Office Action

§102 §112
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 . Claim Rejections - 35 USC § 112 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. Claims 1-20 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. The limitation “different specifications” in claim 1 is vague. It is unclear to Examiner that the different specifications being referred to different configurations, different sizes, different positions or other meaning? The other claims 2-20 are being rejected due to their dependency. Claims 3-5, 12-14, 16-18 recite the limitation "the upper end" in line 3 of the claim 3. There is insufficient antecedent basis for this limitation in the claim. The claims 4-3, 12-14 & 16-18 are being rejected due to their dependency. Claims 11-14 recite the limitation "the endoscope mask" in line 2. There is insufficient antecedent basis for this limitation in the claims. Claim Rejections - 35 USC § 102 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 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 – (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. Claims 1-2 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Bettuchi (US 2011/0152777). Regarding claim 1, Bettuchi discloses a sealing cap 10 with adjustable aperture, comprising: a fixing seat 70; a cover body 14, which is detachably mounted on the fixing seat 70, see Fig. 1; and a sealing component 24 used to adapt to endoscopes of different specifications (different configurations, positions or different status); one end 30 of the sealing component is set on the cover body 14, and the other end 32 of the sealing component is connected to the fixing seat 70, see Fig. 4A. Regarding claim 2, wherein the sealing component 24 includes: a membrane 26, a rotating inner sleeve 30, and a rotating outer sleeve 38/40 for driving the membrane; one end 30 of the rotating inner sleeve 30 is rotatably mounted on the cover body 14, and the other end 32 of the rotating inner sleeve is connected to the rotating outer sleeve 38/40; one end of the membrane is connected (indirectly via the rotating inner sleeve) to the rotating outer sleeve, and the other end of the membrane is connected (indirectly via the element 32) to the fixing seat 70. PNG media_image1.png 694 990 media_image1.png Greyscale Claims 1, 6-10 & 20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Reddy et al. (US 2018/0133429). Regarding claim 1, Reddy discloses a sealing cap 26 with adjustable aperture, comprising: a fixing seat; a cover body 46 which is detachably mounted on the fixing seat, see Fig. 2B; and a sealing component 42, used to adapt to endoscopes of different specifications (open and close the slit, para [0081-0082]; one end of the sealing component 42 is set on the cover body 46, and the other end of the sealing component is connected to the fixing seat, see the marked-up Fig. 2C below. PNG media_image2.png 498 828 media_image2.png Greyscale Regarding claim 6, wherein a protruding platform 32 which is adapted to clamp the endoscope mask 12 in correspondence with the cover body, is set at the lower end of the fixing seat, para [0076] & Fig. 1A. Regarding claims 7-8 & 20, wherein a cushioning pad 94 is set at the upper end of the protruding platform 32, see Fig. 9A; wherein the cushioning pad 94 is a silicone pad (sponge pad) and/or rubber pad (sponge pad).
