Conrad teaches a hand vacuum cleaner (abstract) that comprises clean air outlets positioned around hand vacuum cleaner (see para 0083). It would have been obvious to one of ordinary skill in the art before effective filing date of the claimed invention to have further modified Kamimura wherein the hand vacuum cleaner comprises two clean air outlets positioned on opposed lateral sides of the hand vacuum cleaner based on teachings of Conrad. This modification would allow for clean air to be exhausted even when there is a clog in one clean air outlet. (see para 0054, 0081,0083 of Conrad). Claim(s) 19-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kamimura (JP2008206613A) in view of Conrad (US20110314630A1), Yamada (JP2013230302A) and Ohara (JP2002085297A), Regarding claim 19, Kamimura teaches a hand vacuum cleaner (abstract) having (see annotated figure below) an upper end, a lower end, a front end having a dirty air inlet (11, figure 1) and a rear end, the hand vacuum cleaner comprising: (a) an air flow path (“when the user operates the switch 20, the electric blower 8 is activated by the electric power from the rechargeable battery 9, and the fan 7 is rotated. A suction airflow is generated which is sucked through the pipe-shaped member 15, passes through the dust collection unit 5 and the electric blower 8, and is discharged out of the machine casing 4 through the exhaust path (not shown). Thus, the electric vacuum cleaner 8 is moved so that the first suction port 11 is brought close to the surface to be cleaned G”) extending from the dirty air inlet (11, figure 1) to a clean air outlet (“discharged out of the machine casing 4 through the exhaust path”), the air flow path comprising an inlet conduit (15, figure 1) that is positioned at the upper end of the hand vacuum cleaner, wherein the inlet conduit has a conduit axis; (b) a cyclone assembly (5, figure 1) positioned in the air flow path, the cyclone assembly comprising a cyclone (“Further, eddy current generating means 13 is detachably attached in the container 5A of the dust collecting part 5, and the eddy current generating means 13 makes the dust collecting part 5 a cyclone separator”) having a front end (see front of 5, figure 1) and a rear end (see rear of 5, figure 1) and a cyclone axis of rotation (see Y, figure 1) that extends through the front and rear ends of the cyclone, wherein the inlet conduit extends from the dirty air inlet to the cyclone (see 12, figure 1); (c) a suction motor (6, figure 1) positioned in the air flow path rearward of the cyclone, the suction motor has an axis of rotation (see Y, figure 1) and the suction motor axis of rotation is substantially parallel to the cyclone axis of rotation (see figure 1); and, (e) a pistol grip handle (18, figure 1) located at the rear end of the hand vacuum cleaner, wherein a finger gap area (see annotated figure below) is positioned forward of the pistol grip handle (18, figure 1) and rearward of the suction motor, (f) an energy storage unit (9, figure 1) wherein, when the hand vacuum cleaner is oriented with the cyclone axis of rotation extending horizontally and the dirty air inlet above the cyclone and wherein the pistol grip handle has a hand grip portion (10, figure 1) having a first end, a second end and a hand grip portion axis (see annotated figure below) that extends centrally through the hand grip portion from the first end of the hand grip portion to the second end of the hand grip portion, wherein both the first end of the hand grip portion and the second end of the hand grip portion are positioned rearward of the suction motor (6, figure 1), and wherein, when the upper end is above the lower end, the inlet conduit (15, figure 1) at least partially overlies the cyclone assembly. Kamimura fails to teach a pre-motor filter located between the cyclone and the suction motor, the pre- motor filter is positioned below the conduit axis. Conrad teaches a hand vacuum cleaner (abstract) that includes a cyclone (814, figure 8) and a pre-motor (862, figure 8; para 0079-0080,0095) filter comprise a removable air treatment unit (see Conrad para 0015,0019,0088,0095), a pre motor (862, figure 8; para 0095) filter located between cyclone (814, figure 8) and suction motor (864, figure 8), and a removable air treatment unit (see Conrad para 0015,0019,0088,0095) It would have been obvious to one of ordinary skill in the art before effective filing date of the claimed invention to have modified Kamimura to include wherein a pre motor filter located between cyclone and suction motor, a removable air treatment unit based on the teachings of Conrad. This modification would help increase the cleaning efficiency of the cleaning apparatus and help further filter and remove debris from the air and allow for simple maintenance to be performed. (see Conrad’s para 0019, 0054-0055,0079-0080,00888 0095) Kamimura as modified in claim 19 further in view of Conrad would disclose the pre- motor filter (see Conrad 862, figure 8) is positioned below the conduit axis (see Kamimura A, figure 1). Kamimura in view of Conrad fails to teach wherein a portion of the energy storage unit immediately underlies the suction motor and located at the lower end of the pistol grip handle. Yamada teaches a handheld vacuum cleaner (2, figures 1-3) that includes an energy storage unit (20, figure 2) is located at the lower end of the pistol grip handle (8, figure 2),a lid (9, figure 2) that protects the energy storage unit ,and wherein a portion of the energy storage unit (20, figure 2) immediately underlies the suction motor (16, figure 2). It would have been obvious to one of ordinary skill in the art before effective filing date of the claimed invention to have further modified Kamimura to have an energy storage unit is located at the lower end of the pistol grip handle that underlies the suction motor based on the teachings of Yamada. This modification would ensure the cleaner is a user-friendly handheld cleaner that allows for the energy storage unit to be easily removed and be protected from external impacts when stored on the cleaner (see Yamada pages 2-8). Kamimura in view of Conrad and Yamada fails to teach wherein the hand vacuum cleaner further comprises a removable portion that is removable from a stationary portion, the removable portion comprises at least the cyclone assembly and the stationary portion comprises at least the inlet conduit. Ohara teaches a hand vacuum that includes a wherein the inlet conduit (25, figure 1) is provided with an electrical connector (29, figure 1) and wherein the hand vacuum cleaner further comprises a removable portion (see annotated figure; “ dust collecting case 32 to which a filter body 31 is attached is engaged with a locking portion 34 of the main body 20 at an engaging portion 33”) that is removable from a stationary portion (20, figure 1) the removable portion comprises at least a cyclone assembly (“It is a so-called cyclone system that descends, so that the adhesion of dust to the filter body 31 can be reduced.”) and the stationary portion comprises at least the inlet conduit (25, figure 1). PNG media_image3.png 634 846 media_image3.png Greyscale It would have been obvious to one of ordinary skill in the art before effective filing date of the claimed invention to have further modified Kamimura to include wherein the hand vacuum cleaner further comprises a removable portion that is removable from a stationary portion, the removable portion comprises at least the cyclone assembly and the stationary portion comprises at least the inlet conduit based on the teachings of Ohara. This modification would help allow easily empty contents collected and provide maintenance to the cyclone assembly. (see abstract, pages 1-6 of Ohara). Regarding claim 20, Kamimura as modified in claim 19 wherein the cyclone assembly (see Ohara “detachable” and Conrad para 0088,0095), and the pre-motor filter comprise a removable air treatment unit. (see Conrad para 0015,0019,0088,0095). Response to Arguments Applicant’s arguments see filed 06-22-2026, with respect to the rejection(s) of claim(s) 1 and 19 their dependent claims under 35 U.S.C.103 have been fully considered but are moot because the new ground of rejection (as necessitated by amendment) relies on a different combination of prior art references, not applied in the prior rejection of record to teach the new limitations.
