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 . Status of Application This communication is responsive to the applicant's application filed 07/04/2024. Claims 1-10 are pending. 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. Claim(s) 1, and 8-10 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Tanaka et al (US-2013/0070951, hereinafter, Tanaka). Regarding claim 1, Tanaka discloses a microphone (Figs. 1, 3, 7), comprising: a housing (1); a printed circuit board assembled with the housing for forming a first cavity (121) and a second cavity (122) communicating with the first cavity (Fig. 3); a first chip component fixed with a side of the printed circuit board close to the housing and located in the first cavity, including a first ASIC chip (14) and a first MEMS chip (13); a second chip component fixed with the side of the printed circuit board close to the housing and located in the second cavity, including a second ASIC chip (16) and a second MEMS chip (15) (see Fig. 7); and a first metal layer fixed with the side of the printed circuit board close to the housing and surrounding the first chip component and the second chip component; wherein the housing is fixed with a side of the first metal layer away from the printed circuit board (see Fig. 14, para [0129]-[0133]). Regarding claim 8, see Fig. 14, and para [0131]. Regarding claim 9, see Figs. 2 and 3. Regarding claim 10, see Fig. 2 and 2 with holes 21, 22, 23, and 25. Allowable Subject Matter Claims 2-7 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 an Examiner's Statement of Reasons for Allowance: The closest prior art of Tanaka fails to disclose the limitations as recited in dependent claim 2. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Ghidoni et al, Ye, Miller et al, Zeng et al, Wang et al, and Gupta et al disclose various microphones including MEMS chip and ASIC chip.
