Claim Rejections - 35 USC § 103
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.

Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify the first plurality material section and the second plurality material section of Stern so that the first plurality of adjacent material sections is different from the second plurality of adjacent material sections as taught by Palmer for the purpose of capability of changing the stiffness (Palmer, ¶0198).
Re Claim 2, Stern fails to disclose wherein in the first region the reinforcement material section comprises a first structural dimension and in the second region the reinforcement material section comprises a second structural dimension different than the first structural dimension.
However, Gilmartin discloses a medical tube (Fig, 1-2a) comprise a reinforcement material (22, Fig. 1) and plurality of material ( 14, 18, 20) has in the first region ( left section) the reinforcement material section comprises a first structural dimension (width, ¶0020) and in the second region ( right portion ) the reinforcement material section comprises a second structural dimension different than the first structural dimension (width ¶0020, wherein the width of the strap can changes to change the flexibility/stiffness, ¶0034).
Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify the reinforcement material section of Stern so that in the first region the reinforcement material section comprises a first structural dimension and in the second region the reinforcement material section comprises a second structural dimension different than the first structural dimension. as taught by Gilmartin for the purpose of having tubular member with a desired of degree stiffness (Gilmartin, ¶0020).
Re Claim 3, Stern discloses wherein the first hardness is greater than a respective hardness of each of the first plurality of adjacent material sections (stainless steel is harder than nitinol, ¶0170).
Re Claim 4, Stern discloses wherein the second hardness is greater than a respective hardness of each of the second plurality of adjacent material sections (stainless steel is harder than nitinol, ¶0170, wherein 20b include steel can be made from a material harder than 20a which may include steel , or nitinol).
Re Claim 5, Stern discloses further comprising an inner liner that is interior to the tubular body (22, ¶0152).
Re Claim 6, Stern discloses further comprising a reinforcement structure is exterior to the inner liner (Fig. 3b).
Re Claim 7, Stern discloses wherein the reinforcement structure is embedded within the wall (28, Fig. 3b).
Re Claim 8, Stern discloses wherein the plurality of material sections extends in in a right-hand wind direction in the first region (¶0156).
Re Claim 9, Stern discloses wherein the plurality of material sections extends in in a left-hand wind direction in the first region (¶0156, if the point of view from proximal end).
Re Claim 10, Stern discloses wherein at least one of the plurality of material sections comprises a non-fusable material (¶0170).
Re Claim 11, Stern discloses further comprising a soft distal tip section (12b,¶0164, distal portion is more flexible than the other portion, ¶00192).
Re Claim 29, Stern discloses wherein the wall is an exterior wall of both the first region and second region of the tubular body (24, 28 are the exterior wall).

However, Takagi disclose a catheter (Fig.4) and wherein the soft distal tip section comprises a single material (4, Fig. 1, ¶0067-¶0068).
Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify the reinforcement material section of Stern so that the soft distal tip section comprises a single material as taught by Takagi for the purpose of having tubular member with a desired tip with flexibility from an art recognized material (Takagi, ¶0067-¶0068).
Claim(s) 26 is/are rejected under 35 U.S.C. 103 as being unpatentable over Stern in view of Wada (US. 20190134348A1).
Re Claim 26, Stern discloses wherein the tubular body comprises a proximal region located (17a) proximally to both the first region and the second region (Fig. 1), but it fails to disclose that the proximal region comprising a single material.
However, Wada disclose a catheter (Fig.1-3) and wherein the tubular body comprises a proximal region (14c, Fig. 3 at line -e-) located proximally to both the first region (region at line -d- )and the second region (region at line -c-) , the proximal region comprising a single material (Fig. 3, ¶0037, ¶0051).

Response to Arguments
Applicant's arguments filed 3/23/2026 with respect to claims 14 have been fully considered but they are not persuasive. The applicant argues that Stern fails to discloses a first region has a first polymer that comprises a first hardness and a second region comprises a second polymer comprises a second hardness. This is found not persuasive as Stern discloses 1a-b. 20a-b are polymer and may include nitinol and steel see ¶0160-¶0161 and ¶0170.
Applicant’s arguments, see remark, filed 3/23/2026, with respect to the rejection(s) of claim(s) 1 under 103 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 over Stern in view of and Plamer.
