`
`DETAILED ACTION
`
`1.
`
`The present application is being examined under the pre-AIA first to invent
`
`provisions.
`
`Response to Amendment
`
`2.
`
`Claims 1 and 5 have been amended to include a new limitation. No new matter
`
`issues have arisen as a result of these changes.
`
`Claim Rejections - 35 USC § 103
`
`3.
`
`The following is a quotation of pre-AIA 35 U.S.C. 103(a) which forms the basis
`
`for all obviousness rejections set forth in this Office action:
`
`(a) A patent may not be obtained though the invention is not identically disclosed or described
`as set forth in section 102 of this title, if the differences between the subject matter sought to
`be patented and the prior art are such that the subject matter as a whole would have been
`obvious at the time the invention was made to a person having ordinary skill in the art to which
`said subject matter pertains. Patentability shall not be negatived by the manner in which the
`invention was made.
`
`4.
`
`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 pre-AIA 35 U.S.C. 103(a) 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.
`
`5.
`
`Claims 1, 2 and 7 are rejected under pre-AIA 35 U.S.C. 102(b) as being
`
`anticipated by Cho (US PG Pub 2007/0025864) in view of Ohtahara et al. (herein
`
`

`

`Application/Control Number: 15/168,912
`
`Page 3
`
`Art Unit: 3746
`
`Ohtahara) (US PG Pub 2008/0304994)
`
`Regarding Claim 1:
`
`In Figures 1-4, Cho discloses a sealed compressor comprising: an electric component
`
`(drive unit, see paragraph [0017]) including a stator (12) and a rotor (13); a compression
`
`component (compression unit, see paragraph [0017]) actuated by the electric
`
`component (see paragraph [0019]); and a sealed container (hermetic container 10)
`
`accommodating the electric component and the compression component and storing
`
`lubricating oil (oil in oil sump 19) for lubricating the compression component (as seen in
`
`Figure 1 and paragraph [0022]); wherein the compression component includes a shaft
`
`(20) including a main shaft section (21) to which the rotor (13) is fastened (see Figure 1)
`
`and an eccentric shaft section (22), a cylinder block (14) accommodating a piston (15)
`
`reciprocatable according to rotation of the shaft (see paragraph [0027]), a main bearing
`
`unit
`
`(portion of frame 11 depicted as 10c in Figure 1) mounted on the cylinder block
`
`(14) to support the main shaft section (21), and a thrust ball bearing (thrust bearing 30,
`
`see Figure 2) disposed between a flange surface (flange surface located below
`
`eccentric shaft 22, henceforth referred to as FS) formed in the shaft and a thrust surface
`
`(surface of main bearing unit 10c in contact with lower race 32, henceforth referred to as
`
`T8) formed in the main bearing unit (see Figure 2); the main shaft section (21) is
`
`provided with a first oil feeding passage (oil channel array 50, see paragraph [0033]) to
`
`transport the lubricating oil from a lower portion of the main shaft section to an upper
`
`portion of the main shaft section(see paragraphs [0033]-[0034]); the thrust ball bearing
`
`(30) includes a plurality of balls (33) held in a cage (portion carrying balls 33 as seen in
`
`

`

`Application/Control Number: 15/168,912
`
`Page 4
`
`Art Unit: 3746
`
`Figure 2, henceforth referred to as C), an upper race (31) disposed such that one of its
`
`main surfaces is in contact with upper portions of the balls (as clearly seen in Figure 2);
`
`and a lower race (32) disposed such that one of its main surfaces is in contact with
`
`lower portions of the balls (as clearly seen in Figure 2); the main surface of the upper
`
`race and the main surface of the lower race face each other (as clearly seen in Figure
`
`2); at least one of the main surface of the upper race and the main surface of the lower
`
`race, the main surfaces facing each other, is provided with a raceway groove which is
`
`formed by an annular groove, and in which the balls are placed (as seen in Figure 2,
`
`both upper and lower races each have an annular raceway groove. More clearly
`
`depicted in Figure 5); and the thrust ball bearing is provided with a second oil feeding
`
`passage (passageway formed by gap between the upper and lower races and between
`
`any two adjacent balls, henceforth referred to as P2) communicated with the first oil
`
`feeding passage (branch channel 54 of first oil feeding passage 50 feeds oil directly to
`
`thrust bearing and all passages formed within said thrust bearing, see Figure 2 and
`
`paragraph [0033]) and configured to feed the lubricating oil to the raceway groove (as
`
`seen in Figure 2, the gap between the cage, the upper and lower races and any two
`
`adjacent balls is fed with lubricating oil) and a discharge passage (aforementioned gap.
`
`Also see paragraph [0038] which states that the oil used to lubricate the thrust bearing
`
`is capable of being returned to the oil sump indicating that the oil is discharged via the
`
`gap) through which the lubricating oil fed to the raceway groove is discharged to outside
`
`of the thrust ball bearing (as evident from Figure 2, the gap between the cage, the upper
`
`and lower races and any two adjacent balls is fed with lubricating oil wherein this oil is
`
`

