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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 9-10 are rejected under 35 U.S.C. 103 as being unpatentable over US1 as applied to Claim 1 above. Regarding Claim 9, US1 describes the optical adapter comprising a second optical connector (3) that is a second optical plug (30) on a second optical cable (4; see Fig 6 and [0074]-[0075]). US1 does not additionally the first optical connector is a first optical plug on a first optical cable. However, the structure of the adapter US1 is symmetrical, which would allow for physical connection of a plug identical to the plug of US1 to both sides of the adapter. Further, it is well-known in the art that an optical source/receiver connections may alternately be direct or remote via a fiber cable. Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to connect an additional plug on a cable, identical to the described plug of US1, to the adapter of US1 in place of the first connector of US1. The motivation for doing so would have been to allow for remote connection of the optoelectronic device. Regarding Claim 10, US1 describes the second optical plug as an MT ferrule (inherent to the structure of an MTP connector described at [0052]). The obvious adapter in view of US1 would have identical plugs, resulting in both the first and second optical plug comprising an MT ferrule. US1 is silent as to the material of the ferrule of the optical plug. Glass is a well-known material for forming ferrules of optical plugs. Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art to form the ferrules of both plugs in the obvious adapter in view of US1, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. The motivation for doing so would have been to make use of the known material qualities of glass in forming the ferrules. Conclusion The prior art cited in the attached form PTO-892 are made of record and considered pertinent to applicant's disclosure. The cited prior art describes various optical systems allowing for the connection of first and second interfaces with waveguides.
