Prior art

Here is an analysis of the prior art cited in US patent 11,672,377. The patent includes a list of 214 cited references. Due to the extensive number of citations, a detailed claim-by-claim anticipation analysis under 35 U.S.C. § 102 for each reference would require a comprehensive review of each cited patent's full specification and claims, which is beyond the scope of this high-level summary. Instead, I will provide the requested citation details for the initial set of references and offer a general assessment of their potential relevance to the independent claims of US11672377 based primarily on their titles.

The independent claims of US11672377 generally relate to a cooking system with:

• A housing having first and second internal compartments separated by a dividing wall.
• First and second removable cooking containers, each defining a cooking volume and closing off an opening to its respective compartment.
• Independent first and second heating elements for each cooking volume.
• Independent first and second fans for each cooking volume, for air circulation.
• The ability to independently operate and program heating assemblies (fans and heating elements) to cook food in separate cooking modes simultaneously.
• Containers configured to engage with channels in the housing to define air ducts for circulation.

Below are details for some of the cited prior art, highlighting those that appear most relevant to these features based on their titles.

Cited Prior Art for US11672377

1. US5832812A

• Full Citation: US5832812A
• Publication Date: 1998-11-10
• Priority Date: 1997-02-25
• Brief Description: Device for heating and/or cooking food.
• Potential Anticipation (35 U.S.C. § 102): The title "Dual conveyer oven" suggests a cooking device with multiple cooking zones or capabilities, which broadly overlaps with the concept of multiple compartments in US11672377. It may potentially anticipate features related to multiple cooking areas and their associated heating/conveyance, particularly those in claims 1, 12, and 18 relating to dual compartments.

2. US6545251B2

• Full Citation: US6545251B2
• Publication Date: 2003-04-08
• Priority Date: 2000-10-26
• Brief Description: Cooking oven.
• Potential Anticipation (35 U.S.C. § 102): The generic title "Cooking oven" makes it difficult to assess specific anticipation without further detail. It likely covers fundamental aspects of ovens but its direct relevance to the dual-compartment, independent operation, and air circulation features of US11672377 claims 1, 12, and 18 is unclear from the title alone.

3. US6593552B1

• Full Citation: US6593552B1
• Publication Date: 2003-07-15
• Priority Date: 2002-01-14
• Brief Description: Food serving set for roasting oven.
• Potential Anticipation (35 U.S.C. § 102): The title "Food serving set for roasting oven" suggests an accessory or component for an oven. It might be relevant to aspects of cooking containers or inserts as mentioned in US11672377's description, but it's unlikely to directly anticipate the core dual-compartment, independent heating/fan system of claims 1, 12, and 18.

4. US6653602B2

• Full Citation: US6653602B2
• Publication Date: 2003-11-25
• Priority Date: 2002-01-14
• Brief Description: Food serving set for roasting oven.
• Potential Anticipation (35 U.S.C. § 102): Similar to US6593552B1, this patent's title "Food serving set for roasting oven" suggests an accessory. Its relevance to the primary claims of US11672377 (dual compartments, independent operation, fans) is likely limited.

5. US6758206B1

• Full Citation: US6758206B1
• Publication Date: 2004-07-06
• Priority Date: 2003-03-12
• Brief Description: Cooling and combustion airflow supply system for a gas range.
• Potential Anticipation (35 U.S.C. § 102): The title indicates a focus on "airflow supply system" in a "gas range," which could potentially be relevant to the fan and air circulation aspects of US11672377, particularly claims 1 and 18 which mention fans and air ducts. However, it's for a gas range, not an electric cooking system with distinct compartments, so direct anticipation of the entire claimed invention is less likely.

6. US6761159B1

• Full Citation: US6761159B1
• Publication Date: 2004-07-13
• Priority Date: 2003-03-12
• Brief Description: Exhaust cooling system for a cooking appliance.
• Potential Anticipation (35 U.S.C. § 102): "Exhaust cooling system for a cooking appliance" relates to managing airflow in a cooking device. This may be relevant to the general concept of air movement and circulation, as well as the vent (80) mentioned in the description of US11672377. It could potentially anticipate aspects of claims 1, 12, and 18 that involve fans and air circulation, but likely not the dual-compartment or independent operational aspects in their entirety.

7. US6878904B2

• Full Citation: US6878904B2
• Publication Date: 2005-04-12
• Priority Date: 2003-01-27
• Brief Description: Grilling station.
• Potential Anticipation (35 U.S.C. § 102): The title "Grilling station" suggests a specific type of cooking appliance. Without more detail, its direct relevance to the dual-compartment, independently operable air-circulating cooking system of US11672377 (claims 1, 12, 18) is not immediately clear.

8. US6917017B2

• Full Citation: US6917017B2
• Publication Date: 2005-07-12
• Priority Date: 2002-08-23
• Brief Description: Counter-top cooker having multiple heating elements.
• Potential Anticipation (35 U.S.C. § 102): The title "Counter-top cooker having multiple heating elements" is highly relevant. It directly points to "multiple heating elements" which could imply multiple cooking zones or the ability to independently control heating. This patent potentially anticipates aspects of claims 1 and 12, particularly the presence of multiple heating elements and their independent operability, although the presence of distinct compartments, independent fans, and specific air duct configurations would need closer examination.

Most Relevant Prior Art (based on titles)

From the initial set and the general themes of US11672377's independent claims, US6917017B2 ("Counter-top cooker having multiple heating elements") appears to be among the most relevant. Its title directly addresses the concept of multiple heating sources, which is a foundational element for the dual-zone independent cooking capabilities central to claims 1, 12, and 18 of US11672377. While its full disclosure would need to be reviewed to determine if it teaches the specific combination of dual compartments, removable containers, independent fans, and structured air ducts, the presence of "multiple heating elements" suggests it could address a key aspect of the invention.

Other patents with titles like US5832812A ("Dual conveyer oven") also indicate relevance due to the "dual" aspect, suggesting multiple cooking zones, a core feature of the claims in US11672377. References pertaining to "airflow supply" or "exhaust cooling systems" (e.g., US6758206B1, US6761159B1) could be relevant to the fan and air circulation elements of US11672377, particularly claims 1 and 18.

Summary of Remaining Citations

The provided patent text lists many other citations (from US7064297B2 onwards, through US11598466B2). A scan of the titles of these remaining 200+ patents reveals a wide range of cooking appliance technologies, including:

• Various types of ovens (microwave, convection, steam, combination).
• Cooktops, ranges, and grills.
• Air fryers and deep fryers (e.g., US9943209B2 "Air fryer for a full size convection oven", US10064483B2 "Air fryer for a full size convection oven").
• Multi-cookers and multi-functional appliances (e.g., US9247854B2 "Multi-cooker system").
• Specific components like heating elements, fans, and control systems.
• Containers, baskets, and racks for cooking.
• Appliances with multiple cavities or drawers (e.g., US9655474B2 "Cooking appliance having at least two drawers", US11266205B2 "Multi-zone cooking appliance").
• Ovens with improved airflow or heat distribution.

Many of these patents, particularly those mentioning "air fryer," "multi-zone," "multi-cavity," or "dual," could potentially anticipate various elements or combinations of elements found in US11672377's claims. For example, patents discussing air fryers would be relevant to the fan-driven heated air circulation. Those discussing "multi-zone" or "multiple cavities" would be highly relevant to the dual-compartment structure and independent operation.

A thorough assessment would require an in-depth review of each patent's claims and specification to determine if all elements of any given independent claim of US11672377 are present in a single prior art reference, or if the combination of elements would have been obvious in light of the prior art (35 U.S.C. § 103).
