Office Action

§112
DETAILED ACTION 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. Claim 1-3 are rejected as failing to define the invention in the manner required by 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. The claim(s) are narrative in form and replete with indefinite language. The structure which goes to make up the device must be clearly and positively specified. The structure must be organized and correlated in such a manner as to present a complete operative device. The claim(s) must be in one sentence form only. Note the format of the claims in the patent(s) US PG-Pub 2006/0034472. Examiner’s Comment Examiners understanding of the specification, applicant invention is taking an already MEMS microphone module which outputs digital audio data using I2S and passing that data directly to a DAC for the analog audio data to be output/live performance and also recorded. However, looking at US PG-Pub 2006/0034472 Fig. 4, Fig. 7 & Fig. 9, shows a MEMS microphone-410 that will output digital output data and send it over to process on DSP-470 to then send audio signal to loudspeaker system-420 using I2S communication protocol. Then on [0024] the DSP is used in the term of “may”, meaning “DSP 170 where additional signal processing may occur”. Suggesting that the system does not actually needs the DSP at all and the signal from the MEMS microphone of Fig. 7 can be send directly to the loudspeaker of Fig. 9 since both using I2S communication. In addition, on YouTube, I2S: MEMS Mics and a PCM5102A DAC, July 18, 2023, Gadget Reboot, https://www.youtube.com/watch?v=OVSgRhFqcJE, shows the same inventive concept as the current application, of using MEMS microphone with I2S communication protocol with a DAC converter to take the MEMS mic signal and output it to the DAC. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to WILLIAM A JEREZ LORA whose telephone number is (571)270-5519. The examiner can normally be reached M-F 7am-9am and 11am-6pm. Examiner interviews are available via telephone, in-person, and video conferencing using a USPTO supplied web-based collaboration tool.
