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 . Specification The abstract of the disclosure is objected to because it is too long. A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b). Claim Rejections - 35 USC § 112 Claims 1-4 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 1, the grille is described to be “formed on a portion penetrated of the cut-out plate” formed out of the bottom plate, but is “formed in a size and shape corresponding to a diameter of a side on which a sound of the speaker is output.” Is the grille and speaker on the bottom (plate) or the side (plate)? This is unclear. Correction is required. Allowable Subject Matter Claims 1-4 would be allowable if rewritten or amended 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. The following is a statement of reasons for the indication of allowable subject matter: claims 1-4 are considered to be allowable over the prior art, as the prior art does not explicitly teach a chordophone (stringed musical instrument) in combination with the recited cutout, grille, speaker unit, control unit, and communication module that communicates with an external user module and app with lesson mode. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The references cited show related teachings in the art. Any inquiry concerning this communication or earlier communications from the examiner should be directed to JEFFREY DONELS whose telephone number is (571)272-2061.
