Office Action

§102 §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 . Drawings The drawings are objected to under 37 CFR 1.83(a) because they fail to show the specific resistor as described in the specification. Any structural detail that is essential for a proper understanding of the disclosed invention should be shown in the drawing. MPEP § 608.02(d). Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. 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 7, 9 and 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. With regards to claim 7, applicant recites the limitation “a specific resistor” . Examiner is unsure what the specific resistor refers to. Is specific resistor one of the plurality of resistors or a different resistor. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of pre-AIA 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 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Ogata et al WO 2020121985. Ogata et al discloses a power divider circuit 1 comprising: an input terminal P1; a first output terminal P2, wherein the second terminal is connected to the input terminal via a first coil 21; a second output terminal P3, wherein the second output terminal is connected to the input terminal via a second coil 22; a resistor 41; and a capacitor 34, wherein the resistor and the capacitor are connected in parallel between the first output terminal and the second output terminal, the input terminal is configured to receive a first signal, the first output terminal is configured to output a second signal, and the second output terminal is configured to output a third signal. PNG media_image1.png 199 439 media_image1.png Greyscale Claim(s) 4 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Hayashi US 5650756. Hayashi discloses a dividing device comprising: a plurality of Wilkinson-type distribution circuits , wherein a Wilkinson-type distribution circuit of the plurality of Wilkinson-type distribution circuits includes an input terminal 22, a first output terminal 20, a second output terminal 21, a plurality of coils (L1 L1a) , a plurality of capacitors (C4 C4a) , and a plurality of resistors (R1 R1a) , wherein the plurality of coils, the plurality of capacitors, and the plurality of resistors are cascaded in two stages between the input terminal and at least one of the first output terminal or the second output terminal, a capacitor C4 of the plurality of capacitors and a resistor R1 of the plurality of resistors are connected in parallel between the first output terminal and the second output terminal, the input terminal is configured to receive a first signal, the first output terminal is configured to output a second signal, and the second output terminal is configured to output a third signal. PNG media_image2.png 270 416 media_image2.png Greyscale Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Huang et al US patent 8,937,517 titled “Spitter” . PNG media_image3.png 252 471 media_image3.png Greyscale Morgan US 12,489,413 titled “ Power splitter and associated methods”.
