DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
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 7-9, 17, 19 and depending claim 18 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 pre-AIA the applicant regards as the invention.
Claims 7-9, 17, 19 recite “a second time” and “the second time”. It is unclear whether or not a first time is required by the claim, therefore the bolded phrases make the claimed limitations indefinite. For the purpose of examination, it is interpreted as only one time is claimed.
Claims 8, 18 recite “a flow of air”. It is unclear if the bolded limitation refers to the previously claimed limitation in claims 1, 18. Not only does the phrase in claim 8 lacks a definite article (e.g. the or said) but the limitation is inconsistently recited.
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 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.
The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Mitchell (US 2021/0318051 A1), in view of Junge (US 2018/0142934 A1), and in view of Wernicki (4,727,720).
Claim 1: Mitchell discloses a method of operating an ice maker appliance (FIG.3), the method comprising:
determining, with a home position sensor (paragraph [63]: position sensor 298), that a portion (inherent as part of structure of the assembly) of an ice making assembly (200) of the ice maker appliance is in a home position (to clarify, the ice making assembly at zero position used as home position; paragraphs [63] [64]: controller with knowledge of the position of the ice making assembly 200 include a position sensor 298);
rotating the portion of the ice making assembly (200) from the home position towards a harvest position (paragraph [64] [65]: the ice making assembly 200 rotates toward predetermined position, ready for harvest); and
Mitchell discloses the claimed limitations in claim 1, but fails to disclose determining, with a harvest position sensor, that the portion of the ice making assembly did not reach the harvest position; directing a flow of air to the portion of the ice making assembly in response to determining that the portion of the ice making assembly did not reach the harvest position, whereby ice in the portion of the ice making assembly is vaporized.
However, Junge teaches determining, with a harvest position sensor (paragraph [30]: level sensor 205 to sense whether or not a level of ice stored in ice bin is at full or not), that the portion of the ice making assembly did not reach the harvest position (paragraph [30]) for the purpose of determining the level of ice stored in the ice bin (paragraph [30]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention was made to modify the apparatus of Mitchell to include determining, with a harvest position sensor, that the portion of the ice making assembly did not reach the harvest position as taught by Junge in order to determine the level of ice stored in the ice bin.
Further, Wernicki teaches directing a flow of air (column 3 lines 17-23: heat from ambient warm air flows through walls of ice extractor 15 melting lose any ice that is adhering to the inside of the ice extractor and ice falls to ice chute, and drops from there into ice bin) to the portion of the ice making assembly in response to determining that the portion of the ice making assembly did not reach the harvest position, whereby ice in the portion of the ice making assembly is vaporized (to clarify, as the result of flow of warm air causing ice to melt or evaporates when any ice causing the assembly not to reach harvest mode) for the purpose of preventing the ice cube from hanging up during harvest (column 1 lines 50-53).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention was made to modify the apparatus of Mitchell to include directing a flow of air to the portion of the ice making assembly in response to determining that the portion of the ice making assembly did not reach the harvest position, whereby ice in the portion of the ice making assembly is vaporized as taught by Wernicki in order to prevent the ice cube from hanging up during harvest.
Claim 2: Mitchell as modified discloses the apparatus as claimed in claim 1, wherein the portion of the ice making assembly comprises a carriage (yoke wheel used as carriage; paragraph [64] [65]: yoke wheel of the ice making assembly 200 rotates toward predetermined position, ready for harvest).
Claim 3: Mitchell as modified discloses the apparatus as claimed in claim 1, further comprising suspending an ice making operation (Junge; paragraph [48]: making ice is suspended when harvesting operation is complete when ice bin is full harvesting is deactivated) in response to determining that the portion of the ice making assembly (Junge; ice making system 200) did not reach the harvest position (Junge; paragraph [48]).
Claim 4: Mitchell as modified discloses the apparatus as claimed in claim 1, further comprising rotating the portion (paragraph [64] [65]: the ice making assembly 200 rotates toward predetermined position, ready for harvest) of the ice making assembly (200) to the home position after determining that the portion of the ice making assembly did not reach the harvest position (Wernicki; to clarify, when ice hanging up in harvest, then warm air flows through) and before directing the flow of air to the portion of the ice making assembly (Wernicki; column 3 lines 17-23: heat from ambient warm air flows through walls of ice extractor 15 melting lose any ice that is adhering to the inside of the ice extractor and ice falls to ice chute, and drops from there into ice bin).
Claim 5: Mitchell as modified discloses the apparatus as claimed in claim 1, wherein directing the flow of air (Wernicki; column 3 lines 17-23) to the portion of the ice making assembly (200) comprises directing the flow of air from an evaporator (Junge; 170) of a sealed system (Junge; paragraph [31]: refrigerator includes sealed system) of the ice maker appliance (FIG.3).
Claim 6: Mitchell as modified discloses the apparatus as claimed in claim 5, wherein directing the flow of air to the portion (Wernicki; column 3 lines 17-23) of the ice making assembly (200) further comprises operating a fan (Junge; 180) of the ice maker appliance (FIG.3) at a maximum speed (Junge; to clarify, fan is capable of running as max speed if needed; paragraph [44]: to vary the speed of fan 180 to influence temperature) and operating the sealed system at one hundred percent (Junge teaches variation of speed of fan, except for operating the sealed system at one hundred percent. It would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention was made to further modify the apparatus of Junge to include operating the sealed system at one hundred percent in order to influence temperature of the warm air (paragraph [44]), since it has been held that discovering an optimum value of a result effective variable involves only routine skill in the art. Please note that in the instant application - Optimum value: MPEP 2144.05 II-B).