`

`Application/Control Number: 15/168,912
`
`Page 5
`
`Art Unit: 3746
`
`discharge through this gap to the exterior of the thrust bearing 30).
`
`Cho substantially discloses all the claimed limitations but fails to disclose that the thrust
`
`surface is provided with a discharge hole to discharge the lubricating oil, wherein the
`
`discharge hole extends along an axial direction of the main shaft section.
`
`However, in Figure 1, Ohtahara discloses a similar sealed compressor wherein a thrust
`
`surface carrying a bearing (401) is provided with a discharge hole (hole formed in
`
`discharge pipe 408) such that after lubricating the bearing, the oil is discharged directly
`
`to an oil reservoir, wherein the discharge hole (in the form of discharge pipe 408) clearly
`
`extends downwards in an axial direction along a main shaft section (see paragraph
`
`[OO45D.
`
`Hence, based on Ohtahara's teachings, it would have been obvious to one of ordinary
`
`skill in the art, at the time the invention was made, to include a discharge hole (in the
`
`form of a discharge pipe as taught by Ohtahara) in Cho's thrust surface (TS) such that
`
`after lubricating Cho's thrust bearing (30), the lubricating oil could be directly guided via
`
`the discharge hole and pipe to Cho's oil sump (19), thereby minimizing oil spillage and
`
`wastage.
`
`Regarding Claim 2:
`
`ln Figures 1-4, Cho discloses a sealed compressor wherein the thrust surface (TS) is
`
`defined by an inner bottom surface of a recess formed in a main surface which is an
`
`upper surface of the main bearing unit (as seen clearly in Figure 2); and the main
`
`surface of the main bearing unit is disposed below a lower surface of the cage (also
`
`seen clearly in Figure 2).
`
`

`

`Application/Control Number: 15/168,912
`
`Page 6
`
`Art Unit: 3746
`
`Regarding Claim 7:
`
`In paragraph [0005] Cho discloses that the sealed compressor as disclosed in the
`
`rejection of claim 1, is typically used in a refrigeration unit (air conditioner or
`
`refrigerator).
`
`6.
`
`Claim 5 is rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over
`
`Cho (US PG Pub 2007/0025864) in view of Ohtahara (US PG Pub 2008/0304994) as
`
`evidenced by Kobayashi et al. (herein Kobayashi) (JP 2010-255556).
`
`Cho discloses the claimed invention except for the inner diameter of the cage being
`
`greater than the inner diameters of the upper and lower races.
`
`However, in Figure 2, Kobayashi discloses an example of thrust bearing in a similar
`
`Hermetic compressor, wherein the inner diameter of a cage (133) is larger than the
`
`respective inner diameters of each of the upper and lower races (135 and 136).
`
`Kobayashi further discloses that the inner diameter of the upper race (135) is smaller
`
`than the inner diameter of the lower race (136). Furthermore, a change of size is
`
`generally recognized as being within the level of ordinary skill in the art. In re Rose, 105
`
`USPQ 237 (CCPA 1955). Therefore, based on the evidence disclosed by Kobayashi
`
`and the cited case law, it would have been an obvious matter of choice to design Cho's
`
`cage to have an inner diameter that was greater than the inner diameters each of the
`
`upper and lower races and to also change the inner diameter of the upper race such
`
`that it was smaller than the inner diameter of the lower race, since such modifications
`
`would involve mere changes in the sizes of the components.

`
`7.
`
`Claim 6 is rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over
`
`Cho (US PG Pub 2007/0025864) in view of Ohtahara (US PG Pub 2008/0304994) in
`
`view of Akashi et al. (herein Akashi) (US Patent No. 7,832,994)
`
`Cho substantially discloses all the claimed limitations but is silent regarding whether
`
`Cho's motor is driven by an inverter unit.
`
`However, in Figure 1, Akashi discloses a similar sealed compressor with an inverter
`
`driven motor (104). This inverter is capable of driving the motor at a plurality of driving
`
`frequencies (i.e., at multiple speeds, since motor speed is directly proportional to driving
`
`frequency), including a driving frequency not greater than a power frequency (see
`
`claims 7-12 and column 9, lines 40-67).
`
`Hence based on Akashi’s teachings, it would have been obvious to one of ordinary skill
`
`in the art, at the time the invention was made, to utilize an inverter to drive Cho’s motor
`
`at various different driving frequencies, thereby allowing Cho's motor to be driven at
`
`different speeds including a low speed at a driving frequency lower than a power supply
`
`frequency and thus advantageously reduce the power consumed by Cho’s compressor
`
`(see Akashi's column 9, lines 40-67).
`
`Response to Arguments
`
`8.
`
`Applicant's arguments filed 2/14/2017 have been fully considered but they are
`
`not persuasive.
`
`9.
`
`With respect to the rejection of claim 1, applicant argues that the discharge hole
`
`(discharge pipe 408) taught by Ohtahara does not extend along an axial direction of the
`
`main shaft section. The examiner disagrees with this argument since it can be clearly
`
`

`

`Application/Control Number: 15/168,912
`
`Page 8
`
`Art Unit: 3746
`
`seen in Ohtahara's Figure 1 that the discharge hole (408) clearly extends over a large
`
`axial distance that is clearly parallel to the main shaft section (300). It should also be
`
`noted that Ohtahara’s discharge hole, at the point where it emanates from the thrust
`
`surface, has both a radial dimension and an axial dimension and so even at that point,
`
`the discharge hole would at least partially extend over a small axial distance along the
`
`main shaft section.
`
`10.
`
`The arguments regarding claim 6 are moot in view of the new grounds of
`
`rejection presented above.
`
`Conclusion
`
`11.
`
`THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time
`
`policy as set forth in 37 CFR 1.136(a).
`
`A shortened statutory period for reply to this final action is set to expire THREE
`
`MONTHS from the mailing date of this action.
`
`In the event a first reply is filed within
`
`TWO MONTHS of the mailing date of this final action and the advisory action is not
`
`mailed until after the end of the THREE-MONTH shortened statutory period, then the
`
`shortened statutory period will expire on the date the advisory action is mailed, and any
`
`extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of
`
`the advisory action.
`
`In no event, however, will the statutory period for reply expire later
`
`than SIX MONTHS from the mailing date of this final action.
