Disposition of Claims Claims 1-20 are pending and rejected. Claim Rejections - 35 USC § 112(b) 07-30-02 AIA The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. 07-34-01 Claims 1-18 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Regarding Claim 1, Claim 1 recites the limitation “a distal end of the shaft” on Lines 5-6. It is unclear whether this “distal end” is the same as the “distal end” previously recited on Line 3, or a separate, different distal end. For the purpose of examination, “a distal end of the shaft” is being interpreted as “the distal end of the shaft”. Regarding Claim 12, Claim 12 recites the limitation “a distal end of the shaft” on Lines 3-4. It is unclear whether this “distal end” is the same as the “distal end” previously recited on Line 2, or a separate, different distal end. For the purpose of examination, “a distal end of the shaft” is being interpreted as “the distal end of the shaft”. Regarding Claims 2-11 & 13-18, Claims 2-11 & 13-18 are rejected as being dependent upon claims previously rejected under 35 U.S.C. § 112(b). Claim Rejections - 35 USC § 102 07-06 AIA 15-10-15 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. 07-07-aia AIA 07-07 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – 07-08-aia AIA (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. 07-15 AIA Claim s 1, 3-4 & 6-20 are rejected under 35 U.S.C. 102( a)(1 ) as being anticipated by Lu et al.

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. 07-20-02-aia AIA 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. 07-21-aia AIA Claim s 2 & 5 are rejected under 35 U.S.C. 103 as being unpatentable over Lu et al. (hereinafter "Lu") (US 2019/0246884) in view of McCutcheon et al. (hereinafter "McCutcheon") (US 2007/0203396) . Regarding Claim 2, Lu discloses the endoscope device of Claim 1. Lu fails to explicitly disclose wherein the lens is a fisheye lens for wide angle viewing. However, McCutcheon teaches an endoscopic device (Fig. 1, 120; [0004]), comprising: a flexible shaft (Fig. 1, 130; [0004]) extending distally from a proximal part (Fig. 1, 125; [0004]) to a distal end (Fig. 1, 145; [0004]), the proximal part including a power connection (Fig. 2A, 210; [0034]), the shaft comprising: a fluid channel (Fig. 1, 710; [0004]); and an imager (Fig. 2A, 720; [0004]) directed distally from the distal end of the shaft (see Fig. 2A), the imager including an imager chip ([0029]) and a lens ([0029]); and wherein the lens is a fisheye lens for wide angle viewing ([0029]). The advantage of the fisheye lens is to provide a very wide angle view (McCutcheon; [0032]). Therefore, it would have been obvious before the effective filing date of the claimed invention to someone with ordinary skill in the art to modify the lens as disclosed by Lu, to be a fisheye lens as taught by McCutcheon, to provide a very wide angle view (McCutcheon; [0032]). Regarding Claim 5, Lu discloses the endoscope device of Claim 1. Lu further discloses a wireless data transmitter ([0039]). Lu fails to explicitly disclose a battery. However, McCutcheon teaches an endoscopic device (Fig. 1, 120; [0004]), comprising: a flexible shaft (Fig. 1, 130; [0004]) extending distally from a proximal part (Fig. 1, 125; [0004]) to a distal end (Fig. 1, 145; [0004]), the proximal part including a power connection (Fig. 2A, 210; [0034]), the shaft comprising: a fluid channel (Fig. 1, 710; [0004]); and an imager (Fig. 2A, 720; [0004]) directed distally from the distal end of the shaft (see Fig. 2A), the imager including an imager chip ([0029]) and a lens ([0029]); and a battery ([0035]). The advantage of the battery is to charge the endoscope when not in use so to be ready for use without further delay (McCutcheon; [0035]). Therefore, it would have been obvious before the effective filing date of the claimed invention to someone with ordinary skill in the art to modify the endoscopic device as disclosed by Lu, to include the battery taught by McCutcheon, to charge the endoscope when not in use so to be ready for use without further delay (McCutcheon; [0035]) .
