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 Objections
Claims 23, 27, and 42 are objected to because of the following informalities:
In the 4th line of claim 23, “communicating port” should be corrected to --communication port-- for consistency throughout the claims.
In the last 2 lines of the 2nd paragraph of claim 23, “a direction in which the device is used in the apparatus main body” is claimed. The end of the 5th paragraph of claim 23 recites the limitation “a predetermined direction in which the device is used in the apparatus main body”. It appears that these two limitations are describing the same direction. Additionally, dependent claims refer to “the predetermined direction”. As such, it is suggested for the limitation in the last 2 lines of the 2nd paragraph to be amended to --a predetermined direction in which the device is used in the apparatus main body--, and the limitation at the end of the 5th paragraph to be amended to --the predetermined direction--.
The 1st line of claim 27 recites “The device according to claim 24,” but then refers to the limitation “the virtual circle” which is first introduced in claim 26. It appears as though claim 27 should be corrected to be dependent upon claim 26.
The last line of claim 42 recites the limitation “each of the part of the electrodes”. This appears to be a typographical error that should be corrected to --each of the pair of the electrodes--.
Appropriate correction is required.
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.

Claims 23, 25-41 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-3, 6-11, and 13-19 of U.S. Patent No. 12,253,811 (“the patent”) in view of Kakuta et al. (US 2009/0297178; “Kakuta”).
Regarding outstanding claim 23, though slight differences in wording, claim 1 of the patent claims most of the limitations except for the “roller” configured to bear the developer, and the “detecting member for use in outputting a signal based on the amount of the developer accommodated in the container”. See below.
Outstanding claim 23
Claim 1 of the patent
A device for use in an apparatus main body of an image forming apparatus, the device comprising:
A developing device for use in an apparatus main body of an image forming device, the developing device comprising:
a container which includes first and second chambers accommodating a developer and which is provided with a communicating port through which the first and second chambers communicate with each other, the first and second chambers being integrally formed, the second chamber being disposed below the first chamber when the device is oriented in a direction in which the device is used in the apparatus main body;
a developing container including an accommodation chamber configured to accommodate a developer and a developing chamber communicating with the accommodation chamber through a communication port, the accommodation chamber and developing chamber being integrally formed such that the developing chamber is disposed below the accommodation chamber in a state where the developing device is in use in the apparatus main body;
a
a developer carrier configured to carry the developer accommodated in the developing chamber;
a conveyance member which is configured to convey, by being rotated, the developer in the first chamber toward the second chamber through the communication port and which includes a shaft, and a sheet having first and second end portions on opposite sides in a direction perpendicular to the rotation axis, the first end portion of the sheet being fixed to the shaft; and
a conveyance member provided in the accommodation chamber and including a rotation shaft rotatable about a rotation axis and a sheet which is rotatable together with the rotation shaft, is flexible, and has a first end portion fixed to the rotation shaft in a direction perpendicular to the rotation shaft axis, the conveyance member being configured to convey the developer in the accommodation chamber toward the developing chamber through the communication port by the sheet while being rotated; …
wherein the developer container includes an abutting surface which forms the accommodation chamber and which is configured to abut a second end portion of the sheet opposite to the first end portion of the sheet in the direction perpendicular to the rotation axis
a detecting member provided in the first chamber of the container , the detecting member being provided above the communication port when the device is oriented in a predetermined direction in which the device is used in the apparatus main body,
a light guide provided in the accommodation chamber of the developing container, the light guide being configured to guide light from outside of the developing device into the accommodation chamber and from inside of the accommodation chamber toward outside of the developing device and being positioned above the communication port when the developing device is in use in the apparatus main body;
wherein the conveyance member and the container are configured so that the second end portion of the sheet is maintained in a bent state by contacting an inner surface constituting the first chamber of the container until the second end portion of the sheet passes in front of an upstream end of the communication port in a rotation direction of the conveyance member and then reaches the detecting member.
wherein the developer container includes an abutting surface which forms the accommodation chamber and which is configured to abut a second end portion of the sheet opposite to the first end portion of the sheet in the direction perpendicular to the rotation axis such that the sheet is maintained in a bent state until the second end portion of the sheet passes in front of an upstream end of the communication port in a rotation direction of the conveyance member and then reaches the light guide.
