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.
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
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.
Claim(s) 1-3, 6-9, and 14-15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Tokuda et al. U.S. Patent Publication Number US20200305280A1(hereinafter Tokuda) in view of Printed Circuits Handbook 6th Edition by Clyde Coombs (Author), Happy Holden (Author) September 19, 2007 ISBN-10, 9780071467346 (hereinafter Coombs).
Regarding Claim 1, Tokuda discloses A disk device comprising: an electronic component (Fig.i.e., flexure 41; para. [0038] i.e., flexure 41); a flexible printed circuit board having a first surface facing the electronic component (Fig. 2, i.e., FPC unit 50, a portion of the FPC unit facing the flexure; para. [0041] i.e., the FPC unit 50 ), a second surface located opposite to the first surface (Fig. 2, i.e., FPC unit 50, the surface opposite the first surface), and a pad provided on the first surface (Fig. 9 i.e., connection pads 61) and connected to the electronic component by a conductive adhesive (Fig. 7 i.e., solder 44; para. [0040] i.e., …the plurality of wirings of the flexure 41 extend over substantially the entire length of the flexure 41. One end of the wiring is electrically connected … is connected to the connection terminal (connection pad) 43… A solder 44 is formed on the connection terminal 43.; para. [0051] i.e., The flexible printed wiring board further includes a second conductive layer …by an adhesive layer 68 ); a first adhesive provided on the second surface (para. [0041] The flexible printed wiring board (FPC) is configured as a multilayer…); a plate having a third surface facing the second surface (Fig. 2, i.e., reinforcing plate 54, The portion of the reinforcing plate 54 facing opposite the flexure; para. [0042] i.e., reinforcing plate 54 ) but Tokuda fails to explicitly disclose the specific configuration in which a first adhesive provided on the second surface and a first bonding layer provided on the third surface, entering a recess of the third surface, and fixed to the second surface by the first adhesive.
In an analogous art, Coombs teaches a first adhesive provided on the second surface (pages 61.7-61.8, 61.3.2 Applications, i.e., … specially developed high-density flexible circuits can provide highly reliable connections at a low cost for new tiny magnetic heads of hard disk drives with a vertical recording system; pages 61.8, 61.4.1 Traditional Flexible Circuit Materials, i.e., adhesive layer); a first bonding layer provided on the third surface (page G.1 i.e., bonding layer and page 65.1-65.5, Table 65.1 i.e., Bonding sheets), entering a recess of the third surface (page. 11.3, 11.2.2.2 Oxide and Oxide Alternative Processes. i.e., During PCB fabrication, the internal copper surfaces are generally chemically treated to improve the adhesion between the resin system and the copper layer. … These processes generally use etching chemistries, which also roughen the copper surface to provide greater surface area for resin bonding, and often use proprietary chemistries designed to further enhance adhesion and chemical resistance.; pages 65.1-65.5, FIGURE 65.6 i.e., Pattern Etching of Outer Layers), and fixed to the second surface by the first adhesive (page. 61.8, 61.4.1 Traditional Flexible Circuit Materials, i.e., adhesive layer).
Although Coombs does not teach explicitly the specific configuration of the multiple adhesive layers and bonding layers arranged in a chosen order, it would have been obvious to one having ordinary skill in the art to try various orders, including the claimed order, using well-known and conventional adhesive and bonding techniques. A person of ordinary skill in the art, upon reading the Coombs Reference, would also have recognized the desirability of improved methods of bonding a plate to a flexible printed circuit board. Coombs teaches various flexible circuit board designs having a finite number of adhesive layers and bonding layers suitable for use in a hard disk drive. Thus, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have pursued the known options within his or her technical grasp and thus bond a plate reliably to a flexible printed circuit board as claimed.
Regarding Claim 2, Tokuda as modified by Coombs discloses the disk device as discussed in claim 1. Tokuda further comprising :

[0027] i.e., A plurality of magnetic heads 31 which record and read information on and from the magnetic disks 21…) ; and a carriage configured to rotate to move the magnetic head (para. [0027] i.e., actuator assembly (carriage assembly) 32 which movably supports these magnetic heads 31 with respect to the magnetic disks 21 are provided in the housing 10. In addition, a voice coil motor (hereinafter referred to as a VCM) 33 which rotates and positions the actuator assembly 32…), wherein the electronic component has a flexure that is connected to the pad by the joint body (Fig. 2 and Fig. 3, A flexure is connected to a pad 61.; para. [0040] i.e., A plurality of connection terminals (connection pads) 43 are provided in the connection end portion 42. The connection terminals 43 are respectively connected to the wirings of the flexure 41 ) and electrically connects the flexible printed circuit board and the magnetic head (Fig. 2 and Fig. 3; para. [0029] i.e., The printed circuit board constitutes a control unit, and the control unit controls the operation of the spindle motor 22 and also controls the operations of the VCM 33 and the magnetic head 31 via the FPC unit 50; para. [0049] i.e., the bonding portion 53 of the FPC includes fourteen connection pad groups corresponding to the connection end portions 42 of the suspension assembly…), and the plate is attached to the carriage (Fig. 2 and Fig. 3, The relay portion 52 of FPC and the bonding portion 53 of FPC are attached to an actuator assembly 32. ; para.
