Office Action

§102 §103
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 . DETAILED ACTION Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. 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) 1-8 is/are rejected under 35 U.S.C. 102(a(1)) as being anticipated by Min (US 20210037932). Regarding claims 1-8, Min discloses: 1. A high-precision smart ring, comprising a ring holder (100), wherein an accommodating cavity (“groove”) is formed on the outer circumferential side (110) of the ring holder (100) (paragraph 0049); a flexible circuit board (170) is laid in the accommodating cavity (“groove”); a blood oxygen emitter (172a) and a blood oxygen receiver (172d) are electrically connected to and disposed on the flexible circuit board (170) (paragraph 0049, 0065); a main control chip (paragraph 0065), an antenna (paragraph 0063), a storage battery (182), a charging interface (180a) (paragraph 0097) and a temperature sensor (176) are disposed in the accommodating cavity (“groove”); and the main control chip (paragraph 0065), the antenna (paragraph 0063), the storage battery (182), the charging interface (180a) (paragraph 0097) and the temperature sensor (176) (paragraph 0067) are all electrically connected to the flexible circuit board (170). 2. The high-precision smart ring according to claim 1, wherein an blood oxygen window is disposed on an inner-side wall surface of the ring holder; the blood oxygen emitter (172a) and the blood oxygen receiver (172d) are disposed at the blood oxygen window and towards the circle center of the ring holder; and the axial distance d between the blood oxygen emitter and the blood oxygen receiver at the inner-side wall surface of the ring holder (1) satisfies 3.8 mm ≤ d ≤ 7 mm (paragraph 0068-0074, 0085-0086). 3. The high-precision smart ring according to claim 1, wherein the blood oxygen emitters (172a) are provided in two (172b, 172c); the blood oxygen receivers (172d) are provided in one; the two blood oxygen emitters are symmetrically disposed on both sides of the blood oxygen receiver (paragraph 0068-0070). 4. The high-precision smart ring according to claim 1, wherein the blood oxygen receiver (172d) is circumferentially covered with a light shield (178-1, 178-2) (paragraph 0071-0072, 0074-0075). 5. The high-precision smart ring according to claim 4, wherein the light shield (178-1, 178-2) is formed and coated by a light shielding coating (e.g. filter) (paragraph 0071-0072, 0074-0075). 6. The high-precision smart ring according to claim 1, wherein the blood oxygen emitter (172b), the blood oxygen receiver (172d), the blood oxygen emitter (172c), the main control chip (paragraph 0065), the antenna (paragraph 0063), the storage battery (182), the charging interface (180a) and the temperature sensor (176) are arranged circumferentially around the ring holder (100) in sequence (Fig 1-2, 7a-7b). 7. The high-precision smart ring according to claim 1, wherein the ring holder (100) is provided with a through hole at a position corresponding to the charging interface (180a); and the charging interface (180a) is disposed in the through hole (paragraph 0097). 8. The high-precision smart ring according to claim 1, wherein the ring holder (100) is a thermally conductive metal ring (paragraph 0051, 0055); and the temperature sensor (176) is thermally conductively connected to the ring holder (100) (paragraph 0090-0091, 0095). Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
