Three families, one grant, and 31 software hires pointing somewhere else
Norbert Health holds 3 patent families: 1 granted and 2 published and pending. Filing began in 2021, with the most recent published filing dated 2024-12-12. The families appear in 1 patent office: United States.Patent figures from Google Patents Public Data, reviewed 2026-09-14. Funding: $14M Series A, HCVC, LDV Capital and C4 Ventures, 2026-09-01.
Norbert Health filed its first contactless-sensing family in 2021, waited three years, then filed twice more. One is granted. Meanwhile the hiring plan is dominated by software and AI. The question is whether the thing being built next is the thing the claims describe.
The money arrives twenty-one months later
A $14M Series A from HCVC, LDV Capital and C4 Ventures. Norbert Health was founded in 2019, and the first patent filing predates this round by several years. That order matters. The claims were not written to decorate a pitch; they were written when the company was small and nobody outside it was paying for the answer.
The last public filing is dated 2024-12-12, twenty-one months before this round closed. Anything filed since then is still inside the eighteen-month publication window and invisible. So the portfolio a reader can inspect today is the pre-money portfolio. Whatever the Series A bought in the way of new filings has not surfaced yet.
One solid tick, two thin ones
Three families since 2021, all filed in the United States. One granted, two published and pending, with further grants expected around 2027. The velocity tells the story better than the count: one filing in 2021, nothing in 2022 or 2023, then two in 2024. A single early bet, a long quiet stretch, then a deliberate return to the same ground.
The titles are close to identical. Contactless sensor-driven assessment of oxygen saturation. Contactless cardiovascular and respiratory assessment from face and hand imaging, twice. This is not three ideas. It is one idea being fenced from three directions: the physiology being measured, the body parts being imaged, the method of getting from pixels to a vital sign.
One granted family is enforceable today. Two are promises with dates attached.
Alexandre Winter is on all three
Six inventors are named across the portfolio. Alexandre G Winter appears on three of three. Jonathan Platkiewicz also appears on three. Alexis Bienvenu is on two. The rest appear once. That is a tight authorship pattern for a company of this stage, and it means the invention record and the founding record are close to the same document.
Concentration like this cuts both ways. It shows conviction: the same two people returned to the same problem across a three-year gap rather than drifting. It also means the technical memory of why each claim is worded the way it is sits with a very small number of people, and the 2024 filings extend rather than replace what they wrote in 2021.
Philips has six hundred and eighty six
The claims cluster in A61B, diagnosis and surgery. Over the last five years the same CPC groups drew Philips with 686 families, Samsung with 644, Biosense Webster Israel with 388, Zhejiang University with 372, Medtronic with 289 and Huawei with 282. On this scale three families is a dot. Volume is not the thing to compare here.
In a space this dense, count stops being informative and scope takes over. A narrow claim that nobody else wrote is worth more than fifty broad ones already anticipated. The useful reading of Norbert Health's file is therefore not how much it filed but how specifically: face and hand imaging, oxygen saturation, contactless. That is a corridor inside A61B, not a landgrab across it.
Four organizations already point back here
Citations have started arriving. Valid It Evaluation Solutions with two citing publications, Hill Rom Services with two, Hamai Electric Lamp with one, Wistron with one, Cook Kashtin with one. A three-family portfolio filed from 2021 onward is being read by hospital equipment, lighting and contract electronics names. That is an unusual spread of readers for a home health device company.
Citations are not endorsements, but they are evidence of position. They mean examiners and drafters in adjacent industries found this work sitting in their path. For a portfolio this small, being cited at all suggests the 2021 filing landed early enough in contactless imaging-based vital signs to become prior art that others must write around.
The claims say biology, the hiring says software
Here is the tension. The three families claim contactless physiological assessment, firmly in A61B. The hiring plan is 60 roles: 31 in software and AI, 8 in bio and clinical, 8 in hardware, 7 other, 4 go-to-market, 2 in ops and finance. Open positions include a Computer Vision/ML Engineer, a Chief Medical Officer and a COO. A company builds what it hires for.
So the moat is real and it is narrow. One granted family, enforceable today, in a corridor the company reached before the money did, in a CPC neighbourhood so crowded that being early is the whole advantage. The open question is whether the product the software hires ship in 2026 sits inside that corridor or a few steps beside it.
Filing in biology, hiring in software: the next product may sit outside the current claims.
Is a three-family portfolio enough before launch?
Three signals below each say something about whether the claims cover the product. None of them settles it alone. A grant without scope, or scope without continuity, leaves the same gap open.
A filing record, not a moat
Three families in a CPC neighbourhood led by Philips and Samsung, with nothing enforceable and no evidence the claims follow the product.
The claims say biology, the hiring says software
When the post-Series-A filings publish, do they extend the face-and-hand imaging corridor or open a second one around the software and AI work?
Does the granted family's claim scope cover the inference layer between sensor data and a reported vital sign, or only the sensing arrangement?
Do Alexandre G Winter and Jonathan Platkiewicz remain on the new filings, or does a broader inventor set appear alongside the 31 software and AI hires?
Does the arrival of a Chief Medical Officer shift filing activity toward clinical validation claims rather than device and imaging claims?
Following those four would tell you whether the 2021 bet becomes the foundation of the company or a well-drafted footnote to it.

How many patents does Norbert Health have?
Norbert Health holds 3 patent families as reviewed in 2026-09: 1 granted and 2 published and pending.
How many of Norbert Health's patents are granted?
1 of the 3 families is granted, or 33 percent. The remaining 2 are published and still under examination.
What technology do Norbert Health's patents cover?
Norbert Health's claims cluster in diagnosis and surgery (A61B). Recent filing titles include "contactless sensor-driven device, system and method enabling assessment of oxygen saturation" and "contactless sensor-driven device, system and method providing cardiovascular and respiratory assessment based on face and hand imaging".
Where has Norbert Health filed patents?
Norbert Health's families appear in 1 patent office: United States.
Which companies file patents in the same areas as Norbert Health?
The same CPC groups drew Philips, Samsung, Biosense Webster Israel and Zhejiang University over the last five years. Shared classification indicates a common technology field rather than direct competition.
Who cites Norbert Health's patents?
Patent records from Valid It Evaluation Solutions, Hill Rom Services, Hamai Electric Lamp and Wistron cite Norbert Health's filings. A citation indicates a reference to the work, not evidence of commercial use.
Who invented Norbert Health's patents?
