Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 20-21 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 20 recites the limitation "heating patterns" at line 6 renders the claim indefinite. It is unclear for whether this heating patterns is the same as the one recited in the preceding claim 13 at line 10. If it is so, then "the" or "said" should be used, i.e. “the heating patterns”.
Furthermore, it is unclear and indefinite to the relationship between “heating pattern” and “heating patterns” as recited in the preceding claim 13 at 10 and to whether they are the same or different. Further clarification is required to either further differentiate (heating pattern).
Furthermore, it is unclear and indefinite to the relationship between “heating pattern” at lines 10 and 13 and “heating patterns” as recited in the preceding claims 13 at 10 and to whether they are the same or different. Further clarification is required to either further differentiate (heating pattern).
Furthermore, there is insufficient antecedent basis for the limitation “the heating patter” at line 16 in the claim.
Regarding claim 21, there is insufficient antecedent basis for the limitation “the group” at line 2 in the claim.
Claim Rejections - 35 USC § 103
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.
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.
Claim(s) 13-17 and 21-25 are rejected under 35 U.S.C. 103 as being unpatentable over Rober et al. (US 20150289324) in view of Hallgren et al. (US 20130186887).
Regarding claim 13, Rober discloses a method for operating a household microwave appliance 20 (fig. 2, i.e. called a microwave oven) (¶ 0065), said method comprising:
loading a cooking compartment (56) with food (Abstract, i.e. called food items) to be cooked;
performing an initial scan by supplying microwaves into the cooking compartment using at least two different parameter configurations (¶ 0015, 0039, i.e. a set of temperature signals and cooking parameters: cooking temperatures, power levels, cooking time, rotational platter positions, rotational platter speeds,…) set in a control apparatus (¶ 0020-0022, 0031, i.e. called a controller including a control panel 22 and a control module 68), with the food treatable differently in a localized manner using the microwaves having the at least two different parameter configurations (¶ 0019-0020, 0055, 0057, 0061, 0068),
measuring with a thermal imaging sensor temperature distributions (62, 64, 66) associated with the at least two different parameter configurations (¶ 0015, 0039, i.e. a set of temperature signals and cooking parameters: cooking temperatures, power levels, cooking time, rotational platter positions, rotational platter speeds,…) on a surface of the food (¶ 0026).
Rober et al. discloses all the limitations of the claimed invention as set forth above, except for determining heating patterns from differences of the temperature distributions, and following the initial scan
(a) setting at least one target temperature distribution for the food, based on a standardized target state and a prevailing temperature distribution;
(b) determining, based on the prevailing temperature distribution, a most suitable heating pattern for achieving the at least one target temperature distribution;
(c) applying to the food microwaves having a sequence of the at least two different parameter configurations associated with the most suitable heating pattern; and
(d) determining as a new prevailing temperature distribution the previously prevailing temperature distribution in addition to the most suitable heating pattern.
However, Hallgren teaches determining heating patterns (303) from differences of the temperature distributions (¶ 0008-0010, 0073), and following the initial scan
(a) setting at least one target temperature distribution (301, i.e. a desire temperature pattern) for the food (102, i.e. called a load), based on a standardized target state (¶ 0026, i.e. called a suitable finishing temperature) and a prevailing temperature distribution (¶ 0026-0027, i.e. instantaneous temperature) (¶ 0050, 0083);
(b) determining, based on the prevailing temperature distribution (¶ 0027, i.e. instantaneous temperature), a most suitable heating pattern (¶ 0027, i.e. a corresponding heating pattern) for achieving the at least one target temperature distribution (301, i.e. a desire temperature pattern) (¶ 0027, 0046);
(c) applying to the food microwaves having a sequence of the at least two different parameter (¶ 0059, i.e. operating parameters from look-up table or memory in which suitable finishing temperatures of different food types are stored.) configurations associated with the most suitable heating pattern (¶ 0078); and
(d) determining as a new prevailing temperature distribution (¶ 0030, i.e. a more suitable desired temperature pattern) the previously prevailing temperature distribution (i.e. instantaneous temperature) in addition to the most suitable heating pattern (¶ 0035).
The combination of references are analogous art because they are from the same field of endeavor of a microwave heating apparatus. Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Rober and Hallgren before him or her, to include such heating patterns from differences of temperature distributions of Hallgren because they automatically obtain a desired
temperature pattern based on the information provided by the recognizing means (typically a set of sensors) and thereby determine a corresponding heating pattern. Information about the type of food in a region of the load is useful in determining a suitable finishing temperature for the region. Information about the weights and/or volumes of the regions of the load is useful in determining how much microwave energy is needed to heat a particular region, and therefore in determining the time required for heating such a region. Information about the instantaneous temperatures of the regions of the load is useful for dynamic control of the heating and in particular for determining if further heating of any of the regions is necessary, and in that case how much heating is needed. The suggestion/motivation for doing so would have been obvious because it improves the efficiency of the heating as taught by Hallgren (¶ 0024).
With respect to claim 14, Rober in view of Hallgren discloses the limitations of the claimed invention as set forth above of which Hallgren further discloses repeating steps (a) to (d) (see claim 13 above) until the prevailing temperature distribution (i.e. instantaneous temperature) meets a predetermined cancellation criterion (¶ 0040, i.e. the load has reached a certain temperature).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Rober and Hallgren before him or her, to include such condition/criterion of Hallgren because based on the desired temperature pattern, different zones of the cavity are provided with different levels of microwave intensities. The suggestion/motivation for doing so would have been obvious because it reduces the risk of damaging the microwave heating apparatus.
