Office Action

§102
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 Objections Claims 1-10 are objected to because of the following informalities: These claims should not include element numbers and phrases/words. Appropriate correction is required. 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. (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1 & 8 is/are rejected under 35 U.S.C. 102(a)(1)/102(a)(2) as being anticipated by Yang (U.S. Patent Number 11,216,948). Referring to claim 1, Yang discloses comprising a colon model (Figs. 10 & 11 & column 26 line 61- column 31 lines 39 & physical model) and a polypus model (Figs. 10 & 11 & column 26 line 61- column 31 lines 39 & polypus) detachably mounted on the colon model (Figs. 10 & 11 & column 26 line 61- column 31 lines 39); the colon model is opened and provided with polypus replacing points (Figs. 10 & 11 & column 26 line 61- column 31 lines 39 & nodes) for mounting the polypus model (Figs. 10 & 11 & column 26 line 61- column 31 lines 39 & polypus), the polypus replacing points are provided on different intestinal segments of the colon model (Figs. 10 & 11 & column 26 line 61- column 31 lines 39 & nodes); and the polypus replacing points are provided at a plurality of different positions in a circumferential direction of the colon model (Figs. 10 & 11 & column 26 line 61- column 31 lines 39 & nodes). Referring to claim 8, Yang discloses further comprising a decorative snap ring inserted and sleeved in an exposed end of the polypus model, the decorative snap rings all having the same external contour (Figs. 10 & 11 & column 26 line 61- column 31 lines 39 & polypus), and a plurality of sizes of slots at the inner side of the decorative snap ring being provided according to the corresponding polypus model and the polypus replacing points (Figs. 10 & 11 & column 26 line 61- column 31 lines 39 & nodes). Allowable Subject Matter Claims 2-7, 9 & 10 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: Claim 2 teaches colon model comprises a cecum segment, a sigmoid colon segment, and a rectal segment; and the cecum segment, the sigmoid colon segment and the rectal segment are each providing with one polypus replacing point. Claims 3-7, 9 & 10 are rejected due to their dependency on claim 2.
