Claim Rejections - 35 USC § 103
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 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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.

Regarding Claims 5 and 20, Mouri, as modified, teaches the substrate treating apparatus (substrate cleaning apparatus, 1) of claims 4 and 19, as discussed above.
Mouri does not teach the contact protrusion protrudes from the bottom of the groove portion to flush with a bottom surface of the contact pad or less than thereof; however, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Mouri to further include the contact protrusion protrudes from the bottom of the groove portion to flush with a bottom surface of the contact pad or less than thereof, as claimed, since it has been held that rearranging parts of an invention involves only routine skill in the art (MPEP 2144.04 VI).
Regarding Claim 6, Mouri, as modified, teaches the substrate treating apparatus (substrate cleaning apparatus, 1) of claim 4, as discussed above.
Mouri does not teach the plurality of contact protrusions in each groove portion are grouped into a plurality of groups with a distance between adjacent groups being greater than a distance between adjacent contact protrusion in each group, at least one group of the contact protrusions is positioned near the center of the body, and at least one group of the contact protrusion is positioned near the edge of the body; however, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Mouri to further include the plurality of contact protrusions in each groove portion are grouped into a plurality of groups with a distance between adjacent groups being greater than a distance between adjacent contact protrusion in each group, at least one group of the contact protrusions is positioned near the center of the body, and at least one group of the contact protrusion is positioned near the edge of the body, as claimed, since it has been held that rearranging parts of an invention involves only routine skill in the art (MPEP 2144.04 VI).

Mouri embodiment of Fig. 8 does not explicitly teach a plurality of contact pads protruding from a bottom of the body, however, Mouri teaches an embodiment as shown in Fig. 13 wherein a plurality of contact pads (21c’) protruding from a bottom of the body (23).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Mouri to further a plurality of contact pads protruding from a bottom of the body, as claimed, since it has been held that rearranging parts of an invention involves only routine skill in the art (MPEP 2144.04 VI).
Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Mouri et al (U. S. Patent Publication No. 2009-0313776 A1) in view of Choi (KR20100060680 A).
Regarding Claim 7, Mouri, as modified, teaches the substrate treating apparatus (substrate cleaning apparatus, 1) of claim 4, as discussed above.
Mouri does not teach a bottom end of the plurality of contact protrusion is convex.
Choi, however, teaches the substrate treating apparatus (single wafer polishing system, Fig. 3) wherein a bottom end of the plurality of contact protrusion (613b) is convex (Fig. 15).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Mouri to further include a bottom end of the contact protrusion is convex as taught by Choi, since such a modification would have involved a mere change in the shape of a component. A change in shape is generally recognized as being within the level of ordinary skill in the art. (MPEP 2144.04 IV B).
Claims 13 – 14 are rejected under 35 U.S.C. 103 as being unpatentable over Mouri et al (U. S. Patent Publication No. 2009/0313776 A1) in view of Kurusu (U. S. Patent Publication No. 2013/0206171 A1).

Mouri does not teach an arm for supporting the cleaning nozzle.
Kurusu, however, teaches an arm (41) for supporting the cleaning nozzle (cleaning nozzle, 42; Paragraph [0058]).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the apparatus of Mouri to further include an arm for supporting the cleaning nozzle, as taught by Kurusu, since it has been held that rearranging parts of an invention involves only routine skill in the art (MPEP 2144.04 VI).
