Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Double Patenting
Claim(s) 1-12 of this application is/are patentably indistinct from claim(s) 1-12 of Application No. 18/350,605. Pursuant to 37 CFR 1.78(f), when two or more applications filed by the same applicant or assignee contain patentably indistinct claims, elimination of such claims from all but one application may be required in the absence of good and sufficient reason for their retention during pendency in more than one application. Applicant is required to either cancel the patentably indistinct claims from all but one application or maintain a clear line of demarcation between the applications. See MPEP § 822.
A rejection based on double patenting of the “same invention” type finds its support in the language of 35 U.S.C. 101 which states that “whoever invents or discovers any new and useful process... may obtain a patent therefor...” (Emphasis added). Thus, the term “same invention,” in this context, means an invention drawn to identical subject matter. See Miller v. Eagle Mfg. Co., 151 U.S. 186 (1894); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Ockert, 245 F.2d 467, 114 USPQ 330 (CCPA 1957).
A statutory type (35 U.S.C. 101) double patenting rejection can be overcome by canceling or amending the claims that are directed to the same invention so they are no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101.
Claim(s) 1-12 is/are provisionally rejected under 35 U.S.C. 101 as claiming the same invention as that of claim 1-12 of co-pending Application No. 18/350,605 (reference application). This is a provisional statutory double patenting rejection since the claims directed to the same invention have not in fact been patented.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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.

Claim(s) 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sekretta (US 9879708 B2) in view of Sawai (KR 101432416 B1), further in view of Andresen (WO 2018177886 A1).
Regarding claim 19, Sekretta, in view of Sawai and Andresen, disclose the latching mechanism as claimed in claim 18.
Sekretta, as modified by Sawai and Andresen, fails to disclose a latching mechanism further including a base member, said base member being attached to the bottom of said latch housing, and said base member comprising a base member arm for each of the latch fingers, and each of said base member arms including a limit spring, each of said base member arms and said limit spring being positioned under said associated latch finger, and each of said limit springs being configured to compress in response to said associated latch finger pivoting to a predefined open position and limit further pivoting of said associated latch finger.
However, Ottomanelli teaches a latching mechanism further including a base member, said base member being attached to the bottom of said latch housing, and said base member comprising a base member arm for each of the latch fingers, and each of said base member arms including a limit spring, each of said base member arms and said limit spring being positioned under said associated latch finger, and each of said limit springs being configured to compress in response to said associated latch finger pivoting to a predefined open position and limit further pivoting of said associated latch finger (see Para. 0050 and Figs. 8-11).
Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to introduce further including a base member, said base member being attached to the bottom of said latch housing, and said base member comprising a base member arm for each of the latch fingers, and each of said base member arms including a limit spring, each of said base member arms and said limit spring being positioned under said associated latch finger, and each of said limit springs being configured to compress in response to said associated latch finger pivoting to a predefined open position and limit further pivoting of said associated latch finger, on the latching mechanism of Sekretta, as modified by Andresen, as taught by Ottomanelli, in order to provide a biasing force acting on a surface of latch release lever (see Para. 0050).
Regarding claim 20, Sekretta, in view of Sawai, Andresen and Ottomanelli, discloses the latching mechanism as claimed in claim 14, wherein Andresen further discloses wherein said block spring is configured to push said sliding block to a third position outside of said latch fingers, and said latch fingers being biased to a closed position, and in said closed position said latch fingers providing a support surface for supporting said sliding block and said bullet assembly (see Page 19, Para. 7 for the damping spring).
Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to introduce wherein said block spring is configured to push said sliding block to a third position outside of said latch fingers, and said latch fingers being biased to a closed position, and in said closed position said latch fingers providing a support surface for supporting said sliding block and said bullet assembly, on the latching device of Sekretta, as taught by Andresen, in order to damp mechanical components during lifting load (see Page 19, Para. 7).
