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 . Claim (s) 6 , 9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sorimoto (US 20180243960) . Regarding Claim 6 Sorimoto discloses that innerlock member-31 and the inner holder-22 are all configured and slidable engagemenet with each other (Figures 4-5, ) but didn’t clearly state that -wherein the interlock member and the inner holder are configured to be movable at the same timings, at the same speeds, and for the same distances . However, it’s obvious for one ordinary skilled in the art to interpret that as disclosed inner hiolder-22 is disposed and align ed with the sliding piece -21 in the movement direction of the holder - 20 and is accommodated within the holder -20 together with the sliding piece - 21 (Figure 4, [0065]) the n all the components will movable at the same timings, at the same speeds, and for the same distances . Regarding Claim 9 Sorimoto discloses holder-20 fixed at a bottom surface thereof to the distal end of the holder ejector pin - 12 so as to be reciprocatable in the demolding direction of the molded product P in conjunction with the ejector base plates ([0055]) but didn’t explicit i n place of the outer holder, a guide piece in slidable engagement with the slider . Therefore, it would be obvious for one ordinary skilled in the art to interpret that , the ejector pin-12 which is attached to the outer holder-20 will also be in slidable engagement with the slider-21 and the a guiding section i .e the ejector base plate-110 configured to guide the slider along the predetermined direction ( [0055] ) . Allowable Subject Matter The following is a statement of reasons for the indication of allowable subject matter: Regarding Claim 8 Sorimato discloses wherein the interlock member and the inner holder are configured to move together in an interlocking manner up to a predefined first point, and once the first point is reached ( inner hiolder-22 is disposed and align ed with the sliding piece -21 in the movement direction of the holder - 20 and is accommodated within the holder -20 together with the sliding piece - 21 ),. However prior art did not disclose that the interlock member and the inner holder are configured to move relatively at different speeds or the interlock member is configured to be stopped while only the inner holder is configured to be able to further move. Regarding Claim 22 Sorimato discloses wherein the carrier piece and the inner holder are configured to move together in an interlocking manner in the demolding direction of the molded article ( Figure 5, inner holder-22 and the carrier piece-35 moves in the direction of the holder i.e. the direction of the molded article [0065], [0070] ) but did not disclose that and once the second slide piece decouples from the second undercut portion, the carrier piece and the inner holder are configured to move in the demolding direction of the molded article relatively at different speeds or the carrier piece is configured to be stopped while only the inner holder is configured to be able to further move in the demolding direction of the molded article.
