Office Action

§102 §103 §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 Objections Claim 20 is objected to because of the following informalities: “the first floss receiving port the second floss receiving port” in lines 1-2 should read “the first floss receiving port and the second floss receiving port”. Appropriate correction is required. 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. Claims1-7 and 13 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. Claim 1 recites the limitation “floss” in lines 3, 5, and 6 which renders the claim indefinite as it is unclear if the “receiving floss” in lines 3 and 5 and “advance floss” in line 6 are the same floss or if different pieces of floss are being recited. Claim 13 recites the limitation "the surface" in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim Rejections - 35 USC § 102 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 and 3-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Achepohl et al. (US 20060011212, hereinafter Achepohl).

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. Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Achepohl et al.

Achepohl discloses the use of floss (abstract) but does not specify that the floss comprises a stiff threader portion and a flexible floss portion. Kalbfeld discloses the floss (10; figures 1-2) comprises a stiff threader portion (14a; figures 1-2; paragraph [0016]) and a flexible floss portion (14b; figures 1-2; paragraph [0016]). It would have been obvious to one of ordinary skill in the art before the effective filing date to have specified the floss of Achepohl to have a stiff threader portion and a flexible floss portion to be helpful for individual with dental appliances or braces because it allows the floss to be inserted between the dental appliance and the gum line (paragraph [0016]).
