Infant Feeding Bottles and Teats Patents: Leaders & Trends 2026
- Concentrated but not locked up. the top 5 assignees hold 22.3% of all 969 records in scope, and the top 10 hold 31.0% — leaving most of the field to single- and low-count filers.
- Filing has cooled from its 2018 peak. activity peaked at 60 records in 2018 and fell -62% from 2021 (47) to 2024 (18), the last year with a complete publication picture.
- Claims cluster hard on the container itself. A61J containers for medicine cover 52.7% of records, while adjacent classes like A61B diagnosis/surgery and A23L foods sit in the single digits.
Filing growth compares 2021 (47 records) with 2024 (18) — 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 969 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This landscape tracks 969 published records matching feeding bottle, bottle teat and anti-colic bottle terminology combined with functional claims around flow rate, venting systems, material migration, sterilization cycles, nipple confusion and cleaning access. The window runs from 2015 through the 2026-07-31 data cut-off, though the most recent one to two years are still filling in as publications catch up with filings.
Records here span consumer-facing bottle and teat hardware as well as adjacent medical-device and materials filings that got pulled in through shared functional language — that is why microorganism and diagnostic classes appear alongside kitchenware ones in the technology composition below.
Filing trend and technology composition
Two views of the same 969 records: how filing activity has moved year over year, and which IPC subclasses the claims actually sit in.
A 2018 peak, then a step down
Annual filings rose to a peak of 60 in 2018, then declined; the evidence-backed comparison of 2021 (47) to 2024 (18) shows a -62% drop over that span. Treat 2025 and 2026 figures as provisional — publication typically lags filing by around 18 months, so recent years will fill in as more records publish.
Containers dominate; the rest is a long tail
A61J (containers for medicine) appears on 52.7% of the 969 records, far ahead of A61M devices for body fluids (7.0%), B65D containers and packaging (5.9%), A47J kitchen utensils (5.7%), A61B diagnosis and surgery (5.2%), C12N microorganisms (4.7%), A47G household equipment (4.5%) and A23L foods (4.1%). Because records can carry multiple classes, these shares sum to more than 100%.
Shares are the percentage of the 969 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

AU2025203445A1 — A Valved Feeding Bottle Teat
The filing describes a feeding bottle teat with a bulbous and conical nipple section, internal support structures running around the inner circumference, and a valve that passes through an annular flange with a protruding section extending below the flange's lower surface.Filed by Australian Baby Company Pty Ltd, published 2025-12-04.

Three read-outs from the filing record that matter more to a filing decision than a single headline number.
Leadership is thin, not dominant
A single leader holds a visibly larger share than the rest of the ranked field, but the top 5 combined still account for only 22.3% of all 969 records, and the top 10 for 31.0%. Most of the landscape sits with assignees who appear only a handful of times.
Activity has stepped down from its peak
Filings peaked in 2018 at 60 records and have declined since, with the last fully comparable window showing a drop from 47 in 2021 to 18 in 2024. This is a real slowdown, not an artefact of publication lag, since 2024 is treated as complete.
The container itself is the crowded ground
Over half of all 969 records carry an A61J containers-for-medicine classification, meaning bottle and teat hardware claims sit on dense prior art. Adjacent classes tied to diagnostics, food composition and microorganisms are each claimed on well under 10% of records.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to infant feeding bottles and teats, with the prior art for and against each one.
Who is filing, and where they are not
The ranked assignee list returned by the dataset covers 100 companies — not a top-50 or top-100 cut, but the full ranking the endpoint returns. Recent-year momentum for the leading names has gone quiet across the board.
One name well ahead of the pack
The leading assignee's record count is more than five times the fifth-place total of 18, marking it out clearly from an otherwise closely bunched field.
A tight cluster below the leader
Fifth place sits at 18 records and tenth place at 16 — a narrow four-record spread across five positions, suggesting no single challenger is pulling away from the group.
A small cluster of joint filers
Ten co-assignee pairs appear in the data, with the strongest three pairs each sharing 16 records — evidence of a tight design-and-filing relationship among a small group rather than broad industry co-filing.

Where to take this next
The dataset points to specific next steps depending on whether the goal is freedom-to-operate, portfolio benchmarking or identifying acquisition targets.
Check the under-claimed branches first
Venting geometry, migration testing and sterilization-rated compounds carry far fewer records than the core container class — worth a targeted search before committing claim language there.
Explore white space in EurekaWatch the mid-field, not just the leader
The tight spread between 5th and 10th place suggests competitive positioning could shift with a handful of new filings — worth tracking these assignees' activity going forward.

The dataset ranks 100 assignees by record count, with a single leader holding 100 records, clearly ahead of the fifth-ranked assignee at 18. The top 5 assignees together account for 22.3% of the 969 records in scope, and the top 10 account for 31.0%, meaning the majority of filings come from companies outside this ranked group. This points to a field with one clear leader but a long tail of smaller filers rather than a tightly controlled oligopoly.
Filing activity peaked in 2018 at 60 records and has declined since. The most reliable recent comparison — 2021 at 47 records versus 2024 at 18 records, a -62% change — shows a genuine slowdown rather than a temporary dip, since 2024 is treated as the last complete filing year. Figures for 2025 and 2026 will rise as publications catch up, given the roughly 18-month lag between filing and publication, so it is too early to read those years as a continuation of the decline.
The overwhelming majority sit under A61J, containers for medicine, which covers 52.7% of the 969 records in scope. Smaller but notable shares fall under A61M devices for body fluids (7.0%), B65D containers and packaging (5.9%), and A47J kitchen utensils (5.7%), with diagnostic, microorganism and food-composition classes each below 5%. Because a single record can carry multiple IPC classes, these percentages add up to more than 100%.
The core bottle and teat container claims are dense, but adjacent functional areas — anti-colic valve venting geometry, material-migration testing protocols, sterilization-cycle-rated compounds and flow-rate calibration by feeding stage — carry far fewer records relative to the A61J core. These are not guaranteed to be open, since related filings can sit in other IPC classes not captured directly here, but they are reasonable starting points for a freedom-to-operate search before drafting new claims.
The most-cited record in this landscape is US20160220743A1, a sensor network for breast pumping mothers, cited 173 times, followed by older foundational filings including US4813932A on a single-handed breast pump and US5730336A on a dispensing valve for flexible liquid containers. High citation counts tend to favour older patents that have simply had more time to accumulate citations within the searched corpus, so these should be read as influential prior art rather than as the most commercially relevant patents active today.

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.
