Connected Baby Monitors Patents: Top Companies & Trends 2026
- 81.5% concentration. The top 5 of 20 ranked assignees account for 185 of 227 records in scope — a field with a dominant leader and a long tail.
- Filing growth is negative, not flat. The evidence shows -38% from 2021 (8) to 2024 (5), the last year publication lag allows a clean read on.
- Digital transmission dominates the claim set. H04L appears on 49.3% of the 227 records, ahead of alarm signalling (G08B, 32.6%) and wireless networking (H04W, 29.5%).
Filing growth compares 2021 (8 records) with 2024 (5) — 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 227 records in scope (CR5), not by the ranked leaders only.
What this dataset covers
This landscape draws on 227 published patent records filed between 2015 and mid-2026 that combine baby-monitor or infant vital-sign sensing claims with contactless respiration sensing, video privacy, false-alert handling, battery operation, wireless range, or medical-claim-boundary language. The scope deliberately sits at the intersection of consumer smart-home hardware and infant-safety sensing, which is why assignees best known for home security and robotics appear alongside dedicated infant-monitoring names.
Records here are counted as patent families, which is the fairer unit for comparing assignees because it neutralises continuation filings and multi-jurisdiction duplicates. Publication lags filing by roughly 18 months, so the 2025 and 2026 figures in any trend understate real filing activity and should not be read as a slowdown on their own.

Filing trend and technology composition
Two views of the same 227-record dataset: how filing activity has moved year over year, and which IPC subclasses carry the claim weight.
Filing trend, 2017-2026
Filings ran from 19 in 2017 to a peak of 26 in 2018, then eased. The cleanest recent comparison — 2021's 8 filings against 2024's 5 — shows a 38% decline over that three-year span. 2025 and 2026 figures are still filling in under normal publication lag and should not be read as a continuation of that decline.
IPC subclass composition
H04L (digital information transmission) touches 49.3% of the 227 records, reflecting how much of this field is really about getting sensor data off-device reliably. G08B (alarm systems, 32.6%) and H04W (wireless networks, 29.5%) follow, with G05B/G05D control classes and G06N (AI-based computing, 13.7%) marking where inference and automation claims sit. A61B (diagnosis and surgery, 12.8%) marks the medical-claim boundary this search was built to surface. Records can carry several classes, so these shares sum to well over 100% of the record total.
Shares are the percentage of the 227 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

US20180005125A1 — Devices, methods, and associated information processing for security in a smart-sensored home
Filed by Google LLC and published 2018-01-04, this filing describes a service robot system that autonomously moves within a structure to perform household tasks while transmitting an indication of its own activity over a wireless interface, paired with a home security system whose motion sensors are configured to distinguish the robot's own movement from other activity in the home.The distinguishing-intrusion logic is the part that matters for infant monitoring: any system that must tell a caregiver's or robot's own motion apart from an infant's is treading on this same functional ground.

Three patterns stand out once filing volume, technology mix and citation weight are read together.
One leader, a long tail behind it
The leading assignee holds 117 of the 227 records outright, with the remaining top-5 share filled by four companies far smaller in volume. By the tenth-ranked assignee, filing counts have dropped to 4 — the ranked list of 20 companies is the entire set the data endpoint returns, not a curated top slice.
Activity has cooled from its 2018 peak
Filings peaked at 26 in 2018 and have since trended down, with the clean 2021-to-2024 comparison showing a 38% decline. Because publication lags filing by about 18 months, the 2025-2026 figures are not yet reliable evidence of further decline.
Data transmission, not sensing hardware, dominates claims
Nearly half the corpus sits in digital transmission (H04L), well ahead of dedicated alarm signalling or AI-based computing classes. That suggests the contested ground is how sensor data is moved and alerted on, not the sensors themselves.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to connected baby monitors and sensing, with the prior art for and against each one.
| Assignee | Co-assignee | Shared families |
|---|---|---|
| Master Lock Co Inc | VARDR | 6 |
The strongest co-assignee pairing in this dataset appears 6 times, indicating that most filings here are single-assignee rather than joint-development efforts.
Who is filing, and where the gate sits
Filing here is dominated by one company with a large smart-home and robotics portfolio, with home-security, robotics and dedicated infant-monitoring names filling the rest of the ranked list.
A single company holds over half the field
The top-ranked assignee accounts for 117 of the 227 records in scope, more than four times the next four companies combined. Its recent-year momentum has flattened to zero new filings in the latest year, consistent with the broader cooling trend.
Smaller assignees are the ones still filing
P TECH LLC shows +100% year-on-year momentum with 2 filings in the latest year, while several larger, historically active assignees show zero filings in the same period. Momentum has shifted toward smaller, more recent entrants even as aggregate volume falls.
The gap after the top 10 is steep
Combined, the top 10 of 20 ranked assignees hold 216 of 227 records (95.2%), leaving very little volume for assignees ranked below tenth. This is a field where filing outside the ranked leaders means entering largely uncontested claim space, or space too thin to be worth ranking.

Where to take this analysis
The dataset points to a field with high transmission-claim density at the top and thinner coverage in sensing accuracy and privacy handling further down.
Map the white space in respiration sensing
Contactless respiration sensing and false-alert suppression sit under a much smaller share of records than transmission and alarm claims, suggesting room to file narrowly on sensing accuracy rather than the broader system architecture.
Explore in EurekaWatch the mid-tier for freedom-to-operate risk
Smaller assignees with rising recent-year momentum are the ones most likely to file new claims in the near term, even as aggregate volume cools; tracking their filings closely matters more than watching the dominant leader.

One assignee holds 117 of the 227 records in this dataset, well ahead of the rest of the field. The top 5 of 20 ranked assignees together account for 185 records, or 81.5% of all records in scope, so filing activity is heavily concentrated at the top rather than spread evenly. Below the top 10, which together hold 95.2% of records, filing counts drop sharply, leaving a long tail of single- or few-filing entrants.
Filing peaked at 26 records in 2018 and has since declined; the cleanest recent comparison, 2021's 8 filings against 2024's 5, shows a 38% decrease over that span. Figures for 2025 and 2026 are still incomplete because patent publication typically lags filing by about 18 months, so they should not yet be read as confirming a continued decline. Anyone assessing momentum should anchor on 2024 as the most recent complete year.
Digital information transmission (H04L) appears on 49.3% of the 227 records, making it the single largest technology class, ahead of alarm and signalling systems (G08B, 32.6%) and wireless networking (H04W, 29.5%). Control systems and AI-based computing classes each appear on a smaller share, and diagnosis-related claims (A61B) sit at 12.8%. Because a single record can carry multiple IPC classes, these shares add up to well over 100% of the record total.
Contactless respiration sensing accuracy, video privacy masking at the edge, and false-alert suppression logic all sit well below the dominant transmission and alarm classes in claim density, suggesting narrower, technically specific claims in these areas face less crowded prior art. Battery-operation duty-cycling and medical-claim-boundary language are similarly thinner. A first claim in these areas would do well to specify the sensing modality and a concrete accuracy or false-positive threshold rather than claiming the system architecture broadly.
Citation counts in this dataset favour older filings because they have simply been available longer to accumulate citations from later applicants, not because they are more relevant now. The most-cited record here dates to an early physiological monitoring patent with over two thousand citations, but that reflects historical influence rather than current claim risk. For assessing what blocks a design today, claim scope and filing recency matter more than raw citation count.

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.