As mentioned above, claim 1 of the patent fails to claim a “roller” configured to bear the developer, and the “detecting member for use in outputting a signal based on the amount of the developer accommodated in the container”.
Kakuta teaches a similar developing device 4, comprising a roller 17 configured to bear developer accommodated in a second chamber 18b (Fig. 1 [0146]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to claim a roller as the developer carrier of the patent. It has been held that the simple substitution of one known element for another to obtain predictable results is obvious. In this instance, the predictable results would be providing an appropriate amount of developer to a photosensitive member in order to properly develop a latent image and result in high-quality printing.
Kakuta further teaches utilizing a light guide 42 in an accommodation chamber 18a of the developing container 4 as a detecting member for use in outputting a signal based on the amount of the developer accommodated in the container (Figs. 1 & 7 [0155, 0163-0169]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to claim the light guide of the patent utilized as a detecting member for use in outputting a signal based on the amount of the developer accommodated in the container. One would have been motivated to do so in order to detect a remaining toner amount stably with accuracy (Kakuta [0169]).
Regarding outstanding claim 34, modified claim 1 of the patent claims the device according to claim 23, but fails to claim wherein the detecting member is provided in a concave part of the inner wall of the first chamber which is recessed toward an outside of the first chamber.
Kakuta teaches providing the detecting member 42 in a concave part of the inner wall of the first chamber 18a which is recessed toward an outside of the first chamber (see Fig. 1).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to claim wherein the detecting member is provided in a concave part of the inner wall of the first chamber which is recessed toward an outside of the first chamber, since it has been held to be within the general skill of a worker in the art to combine prior art elements according to known methods to yield predictable results. In this instance, the predictable results would be the accurate detection of remaining developer within the chamber.
The outstanding claims below clearly correlate with the claims of the patent as follows:

*Note regarding outstanding claim 29 and patent claim 7: limitations describing wherein the at least one connector extends, “in a direction inclined with respect to a direction perpendicular to the rotation axis” and “in a direction intersecting with the rotation axis” are interpreted as having the same scope, as the at least one connector is a three dimensional object and thus will have some dimension extending in every direction.
Claims 24 and 42 are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of the patent 12,253,811 in view of Kakuta (US 2009/0297178) as applied to claim 23, and further in view of Kanno (US 2019/0235413).
Regarding outstanding claim 24, modified claim 1 of the patent claims the device according to claim 23, but fails to claim wherein the detecting member includes a pair of electrodes between which a voltage is applied from an outside of the device.
Kanno teaches utilizing, as a detecting member to detect an amount of remaining developer, a pair of electrodes 31/32 between which a voltage is applied from an outside of a similar developing device 4 (Figs. 5-6 [0046-0047, 0058, 0060-0064]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to claim wherein the detecting member includes a pair of electrodes between which a voltage is applied from an outside of the device. One would have been motivated to do so in order to stably detect the toner remaining amount (Kanno [0073]).
Regarding outstanding claim 42, modified claim 1 of the patent claims the device according to claim 24, but fails to claim wherein the pair of electrodes faces each other and each of the part (i.e., pair) of the electrodes includes a portion exposed outside of the container.
Kanno teaches a configuration in which the pair of electrodes 31/32 faces each other and each of the pair of the electrodes includes a portion exposed outside of the container (see Fig. 6 [0058]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to claim wherein the pair of electrodes faces each other and each of the part (i.e., pair) of the electrodes includes a portion exposed outside of the container. One would have been motivated to do so in order to stably detect the toner remaining amount (Kanno [0073]).
