Office Action

§102 §103 §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 . Election/Restrictions Applicant's election with traverse of Species III in the reply filed on December 3, 2025 is acknowledged. The traversal is on the ground(s) that the species are not independent or distinct because they are not mutually exclusive. Examiner agrees with Applicant, the restriction requirement, as set forth in the Office action mailed on October 16, 2025, has been reconsidered and the restriction requirement of is fully withdrawn. Once a restriction requirement is withdrawn, the provisions of 35 U.S.C. 121 are no longer applicable. See In re Ziegler, 443 F.2d 1211, 1215, 170 USPQ 129, 131-32 (CCPA 1971). See also MPEP § 804.01. Priority Acknowledgment is made of applicant's claim for foreign priority based on an application filed in China on December 30, 2022. It is noted, however, that applicant has not filed a certified copy of the Chinese application as required by 37 CFR 1.55. 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 6 – 7, 13 – 14 and 17 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. Claim 6 and 13 recites the limitation "the acquisition orientation” in line 4. There is insufficient antecedent basis for this limitation in the claim. Claim 7 and 13 recites the limitations "the optical output assembly”, “the output orientation”, “the first direction”, and “the second direction” in lines 2, 5, 6 and 8. There is insufficient antecedent basis for this limitation in the claim. Claim 17 recites the limitations "the optical output assembly” in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim 17 recites the limitations " the first direction is a direction faced by the first side surface, the second direction is a direction faced by the second side surface, and a third direction is a direction faced by a third side surface; and the first direction is the direction facing the first side, the second direction is the direction facing the second side, and the third direction is the direction facing the third side”. These limitations seem to contradict each other. Is the first direction facing the first side surface or faced by the first side surface? For purposes of art examiner, broadest reasonable interpretation will be exercised. 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 – 6 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Schirdewahn (US 2012/0001999).

Claim(s) 1 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Wada (US 2017/0115549). Regarding claim 1, Wada discloses an accessory device comprising: a first body (17) including a first functional assembly (camera 23/LEDs 45) (fig. 4; ¶43-45); a first connection assembly (37) connected to the first body (fig. 2; ¶35-36); and a second body (19) connected to the first connection assembly and including a first communication assembly (27) configured to be electrically connected to an electronic device (fig. 2; ¶27-30); wherein: the first functional assembly has a functional orientation (fig. 3, 5, 6, 8: such that the camera/LED may be tilted downwards from a start position to an end position); and a position relationship between the first body and the second body is changed according to the first connection assembly to change the functional orientation of the first functional assembly (fig. 3, 5, 6, 8: tilting changes orientation of camera/LEDs). Claim Rejections - 35 USC § 103 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. Claim(s) 8 – 18 rejected under 35 U.S.C. 103 as being unpatentable over Schirdewahn in view of Martinez (US 8,432,485). Regarding claim 8, Schirdewahn discloses an accessory device comprising: a first body (170) including a first functional assembly (camera 170) (fig. 3, 4; ¶21); a first connection assembly (172) connected to the first body (fig. 3, 4; ¶23); and a second body (173) connected to the first connection assembly and including a first communication assembly configured to be electrically connected to an electronic device (fig. 4; ¶25-26); wherein: the first functional assembly has a functional orientation (fig. 3; ¶23: such that the camera may be tilted downwards from a start position to an end position); and a position relationship between the first body and the second body is changed according to the first connection assembly to change the functional orientation of the first functional assembly (fig. 7, 9; ¶51: if tilt reaches threshold, mode switches). Schirdewahn also teaches an electronic device (100) including: a third body in a plate shape including a first side surface and a second side surface (110), a display assembly (120) having a display function being arranged on the second side surface (fig. 3, 5, 6, 9). Schirdewahn fails to explicitly disclose an electronic device including: a third body in a plate shape including a first side surface and a second side surface, a display assembly having a display function being arranged on the second side surface; a third connection assembly connected to the third body; a fourth body connected to the third connection assembly and including a third side surface and a fourth side surface that are opposite to each other, an input assembly having an input function being arranged at the third side surface; wherein a second communication assembly is arranged at the first side surface and configured to be electrically connected to the first communication assembly.
