See paragraph [0196] . PNG media_image1.png 420 486 media_image1.png Greyscale Claim Rejections - 35 USC § 103 07-20-aia AIA 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. 07-23-aia AIA 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. 07-21-aia AIA Claim (s) 14 is/are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent Publication Number 2017/0231756 (Armer et al.) in view of U.S. Patent Publication Number 2012/0059458 (Buchbinder et al.) Regarding claim 14, Armer et al. fails to disclose wherein an axial midpoint of the waist portion is concave. Buchbinder et al., from the same field of endeavor teaches a similar expandable frame as shown in Figure 1B and Figure 6, wherein an axial midpoint of the waist portion is concave. It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to modify the shape of the axial midpoint disclosed by Armer et al. for the shape of the midpoint taught by Buchbinder et al. because it would only require the simple substitution of one known alternative for another to produce nothing but predictable results. See KSR International Co. v. Teleflex Inc. , 550 U.S. 398, 82, USPQ2d 1385 (2007) . 07-21-aia AIA Claim (s) 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent Publication Number 2017/0231756 (Armer et al.) in view of U.S. Patent Publication Number 20020058989 (Chen et al.) Regarding claim 18, Armer et al. fails to disclose wherein the central strut portions have a cross-sectional area greater than a cross-sectional area of the first and second end strut portions. Chen et al., from the same field of endeavor teaches a similar expandable frame as shown in Figure 9, where the central strut portions have a cross-sectional area greater than a cross-sectional area of the first and second end strut portions for the purpose of increasing the strength of the central strut portion. See paragraph [0027]. It would have been obvious to one ordinary skill in the art, before the effective filing date of the claimed invention to modify the central strut portions have a cross-sectional area greater than a cross-sectional area of the first and second end strut portions in order to configure the central strut portions to be stronger . 07-21-aia AIA Claim (s) 22 is/are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent Publication Number 2017/0231756 (Armer et al.) in view of U.S. Patent Publication Number 2007/0043435 (Seguin et al.) Regarding claim 22, Armer et al. fails to disclose wherein the first major lateral dimension is approximately 50 mm. Seguin et al., from the same field of endeavor teaches a similar expandable frame as shown in Figure 9, wherein the first major lateral dimension is approximately 50 mm. See paragraph [0208]. It would have been obvious to one ordinary skill in the art, before the effective filing date of the claimed invention to modify the first major lateral dimension by substituting the size of the first major lateral dimension disclosed by Armer for the size of the first major lateral dimension taught by Seguin such that the first major lateral dimension is approximately 50 mm because it would only require the simple substitution of one known alternative for another to produce nothing but predictable results. See KSR International Co. v. Teleflex Inc., 550 U.S. 398, 82, USPQ2d 1385 (2007) . 07-21-aia AIA Claim (s) 23 is/are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent Publication Number 2017/0231756 (Armer et al.) in view of U.S. Patent Publication Number 2013/0253642 (Brecker) Regarding claim 23, Armer et al. fails to disclose wherein the third major lateral dimension is approximately 27 mm. Brecker, from the same field of endeavor teaches a similar expandable frame as shown in Figure 9, wherein the third major lateral dimension is approximately 27 mm. See paragraph [0016]. It would have been obvious to one ordinary skill in the art, before the effective filing date of the claimed invention to modify the third major lateral dimension by substituting the size of the third major lateral dimension disclosed by Armer for the size of the Third major lateral dimension taught by Brecker such that the first major lateral dimension is approximately 27 mm because it would only require the simple substitution of one known alternative for another to produce nothing but predictable results. See KSR International Co. v. Teleflex Inc., 550 U.S. 398, 82, USPQ2d 1385 (2007) . 07-21-aia AIA Claim (s) 24 , is/are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent Publication Number 2017/0231756 (Armer et al.) in view of U.S. Patent Publication Number 2009/0222082 (Lock et al.) Regarding claim 24, Armer et al. fails to disclose at least one radiopaque marker attached to the frame. Lock et al., from the same filed of endeavor teaches a similar expandable frame as shown in Figure 1, where at least one radiopaque marker attached to the frame for the purpose of facilitating a determination of the expanded size of the frame. See paragraph [0013]. It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to include at least one radiopaque marker attached to the frame in order to of facilitate a determination of the expanded size of the frame . 07-22-aia AIA Claim (s) 25 is/are rejected under 35 U.S.C. 103 as being unpatentable over U.S. Patent Publication Number 2017/0231756 (Armer et al.) in view of U.S. Patent Publication Number 2013/0253642 (Brecker) as applied to claim 23 above, and further in view of U.S. Patent Publication Number 2009/0222082 (Lock et al.) . Regarding claim 25, Armer et al. fails to disclose wherein the at least one radiopaque marker is attached to the waist portion of the frame. Lock et al., from the same filed of endeavor teaches a similar expandable frame as shown in Figure 1, where at least one radiopaque marker attached to the frame for the purpose of facilitating a determination of the expanded size of the frame. See paragraph [0013]. It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to include at least one radiopaque marker attached to the frame in order to of facilitate a determination of the expanded size of the frame. It would have been further obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to modify the frame by attaching the marker to the waist portion of the frame because it would only require the rearrangement of parts without changing how the device operates. See In re Japikse , 181 F.2d 1019, 86 USPQ 70 (CCPA 1950) Response to Arguments 07-38-01 AIA Applicant’s arguments, see page 6 , filed 03/04/2026 , with respect to the rejection of claim 25 under 35 USC 112, second paragraph have been fully considered and are persuasive. The rejection of claim 25 under 35 USC 112, second paragraph has been withdrawn. Applicant’s arguments, see pages 6-8, filed 03/04/2026, with respect to the rejection of claims 1-13, 15-17, 19-21 under Armer et al. have been considered but are not persuasive. The applicant argues Armer fails to disclose wherein at least one of the first apices and the second apices are contoured radially inward. In response, the Office respectfully disagrees. While it is true Armer discloses retaining portions have an outward flare, the claims do not limit the “contoured radially inward” to retaining portions. Claim 1 broadly encompasses first apices and second apices . In this case, the non-retaining apices (generally indicated as A) as clearly shown to be contoured radially inward: PNG media_image1.png 420 486 media_image1.png Greyscale Conclusion 07-40 AIA Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action.
