Office Action

§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 . Claim Objections Claim 10 is objected to because of the following informalities: Regarding claim 10, the claim recites various elements for example “a capacitor C1”, “a fifth circuit interface port” which should all be amended to be recited as “the capacitor C1”, “the fifth circuit interface port” as all those elements has already been introduced and recited in previous claims from which the claim depends. Appropriate correction is required. 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. Claims 1-10 are rejected under 35 U.S.C. 103 as being unpatentable over US8,282,256B1 hereinafter “Pike” in view of US10,512,144B1 hereinafter “Shen” Regarding claim 1, Pike discloses a Christmas decoration device (Col.1 L29-32: decorative lighting system not limited to Christmas trees) with optical fibers (Abstract L1-2: a lighting system for illuminating various structure using LEDs and fiber-optics), comprising a controller (Col.3 L 59-62: a master control), wherein the controller is connected with a plurality of light-emitting components (Col.3L37: at least one light source) in series (as shown in Fig.6, each LED [30] is connected in series via wire [33] to transformer [38]), the light-emitting components comprise light-emitting parts (Col.3L40-42: the light source comprised of a light emitting diode) that are connected with the controller in series (as shown in Fig.6, each LED [30] is connected in series via wire [33] to transformer [38]), each light-emitting part is connected to an optical fiber part, the optical fiber part is configured to transmit light emitted by the light-emitting parts (Col.4L59-53: light transmitter is used to transfer the light emitted from the light source; the light transmitter comprised of string configuration and a fiber-optic cable), Pike does not explicitly disclose: controller comprises a control circuit, and the light-emitting parts realize color switching under a control of the control circuit.
