Cooking Appliance Patents: Top Companies & Filing Trends 2026
- Filing activity peaked in 2023 at 50 families and has since flattened rather than continued to climb, suggesting the core claim space around heating uniformity and power control is filling up.
- F24C (stoves and ranges) and H05B (electric heating circuits) together dominate the IPC mix, while control-software classes like G05D remain comparatively thin — a gap worth checking before filing.
- Co-assignment activity is sparse only 10 co-assignee pairs across 524 families, meaning most filings come from single entities rather than joint development programmes.
Filing growth compares 2021 (35 records) with 2024 (15) — 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 524 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This landscape tracks 524 patent families published between 2015 and mid-2026 that combine cooking-appliance hardware claims — induction cooktops, oven appliances, stoves and ranges — with functional claims around heating uniformity, power control, smoke extraction, self-cleaning and sensor cooking. The IPC scope spans H05B6 (induction and dielectric heating), F24C7 (domestic cooking ranges) and A47J37 (cooking utensils), which keeps the set anchored to physical appliance design rather than general kitchen software.
Filing offices skew toward the United States and Europe, with Canada, the UK, WIPO and Australia forming a smaller secondary tier. Because publication typically lags filing by around eighteen months, the 2025–2026 counts in any trend chart understate real filing activity for those years.

Filing trends and technology composition
Family counts by year and IPC subclass show where cooking appliance R&D has concentrated and where it has pulled back.
A decade of uneven growth, now flattening
Filings rose from 12 in 2017 to a peak of 50 in 2023, roughly double the 2022 midpoint of 25. The years since the peak show no further acceleration, a pattern more consistent with a maturing claim space than with a technology still in its growth phase.
Hardware classes dominate; control software is thin
F24C (320 records) and H05B (289 records) anchor the dataset, confirming this is primarily an appliance-hardware landscape. A47J appears in 139 records, while G05D — control of non-electric variables, the class most likely to cover sensor-driven cooking logic — sits at just 53, and power-electronics classes H02J and H02M trail further behind.
Shares are the percentage of the 524 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

WO2025234948A1 — An induction cooktop and a power control method for an induction cooktop
The invention relates to an induction cooktop comprising a first cooking module and at least one second cooking module on a top plate, with induction coils in each module and a controller that compares power drawn by a first power control unit against a predefined threshold to coordinate activation across modules.Filed by Mamur Teknoloji Sistemleri, this November 2025 application illustrates current claim strategy: cross-module power arbitration on a shared cooktop, rather than single-zone heating control.

Three patterns in the dataset matter more for a filing decision than the raw counts alone.
Growth has stalled, not accelerated
The climb from 12 filings in 2017 to 50 in 2023 looked like an emerging area. The absence of further growth since suggests the core mechanical and heating-control claims are now well staked out, and new entrants face denser prior art than the trend line alone implies.
Control-software claims are comparatively open
Appliance hardware classes carry the bulk of filings, but G05D — control logic for non-electric variables — is a fraction of the size of F24C or H05B. Sensor-driven cooking algorithms and adaptive control logic look less contested than the physical heating elements they operate.
Filing is mostly solo, not joint
Only 10 co-assignee pairs appear across the full set, and the strongest of these link entities within the same corporate group rather than independent partners. Cross-company joint development is rare in this space, at least as reflected in patent co-ownership.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to cooking appliance technology, with the prior art for and against each one.

The strongest co-assignee pair links two entities within the same corporate group, filed together seven times — a pattern of internal subsidiary co-filing rather than external partnership.
Who is filing, and where the gaps sit
Recent-year momentum data shows several previously active assignees recording zero filings in the latest year, consistent with the broader plateau in the trend chart.
A broad base with a long tail
The assignee ranking spans 524 families with no single filer approaching dominance of the field. Several large appliance groups appear repeatedly, but the ranking as a whole reflects a fragmented field with many single- or low-digit filers.
Several established filers have gone quiet
Multiple assignees that filed steadily in earlier years show zero filings in the most recent tracked year. Given the typical 18-month publication lag, some of this is reporting delay rather than an actual stop — but it is worth confirming directly before assuming continued activity.
US and Europe anchor the filing map
The United States receives the largest share of filings (187), followed by the European Patent Office (130). Canada, the UK, WIPO and Australia form a smaller secondary tier, suggesting protection strategy concentrates on the two largest appliance markets first.

G05D filings trail far behind the hardware classes. A closer read of what those 53 records actually claim will show how much of adaptive cooking control is still open.
Dig into IPC detailCommon questions on cooking appliance patents
Influence in this dataset is measured by citation count within the searched corpus, and the highest-cited records include a smart cookware patent cited 290 times and a menu-driven cooking appliance control system cited 216 times. These are older filings, so high citation counts reflect years of accumulated influence rather than current filing activity. A newer entrant should treat these as foundational prior art to design around, not as evidence of who is most active today.
Filing activity rose steadily from 12 families in 2017 to a peak of 50 in 2023, but has not grown further since. Combined with the roughly 18-month publication lag, the most recent years likely understate true filing volume somewhat, but the flattening trend from the 2022 midpoint onward still points to a maturing rather than expanding field. New filers should expect denser prior art in core heating and power-control claims than a simple growth narrative would suggest.
Control-logic classes such as G05D (control of non-electric variables) carry far fewer records than the hardware-heavy F24C and H05B classes, suggesting sensor-driven and adaptive cooking algorithms are comparatively under-claimed. Power-electronics classes H02J and H02M are similarly thin relative to the core appliance hardware. Specific sub-areas worth checking include in-oven computer vision, smoke-extraction airflow control and self-cleaning cycle optimisation.
Rarely. The dataset contains only 10 co-assignee pairs across 524 total families, and the strongest pairing links two entities within the same corporate group rather than independent companies. This indicates that most protection in this field comes from single-entity filing programmes, with joint development reflected in patent ownership being the exception rather than the norm.
A representative recent filing, WO2025234948A1, claims an induction cooktop with multiple cooking modules on a shared top plate, each with its own induction coils, coordinated by a controller that compares power drawn by a first power control unit against a predefined threshold before activating additional coils. This reflects a shift toward claiming cross-module power arbitration rather than single-zone heating control alone. Anyone filing in adjacent power-control claims should check how their coordination logic differs from this threshold-comparison approach.
