with only 10 co-assignee pairs, most from Indian engineering colleges — there is no single dominant corporate assignee to design around yet.
What this landscape covers
This landscape tracks patent families at the intersection of wearable ECG hardware and ambulatory cardiac monitoring workflows — devices and methods addressing electrode-skin impedance, arrhythmia detection, wear duration, signal quality index and adhesive comfort, classified predominantly under A61B5 diagnostic sensing. The corpus is small: 23 published families spanning 2015 to mid-2026, which makes single filers visible in a way they would not be in a larger field.
Because publication typically lags filing by around 18 months, the 2026 count of 6 is a floor, not a ceiling — the true filing rate for the most recent year will only become visible in later data pulls. Read the trend's shape, not its endpoint.
Filing trend and technology composition
Two views of the same 23-family corpus: how filing activity has moved year over year, and which IPC subclasses the claims actually sit in.
Filings rebuilt after a flat midpoint
Annual publications rose from 2 in 2017 to a peak of 6 in 2026, but 2022 recorded zero — the field paused before restarting, which reads as accelerating rather than steadily growing.
Diagnostic sensing dominates; signal-processing claims are thin
All 23 records touch A61B diagnosis and surgery claims, with a much smaller cluster in G16H healthcare informatics and single-digit counts in G06F data processing, H03F amplifiers and H03M coding — the electronics and signal-chain side of the problem is comparatively unclaimed.
Shares are the percentage of the 23 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Remote ambulatory cardiac monitoring system for acquiring ECG signals (US10993633B2)
A system and method for a multi-function remote ambulatory cardiac monitoring system. The system includes a housing and a microprocessor disposed within the housing. The microprocessor controls the remote ambulatory cardiac monitoring system. The system also includes an electrode for sensing ECG signals and the electrode being in communication with the microprocessor. An integrated cellular module also is included in the system, and the cellular module is connected to the microprocessor and disposed within the housing. The integrated cellular module transmits ECG signals to a remote center.Filed by ACS Diagnostics; granted 2021-05-04. Combines the electrode, housing microprocessor and an integrated cellular radio into one claimed system rather than treating connectivity as an external accessory.

Citation counts favour older records simply because they have had longer to accumulate citations inside this corpus — treat them as markers of influence on the field's vocabulary, not as evidence that a route is still commercially central.
Publication numbers are shown where the record carries one (8 of 8 rows); clicking a row searches Eureka by that number.

Three read-outs from the dataset that matter more than the raw counts.
Growth resumed after a dead year
The midpoint year, 2022, shows zero filings in this dataset, then activity resumed and reached its recorded peak of 6 in 2026. That pattern looks less like steady technology maturation and more like renewed interest from a new filer base — worth watching for whether it holds or was a one-off cluster.
India edges ahead as a filing venue
India's 12 filings against the US's 11 is a near-even split, but it is notable that India leads at all in a category historically dominated by US device makers — much of that volume traces to academic institutions rather than corporations.
A small, fragmented field
With only 23 families and 10 co-assignee pairs recorded, no single entity has built a defensible claim thicket. That makes freedom-to-operate analysis tractable now, but it also means the picture can shift quickly with a handful of new filings.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to wearable ecg and cardiac monitoring, with the prior art for and against each one.
Who is filing, and who is missing
The assignee base splits between a handful of established device companies and a cluster of Indian academic co-inventors filing in small groups — there is no dominant corporate leader in this dataset.
Academic filers driving recent momentum
Varun P George and Sreeram P, both affiliated with Government Engineering College Thrissur, and Narula Institute of Technology each show 1 filing in the latest year — the visible momentum right now sits with academic groups rather than incumbent device makers.
Incumbent device makers have gone quiet recently
Applied Cardiac Systems shows no filings in the latest tracked year despite anchoring some of the corpus's most-cited prior art, consistent with a company harvesting an earlier filing position rather than actively expanding it.
Some academic filers have already dropped off
Saveetha Institute of Medical & Technical Sciences shows a 100% year-over-year decline to zero latest-year filings, a reminder that academic filing bursts in this space can be short-lived rather than sustained programmes.

Where to take this analysis
The raw counts point to a fragmented, early-stage field — the next step is usually to pressure-test a specific claim route against this corpus rather than read the trend lines alone.

This dataset tracks 23 published patent families filed between 2015 and mid-2026, all classified under diagnostic sensing (A61B) with smaller clusters in healthcare informatics, data processing, amplifier and coding subclasses. That is a small corpus compared to more mature wearable categories, which means individual filings carry more relative weight and freedom-to-operate checks are still tractable manually. The count will grow as later years' filings publish, since publication lags filing by roughly 18 months.
The dataset shows no single dominant corporate assignee; instead it splits between established device makers such as Applied Cardiac Systems, whose earlier filings account for some of the most-cited prior art, and a newer cluster of Indian academic co-inventors, including groups at Government Engineering College Thrissur, filing smaller numbers of recent applications. This fragmented structure is unusual for a wearable health category and suggests the field has not yet consolidated around a small set of incumbents.
Yes, based on the tracked data: annual filings rose from 2 in 2017 to a recorded peak of 6 in 2026, though the midpoint year 2022 shows zero filings, meaning the growth is better described as a resumption than a steady climb. Because 2026 data is still incoming, the true recent-year rate is likely higher than currently visible. Treat the 2026 figure as a floor rather than a final count.
India and the United States are the two receiving offices recorded in this dataset, with India at 12 filings and the United States at 11 — a near-even split that is notable because it puts an academically-driven filing base in India roughly on par with the traditional US device-maker base. Readers evaluating filing strategy should note that Indian filings here trace substantially to academic institutions rather than corporations.
US10993633B2, assigned to ACS Diagnostics and granted 2021-05-04, claims a remote ambulatory cardiac monitoring system that combines a housing, a control microprocessor, an ECG-sensing electrode and an integrated cellular module for transmitting signals to a remote center within one claimed assembly. It principally blocks designs that bundle all four elements — housing, processor, electrode and onboard cellular radio — into a single integrated device. Designs that keep connectivity external, use a companion app for transmission, or route data over Bluetooth to a separate gateway rather than an integrated cellular module sit further from this claim's core language, though a full clearance opinion would need to review the granted claim set in detail.

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.
