Office Action

§103
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 . Response to Arguments This office action is responsive to Request for Reconsideration files on . As directed by the amendment: claims 1 – 20 are pending, no claims were cancelled, claim 21 has been added & claims 1 – 20 have been amended. Applicant’s arguments, see Page 10, filed 02/06/2026, with respect to claim objections have been fully considered and are persuasive. The objections of the claims have been withdrawn. Applicant's arguments filed 02/06/2026 have been fully considered but they are not persuasive. The amendment added to claim 1 “a distance between the third support member and the first support member and a distance between the first support member and the second support member are both longer than a distance between the first support member and the second support member” was not considered at the time of the rejection. However, Howard provided permission for the support members to be provided in any configuration. (Column 11, lines 45 – 58) Because the art provided permission, it would be well in the skill in the art to move them at different distances to provide support and it does teach it can move them for the needs of the device. Applicant's arguments filed 02/06/2026 have been fully considered but they are not persuasive. Applicant argues Howard does not expressly disclose the limitation and it relies on a broad teaching with encompasses, but does not specifically disclose the claimed embodiment. However, Howard provides permission for the support members to be added in any configuration (Column 11, lines 45 – 58) and it would be well in the skill in the art to move the support members at different distances to provide support as it teaches it can move them for the needs of the device. 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) 1 – 21 are rejected under 35 U.S.C. 103 as being unpatentable by Hoffman et al. US 8427020 B2. Regarding claim 1, A continuous positive airway pressure device, comprising: a main body case 120 (Column 5, last paragraph); a blower 10 housed inside the main body case 120 (Column 5, last paragraph); and three or more support members 108 interposed between the main body case 120 and the blower 10, and configured to support the blower 10 inside the main body case 120 (Column 6, First Paragraph), wherein the blower 10 includes a fan unit housing 12 a fan 56 configured to send air by being rotated (Column 8, Paragraph 3, lines 32 – 34), and a delivery tube 22 through which the air sent from the fan 56 passes (Column 6, lines 52 – 54), and in a view from a direction of a rotation axis of the fan 56 (see annotated Figure 5), first and second support members 108 (see annotated Figure 5) of the support members 108 are disposed to pinch the blower 10 on a side of a connection point (see annotated Figure 5.2 / Note: the examiner considers the connection point to be found between the fan unit and the delivery tube) to be between the fan unit 56 and the delivery tube 22 relative to the rotation axis (Figure 5), and a third support member 108 (see annotated Figure 5) different from the first and second support members (see annotated Figure 5) of the support members 108 is disposed on a side opposite to the connection point relative to the rotation axis Figure 5). Modified Hoffman does not expressly disclose a distance between the third support member and the first support member and a distance between the third support member and the second support member are both longer than a distance between the first support member and the second support member. However, it does disclose the support members 108 can be provided in any configuration. (Column 11, lines 45 – 58) It would have been prima facie obvious to one of ordinary skill in the art prior to the effective filling date to further modify Hoffman to have the support members 108 be provided in any configuration in order to effectively support the blower assembly while attenuating or dampening vibrations such as radial and/or axial vibration generated by the rotation of the fan. (Column 11, lines 45 – 58) It would be well in the skill in the art to move the support members at different distances to provide support as it teaches it can move them for the needs of the device.
