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.
Claims 1-8 are rejected under 35 U.S.C. 103 as being unpatentable over Yang et al. (US 2018/0055343; hereinafter Yang), in view of Elwood et al. (US 2018/0263799; hereinafter Elwood).
Regarding claim 1, Yang discloses a photoacoustic and ultrasonic endoscopy system. Yang teaches a helical scan photoacoustic-ultrasonic endoscope (see abstract and par. [0076]) comprising: a probe (see 200 in fig. 1; par. [0076]); and a driving unit providing rotational power and pullback translational motion to the probe (see 100 in fig. 1; par. [0076], [0127]) wherein the probe comprises: a catheter tubing extending in one direction (see catheter 220 in fig. 1; par. [0076]) and having an interior that is hollow (fig. 1 shows that catheter 220 is hollow inside), one end of the catheter tubing being closed (see distal end of catheter 220 in fig. 1 which is closed) and the other end of the catheter tubing being open (see proximal end of catheter 220 in fig. 1); a coupler that is coupled to the other end of the catheter tubing (fig. 1 shows that proximal of probe 200 is coupled to prove driving unit 100) and has a through hole corresponding to the interior of the catheter tubing (see fig. 1); a pullback shaft extending into the interior of the catheter tubing through the through hole of the coupler (see par. [0085], [0097]; fig. 1) and having an interior that is hollow (see par.

[0056], [0057]; fig. 4).
Regarding claim 6, Yang and Elwood disclose the invention substantially as described in the 103 rejection above, furthermore, Yang shows further comprising a matching fluid filling the interior of the catheter tubing (see par. p0087]).
Regarding claim 7, Yang and Elwood disclose the invention substantially as described in the 103 rejection above, furthermore, Yang shows further comprising a connector connected to an end of the pullback shaft in a direction facing away from the one end of the catheter tubing (see fig. 1 and 12).
Regarding claim 8, Yang and Elwood disclose the invention substantially as described in the 103 rejection above, furthermore, Yang shows wherein the connector is located in the direction facing away from the one end of the catheter tubing (see fig. 1 and 12), with respect to the shaft seal see par. [0037], [0085]; fig. 1).
Claims 9-10 are rejected under 35 U.S.C. 103 as being unpatentable over Yang et al. (US 2018/0055343; hereinafter Yang), in view of Elwood et al. (US 2018/0263799; hereinafter Elwood), in view of Reiter (US 2014/018765) and Courtney et al. (US 2012/0197113; hereinafter Courtney).
Regarding claim 9, Yang and Elwood disclose the invention substantially as described in the 103 rejection above, furthermore, Yang shows further comprising a coaxial cable electrically connected to the scanning tip (see par. [0096], 0107], [0161]), and extending to the connector through the interior of the torque coil (see fig. 1, 3 and 12), wherein the connector comprises: a ferrule having a central hole through which the probe-side optical fiber passes (see fig. 1, 3 and 12) and a connector housing surrounding at least a part of the ferrule (see fig. 1, 3 and 12), but fails to explicitly state wherein the connector comprises: a ferrule having a central hole through which the probe-side optical fiber passes; a connector housing surrounding at least a part of the ferrule and having electrical conductivity; a connector nut physically contacting the connector housing and having electrical conductivity; and a connector insulating member interposed between the ferrule and the connector housing to electrically insulate the ferrule from the connector housing, wherein a core part of the micro coaxial cable is electrically connected to the ferrule, and a shield part of the micro coaxial cable is electrically connected to the connector housing, and that the coaxial cable is micro coaxial cable.
