Office Action

§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 2-4,8-10 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 2 is confusing because claim 2 line 4 calls for “a second drainpipe”; however, there was never a “first drainpipe” previously recited. Claim 2 is confusing because claim 2 line 5 calls for “a third drainpipe”; however, there was never a “first drainpipe” previously recited. Claim 3 line 2 calls for “a source of wash fluid”; claim 1 line 15 calls for “a first wash fluid”; it is unclear if and how they are related. Claim 4 line 2 calls for “a source of wash fluid”; claim 1 line 16 calls for “a second wash fluid”; it is unclear if and how they are related. Claim 8 is confusing because claim 8 line 4 calls for “a second drainpipe”; however, there was never a “first drainpipe” previously recited. Claim 8 is confusing because claim 8 line 5 calls for “a third drainpipe”; however, there was never a “first drainpipe” previously recited. Claim 9 line 2 calls for “a source of wash fluid”; claim 7 line 17 calls for “a first wash fluid”; it is unclear if and how they are related. Claim 10 line 2 calls for “a source of wash fluid”; claim 7 line 18 calls for “a second wash fluid”; it is unclear if and how they are related. Allowable Subject Matter Claims 1,5-7,11 are allowed. Claims 2-4,8-10 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include 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: The prior art of record either alone or in combination fails to teach a drainpipe comprising an elongated member, said elongated member comprising: (a) a first conduit disposed on an upper portion of said elongated member, said first conduit comprising at least one first orifice disposed on a bottom surface of said first conduit; (b) a pair of second conduits disposed on two sides of said first conduit, each second conduit of said pair of second conduits comprising at least one second orifice configured to fluidly connect a lumen of each said second conduit to an environment outside of said elongated member; and (c) a third conduit disposed on a lower portion of said elongated member, said third conduit comprising two sides and at least one third orifice disposed on each of said two sides of said third conduit, said at least one third orifice configured to receive fluid from the environment outside of said elongated member and said first conduit is configured to be fluidly connected with said third conduit through said at least one first orifice, wherein a first wash fluid is receivable at said first conduit and dischargeable through said at least one first orifice into said third conduit and a second wash fluid is receivable at one or more second conduit of said pair of second conduits and dischargeable through said at least one second orifice to the outside environment before entering said third conduit through said at least one third orifice.
