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.

It would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention to modify the magnetic circuit of Azima such that the magnetic circuit includes multiple magnetic parts with different magnetization directions to effectively improve sound quality and treble effect. See at least Zhu abstract. Regarding the following: loudspeaker comprising a housing, an electronic component, and a transducer, the housing forming a cavity that accommodates the transducer and the air-conduction loudspeaker, Zhu teaches the speaker 100 can be applied to the sound box, earphone, mobile phone and other electronic device. See at least Zhu on page 6, lines 11-13. Azima in view of Zhu does not explicitly teach a loudspeaker comprising a housing, an electronic component, and a transducer, the housing forming a cavity that accommodates the transducer and the air-conduction loudspeaker. However, QI in related field (speaker housed in an ear device) teaches a bone conduction speaker 1400 including a vibration device 1401 and covert electrical signals to sound signals that are transmitted to the user through air conduction or bone conduction. See at least [0095], [0096], [0097], Figure 33 shows a structure of a dual-microphone speaker according to some embodiments of the present disclosure. As shown in FIG. 33, the speaker 3300 may include a vibration device 3301, a housing 3302, an elastic element 3303, an air conduction microphone 3304, a vibration sensor 3305, and an opening 3306. The vibration sensor 3305 may be a closed microphone, a dual-connected microphone, or a bone conduction microphone. It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to accommodate the transducer in a dual-microphone speaker or a bone conduction speaker depending on its intended use and provide an improved sound quality.
As to Claim 23, Azima teaches a transducer (an inertial vibration transducer 9, Figure 6), comprising: a magnetic circuit system including a magnet (magnet assembly 15, Figure 6), a magnetic conductive plate (pole forming member 14, Figure 6) and a magnetic conductive cover (the magnet assembly is shielded by means of disc-like screens (121). See at least page 6, [006]-[0008], the magnet ( 15) and the magnetic conductive plate( 14) being arranged along a vibration direction of the transducer ( transducer 9, Figure 6); and a vibration plate including a first vibration plate ( top suspension member 59) and a second vibration plate( bottom suspension members 59), the first vibration plate ( top suspension member 59) or the second vibration plate( bottom suspension member 59) being fixed on both sides of the magnet(15, Figure 6) along the vibration direction of the transducer ( transducer 9, Figure 6) for elastically supporting the magnet ( 15, the outer faces of the magnets (15) are bonded or otherwise secured to the centre portions of the members (59), whereby the magnet assembly (14,15) is located concentrically with respect to the coil (13) and is capable of limited axial movement relative thereto. See at least page 6 line 36-41). Regarding the following: wherein at least one of the magnet, the magnetic conductive plate, and the magnetic conductive cover includes multiple magnetic parts with different magnetization directions, Azima teaches magnet 15 having North or South polarity but does not explicitly teach wherein at least one of the magnet, the magnetic conductive plate, and the magnetic conductive cover includes multiple magnetic parts with different magnetization directions. However, Zhu in related field (Speaker) teaches the magnetic circuit system 4 comprises respectively voice coil 22 opposite to the two sides of the first magnetic part 41 and the second magnetic part 42, the second magnetic part 42 comprises at least one second magnetic member 421, the first magnetic part 41 comprises at least three first magnetic member 412. so that the second magnetic member 421 and the first magnetic part 41 of at least three first magnetic member 412 on the diaphragm 21 and the voice coil 22 opposite two sides to form a strong magnetic field, so that the vibration system 2 of the diaphragm 21 and the voice coil 22 in the strong magnetic field intensity; and the magnetic induction line at the diaphragm 21 is distributed uniformly, the change of the magnetic field intensity has good linearity, it can effectively improve the sound quality of the audio output by the speaker 100, and improve the effect. It would have been obvious to one of ordinary skill in the art, before the effective filing date of the invention to modify the magnetic circuit of Azima such that the magnetic circuit includes multiple magnetic parts with different magnetization directions to effectively improve sound quality and treble effect. See at least Zhu abstract. Regarding the following: an acoustic output device, comprising a fixing component and a loudspeaker, wherein the fixing component is connected to the loudspeaker, and the loudspeaker includes: a housing, an electronic component, and a transducer, the housing forming a cavity that accommodates the transducer and the air-conduction loudspeaker, Zhu teaches the speaker 100 can be applied to the sound box, earphone, mobile phone and other electronic device. See at least Zhu on page 6, lines 11-13. Azima in view of Zhu does not explicitly teach an acoustic output device, comprising a fixing component and a loudspeaker, wherein the fixing component is connected to the loudspeaker, and the loudspeaker includes: a housing, an electronic component, and a transducer, the housing forming a cavity that accommodates the transducer and the air-conduction loudspeaker. However, QI in related field (speaker housed in an ear device) teaches a bone conduction speaker 1400 including a vibration device 1401 and covert electrical signals to sound signals that are transmitted to the user through air conduction or bone conduction. See at least [0095], [0096], [0097]. On Figure 18, QI teaches a microphone or a vibration sensor connected to a housing. a side wall of the microphone 1803 may be connected to a side wall 1801 of the housing through a connection structure 3102 and form a cantilever connection.
