Claim Rejections – 35 USC § 103
1. In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
2. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1-5, 7-9, 11-12, and 15 are rejected under 35 U.S.C. 103 rejected under 35 USC 103 as being unpatentable over Boscaino (EP 1767869 A2) in view of Klouda (DE 202004015292 U1).
Regarding Claim 1, Boscaino teaches a cooking device comprising:
a housing (Fig. 3, cooking chamber 2),
a blower (Fig. 2, fan 23), which comprises a blower wheel (Fig. 2, fan wheel 22),
which is provided with a blower motor (Fig. 2, motor 24),
which comprises a driving shaft (See “Snag-It” diagram below),
which is drivingly connected to the blower wheel (See “Snag-It” diagram below), and
a ring channel (Fig. 2, See “Snag-It” diagram directly below; Ring Channel is the space within the boundary of the diagram), which is in flow communication (See also “Snag-It” diagram directly below) with an intake opening of the housing (Fig. 2, opening 27),

Wherein a heating device is arranged in the ring channel (Fig. 2, heating element 34, and “Snag-It” diagram above, showing the heating element 34 clearly within “the gap” between the motor 24 and the hub of the fan wheel 22. Note: the application claim(s) and specification describe the “ring channel” as the space between the blower motor 10 and the blower wheel 7. Therefore, when the “the gap” of the “ring channel” is extended vertically, the heating element 34 is clearly “arranged in the ring channel”), and
a water injection nozzle (See Fig. 2, inlet conduit 7C & “Snag-It” diagram below) is arranged in the ring channel adjacent to the heating device of the ring channel (See “Snag-It” diagram below, specifically showing the water injection nozzle 7C adjacent, as defined by Merriam-Webster as “nearby,” not “distant” and within “proximity” of the heating element 34).

Boscaino does not teach
Klauda teaches a housing, in which an openable and closable cooking chamber is arranged (Fig. 1, device housing 2, cooking space 1, baking sheet 4, oven door 3).
Boscaino doesn’t explicitly disclose that the cooking chamber is openable and closeable. However, para. 0025 of Boscaino discloses that there are foods place on trays 20 within a cooking zone 20.
Klouda discloses a cooking device with an openable and closeable cooking chamber (Fig. 1, oven door 3).
It would have been obvious to modify Boscaino in view of Klouda, by incorporating an openable and closeable door on the cooking chamber, in order to provide a means of placing and removing food from the cooking chamber, and also closing and sealing the cooking chamber during a cooking operation to retain heat and moisture for efficient cooking of the food.
15. Claim 6 is rejected under 35 USC 103 as being unpatentable over Boscaino (EP 1767869 A2) in view of Klouda (DE 202004015292 U1), in further view of Kohlstrung (FR 2807822 A1).
16. Regarding Claim 6, Boscaino, as modified above, teaches the cooking device according to claim 1,
Boscaino as modified above does not teach a nozzle for cleaning is provided.
Kohlstrung teaches a nozzle for cleaning is provided (See Fig. 1, pump 14, cleaning medium 20, pump line 13, inlet orifice 12, & Fig. 2, ring 11, nozzles 10).
It would have been obvious to a person having ordinary skill in the art before the effective date of the claimed invention to modify Boscaino as modified above to provide a cleaning medium (cleaning fluid) and one or more cleaning nozzles for the purpose of removing deposits and increasing cleanliness of components as taught by Kohlstrung. A person of ordinary skill in the art would have been motivated to use cleaning fluid through the use of one or more spray nozzles for cleaning the ring chamber so as to beneficially assist in reducing or eliminating cleaning tools or other components that must be introduced into the interior of the cooking appliance and subsequently removed after cleaning, increase cleaning efficiency, and ultimately reduce the time, materials, and effort required to effect a clean and efficient cooking appliance.
17. Claim 10 is rejected under 35 USC 103 as being unpatentable over Boscaino (EP 1767869 A2) in view of Klouda (DE 202004015292 U1), in further view of Chen (CN 212089219 U).
18. Regarding Claim 10, Boscaino, as modified above, teaches the cooking device according to claim 1, and
Boscaino as modified above does not teach the blower motor is arranged axially offset in the direction of the cooking chamber. It is the examiner’s position that the broadest reasonable interpretation of this limitation, consistent with the specification, merely means that the blower motor is positioned on a horizontal axis relative to, or in a direction of the cooking chamber. The fixed position of the blower motor will inherently be axially offset relative to a position it could be, in a direction away from the cooking chamber. This interpretation is consistent with what’s disclosed in paragraph 0066 of the published application, i.e. US 2024/0255155.
Chen teaches the blower motor is arranged axially offset in the direction of the cooking chamber (Fig. 3, fan 211, motor 212, pot body/cooking chamber 111).
It would have been obvious to a person having ordinary skill in the art before the effective date of the claimed invention to modify Boscaino as modified above to provide for the installation of a blower motor that is axially offset in the direction of the cooking chamber by modifying the motor/blower fan shaft configuration as taught by Chen. A person of ordinary skill in the art would have been motivated to provide a blower motor design configured so that that is axially offset in the direction of the cooking chamber for the purpose of simply incorporating a known configuration in the art that would yield the predictable result of creating air flow via the blower motor.
19. Claims 13-14 are rejected under 35 USC 103 as being unpatentable over Boscaino (EP 1767869 A2) in view of Klouda (DE 202004015292 U1, in further view of Siegfried (CH 631884 A5).
20. Regarding Claim 13, Boscaino, as modified above, teaches the cooking device according to claim 11,
Boscaino does not teach a condenser which is connected to the housing outlet.
Siegfried teaches a condenser (Fig. 1, cooking chamber 4, condensate drain pipe 22, condensate discharge device C & “Snag-It” diagram below) which is connected to the housing outlet (See “Snag-It” diagram below).

It would have been obvious to a person having ordinary skill in the art before the effective date of the claimed invention to modify Boscaino as modified above to provide for a condenser assembly for the purpose of removing excess steam that has changed state to water as taught by Siegfried. A person of ordinary skill in the art would have been motivated to use a condenser assembly to beneficially assist in removable of excess cooled water that has condensed and pooled in the lower section of the cooking chamber for the purpose of maintaining a cooking atmosphere that is favorable for browning, appearance, and taste of the food prepared by the use of hot air and in further support of the efficient cooking of foodstuffs during the operation of the oven apparatus.
21. Regarding Claim 14, Boscaino as modified above teaches the cooking device according to claim 13,
Boscaino as modified above does not teach the condenser comprises an outlet pipe.
Siegfried teaches the condenser comprises an outlet pipe (condensate drain pipe 22, condensate discharge device C & “Snag-It” diagram above).
It would have been obvious to a person having ordinary skill in the art before the effective date of the claimed invention to modify Boscaino as modified above to provide for a condenser assembly including a condensate discharge pipe for the purpose of removing steam that has changed state to water as taught by Siegfried. A person of ordinary skill in the art would have been motivated to use an outlet pipe to beneficially assist in the removable of excess cooled water that has condensed and pooled in lower section of the cooking chamber by ejecting it through an outlet pipe for the purpose of maintaining a cooking climate that is favorable for browning, appearance, and taste of the food prepared by the use of hot air cooking oven.
