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. 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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claim(s) 1-20 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Di Teodoro et al, US Patent No. 7,400,804 . Regarding claims 1 , 9, and 17 , Di Teodoro et al disclose a monolithic or ribbon-like multi-core photonic-crystal fibers and associated method comprising: a substrate ( monolithic substrate having a width and length each larger than the thickness, and having one or more waveguides formed therein , col. 6, lines 15-25 ) ; a cladding formed on the substrate ( col. 6, lines 15-25 and col. 11, line 4+) ; a gain medium formed inside the cladding ( col. 9, lines 15-20 ) ; a pump light source configured to provide a pump light through a plurality of optical paths ( col. 11, line s 4-28 ) ; wherein a first portion of the gain medium receives a first portion of the pump light through a first optical path, and a second portion of the gain medium receives a second portion of the pump light through a second optical path, the second optical path separate from the first optical path ( see fig. 1B, pump laser 116A and 116B ) . Regarding claim s 2 and 18 , further comprising an input portion of the cladding, the input portion configured to receive an input signal; and an output portion of the cladding, the output portion configured to output an amplified signal in response to receipt of the input signal and the pump light ( see fig. 1B, including MO 110 to provide input signal and output signal 199 ) . Regarding claim s 4 and 10 , wherein the pump light source is integrated on a chip ( Pump 116 is a laser diode pump ) . 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. Claim (s) 3, 5-8, 11-16, and 19 -20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Di Teodoro et al . The teachings of Di Teodoro et al have been discussed above. Di Teodoro et al fail to disclose all the details of the components of the apparatus, such as the laser pump , the location of the pump signal, including a grading coupler for directing the pump light. However these features do not constitute to any inventive step, they are common f eatures in the art of optical amplifying signals. For instance, grading is commonly used for transmission and reflection to measure how much light passes through or is reflected by the optical element. Therefore, these additional features would have been an obvious extension as taught by the prior art. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Seo et al, US Pub. 2022/0231475 , disclose a laser radar device performing multi-stage amplification. Delavaux et al, US Pub. 2021/0328400, disclose a broadband ho-doped optical fiber amplifier.
