Baby monitor and infant sleep sensing patents: who holds the claims and where the field is still open
Concentrated at the top. The top 5 assignees hold 186 of 270 records in scope (68.9%), and the top 10 hold 225 (83.3%) — a small group has staked out most of the claim space. Filings rose from 17 in 2017 to a peak of 53 in 2018, then eased. Comparing the two most recent complete years, 2021 (24 records) to 2024 (12 records) shows a 50% decline — a genuine cooling of the field rather than a data artefact, since both years are past the publication lag window.

Common questions on baby monitor and sleep sensing patents
Who are the leading patent holders in baby monitor and infant sleep sensing technology?
The field is concentrated: the top five assignees hold 186 of the 270 records in scope, or 68.9%, and the top ten hold 225, or 83.3%. The leading assignee alone accounts for 80 records, well ahead of the fifth-place holder at 20 and the tenth-place holder at 6. That said, 67 companies appear in the ranking, so there is a genuine long tail of smaller filers working narrower claims outside the leading group.
Is patent filing activity in this space growing or slowing down?
Filing peaked in 2018 at 53 records and has cooled since. Comparing the two most recent complete years, 2021 to 2024, volume fell from 24 to 12 records, a 50% decline. Because publication typically lags filing by around 18 months, the years closest to the data cut-off will always look artificially thin, so this decline is measured on the last years that can fairly be called complete rather than on the very latest data.
What technology areas do these patents actually claim?
Digital transmission claims (IPC class H04L) appear in 40.4% of the 270 records, followed by diagnosis and surgery claims (A61B) at 27.0%, radar and positioning (G01S) at 23.0%, and wireless networking (H04W) at 22.6%. Video-specific claims (H04N) sit lower at 12.6%, meaning the field is more heavily contested in how signals are sensed and transmitted wirelessly than in the camera hardware itself. A single record can carry several of these classes, so the figures naturally add to more than 100%.
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 Baby Monitors and Sleep Sensing 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.
