DETAILED ACTION
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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 8/31/2026 has been entered.
Response to Arguments
Applicant’s arguments, filed 8/31/2026, with respect to the 103 rejections of claim 1-20 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of amendments to claims 1, 10, and 19.
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.
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.
Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Shiba (CN 105284195 A) in view of Ono et. al (JP 2004055892 A) hereafter referred to as Ono and further in view of Chang et. al (US 20040034994 A1) hereafter referred to as Chang.
Regarding claim 1, Shiba teaches a top-mount printed circuit board (PCB) mounting assembly, comprising:
a PCB (unnumbered circuit board disposed on 34 control board, pg 6 ¶5) with a top surface as a reference surface (pg 6 ¶5, surface 34 control board is mounted on);
a chassis (12 PCU casing) disposed underneath the PCB and separate from the PCB (Fig 1, 12 PCU and 34 control board are separated by 18 nut);
a shoulder screw (22 bolt) comprising
a screw head (25 head and 24 flange),
a screw body (26 middle part) and
a screw tail (26 middle part), and
a nut (18 nut),
positioned between the PCB and the chassis (Pg 11 Fig 2A),
made of a rigid feature (pg 4 ¶10, 18 nut is made of metal), and
configured to receive and fasten the shoulder screw (pg 4 ¶10, Fig 2A) and keep a distance between the PCB and the chassis within a controlled dimension (Fig 2A).
Shiba fails to teach the shoulder screw is soldered on a top of the PCB. However, Ono teaches the shoulder screw (3 screw) is soldered on a top of the PCB (1 circuit board, ¶7 solder is applied to the screw connected to the circuit board 1). Shiba and Ono are both in the industry of fasteners to circuit boards therefore it would have been obvious to a person having ordinary skill in the art to solder the screw to the circuit board in order to minimize the creep phenomenon and stay attached securely (Ono ¶7)
Shiba in view of Ono fails to teach the shoulder screw has a screw tail and is connected to the chassis by tightening a screw from a bottom of the chassis, wherein the shoulder screw tail comprises a hollow interior, and wherein the screw extends from the bottom of the chassis into the hollow interior of the shoulder screw tail to fasten the shoulder screw to the nut.
However, Chang teaches the shoulder screw (1 shaft) has a screw tail (12 post) and is connected to the chassis (8 PCB) by tightening a screw (7 screw) from a bottom of the chassis (100 shell, Fig 6) wherein the shoulder screw tail comprises a hollow interior (Fig 5), and wherein the screw extends from the bottom of the chassis (100 shell) into the hollow interior of the shoulder screw tail to fasten the to fasten the shoulder screw to the nut (3fixing pillar) (Fig 6). Shiba, Ono, and Chang are all in the industry of fasteners for circuit boards therefore it would have been obvious to a person having ordinary skill in the art to modify the teachings of Shiba and Ono to include the screw member structure of Chang in order to provide a grounding effect and prevent electromagnetic interference and vibrations from damaging the PCB (Chang abstract and ¶35)
Regarding claim 2, Shiba in view of Ono and further in view of Chang teach the top-mount PCB mounting assembly of claim 1, wherein the screw body (26 middle part) comprises a first screw body part (see annotated Fig 2A below) connected with the screw head (25 head and 24 flange) and a second screw body part (see annotated Fig 2A below).
