Office Action

§102 §112
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 Claims 7-10 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. Regarding Claim 7, “the length of the spacers” and “the right angle vertical edge” lacks antecedent basis and is not positively recited. Correction is required. 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. (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 is/are rejected (to the extent understood) under 35 U.S.C. 102(a)(1) as being fully met by Schille (USP 4984499). Regarding Claim 1, Schille discloses a mouthpiece for playing a wind instrument, wherein comprising air chambers 17, disposed in the housing of the wind instrument; air pressure sensors 21, disposed at the bottom of the air chambers 17 for detecting air pressure changes within the air chambers 17; an air intake channel 16, disposed on the outer side of the air chambers 17, and when air is blown into the air intake channel 16, the air chambers 17 produce pressure changes, which are detected by the air pressure sensors 21; air vents 19, disposed on the air intake channel 16, are configured for airflow to enter the air intake channel 16 and be discharged from the air vents 19, and the path thereof changes. Claim(s) 1,2 is/are rejected (to the extent understood) under 35 U.S.C. 102(a)(1) as being fully met by Antaki (WO 01/43116). Regarding Claim 1, Antaki discloses a mouthpiece for playing a wind instrument, wherein comprising air chambers 17, disposed in the housing of the wind instrument; air pressure sensors 102,110,111, disposed at the bottom of the air chambers 17 for detecting air pressure changes within the air chambers 17; an air intake channel (not numbered, square openings on 10), disposed on the outer side of the air chambers 17, and when air is blown into the air intake channel, the air chambers 17 produce pressure changes, which are detected by the air pressure sensors 102,110,111; air vents 31-39,41-49 disposed on the air intake channel, are configured for airflow to enter the air intake channel and be discharged from the air vents 31-39,41-49, and the path thereof changes. Regarding Claim 2, Antaki discloses the air vents 31-39,41-49 are provided as a structure that runs through the top and bottom of the air intake channel (see Fig. 2: vents on top and bottom covered by reeds 15,20). Allowable Subject Matter Claims 3-6 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. Claims 7-10 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.