With respect to claims 15-16, Rober in view of Hallgren discloses the limitations of the claimed invention as set forth above of which Hallgren further discloses wherein the predetermined cancellation criterion comprises that the prevailing temperature distribution (i.e. instantaneous temperature) reaches or exceeds a predetermined limit temperature calculated from a quantity of energy that is required to perform a phase transformation in the food (¶ 0077); and (Claim 16) wherein the phase transformation is performed of water (¶ 0035).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Rober and Hallgren before him or her, to include such condition/criterion of Hallgren because based on the desired temperature pattern, different zones of the cavity are provided with different levels of microwave intensities. The suggestion/motivation for doing so would have been obvious because it reduces the risk of damaging the microwave heating apparatus.
With respect to claim 17, Rober in view of Hallgren discloses the limitations of the claimed invention as set forth above of which Hallgren further discloses measuring, in addition to steps (a) to (d) (see claim 13 above), with the thermal imaging sensor the temperature distribution of the food (102, i.e. called a load) (¶0030-0033), wherein the cancellation criterion comprises that the measured temperature distribution reaches or exceeds a predetermined limit temperature (¶ 0077).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Rober and Hallgren before him or her, to include such condition/criterion of Hallgren because based on the desired temperature pattern, different zones of the cavity are provided with different levels of microwave intensities. The suggestion/motivation for doing so would have been obvious because it reduces the risk of damaging the microwave heating apparatus.
With respect to claim 21, Rober in view of Hallgren discloses the limitations of the claimed invention as set forth above of which Rober further discloses wherein the at least one setting parameter comprises at least one setting parameter selected from the group consisting of angle of rotation of a rotary antenna, angle of rotation of a rotary plate (58, i.e. called a rotating platter), position of a mode stirrer, microwave frequency of a semiconductor-based microwave generator, and phase difference between microwaves that are supplied into the cooking compartment from different feed-in locations or ports (¶ 0039, 0046).
With respect to claim 22, Rober in view of Hallgren discloses the limitations of the claimed invention as set forth above of which Hallgren further discloses wherein the food (102, i.e. called a load) that is introduced into the cooking compartment (101, i.e. called cavity) is frozen food (¶ 0002, 0030).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Rober and Hallgren before him or her, to include such food item(s) of Hallgren because multiple items of different types can be heated simultaneously and differently, thereby saving both time and energy. The suggestion/motivation for doing so would have been obvious because it ensures that all parts of the food in the microwave oven are properly heated (¶ 0002).
With respect to claim 23, Rober in view of Hallgren discloses the limitations of the claimed invention as set forth above of which Hallgren further discloses wherein the food (abstract, i.e. called food items) that is introduced into the cooking compartment is food that is not frozen (e.g. popcorn, burrito,...) (¶ 0022).
With respect to claim 24, Rober in view of Hallgren discloses the limitations of the claimed invention as set forth above of which Hallgren further discloses performing a further initial scan after multiple repetitions of steps (a) to (d) (see claim 13 above), and subsequently repeating steps (a) to (d) based on the further performed initial scan (¶ 0009, 0085).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Rober and Hallgren before him or her, to include such steps of Hallgren because they automatically obtains a desired temperature pattern based on the information provided by the recognizing means (typically a set of sensors) and thereby determine a corresponding heating pattern. Information about the type of food in a region of the load is useful in determining a suitable finishing temperature for the region. Information about the weights and/or volumes of the regions of the load is useful in determining how much microwave energy is needed to heat a particular region, and therefore in determining the time required for heating such a region. Information about the instantaneous temperatures of the regions of the load is useful for dynamic control of the heating and in particular for determining if further heating of any of the regions is necessary, and in that case how much heating is needed. The suggestion/motivation for doing so would have been obvious because it improves the efficiency of the heating (0024).
With respect to claim 25, Rober in view of Hallgren discloses the limitations of the claimed invention as set forth above of which Rober further discloses a household microwave appliance 20 (fig. 2, i.e. called a microwave oven), comprising:
a cooking compartment (56) configured to be loaded with food (abstract, i.e. called food items);
a microwave generator (¶ 0015, i.e. called a microwave radiation generator) generating microwaves to which the food (abstract, i.e. called food items) and located in the cooking compartment (56) is exposed (¶ 0020);
a thermal imaging sensor (62, 64, 66) oriented into the cooking compartment (56) and configured to determine temperature distributions on a surface of the food to be cooked (abstract; ¶ 0031); and
a control apparatus (¶ 0020-0022, i.e. called a controller including a control panel 22 and a control module 68.) configured to set multiple parameter configurations of setting parameters of the household microwave appliance (20), with at least two parameter configurations (¶ 0039, i.e. cooking parameter setpoints (such as desired cooking temperatures. And a secondary cooking parameter controller (¶ 0040, i.e. a temperature controller))) treating the food to be cooked differently with the microwaves in a localized manner,
wherein the household microwave appliance 20 (fig. 2, i.e. called a microwave oven) is configured to implement a method as set forth in claim 16 (see claim 16 above).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Rober and Hallgren before him or her, to include such a phase transformation, in particular of water of Hallgren because based on the desired temperature pattern, different zones of the cavity are provided with different levels of microwave intensities. The suggestion/motivation for doing so would have been obvious because it reduces the risk of damaging the microwave heating apparatus.