Claim 7: Mitchell as modified discloses the apparatus as claimed in claim 1, further comprising rotating the portion (paragraph [64] [65]: the ice making assembly 200 rotates toward predetermined position, ready for harvest) of the ice making assembly (200) towards the harvest position a second time after directing the flow of air (Wernicki; column 3 lines 17-23) to the portion of the ice making assembly (200).
Claim 8: Mitchell as modified discloses the apparatus as claimed in claim 7, further comprising
determining, with the harvest position sensor (Junge; 205), that the portion of the ice making assembly did not reach the harvest position (Junge; to clarify, level sensor 205 determines whether or not ice level is full or not ready to harvest) when rotating the portion (paragraph [64] [65]: the ice making assembly 200 rotates toward predetermined position, ready for harvest) of the ice making assembly (200) towards the harvest position the second time after directing the flow of air (Wernicki; column 3 lines 17-23: heat from ambient warm air flows through walls of ice extractor 15 melting lose any ice that is adhering to the inside of the ice extractor and ice falls to ice chute, and drops from there into ice bin) to the portion of the ice making assembly (200), and
directing a flow of air (Wernicki; column 3 lines 17-23) to the portion of the ice making assembly (200) in response to determining that the portion of the ice making assembly (200) did not reach the harvest position when rotating the portion of the ice making assembly (200) towards the harvest position the second time after directing the flow of air (Wernicki; column 3 lines 17-23) to the portion of the ice making assembly (200), whereby ice in the portion of the ice making assembly is vaporized (Wernicki; as the result of flow of warm air causing ice to melt or evaporates when any ice causing the assembly not to reach harvest mode).
Claim 9: Mitchell as modified discloses the apparatus as claimed in claim 7, further comprising
determining, with the harvest position sensor (Junge; 205), that the portion of the ice making assembly (200) reached the harvest position (Junge; to clarify, level sensor 205 determines whether or not ice level is full or not ready to harvest) when rotating the portion of the ice making assembly (200) towards the harvest position the second time after directing the flow of air (Wernicki; column 3 lines 17-23: heat from ambient warm air flows through walls of ice extractor 15 melting lose any ice that is adhering to the inside of the ice extractor and ice falls to ice chute, and drops from there into ice bin) to the portion of the ice making assembly (200);
rotating the portion of the ice making assembly (200) to the home position from the harvest position (paragraph [64] [65]: the ice making assembly 200 rotates toward predetermined position, ready for harvest); and
initiating an ice making cycle (Junge; based on broadest reasonable interpretation, once the assembly is ready to form ice it means ice making cycle is initiated; the ice making cycle is initiated when ice maker 200 is in an ice making mode; see paragraph [43]) in response to determining that the portion of the ice making assembly reached the harvest position (Junge; level sensor 205 determines whether or not ice level is full or not ready to harvest).
Claim 10: Mitchell as modified discloses the apparatus as claimed in claim 1, wherein the ice in the portion of the ice making assembly (200) is vaporized (Wernicki; as the result of flow of warm air causing ice to melt or evaporates when any ice causing the assembly not to reach harvest mode) without activating a heater (Junge; heater 214) in the ice making assembly (200).
Claim 11: Mitchell discloses an ice maker appliance (FIG.3), comprising:
an ice making assembly (200); and
a controller (164), the controller configured for:
determining, with a home position sensor (paragraph [63]: position sensor 298), that a portion (inherent as part of structure of the assembly) of the ice making assembly is in a home position (to clarify, the ice making assembly at zero position used as home position; paragraphs [63] [64]: controller with knowledge of the position of the ice making assembly 200 include a position sensor 298);
rotating the portion of the ice making assembly from the home position towards a harvest position (paragraph [64] [65]: the ice making assembly 200 rotates toward predetermined position, ready for harvest);
Mitchell discloses the claimed limitations in claim 11, but fails to disclose determining, with a harvest position sensor, that the portion of the ice making assembly did not reach the harvest position; and directing a flow of air to the portion of the ice making assembly in response to determining that the portion of the ice making assembly did not reach the harvest position, whereby ice in the portion of the ice making assembly is vaporized.
However, Junge teaches determining, with a harvest position sensor (paragraph [30]: level sensor 205 to sense whether or not a level of ice stored in ice bin is at full or not), that the portion of the ice making assembly did not reach the harvest position (paragraph [30]) for the purpose of determining the level of ice stored in the ice bin (paragraph [30]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention was made to modify the apparatus of Mitchell to include determining, with a harvest position sensor, that the portion of the ice making assembly did not reach the harvest position as taught by Junge in order to determine the level of ice stored in the ice bin.
Further, Wernicki teaches directing a flow of air (column 3 lines 17-23: heat from ambient warm air flows through walls of ice extractor 15 melting lose any ice that is adhering to the inside of the ice extractor and ice falls to ice chute, and drops from there into ice bin) to the portion of the ice making assembly in response to determining that the portion of the ice making assembly did not reach the harvest position, whereby ice in the portion of the ice making assembly is vaporized (to clarify, as the result of flow of warm air causing ice to melt or evaporates when any ice causing the assembly not to reach harvest mode) for the purpose of preventing the ice cube from hanging up during harvest (column 1 lines 50-53).
